Setting up mobile traps

[Philos]

Folks,

I was watching a police biker setting up a mobile speedtrap the other day, and he had to do a lot of fussing to get the camera ready to use. It took him about 10 - 15 minutes from arriving at the site. Also I have read about the requirements in vans for the operator to calibrate equipment and update records before using the camera.

Does anyone know what time it takes (typically) from the van/bike arriving on site and the operator being ready to shoot?

You’ll probably find out within the next fortnight

Going back some years (maybe 15) I knew someone who worked in traffic and periodically used the hand held speed guns as part of her role, there was a lot of pre calibration done at the Police Station where there was a pre marked point in the yard at a certain distance so the device could be calibrated to ensure it was measuring correct distance before they left the building.

She would then choose her location and measure the distance from car to the speed limit sign so for example it was a 30mph zone on one side of the pole and NSL on the other and she would measure that distance with the laser then begin checking speeds of anyone beyond that distance coming towards her, so she was checking peoples speeds whilst they were in the 30 zone approaching the NSL zone.

It's a fairly long explanation but to answer your question, once on site in those circumstances she was ready to go within 3-4 minutes without rushing.

The setup of the gun takes about 5 minutes.

The setup of those damn tripods can take forever >_>

The speedmeter is calibrated each year. The roadside checks are sometimes known as ‘calibration verification’ checks.

For handheld devices, at the nick before going out, <5 minutes.

On location, <1 minute.
