What Do ANPR Cameras Look Like in the UK? How to Spot Them
By Scott, Clearfront founder
ANPR cameras are usually small rectangular units mounted on motorway gantries, roadside poles, bridges and police vehicles, almost always paired with a second unit that emits infrared so the plate stays readable at night. They are not painted yellow, they do not flash, and they are far easier to walk past than a speed camera. Here is how to tell them apart, and why spotting them matters less than people expect.
What does an ANPR camera actually look like?
Most fixed ANPR units are compact rectangular boxes in grey, white or black, mounted high and angled down at the traffic lane. Next to the camera you will usually see a second, similar-looking unit: that is the infrared illuminator, which lights the plate invisibly so the system reads it in the dark.
The giveaway is the pairing and the angle. A camera aimed squarely at the plate line of a single lane, with a partner unit beside it, is doing plate recognition. Cameras that sweep or rotate are usually traffic monitoring or CCTV instead.
How is that different from a speed camera?
Speed cameras in the UK are legally required to be conspicuous, which is why they are yellow. ANPR has no such requirement, so it is typically unpainted and unremarkable. If it is yellow and boxy, it is enforcement. If it is small, grey and paired, it is probably reading plates.
Average-speed cameras muddy this, because they also read plates, at entry and exit, to calculate your speed over a distance. Those are usually yellow too.
Do ANPR cameras flash?
No, not visibly. ANPR cameras light the plate with infrared, which the human eye cannot see, so the camera reads plates day and night without ever appearing to fire. Point a phone camera at one in the dark and you may catch the infrared as a faint glow the naked eye misses.
If a roadside camera flashed at you visibly, it was almost certainly a speed or red-light camera, not ANPR. No visible flash does not mean no read: on a covered road, assume the plate was logged.
Are ANPR cameras everywhere in the UK?
Effectively everywhere on the strategic road network, plus town centres, car parks, petrol forecourts and fuel stations, and on police vehicles as mobile units.
The Home Office's own impact assessment records more than 12,000 fixed camera sets and around 1,900 mobile cameras, submitting over 100 million number plate reads to national systems each day, held for up to a year. Those figures are published in the National ANPR Service data protection impact assessment ↗.
Is any of this Flock?
No. Flock Safety is a US company, and there is no confirmed deployment by any UK police force. The plate reading here is the national ANPR network, run by the police rather than a private vendor. The full explanation, including the UK businesses that share the Flock name and cause the confusion, is in are Flock cameras tracking UK drivers.
Does spotting them help?
Honestly, not much. There is no opt-out from ANPR, avoiding covered roads is impractical, and obscuring a plate is an offence. Knowing what the cameras look like is useful context, not a countermeasure.
What you can do is find out what is held on you. As the registered keeper you can make a subject access request for the reads on your vehicle, and complain to the ICO if it is refused. The process is in how to make a subject access request.
And the road network is the smaller half of the picture. Far more about you is sitting in public right now: the accounts tied to your name, the brokers selling your address, the credentials in old breaches. Clearfront scans that in one sweep locally and reports what is exposed. Install Clearfront free, or get the free removal guide.
Frequently asked questions
- What do ANPR cameras look like in the UK?
- Small rectangular grey, white or black units mounted on gantries, poles, bridges and police vehicles, angled down at a traffic lane and usually paired with an infrared illuminator alongside them. They are not painted yellow and they do not flash.
- How can I tell an ANPR camera from a speed camera?
- Speed cameras must be conspicuous by law, which is why they are yellow. ANPR cameras have no such requirement and are typically unpainted and inconspicuous. Average-speed cameras are an exception, since they read plates and are usually yellow.
- Do ANPR cameras flash?
- No. ANPR cameras illuminate the plate with infrared light, which is invisible to the human eye, so they read plates at night without any visible flash. A camera that visibly flashed at you was almost certainly a speed or red-light camera instead.
- Can I avoid ANPR cameras?
- Not realistically. The network covers the strategic road network plus town centres, car parks and forecourts, and there is no opt-out. Obscuring or altering a number plate to defeat it is a criminal offence.
