What Type of Camera are These??
Discussion
Hey guys!
Just got back from a Cardiff to Newtown (mid Wales) journey to take my 260Z for media blasting. But that's another story!
Just passed Builth Wells near Llanelwedd on the A483, I noticed these very odd looking cameras which I've not seen before. Two on one pillar each pointed at the road. They are painted black. They looked pretty new and last time I drove the road about 2 months ago, I cant say I saw them there.
Anyways, I snapped a picture! Anyone know what they are?

Traffic monitoring. They are what give the feed to traffic updates on google maps etc. They record VRN each time you pass one. They count the number of vehicles and time the difference to work out out traffic desity and speed. the data is live and is instantly deleted. The algorithms are pretty rough and ready because they have to take into account vehicles that turn off or stop between cameras.

I wasn't under the impression data was deleted 'immediately'. Speaking with a policeman previously, I was told they'd tracked down a questionably-used Transit and an accomplice by trawling ANPR data from roadside cameras and spotted patterns?
I believe it's two different systems - Police/HA have their own. The other (for commercial uses) is separate (at least I think that's the official line, but in this day and age ....)Someone I know who has seen the HA system working, said you'd be surprised how widespread it is !!
The police have the ANPR cameras that are linked to their database, these can tell if a vehicle that passes it has any "Markers" against it. This means they can track the movement of suspect vehicles. They also do the usual stuff, no insurance, tax, MOT etc. so if there is a police patrol nearby they can be alerted to stop the vehicle.
The HA have 3 different types of cameras. There are some similar to ANPR cameras, they read the last 3 digits of number-plates at one location, then see how long it takes for the majority of those number-plates to reach the next location, these then give you those messages "12 miles to J##, 10 mins" it's a completely automatic system, nothing to do with enforcement, and completely different to the police type ANPR cameras.
The Main type of camera that the HA have, are just CCTV traffic cameras, used mainly to spot reported problems, ie. if something is reported as being in the live c/way, unless it can be confirmed, and the exact location tied down to a marker-post, only 50's "INCIDENT" can be set on the signals, now if it can be seen on the CCTV, then the exact location is confirmed, and signals can be adjusted to suite the incident, ie lane closures, reduced speeds, and the correct reason; ACCIDENT / OBSTRUCTION / STRANDED VEH etc.
These cameras are recording all the time, so sometimes they pick up the incident actually happening, the footage can then be used by the police as evidence.
99% of these camera can be seen by the general public, just go to the TRAFFIC ENGLAND website,http://www.trafficengland.com/ click on the bit that you want to look at, then switch on the CCTV button. If there is an injury RTC, often the camera is blanked to the outside world, so as not to cause distress etc.
The last camera that I believe the HA have some sort of input in, (& I don't know just what) are those at roadworks with a reduced, mandatory speed limit.

These are ANPR, not traffic monitoring.To find out who is entering and leaving town/village. Criminal detection.

Traffic monitoring etc for the likes of Google are done via sensors in the roadlbc said:

Being pedantic but.. I doubt very much Google have access to ANPR data.Google Maps traffic data is crowdsourced from the multitude of Android devices that are carried by people and are communicating with its servers telling them when people are stationary/moving slowly on roads, etc.
ANPR. Story in our local paper( I'd suggest scare PR tactics by police)is that when it's activated, the vehicle is tracked by local CCTV in town centre and local police advised. most town centres have this installed - great idea as it catches the illegal motorists out. That's the non criminal ones. The other side know where these cameras are and avoid them. But I'd suggest unless there's an operation to target illegals, then the reports go un heeded, as local forces are that stretched to get involved.

I've not seen these before but personally think they are a brilliant idea if they scan all number-plates without all the silly fines. If you are burgled then a quick check of the cars driving in and out of the area in a time-span in the area will provide police with a very useful list of number-plates to go and visit. Most crime committed nowadays is by low-life druggies who probably wouldn't have the sense to change the plates!

Very much so. Quite often ANPR hits are the sole lead in an investigation, and can often lead to a conviction. Fantastic bits of kit.Mk3Spitfire said:

Luckily, about five minutes after arsonists had poured huge amounts of petrol though the Mohammed family's letterbox, an automatic number plate recognition (ANPR) camera on the outskirts of town picked up a dark VW Golf driving by.
"That led us down to London and subsequently to identify Junaid [Mohammed] Miah, Sadek Miah and Habib Iqbal," said Mr Hunter.
