EPISODE INTRO
This is Episode 2 of Surveillance for Detection - where we look at how technologies are used along physical border lines.
In this episode, we begin by looking at the role of the IOM as a stakeholder in tech-assisted border violence, understanding both their complicity & hypocrisy. As well as understanding the legacy of EU Horizon projects in the Balkans?
Later on in the episode, we highlight some of the companies that are profiting from the militarisation of borders, and see how a ‘border industrial complex’ has developed between the EU and the Balkans, and how this intersects with facilitators of the ongoing genocide in Gaza.
And we conclude this episode by looking at the practicalities of border management on the ground alongside the landscapes of borders themselves - and in turn try to understand both what deterrence looks like as a crucial factor within border management, as well as the role of surveillance technologies within this.
MECHANISMS OF EXTERNALISATION; THE IOM, FRONTEX, & EUROPOL
So then, to begin, what role does the IOM play in providing surveillance tech to Serbia’s borders?
Let's first briefly contextualise ourselves on how the IOM works. To do so, let's listen to a quoted key finding from the 2023 report titled ‘Repacking Imperialism: The EU-IOM border regime in the western Balkans’:
“While the IOM positions itself internationally as an impartial expert on migration concerned with migrants’ well-being, its work on the ground shows that humanitarian concerns take second place to the interests of its donors. Indeed, within this framework the IOM principles of independence and impartiality are virtually impossible to maintain because this dependence, by default, requires the implementation of policies that represent the particular borders agenda as set out by the main donor(s)”
As described, the IOM is essentially an organisation that can be paid to implement the border agendas of states externally.
Alongside this, it is also important to consider the power that IOM - as the largest quote-on-quote ‘impartial’ organisation within the context of migration - has in shaping how people perceive and understand ‘migration’, and how dangerous having the power to shape understanding can be when held by an organisation that is clearly used as part of the imperial toolkit and as an extension the European border regime.
As is the case with IOM - whose monthly situational updates state regularly that the majority of people on the move who stay at reception centres in Serbia are economic migrants. From my personal experience working with and speaking to people on the move in Serbia over a period of two years, I know this is not the case. The overwhelming majority of people I spoke to on such topics were fleeing war or persecution of various kinds. It really begs the question of what specific methodologies the IOM uses to collect data for their reporting, and how they potentially use this data to skew results in order to fit the agenda of the states that sponsor them. In this case, one sponsor of the project that encompasses this reporting is the UK. A nation that is seeing a rapid increase in far-right, fascist organising, and a centre-right government who are increasingly pandering to these movements.

In regards to the surveillance technologies that are used on Serbia’s borders - we equally understand the IOM to be an imperial ally of the EU. Having assisted in the furthering of infrastructural and technological developments of Fortress Europe in Serbian territory.
One way in which the IOM actually procures and supplies these technologies and infrastructure for Serbian border police is through IOM programmes that are funded by the EU or other European countries.
For example, Denmark recently celebrated the end of a 4-year IOM programme worth 15 million euros, that amongst other objectives provided Serbian border police with training and ‘specific tactical equipment’ - including in March 2025 what was described as ‘the first specialised, multifunctional vehicle - the "Schengen bus" - which will be used primarily for border surveillance’. The so-called ‘Schengen bus’ appears to be a mobile surveillance system equipped with fingerprint scanners.
Between 2016 and 2025, we are aware of various EU-funded IOM programmes in Serbia that have allowed the procurement of technology such as unmanned aerial vehicles or drones, endoscopes and thermal imaging cameras, specialised binoculars, and CCTV-style surveillance within reception centres. This is in addition to physical infrastructure, services, and practical equipment for border authorities.
It has been difficult to accurately assess the total investment from the EU for IOM projects in the Western Balkans, especially considering there are projects we know have specifically supplied surveillance technologies to border authorities but were not listed in IOM's annual financial reports.
Though the project titled: ‘European Union regional support to protection-sensitive migration management systems in the Western Balkans’, which has seen collaboration between Frontex and other border authorities of various Balkan nations - known for their roles in illegal pushbacks - received nearly 11 million euros of funding from the European Commission using IPA money - averaging over 1.2 million euros per year. This project is known to have funded Albania’s progression toward having a biometric database that aligns with EURODAC.
Those not listed include a 2016 project worth 1 million euros - with nearly 400,000 euros specifically earmarked to provide Serbian border police with specialised surveillance equipment. As well as a 2018 project titled ‘EU support to border management phase III’ worth 3 million euros, whose activities included the procurement of specialised border surveillance equipment for Serbian border police on the Bulgarian and North Macedonian borders. Information surrounding the activities of phase I or II of this project is not publicly accessible.
We don’t know the reasons behind the lack of inclusion of certain projects within IOM’s annual financial reports, nor the lack of accessibility to certain phases of projects. However, to us, this certainly further highlights how entrenched the IOM is in Europe's border regime, its associated secrecy mirrored by the likes of Frontex and its collaborators, such as Serbia’s Ministry of Interior.
Over the years, even non-EU member countries, such as Japan and the US, have funded hundreds of thousands of euros into IOM projects that collaborate with Serbian border police.
Another avenue that highlights the IOM’s significance in enacting border externalisation in Serbia and other Balkan countries is their role as facilitator for EU policing agency activities in Balkan territories.
The previously mentioned 2024 review document of the 2022 Western Balkan Action Plan shows that the IOM was responsible for implementing projects that enhance the operations of both Frontex and EUROPOL in the Balkan region between 2021 and 2024.
The Frontex project, worth 5 million euros, broadly aims to enhance operations as well as existing status agreements with Western Balkan countries. Specifically within the timeline of the action, it is stated “[to] provide [Western Balkan] WB partners with technical, operational and other kinds of relevant support” as well as “[to] provide necessary personnel and resources to ensure the availability of EU assets, notably in Frontex joint operations” . These statements, though difficult to prove or disprove due to the lack of transparency in Frontex agreements with third countries, likely include reference to the use of surveillance technologies we know have been used to facilitate pushbacks across Western Balkan borders.
The EUROPOL project, this time worth 2 million euros, states its aim to “Make full use of the newly established EUROPOL Operational Task Force”. This project can be understood to follow on from the 2023 EUROPOL regulation reform, which essentially proposed a significant expansion of EUROPOL powers, especially when it comes to its digital surveillance capabilities against people on the move. What this looks like in the case of Western Balkan countries is the exchange of staff and field missions, and in turn, the implementation of EU-funded projects.
Investment in EUROPOL’s biometric systems and their capacity to collect and process biometric data on mass are key aspects of the reform. Considering Serbia’s database compatibility with the EURODAC system and the lack of transparency of EUROPOL field missions, there is serious cause for concern regarding EUROPOL’s ability to collect the biometric data of people on the move in Serbia or other Balkan countries under the guise of policing interventions.
Mass fingerprinting actions have already occurred on Serbia’s borders with the EU. In October 2023, a joint action between INTERPOL and the Serbian Ministry of Interior reported the fingerprinting of 516 people from within state reception facilities as well as at ‘wild’ locations near the border with Hungary.

Serbia is again not the only country whose border personnel have received technologies directly via EU-funded IOM programmes. The likes of Bosnia & Herzegovina, North Macedonia, and Albania have also received tech in this way.
Millions and millions of euros of EU taxpayer money have been pushed through the IOM to facilitate the extension of Fortress Europe into Western Balkan territories.
By platforming EU-funded programmes as an additional mechanism that equips borders and border police with infrastructure and equipment, the IOM are directly complicit, if not actively facilitating the pushbacks and further violations of human rights we know are both carried out by Western Balkan border personnel, and are at times facilitated by the surveillance technologies they have access to.
You will now listen to an extract of a testimony from January 2024. The account highlights the experiences of an individual pushed back from Serbia to Bulgaria. As you listen to this person's account, keep in mind this quote from the IOM’s mission statement, whilst they simultaneously bolster the capabilities of the Serbian border police.
“The Organization is guided by the principles enshrined in the Charter of the United Nations, including upholding human rights for all. Respect for the rights, dignity and well-being of migrants remains paramount.”
“The respondent, a male adult from Morocco, was walking on a highway from Belo Polje in Serbia to Pirot. He was together with a friend. About 2 km from Pirot, he described that several cars, recognized as police vehicles, arrived transporting four individuals wearing uniforms that resemble those of police officers. According to the respondent, the uniforms that the officers were wearing were completely black and they wore ski masks where only their eyes were shown. The officers forced the respondent and his friend into the same car and drove for about an hour. The car had tinted windows, so they couldn’t see where they were going. Ultimately they were brought to the border close to Bogoyna where they were forced out of the vehicle. It was close to a river. The police took the clothes, shoes and other belongings from them and smashed their phones. After that, the officers beat the respondent and his friend severely. He described this as (quote) ‘’it was as if they were beating animals.’’ (unquote). The two were hit and kicked for what felt like fifteen minutes. The officers sprayed pepper spray into the eyes of the respondent. Almost two weeks later, his foot was still swollen and legs still bruised as a result of the beating. The officers proceeded to then force both the men into the river. Afterwards they had to spend the night in the forest in Bulgaria.”
This account is typical of the levels of violence often enacted by Serbian authorities during pushbacks.

THE BORDER AS A LABORATORY; EU HORIZON PROJECTS
Now, the last avenue we will discuss that has allowed surveillance technologies to find their way to borders in Serbia is the EU Horizon Projects.
EU Horizon projects form part of the Research & Development arm of the European Union. However, significantly, there are multiple horizon projects - some completed, some ongoing - that aim to introduce various new techniques and technologies into border surveillance practices. Tens of millions of euros of European taxpayer money have been invested in the development of technologies used for detection and deterrence at borders.
Often, EU Horizon projects involve consortium members from non-EU and accession candidate states, as well as using these territories as testing sites. We see this as one of the many modes in which the EU is able to enact the externalisation of its ‘border management practices’. Serbia is no different in this regard.
The two projects that most significantly involve Serbia are titled: BorderUAS & ROBORDER. With BorderUAS involving the Mihaljo Pupin Institut - who are part of Belgrade University - as a consortium member. And ROBORDER using the Serbian - Hungarian border as one of its testing grounds.
Both projects - at least in part - incorporate the use of drones equipped with various tech to surveil land borders. As a landlocked nation situated on a popular migratory route, this arguably validates the use of Serbian geography and expertise in each of the projects.
BorderUAS, which started in 2020 and ended in 2024 and received nearly 7 million euros of funding, aimed to combine for the first time a lighter-than-air unmanned aerial vehicle with various surveillance tech for the purpose of low-cost and long-duration border surveillance operations. Specifically in rough terrain and extreme weather conditions.
ROBORDER, on the other hand, was a project that aims to develop a fully functional autonomous border surveillance system. What they describe this as is: “unmanned mobile robots, including aerial, water surface, underwater, and ground vehicles that will operate both independently and in swarms, incorporating additional sensors as part of an interoperable network.”
ROBORDER ran from 2017 to 2021, receiving nearly 8 million euros of EU funding. With the Hungarian National Police as a consortium member, the Serbian-Hungarian border was used as a test site for the project.
Given the timeline, the location of testing, and the history of those operating the test project, it’s a logical assumption that ROBORDER technology could have been used to facilitate at least some of the 99 recorded pushback incidents of over 1400 people documented in BVMN’s pushback database during the project's timeline.
What is consistent across most EU horizon projects - including both BorderUAS & ROBORDER - is the lack of concerns regarding the relationships projects have to border authorities who are known to have continually broken international law and fail to respect the rights of people on the move - the Hungarian and Bulgarian border forces, for example.
As well as prevailing issues concerning the data privacy of those the technologies seek to surveil, as well as a lack of transparency regarding testing practices and results. This means it is not clear what happens to the tech hardware once projects come to a close, nor what border policing operations the tech may be used to facilitate during testing.
Though this may not be surprising from the EU, given the established intent of its border management strategies - which are characterised by a disregard for the rights of those who predominantly come from the global south. It is more of a disappointment coming from the various consortium members involved in these projects. Especially the universities. Who, in at least the case of the University of Belgrade, has two faculties from within the same university umbrella, whose research on one hand highlights the role of the state in eroding people's rights, whilst on the other is developing the technologies that are assisting the erosion of rights.
THE EXTERNALISED BORDER INDUSTRIAL COMPLEX
In this and the previous episode, we have talked about various avenues that allow tech to be procured for detection and deterrence at EU and non-EU borders in Europe.
It is clear that there is a demand for both the development and implementation of border surveillance tech.
What we will now talk about are the companies that profit from this demand, and the emerging European and Balkan market for buying, selling, and advertising such tech.
In what has been described as a border industrial complex.
An analysis of tender winners from EU & IOM procurements for Serbia’s borders shows us that the companies that are profiting off of the EU’s violent border regime enacted on Serbia’s borders - of which tech-facilitated surveillance is a crucial element - are often Serbian or Balkan-based companies and manufacturers.
Or commercial sellers, who sell mainly products from Chinese manufacturers such as DJI-made drones or Dahua-made cameras.
One example of a Balkan company is Bulgaria-based OPTIX. In September 2025, a splurge of procurement tenders from Frontex and the Bulgarian border police earned OPTIX over 10 million euros. This was for various pieces of surveillance equipment, presumably to be directed to the EU’s external border with Turkey.
Since 2023, Optix has earned over 3 million euros of EU money from the sale of mobile surveillance systems for use on Serbia’s borders alone.

Though mobile surveillance systems are just the tip of the iceberg in terms of the range of surveillance tech OPTIX advertises on their website. In fact, they have a specific page dedicated to ‘solutions for border control’ offering various levels of large-scale technical systems for border surveillance at both land and sea borders.
Their ‘level 3’ system for land borders lists Mobile surveillance systems, Detention task force unit equipment, Sensor lines, Surveillance towers, Local Command centers, and Command center headquarters as part of the package.
An accompanying promotional video published back in 2021 states that OPTIX have implemented 9 border surveillance projects throughout the world already.

However, the offering of large-scale technical solutions for border management is not unusual within the market. Other large tech companies design and advertise similar border management solution packages.
Elbit Systems, for example. Well known for their legacy in facilitating and profiting from decades of illegal occupation and, more recently, the ongoing genocide in Gaza. The Israeli military technology manufacturer similarly offers their own integrated border solutions for both land and sea.
Plus, Elbit are no stranger to collaborating with the EU in the realms of border management. Back in 2020, along with Airbus and Israel Aerospace Industries, they were one of the recipients of 50 million euros worth of border surveillance drone contracts given out by Frontex.
In terms of the stakeholders and profiteers, the actual technologies being used and the ideologies that support such practices, there is certainly an intersection between the imperial practices exercised at borders in Europe and the Western-backed Genocidal ‘war’ in Gaza.
For instance, DJI, the Chinese-manufactured drones, known to be in the possession of Serbia’s border police as well as having been seen first-hand at the Hungarian border, are also known to be in possession of the IDF. As well as recent reports stating that the Israeli military is retrofitting commercial drones - including DJI models - so that they can be weaponised against Palestinians in Gaza.
Another example of this intersection was the recent pilot project led by Frontex & the Bulgarian border police that was mentioned in the previous episode. The pilot was testing out the first tactical drone surveillance system at the Bulgarian / Turkish border. A border - also discussed previously - that is synonymous with violent pushbacks of people on the move.
As mentioned, a key partner in the pilot project was Shield AI.
Shield AI is a US-based military tech manufacturer that developed the Nova 2 drone model that is currently being used by the IDF as part of the Genocide in Gaza. The Nova 2 is an AI-enabled small drone which has the ability to autonomously navigate and map complex subterranean or multi-story buildings without GPS, communications, or a human pilot. It was confirmed by the co-founder of Shield AI that the Nova 2 model could be customised for weaponisation.
Additionally, Shield AI have advertised its deep strategic partnership with Palantir. The large US data & security company who have been foundational to how Israel has conducted the Genocide in Gaza, as well as the 2025 Trump-orchestrated mass deportations by ICE.
The Bulgarian border-based pilot project itself concluded in July 2025. The surveillance system being tested was described by Frontex as follows:
“The mobile surveillance system integrated multiple data sources—including drone footage, infrared and daylight cameras, and inputs from smaller tactical drones—into a single operational picture using GIS tools. This allowed for real-time situational awareness to be shared securely with teams wherever needed.”
This 2025 pilot project is emblematic of what we understand a border industrial complex to look like in Europe. Headed by Frontex, the EU’s border guards, testing out new cutting-edge technologies on Europe's borders against people on the move. Awarding contracts to the likes of DAT CON - the Slovenian company who have sold their surveillance system services to the EU for millions of euros to be used by non-EU members Serbia & Albania, as well Shield AI - a company who have developed and sold technologies that are used by militaries across the world as well as having their high tech solutions used to enact an ongoing genocide. All of which were funded by the European taxpayer.
It is a conglomeration of an EU agency, a European company who have already made millions supporting Fortress Europe, and developing relationships with an international high-tech company that profits from and supports violence globally, which we understand to be quite representative of the border industrial complex in Europe as it stands.

The intersection of technologies used for both military and border surveillance purposes can also be seen within the EU’s Horizon projects. For example, the ROBORDER project. This project, which tested autonomous swarms of surveillance drones on the Serbian-Hungarian border, did not rule out the potential use of the developed tech within a military environment.
ROBORDER documents explicitly state that “a significant body of the work done in the area of Unmanned systems and passive radar has so far been motivated and funded by military applications, so the results of this project have the potential to be used back in the defence sector.”
Additionally, Israel was listed as a ‘country collaborator’ as part of the ROBORDER project - though the details of this collaboration were not stated publicly.
When discussing what can be understood as Europe’s border industrial complex - the proximity of stakeholders and collaboration with both a state committing genocide and the companies that facilitate and profit from such war crimes is at the very least deeply worrying.
Considering the demand for technologies to be used to facilitate the perpetration of international human rights law - be this violent pushbacks on Balkan borders, or the slaughter of civilians in Palestine - there is fertile ground for tech to be tested and developed, and large profits to be made with total impunity for both states and private companies. With the information gained from the use of tech in both scenarios effectively increasing the capabilities of imperial states to violate the rights of those from the Global South.
ACCOUNTS FROM THE BORDERLANDS
As part of this research project, we undertook various field trips, including visits to border areas between Serbia with Bulgaria and North Macedonia.
One of the most significant takeaways from these trips was being able to see these border landscapes first-hand. From this, we could gain an understanding of which of the technologies available would actually be the most effective in surveilling people's movement and achieving the goals of the EU-funded border regime.
The landscapes that encompass the borders between Bulgaria and North Macedonia are similarly mountainous, with the latter being coated in denser forests. With each landscape exposed to temperature extremes throughout the seasons.
Almost all entry points of irregular movements into Serbia involve crossing a landscape of this kind. Whether it is the Balkan mountains that provide the geographical barrier with Bulgaria or the Sar mountains with North Macedonia and Kosovo.
Whilst visiting the Serbian-Bulgarian border, we discovered a large fixed surveillance system topped with a remote camera and a plaque stating its construction was proudly EU-funded. The remote camera was likely operated from the nearby border police station in the village of Kalotina on the Bulgarian side.

On the Serbian side, the areas we chose to visit are declared as areas for the construction of new, similar, fixed surveillance systems as a result of the previously discussed 2024 EU-funded tender won by DAT CON.
The forests surrounding the Serbian town of Dmitrovgrad - not many kilometres from the sites we visited - are well known as both a popular irregular crossing point from Bulgaria to Serbia and an area in which violent pushbacks are regularly carried out by Serbian authorities.
The landscape shows this.
We saw many discarded and ripped-up ID cards from the registration of Bulgarian reception centres. As well as old clothes and shoes - either discarded after enduring the lengthy and challenging walk through this landscape, or possibly the result of forced undressings imposed by border police.
The forced undressing of people on the move is not uncommon as a tactic used by border personnel to inflict further violence within already illegal pushbacks.
For instance, in February 2024, footage of a pushback from Serbia to North Macedonia showed over a dozen people who had been stripped and forced to walk back across into North Macedonian territory during freezing winter temperatures. This was actually a rare instance when issues of border violence along the Balkan migration routes got picked up by mainstream news outlets in Western Europe - for example, The Guardian ran this story.

Returning to the border with Bulgaria. Pushback testimonies from those who were forced back across the border - around the town of Dimitrovgrad - are characterised by vehicles. By this I mean that many of the initial apprehensions described in the testimonies occur by Serbian police officers within vehicles on a paved road, who then proceed to take people to a point closer to the border itself and force them to walk back - often inflicting violence along the way.
Just as you would have heard in the previous testimony extract.
There is a specific road identified in testimonies. This road is the 429 running almost parallel to the Bulgarian border, on average, only a few hundred metres into Serbian territory. During our visit, we drove down the 429 as much as the surface allowed. The road itself was relatively newly paved for roughly 10 km from Dimitrovgrad heading southwest until the landscape became significantly more rocky and jagged - and seemingly impossible to navigate by foot. At this point, the road paving ceased.
The purpose of this paved section of the 429 seems to be to facilitate border patrols by vehicle and, in turn, pushbacks. Likely, it had been paved for this reason alone. It seems that using this newly paved road, regular police patrols facilitated by the surveillance of drones that have been reported to fly over this border, plus the soon-to-be-constructed fixed surveillance system, is at least in part the system of tech-facilitated surveillance in this particular stretch of border.
It’s worth noting that during our trip, this stretch of road was patrolled by both Serbian and Frontex police vehicles, even during the day, whilst most border crossing attempts happen at night.
During a trip to the border with North Macedonia, we visited a section of border near the town of Presevo - home to the largest currently active reception centre in Serbia with a capacity of 640.
Geographically, this section of the border exhibits a rare flat valley bottom between the Sar mountains to the West and the Kozjak mountains to the East - created by a glacier around 20,000 years ago.
Now, the flat base of this glacial valley provides a scarce break in the mountainous landscape that runs along all of Serbia’s southern borders. As a result, this area has been used as a crossing point into Serbia with fluctuating popularity over the years.
Consequently, a short run of border fence stretching 6km as the crow flies has been built by Serbian authorities along this relatively flat stretch of border.

It is worth noting that this area is highly militarised due to its proximity to the Kosovan border, as the Presevo valley is located on the boundary of the ‘Ground Safety Zone’, a former 5km wide demilitarised zone between Serbia and Kosovo, created as a part of a 1999 agreement that established new basic relations between modern day Serbia & Kosovo at that time. The Presevo valley was also the location of a 2001 Albanian-led insurgency, which resulted in the abandonment of the Ground Safety Zone. Albanians also sometimes call this region eastern Kosovo, as it was considered part of the geographical region of Kosovo until the end of World War II. In the present, it is home to the majority of the Albanian population in Serbia.
Now I will describe an ethnographic account from our field trip to this border area. This account provides a snapshot of the complex ethnic dynamics in this region and how they intersect with the contemporary EU-funded border regime. Whilst in turn highlighting the use of surveillance technologies enacted in this border area.
“We walked up a farm track to a point where we could see the border fence. At the end of the track there was an open hut full of sheep and animal feeding stations. You could see the border fence lining the crest of the hill above the trees where the land was more bare. There were two officers stationed at some sort of checkpoint around 800m from where we stood. They had a vehicle with them and what appeared to be some device situated upon a tripod. A young man around 20 years old called out to us from within the open hut. He said he thought we were Syrian. He told us how almost every night or morning he sees people coming down the hill through his farm. He pointed to a tap and told us this is so they can get water, and when he sees people coming through his land he tells them to hurry or the police will catch them and take them back. We asked about the officers on the hill and he told us they were Serbian, and that most nights he sees drones flying over the border. 20 days is the longest period in the last 5 years he hasn't seen anyone coming down from the border through his farm. Pointing to the Serbian side of the border, he explained that everyone in a 9km area is Albanian, himself included. He said they had also been the victims of conflict.”
FACTORS OF DETERRENT
To conclude this episode, we will look at how measures of deterrence have proven to be a crucial factor as part of EU border management practices, how surveillance technologies are used as measures of deterrence, and how this intersects with the landscapes and geographies of border areas. To do this, we will compare what EU-funded border management looks like at Serbia’s borders with Hungary in the north and Bosnia to the east.
Looking at the border with Hungary. The area of land has been regularly used as a crossing point into the EU for around a decade now. Here, the landscape is relatively flat and sporadically forested.
Despite at least 16 documented landscape-related border deaths in this area - as an irregular border crossing point, it is less geographically challenging than others. This has likely contributed to its popularity as an irregular entry point to the EU.
As a result, in 2015 Hungary built a 13-foot-high fence along the 110-mile-long border - the fence is double-lined so that a road allowing border police patrols exists between two fences, as well as the fences themselves being lined with razor wire and CCTV-style cameras. However, the fence itself has shown to be ineffective at actually reducing the flow of migration. More than anything else at this point, its existence is mostly symbolic of Hungary's far-right and hyper-nationalist approach to matters of migration - an approach that 10 years on from 2015 is being mirrored by EU member states at large.

The idea of border infrastructure as well as surveillance technologies being largely symbolic, is significant when we look at the role surveillance tech has as a deterrent.
For example, the 2023 special operation that was carried out on the Serbian-Hungarian border was highly militarised and technical - with authorities reported to have mobilised both drones and helicopters to facilitate the eviction processes of informal living sites. In response to the operation, patterns of migration through Serbia and toward the EU were altered. Routes from Serbia toward Bosnia, then onto Croatia became more popular. With the most popular crossing area surrounding the city of Loznica. The landscape here is characterised by steep mountainous terrain, with the Drina river forming the natural border between the two states, crossed by those attempting to seek sanctuary in the EU.

SOURCE: photo (2024)
The Drina is unpredictable, with strong currents and severe winter temperatures. From the data available, between 2016 and 2025, the border between Serbia and Bosnia has claimed at least 101 lives, making it the most deadly of Serbia’s borders. 98 of those who have been killed by this border were found to have drowned.
When we compare the characteristics of Serbia’s borders with Bosnia in the West, opposed to Hungary in the North, we can see that despite the varying nature of both borders, a deterrent factor remains crucial to how border management is executed at each place.
For example, on the one hand, the Serbian-Bosnian border is naturally geographically treacherous and as a result deadly. With any implemented border infrastructure being mostly analogue in the form of watchtowers, which are few and far between, and with little known or reported use of surveillance tech. Plus, although pushbacks do occur from Bosnia to Serbia, in comparison to some of Serbia’s other borders, relatively few are reported.
On the other hand, as discussed, the Serbian-Hungarian border is highly infrastructured with regularly reported use of surveillance tech such as drone flights, as well as being known to be a so-called ‘pushback hotspot’ along the Balkan migration route.
Factors of deterrence are a universal trait of border management strategies that oppose people's freedom to move.
At the border with Bosnia, this deterrence is present naturally through the treacherous geography within the landscape, and as a result, less tech and infrastructure is necessary, and direct police violence is less widespread as an alternative force of deterrence.
Whereas at the border with Hungary, where the landscape is more enabling of movement, artificial deterrent measures are required to meet the requirements of a ‘border management strategy’. Here, deterrents take the form of militarisation. The border is highly infrastructured, technical, and characterised by violent pushbacks. Pushbacks are already understood to be the EU’s de facto deterrence against movement across borders.
On Serbia’s borders, it is clear that surveillance technologies, which are significantly funded by the EU, are increasingly forming part of the deterrent factor within the European border regime that is exhibited here.
Though what is alike in both natural and artificial modes of deterrence is that when strategised within border management, they share the modus operandi of subjecting people on the move to violence.
In the case of Serbia, this means risking life in dangerous geographies to avoid apprehension or risking the body at the hands of tech and infrastructure that facilitate direct police violence.
In both cases, this is EU-funded state violence.
