Watchman System

This system has been on the streets for a little while now. As of typing this (28/03/04) the Watchman System does not have type approval, but is going through the process of getting it so be warned. At the moment I am told the only thing you will get in the post is a very snotty letter. My advice is, don't speed past this kit.

Top round reflective lens, NPR Camera. Square bit below is the IR Illuminator for the NPR
Round lens bottom left, Flash. Bottom Right square opening is for the overview image camera.

From my understanding the system works as follows. Two cameras can be seen inside the box. One for Images and one for NPR (Number plate recognition). The overview image camera works all the time, recording 2 frames (images) per second, the NPR camera records at 18 frames per sec for 60 frames.The whole system can deal with 10,000 number plate events or 1 month of overview images or a combination of both. The data is recorded on to hard disk and is then transmitted via GSM or HSCSD. Live images can be viewed if needed.

The smart part of the Watchman system is the radar, first from the readings on my Bel it is using X Band, a no longer used band or that what we thought. The next problem is that it reads your speed as you approach, it has eyes in the back of its head you could say, so speed up to it and slow down past it and its still got your speed.

It is worth noting that after checking over twenty of these cameras on the same day, logging lat/long for a GPS device, all gave out a signal and all seamed to be working.

It covers a much greater area than a Gatso camera, and is always paired up with a speed display board or two. The display boards have their own radar heads for detecting speed.
