Police Laser Guns work by firing a pulsed beam of light at a vehicle which then measures the time taken for it to return, this can take as little as a third of a second. The beam is very narrow, this allows the enforcement officer to be very precise in which vehicle they want to target. From a motorway bridge any vehicle in a line of traffic could be targeted.The beam fired from the gun is of a conical shape, the further away from the gun, the wider the beam.This causes great problems when fitting a Laser detector to a vehicle, as complete coverage is very difficult to achieve at short range, with only one sensor. (Auxiliary number plate sensor available separately – please contact us for details). How the enforcement officer chooses which vehicles to target. Even though the police have all the high tech equipment for measuring and recording the speeds of motorists, it is down to the officer using the equipment to choose which vehicle to target. A lot of people believe that the police are checking every vehicle as they go by, this is not the case. Guidelines state that an officer can only measure the speed of a vehicle that they believe to be exceeding the posted limit.This is often why a driver with a Laser detector fitted may see a gun or van nearby, but will not get a warning alarm as they drive by. The majority of the time they are targeting the number plate of the vehicle as this is normally vertical to the road, but any part of the vehicle could be used. Where is the best place to mount a Laser detector? Tests with Speed Enforcement teams have shown that the most effective place for mounting a single detector is low down on the front windscreen. Above 200 metres this has proved to warn every time the vehicle was targeted. (tested with a standard saloon car). If the Laser gun is targeting your number plate at less than 200 metres it is likely that a dashboard mounted LASER ALERT WILL NOT detect the signal. At 200 metres the beam of the Laser can be as little as 200 mm. Warning No LASER ALERT or associated items should be attached to, or placed near the airbag module. All wiring must be tucked away as not to interfere with any of the vehicle’s controls. Note The directors of Blackspot Interactive Ltd. sell LASER ALERT as a road safety enhancement device. Driving within the speed limits at all times and within the limitations of the road conditions and your abilities is paramount.The directors of Blackspot Interactive Ltd. take no responsibility for the use of LASER ALERT for other purposes than those stipulated. Warning Modes When picking up a signal from the front – The Front LED will stay on and Rear and Aux will toggle. From the rear – The Rear LED will stay on and Front and Aux will toggle. From the Auxiliary sensor – The Aux LED will stay on and Front and Rear will toggle.

Targetting the front windscreen r plate umbe g the n rgettin Ta 150 M 1 KM Medium Medium to long range Short Range This highlights the difficulties of short range detection.The beam is very narrow and with a single sensor it is not possible to cover both scenarios. Long Range At long range it is not possible to choose which part of the vehicle they want to target. On some Laser Guns the sight is bigger than the vehicle.Wherever the detector is fitted is it possible to trigger it. Following a vehicle being targeted At short range it is difficult to detect, but if the vehicle in front is targeted from long to medium range it is possible to detect as long as the sensor is fitted to the front windscreen. to long range Rear Detection When the vehicle is targeted from the rear, the laser signal will pass thorough the rear windscreen and trigger LASER ALERT as long as no obstructions are in the way. Dash Fixing Plate LASER ALERT Power LED Front Sensor Power Cable Magnetic Windscreen Bracket 1. Fitting LASER ALERT into your vehicle – Empty all the parts out of the box and familiarise yourself with each item. Rear Sensor Earpiece Socket 3. Routing the Power Cable – Use the supplied power lead to plug LASER ALERT into your cigar lighter socket, ensuring the power cable does not interfere with any vehicle controls or airbag modules. If you use your cigar lighter for other devices, a dual adaptor may be used or LASER ALERT can be hard wired. 2. Positioning in the vehicle – We highly recommend that LASER ALERT is positioned in the centre of the front windscreen low down, just above the dashboard. Making sure that the windscreen wipers do not obstruct the view. Power LED Front Sensor Rear Front Auxiliary 4. Operation of LASER ALERT – LASER ALERT will warn the user if they are being targeted from either the front, rear or from the auxiliary number plate sensor (available separately – please contact us for details).
