DS 2

Detected by all Snooper GPS Speed Camera Detectors and Sat Nav Systems

DS2 / Speedmaster / Autovision are names for a very similar system, which is a semi-permanent type site. There are usually 3 piezo strips in the surface of the road, accompanied by a short grey post on the verge. These sites by themselves are harmless and again warning is only given using a GPS system. They require additional equipment which is usually found in a camera partnership van or unmarked car.

SPECs Average Speed Camera

Detected by all Snooper GPS Speed Camera Detectors and Sat Nav Systems

SPECs systems operate in pairs or more of cameras usually over a mile or two. The system will focus on a vehicle number plate and then as the vehicle passes subsequent cameras, the average speed is calculated based on the length of time taken to travel over a set distance. Due to the fact that they use digital recording they are always active and as they do not use radar or laser, you will need a GPS system to detect them.

Gatso Speed Cameras

Detected by all Snooper GPS Speed Camera Detectors, Sat Nav Systems and Radar Detectors

Gatso cameras are by far the most common safety cameras on todays roads, however they will be detected by all our detectors in the Snooper range. Gatso cameras are typically yellow in colour and are accompanied by a series of white lines painted on the roads surface. A Gatso camera will face the rear of a vehicle and calculates speed by emitting a constant K-Band Radar signal. When a vehicle passes through the radar faster than they should be, a photograph is taken.

Speed Curb

Detected by all Snooper GPS Speed Camera Detectors and Sat Nav Systems

The Speedcurb camera is very rare at the moment and they are also known as "Monitron" or "Tri-eye" cameras. Due to the fact that they operate with two sets of piezo strips in the road surface rather than radar or laser emissions, you will need a GPS system in order to detect them.

Laser Camera Vans

Detected by all Snooper Laser Detectors

Mobile camera vans (including safety partnership camera vans) normally have a laser device mounted within the vehicle or a device that can be mounted on a tripod outside of the vehicle. Unlike the older style radar guns the laser has to be targeted at a specific vehicle. There are a number of sites throughout the UK where these are used frequently and they are classed as 'Risk Zones' on our Enigma database.

Watchman  

Detected by all Snooper GPS Speed Camera Detectors, Sat Nav Systems and Radar Detectors

The Watchman camera is currently on trial awaiting type approval prior to a national installation programme. Like the Gatso, a constant stream of radar is emitted and speed is calculated as a vehicle passes through, triggering the camera. The difference with this camera is that it can monitor the speed of a vehicle before you pass it. There are also two types of camera built into the head unit. One is used to take an overview of the road and the other is used as a Number Plate Recognition System. You will see these cameras often accompanied by a "speed board" which displays the speed limit for that stretch of road.

Mobile Laser Guns

Detected by all Snooper Laser Detectors

These types of laser devices can be either mounted on a tripod or can be hand held. Unlike the older style radar guns which were just directed towards oncoming traffic the laser device has to be targeted at a specific vehicle to obtain a reading.

Truvelo Speed Camera

Detected by all Snooper GPS Speed Camera Detectors and Sat Nav Systems

Truvelo cameras, whilst they may look similar to the traditional Gatso device work in an entirely different way. The camera doesn't use radar or laser to determine speed, instead speed is measured through two independent sets of piezo strips in the road surface. Once the speed is calculated, a picture is taken of the front of the offending vehicle. In order to be alerted to this type of device you will need a GPS based system.

Traffic Master Camera

These are NOT speed cameras. All Snooper GPS Speed Camera Detectors, Sat Nav Systems, Radar and Laser Detectors do not detect these.

COMMON MISTAKE!
This is an AA Traffic Master monitoring system. These can very easily be confused with a SPECs system. Consequently they are not included in the Enigma database.

Peek Speed Cameras

Detected by all Snooper GPS Speed Camera Detectors and Sat Nav Systems

It is still possible to see the older style Peek cameras in use. These work by vehicles driving over three piezo strips situated in the surface of the road. This type is also accompanied by lines on the road similar to the Gatso type cameras. Please note: They can also be used as Red Light Cameras which are not included in the Enigma database.

Red Light Cameras

These are NOT speed cameras. All Snooper GPS Speed Camera Detectors, Sat Nav Systems, Radar and Laser Detectors do not detect these.

COMMON MISTAKE!
Although made by Gatso, this camera is not for speed detection, but for the jumping of red lights. This type of camera is not included in our Enigma database.

If you any concerns relating to the AURA database or wish to verify any camera positions from it, please email Snooper at cameras@snooper.eu  including the following information:

• Type of camera
• Road number or name
• A brief description of the camera location

A MEMBER OF THE AURA DATA COLLECTION TEAM WILL VISIT THE AREA WITHIN A FEW DAYS.

Please note: Your unit has certain Logic modes that can affect how the unit alerts you to camera locations. Please refer to the section in your manual that covers this to ensure that the unit was in the correct mode to pick up the camera location before contacting us.
