  • Police deploy drones for many reasons: Search and rescue, law enforcement, disaster response, and crash scene investigation;
  • Drones help police collect various types of data, including thermal imagery, zoom and visual data, and LiDAR mapping;
  • Best drones for police include the DJI M300 RTK, DJI M30 Series and DJI Mavic 2 Enterprise Advanced.

From finding missing people to mapping a crime scene, UK police forces are seeing the benefits of drone technology.

More and more Forces are embracing UAS (unmanned aircraft systems) to fight crime, keep their communities safe, and collect vital information.

Police drones enable officers to collect data and obtain real-time vital situational awareness, quicker and safer. It is also significantly cheaper than calling on the National Police Air Service helicopter. 



Police can use drones for:

  1. Finding missing people/searching for suspects
  2. Mapping a crime scene or for accident reconstruction
  3. Major incident response
  4. Gathering evidence
  5. Crowd control/pre-planning for a major event

This blog examines how police are using drones, with some real-world case studies.


Police Drones: Five Ways A Drone Has Helped Police Operations

The below examples showcase the best use-cases for police drones.


1: Finding Missing People

Using thermal and/or zoom cameras, drones can be used to find missing people.

There have been numerous cases of unmanned aircraft locating a missing person, when other methods have failed.

This video shows the moment that North Wales Police found a pensioner who had been missing for almost 24 hours. 



The team deployed a DJI M300 RTK and H20T camera, with thermal and zoom capabilities.

Lead pilot Sergeant Paul Terry said: “If the drone hadn’t of been there, he wouldn’t have been seen. It’s very likely he wouldn’t have been located that night and his life was saved because of that tactic.”

2: Accident Reconstruction

Deploying UAS for accident reconstruction cuts down the evidence-gathering process - taking less than 30 minutes for a job that used to take three or four hours.



Not only does this speed up the data-collection process, but also means that roads can be reopened faster and cuts down on officer on-scene times.

In just a single flight, drones can collect hundreds of images to create accurate and detailed 2D maps and 3D models for thorough accident investigation, including measuring skid marks, examining damage and streamlining communication between investigation teams.



The same application can be applied to mapping any crime or incident scene.

Find out more in our in-depth guide to using drones for crash-scene reconstruction.


3: Evidence Gathering

Drones provide a great way of collecting evidence - often with a unique aerial perspective.

Take Lincolnshire Police, for example. Using an unmanned aircraft with thermal capabilities, the drone team landed its first prosecution by uncovering a professional cannabis growing operation.

The footage was passed on to the investigating team to obtain a search warrant, and it was used in evidence at court 


A Force spokesman said: "We turned up and flew the drone 400ft across an open field, before hovering 50m from the property - and the heat source was obvious. The filming from the drone took one minute and 20 seconds, and it was only in the air for five minutes from start to finish.

"The drone provided us with visuals that couldn’t really have been done in any other way. Yes, the National Police Air Service helicopter could have done this, but this would have been at a cost of about £3,000 per hour. Instead, we did this with the drone as part of our routine duties."


4: Disaster Response

Drones are an essential tool to use during or following a major incident.

Every second counts, and drones can be deployed quickly and cost-effectively, reaching inaccessible areas and providing vital information about the crisis in real-time - all while keeping officers safe.

Police drones showed their worth during the Whaley Bridge dam incident in Derbyshire.

Derbyshire Constabulary deployed its fleet of DJI drones to monitor the extent of the situation and patrol the evacuated town following reports of attempted burglaries at empty properties.

These series of shots showed how the drone with zoom camera was able to obtain a crystal-clear view of the damage, from afar...





...while this image shows how the drone provided real-time information about the placing of bags of aggregate, by RAF Chinooks, and spotted for any breaches.



PC Tom Gee said: "If we didn't have the drone, somebody would have had to go up close to the damage - scaling down on a rope down the dam to have a look and putting their life at risk."

5: Crowd Control And Planning At Major Events

Surveillance by drone is an important and valuable part of policing - but Forces will not deploy unmanned aircraft to simply spy for no good reason.

Drones can be deployed by police for a range of observation missions, such as scouting key areas or suspects, obtaining vital situational awareness to help with deployment tactics, and monitoring crowd behaviour and movement. They are particularly useful for investigating suspects - especially those who could be armed - while maintaining a safe distance.

In one example of using drones for crowd control, Norfolk Police deployed unmanned aircraft on derby day between Norwich City and Ipswich at Carrow Road.

The drone offered a quick, cheap and readily-available solution which was impossible for fans to take counter-measures, and offered unique and better views. Sent into the sky, it scanned the crowd and sent live pictures to officers on the ground.

This situational awareness was vital and helped police make sensible and proactive strategic decisions. For instance, after the game, rival fans faced off outside the ground, separated only by a flimsy fence.

However, the drone footage of the crowd meant that police could see the situation developing early and were able to redistribute ground forces to the trouble spot and de-escalate the situation.


If persistent surveillance is required, a drone tether can be used to provide almost limitless flight time.


What Are The Best Police Drones? 

There are numerous drones that police can use, offering different capabilities and key features.

The DJI solutions that stand out are the M300 RTK, M30 Series, and Mavic 2 Enterprise Advanced.

You can find out how these drones compare by reading our M300 RTK vs M30 Series vs Mavic 2 Enterprise Advanced comparison blog or scroll down for an overview of each platform.



The M300 RTK is a powerful and highly versatile enterprise drone, making it an ideal aircraft for the police.

Its key benefits include:

  • Endurance: Fly for up to 55 minutes without payload, or up to around 48 minutes, depending on the payload used.
