Security drones
Security drones give a site a fast, high view of perimeters, yards and alarm points, by day and at night. This overview explains the main types, what a full drone security system includes, the UK rules at a high level and how to choose. Forge Robotics helps you match the option to the task, source the drone, brief an authorised operator and connect it to the systems your control room already uses.

The basics
Security drones are unmanned aircraft used to protect a site: patrolling perimeters, checking alarms, following an intruder from above and giving a control room a live picture. Most carry a zoom camera and a thermal camera. They add a fast aerial view to CCTV, guards and fences; they do not replace them.
Drone security in the UK is used mostly on large outdoor sites where fixed cameras leave gaps: logistics yards, utilities, solar farms, ports, construction sites and estates. The drone is one part of the system. Who flies it, what triggers a flight, where the video goes and who responds matter as much as the aircraft. Forge Robotics does not fly drones or hold CAA permissions; flights are carried out by an authorised operator.
Types
There are three main types of drone security. Tethered drones hover over one spot on a powered cable for long periods. Docked drones live in an on-site dock, launch on a schedule or an alarm and return to charge. Piloted drones are flown by hand by a pilot on site. Each suits a different job.
The system
A drone security system is more than the aircraft. It includes the drone and its cameras, a dock or tether where used, software to plan missions and take alarm triggers, an authorised operator and remote pilot, a link to the control room, rules on recording and retention, and a clear plan for who responds.
01
Zoom and thermal cameras, lights or a speaker where useful, rated for UK wind and rain.
02
How the drone launches, lands and charges, and the power and data that needs.
03
Routes, schedules and alarm triggers, and a live view for the remote pilot.
04
Who flies it, and the CAA authorisation that flying needs.
05
Video and events reaching the people and systems that act on them.
06
Recording rules, retention, signage, and who goes when the drone finds something.
Autonomous drone security, where flights launch and run themselves, still keeps a person in the loop: a remote pilot supervising and a control room deciding what happens next.
Docks
A drone in a box keeps the drone in a weatherproof drone dock on site. When a schedule or an alarm calls for it, the dock opens, the drone launches, flies a planned route under a remote pilot’s supervision, streams video to the control room, then lands back in the dock to charge and wait for the next mission.
A drone in a box solution needs mains power, a reliable data link, a clear launch area and an operator with the right CAA authorisation. Examples of dock makers include DJI (Dock), Heisha, Percepto and Skydio (Dock), named here as examples only. Routes, authorisation, privacy duties and site needs for docked patrols are covered in detail in our guide to docked drones and drone security patrols in the UK.
UK rules
Security drones in the UK are regulated by the Civil Aviation Authority under the UK drone regulation, and recording people brings UK GDPR duties. Routine, within-sight flying sits in the open category; remote, automated or beyond-sight flying needs an operational authorisation from the CAA, decided case by case. A site also needs a privacy assessment.
This is a summary, not legal advice. Authorisation is never routine; check the current CAA and ICO guidance and plan any operation with an authorised operator.
Choosing
Choose between security drone companies on the job, not the specification sheet: how the drone performs at night and in UK weather, whether a dock or tether suits the site, who will be the authorised operator, how alarms reach the control room, the privacy controls in the software and the support available in the UK.
| What to compare | Why it matters | What to ask for |
|---|---|---|
| Drone and sensors | Night and weather performance decide most security use | Thermal and zoom cameras, wind and rain limits, flight time |
| Dock or tether | Decides whether the system can respond without a person on site | Charging time, weather sealing, power and data needs |
| Operating model | Someone authorised has to fly it | Who is the operator, and what CAA authorisation they hold or will apply for |
| Software | Alarms must reach people who act on them | Mission planning, alarm triggers, export options and APIs |
| Privacy by design | UK GDPR applies to recorded footage | Recording controls, retention settings, encryption and DPIA support |
| UK support | A grounded drone protects nothing | Local service, spares, response times and training |
Criteria, not a ranking. The right choice depends on the site, the threats and the people who will respond.
The same questions apply to drone in a box companies and to tethered systems. For inspection rather than security work, see industrial inspection drones, and for ground patrols, see robot security patrols.

Your systems
Security drones connect through their own software, which can usually take an alarm as a launch trigger and share live video or events. A VMS (video management system) or alarm platform then needs to receive them. What works depends on the drone software and the systems and versions your site runs, so connections are scoped site by site.
Forge Anvil is being developed to bridge robot software such as ROS 2 and a site’s own systems (for example VMS or alarm platforms) through APIs where possible. It is designed to put drone events where the control room already works. Read how Forge Anvil is designed to work; on the ground, the same applies to quadruped robots.
A security drone is an unmanned aircraft used to watch over a site: patrolling, checking alarms, tracking an intruder from above or giving a control room a live view. Most carry a zoom camera and a thermal camera. Security drones can be piloted, tethered to a ground unit, or kept in an on-site dock and flown remotely.
A drone in a box is a drone kept in a weatherproof dock on site. The dock opens, the drone launches on a schedule or an alarm, flies a planned route, then lands back in the dock to charge. A remote pilot supervises. In the UK this kind of flying normally needs operational authorisation from the CAA.
Yes, within the rules. As at 21 October 2026 the CAA requires registration and IDs for most drones, and operations beyond the basic open category, including flying beyond visual line of sight, need an operational authorisation. Recording people also brings UK GDPR duties, which the ICO’s surveillance guidance explains. Authorisation is case by case, not routine.
A docked drone can launch and fly a route without a pilot on site, but a remote pilot still supervises, and flying beyond the pilot’s sight needs an operational authorisation from the CAA. As at 21 October 2026 that authorisation is applied for under the CAA’s specific category process. It is granted case by case, not assumed.
Most do. A security drone with a thermal camera can pick out people and vehicles by their heat at night, in shadow or through light vegetation, where a normal camera sees little. Thermal is usually paired with a zoom camera, so an operator can confirm what triggered the alert before anyone responds.
Often, but it depends on the drone software and the systems you run. Many drone platforms can take an alarm as a launch trigger and share video or events. Forge Anvil is being developed to bridge robot software and site systems such as VMS or alarm platforms through APIs where possible. Connections are scoped site by site.
A security drone covers large outdoor areas quickly from above and reaches an alarm point fast. A security robot dog walks a route on the ground, goes indoors, climbs stairs and stays out for longer in most weather. Many sites would use them for different jobs; the task and the site decide which fits.
Get started
Tell us the site, the security task and the systems your control room works from. We look at whether a drone fits at all, which type, what the rules and the site require, and how alerts would reach the right people, then help you source the drone and brief an authorised operator.
