Private drone surveillance of a company site in France: what the law allows, formats, prices
Burgled warehouses, stripped copper cabling, illegal dumping at the back of a brownfield plot: demand for drone surveillance in France now comes mostly from logistics, industrial and construction site managers. The drone replaces neither the guard nor the fixed camera: it adds a fast, reconfigurable aerial patrol that covers in ten minutes what a foot patrol walks in an hour. But private aerial surveillance is tightly bounded by French law: you watch your own premises, not the street, not the neighbours, not people. Here is exactly where the line sits, the intervention formats and the going rates.

What a drone adds to site security
Over a large footprint — a logistics platform, outdoor storage, a quarry, a brownfield awaiting redevelopment, a construction site compound — the aerial patrol answers three needs: cover fast (roofs, storage yards, rear fence lines nobody ever walks), see from above (an intrusion in progress, a concealed vehicle, a fence breach, displaced equipment) and document (timestamped images usable for a police report or the insurer). With a thermal camera it stays effective at night, when intrusions concentrate.
Academic literature confirms this positioning as a verification tool rather than a stand-alone solution: as early as 2012, Rachel Finn and David Wright showed in Computer Law & Security Review that civil drone surveillance uses were developing faster than their legal framing, and that acceptability depends directly on the privacy safeguards provided (see the study on Google Scholar). That is exactly what French practice requires: a strict perimeter and written rules.
The legal frame: your site, and only your site
The principle is simple: a company may have its own private footprint monitored, and nothing beyond it. Capturing images of public roads by drone is reserved for the authorities (police, gendarmerie, civil protection) under a specific legal regime: a private contractor does not "patrol" the street, follow an individual, or watch the surroundings beyond what protecting the site strictly justifies. Cameras point inward; neighbouring properties and public space are kept out of frame or masked.
As soon as people may appear in the images (employees, drivers, visitors), the GDPR applies: a defined purpose, limited retention, information of the persons concerned, and an impact assessment where monitoring is systematic — our guide to GDPR and professional drone work details these duties. Under French labour law, surveillance must not target employees: no activity monitoring by drone, and the works council must be informed and consulted before any system likely to capture their image. The flight itself follows the usual rules (zones, height, night flying) — overflying people remains prohibited.
Three formats: scheduled patrol, alarm response, permanent drone
In practice, three formats cover most needs:
- The scheduled patrol: a pilot comes at agreed intervals (weekend evenings, eves of public holidays, shutdown periods) and flies a defined circuit — roofs included, which no ground patrol does. It is the most requested format on construction sites, where equipment theft is soaring: see our guide to construction site surveillance and theft.
- Alarm verification: when an alarm triggers, a flight checks the situation before committing a human response — valuable on isolated sites.
- The permanent set-up: an autonomous drone-in-a-box flying automated rounds under supervision, or a tethered drone for a continuous viewpoint. These fall under the specific category and a heavier operational frame — our guide to autonomous industrial site surveillance compares them in detail.
In every case the contractor provides a written protocol: perimeter flown, camera field, fate of the images, who gets alerted.
2026 prices and how to budget
Orders of magnitude observed in France in 2026 (excl. VAT):
- One-off patrol with a pilot (30 to 60 minute pass, photo report): €250 to €500 per pass, tapering for a regular round.
- Night shift with thermal camera (several passes across a time window): €600 to €1,200 per night depending on site and airspace.
- Sensitive-period package (summer shutdown, year-end on a construction site): quoted case by case, typically €1,500 to €4,000 per month of spaced patrols.
- Permanent autonomous drone: capital and subscription costs of a different order — see the dedicated guide.
Pricing mostly depends on the airspace (built-up area, aerodrome proximity), the frequency and the expected reporting. This service draws on our security and surveillance drone offer: request a quote stating the town, the size of the footprint and the target time slots.
