Surveillance technologies occupy a growing place in security responses in West Africa: CCTV cameras, drones, communications interception, biometric recognition tools, data analysis, geolocation, etc. Their deployment is often presented as an obvious solution to terrorism, organised crime or urban insecurity.
Yet the central question is not whether these technologies “work” in theory, but whether, in West African political, institutional and social contexts, they can genuinely contribute to security without creating new risks.
What “surveillance technologies” cover
The expression covers several families of tools, already present or being deployed in the region:
- Urban CCTV: camera networks in city centres, on main roads and in public buildings, often linked to command centres.
- Communications surveillance: interception of calls and messages, analysis of telecoms metadata, tighter monitoring of social media.
- Biometrics and databases: recording of biometric data for identity cards, SIM cards, elections and borders.
- Drones and sensors: aerial surveillance of rural areas, borders, pastoral corridors or mining sites.
- Data analysis and algorithms: “big data” tools to cross-reference administrative registers, police files, images, and financial or telephone data.
These technologies are often acquired through bilateral partnerships (China, European countries, Israel, Turkey, etc.), multilateral programmes or commercial contracts with large security and telecommunications companies.
The promises: what these technologies can bring
In environments marked by rising armed violence, rapid urbanisation and pressure on the security forces, these tools can bring several benefits, under certain conditions.
Improved situational awareness
CCTV systems, drones and geolocation tools can:
- provide a near real-time view of certain sensitive spaces (main roads, markets, strategic buildings);
- help reconstruct routes (car bombs, abductions, movements of armed groups);
- better document certain incidents (riots, community violence, targeted attacks).
In contexts where human intelligence capabilities are limited or weakened, these contributions can be significant, notably in urban settings or on clearly identified corridors.
Support for investigations and justice
When properly regulated, surveillance data can:
- strengthen criminal investigations (movements, contacts, transactions);
- provide additional evidence before the courts;
- facilitate the dismantling of certain networks (trafficking, abductions, armed robberies).
This use, however, requires clear procedures for collection, storage, transmission and judicial oversight, which are still often incomplete or unevenly applied in the region.
Coverage of hard-to-reach areas
Drones and certain sensors can improve surveillance of:
- isolated rural areas, where armed groups and traffickers take advantage of the lack of state presence;
- porous borders, difficult to control with human resources alone;
- isolated strategic sites (mines, dams, pipelines, national parks).
In the Sahelian context, these tools can contribute to a better understanding of flows (weapons, fuel, gold, livestock), provided that the information collected is actually used and shared between services.
Structural limits in West African contexts
The potential benefits come up against several recurring limits, linked less to the technology itself than to political, institutional and social environments.
Technical capacity and sustainability
Many surveillance projects suffer from:
- a lack of maintenance: cameras out of service, software not updated, spare parts hard to obtain;
- dependence on foreign providers for installation, training and sometimes operation;
- insufficient local skills in cybersecurity, systems administration and data analysis;
- connectivity and power problems: power cuts, unstable internet networks, uneven telecoms coverage.
Without sustained investment in human resources, maintenance and cybersecurity, costly systems quickly become under-used or vulnerable to intrusion and misuse.
Institutional fragmentation
Surveillance systems are often spread across several actors: police, gendarmerie, army, intelligence services, municipal authorities, private operators. This dispersion leads to:
- duplication of tools and databases rather than their coordination;
- rivalries between services that limit information sharing;
- a lack of clear data governance (who collects, who has access, who controls?).
In contexts of political transitions, coups d’état or tensions between institutions, these systems can be exploited for the benefit of certain security apparatuses at the expense of an overall vision.
A mismatch with certain local realities
Surveillance technologies are generally designed for environments where:
- populations are largely registered (civil status, addresses, bank accounts, etc.);
- infrastructure is dense and relatively stable;
- criminal or armed groups depend heavily on formal systems (telecoms, banks, official transport).
In West Africa, a large part of economic and social life remains informal. Armed groups and criminal networks can:
- avoid conventional telecommunications (using messengers, radios, unregistered phones);
- blend into everyday flows (markets, pastoral mobility, informal transport) that are hard to track technologically;
- exploit areas without network coverage or outside the range of sensors.
Surveillance technologies then tend to be more effective at controlling ordinary people than at tracking the most dangerous and adaptive actors.
Risks of abuse and counter-productive effects
Beyond operational limits, the use of these technologies carries significant political and social risks, particularly in contexts of institutional fragility.
Infringements of freedoms and political surveillance
Without a solid legal framework or independent oversight mechanisms, surveillance tools can be used to:
- monitor political opponents, journalists and human rights defenders;
- identify and intimidate community or trade union leaders;
- restrict freedom of assembly and expression, notably during elections or periods of protest.
These abuses are not specific to West Africa, but they are particularly sensitive there given the frequency of political tensions and transitions and the central role played by the security forces in public life.
Deepening distrust of the state
In regions where the state is perceived as distant, partial or repressive, the proliferation of surveillance systems may be interpreted as:
- a desire to control people more rather than to respond to their needs;
- a sign of mistrust towards certain communities, notably young people, herders or minorities;
- a tool of discrimination targeting certain groups on the basis of their origin, religion or socio-economic profile.
This perception can fuel anger and hostility towards the security forces and, in some cases, lend weight to the discourse of extremist groups that denounce “unjust” or “humiliating” surveillance.
The risk of a false sense of security
Setting up visible surveillance systems (cameras, control centres) can give the illusion that the situation is “under control”, when:
- analysis and response capabilities remain limited;
- the root causes of violence (local governance, land conflicts, marginalisation, abuses) are not addressed;
- armed groups quickly adapt their modus operandi.
This gap between technological display and concrete results can, over time, deepen people’s disillusionment and further undermine trust in institutions.
Conditions for surveillance technologies to “really help”
The question is therefore not whether to reject or embrace these technologies wholesale, but to identify the conditions under which they can contribute to security without aggravating existing fragilities.
Part of an overall strategy, not a substitute
Surveillance technologies can be useful if they are:
- integrated into a broader security strategy including prevention, human intelligence, justice and local dialogue;
- geared towards clear and measurable objectives (for example, securing certain corridors or specific sites);
- accompanied by work on local governance, conflict resolution and the reform of security institutions.
They compensate neither for a lack of trust between the population and the security forces, nor for the structural weaknesses of the state.
Strengthening legal frameworks and oversight
To limit abuses, several elements are essential:
- clear laws on personal data protection, retention periods, and conditions of access and sharing;
- independent oversight authorities, with real resources, able to audit systems and receive complaints;
- judicial procedures governing the use of surveillance data in investigations and trials.
These safeguards are still being built in several countries, with varying levels of application depending on the political context.
Minimum transparency and dialogue with the population
Clear communication on:
- the objectives of surveillance systems;
- the areas concerned;
- citizens’ rights (redress, access, challenge);
can help reduce mistrust and foster social acceptance, provided that these commitments are credible and actually implemented.
Investment in human skills
The effectiveness of technologies depends on the ability to:
- train analysts able to distinguish weak signals from “noise”;
- develop multidisciplinary teams (technical, legal, sociological);
- ensure maintenance, cybersecurity and the continuous adaptation of systems.
Without this investment, systems risk becoming costly and under-used, or being misused by malicious actors, including within institutions.
Conclusion: a possible aid, but never a solution in itself
Surveillance technologies can help improve certain aspects of security in West Africa: better situational awareness, support for investigations, targeted protection of sites or corridors. Their usefulness, however, remains conditional on factors that go well beyond the technical dimension: governance, legal framework, human capacity, and trust between the state and the population.
Used without caution, they can strengthen political surveillance, deepen distrust, create a false sense of control and divert attention from the root causes of insecurity. Used with discernment, within a transparent and supervised framework, they can become one tool among others serving more coherent and more legitimate security policies.
