Hi,

Whats the time delay for a mobile camera in a van on the motorway between shots please?

If I was in the inside lane, with a car in the outside lane, would there be enough time for me to slow down, if I was speeding, before the camera could change position to read me? The van, in this example, would be parked on a bridge over the motorway.

Thanks.

You're thinking of gatso type cameras, which I think in this case is unlikely.

This could be one of two scenarios:
ANPR - is a document check (road tax, MOT, insurance); very unlikely that speed is measured.
Lidar - is a speed check, can operate beyond 500m range. Only 1 photo is necessary, but these are usually frame grabs from an on-board video camera.

You might get lucky. You speedo might over-read a fair bit, or the vehicle on the bridge might be a parked up police patrol or ambulance.

It was a yellow transit type van, with a window in the middle of the side panel.
So from your post do I presume that it can zap three lanes at once and record multiple cars?

Thanks.

camera vans are different in each police area. the laser speed camera can obtain your speed in 1/3 of a second using 53 samples alegedly. they can obtain readings from a great distace but acpo type approved to 2000 Feet (606m)
anpr can recognise number plates in more than 1 lane.

A lidar setup can monitor multiple lanes. One camera can target only one vehicle at one time, but it is mounted on a tripod-type setup which can be panned and tilted as desired, so all an operator need to is swing the camera around a bit to target vehicles in other lanes (just like any normal camera on a tripod). Each 'ping' can be very quick, far less than 1 second, so an operator could target multiple vehicles in quick succession (even if the vehicles are in their own lanes).
