- Radar Equipment - Radar Speed guns
- Laser Speed Equipment- Laser Speed Guns eg Prolaser 2 /3 Ultralyte 20-20 and Photo Laser which is an automatic
laser speed gun unit linked to a digital camera.
- Distance over time measuring Equipment.(fixed distance over variable time)These would also include camera supported
units eg Truvelo Combi
- Distance over time measuring Equipment.(variable distance/variable time) eg Vascar
Radar detectors have been declared legal for use in countries like the UK and the US with the exception of two states. In South
Africa some legal sources say using a laser detector is illegal (it might defeat the ends of justice) but owning one and selling
is not and there is no recorded instance of a motorist being successfully prosecuted for using such a device. New Zealand allows
the use of them, as police involved in traffic work believe that radar & laser detectors slow drivers down. We are marketing radar
and laser detectors as we believe that radar/laser detectors are a necessity to reduce the risk of a speeding ticket with today's
ever stricter speed-policing. These Radar/Laser Detector units allow drivers to concentrate more on driving safely instead of
constantly watching the speedometer.
Independent Research has shown that Radar Detector users have 24% fewer accidents and drive a further 40942 miles between
accidents, through increased awareness (research undertaken by MORI in the UK). Click here to view article.
Radar/Laser detectors can assist you in detecting the presence of Laser and Radar (signals)
Not all police cars have radar or laser guns.
ICASA who is the communication authority in SA allows other uses on radar bands used by police. Most commonly this is
found on X band (10.525 GHz) and it is called a false alert. Some common false alerts are caused by automatic door
openers, burglar alarms, terrestrial microwave towers. Poorly made radar detectors in other cars can also cause your
detector to false alert. No radar detector is completely "false alert" proof.
There are approximately 300 laser guns in use. (2002)
Officers, by law, must establish a "visual tracking history" of your car. This means they must be able
to identify the make and model of the vehicle before assessing speed with a radar or laser gun. According
to guidelines with Radar your speed has to be recorded within a range of 600m and with Laser within 400m.
Different radar guns transmit at different output powers usually from 5-50 mW. If you are standing 30 metres
away from a friend and they whisper, you can't hear them. If they shout, you can. In other words, your friend
is transmitting at two different output powers. Radar range is adversely effected by humidity, elevation,
particulate matter in the air, rain, and snow.
Laser is increasingly used in metropolitan areas as it can pinpoint one vehicle in a group of traffic while
radar guns can not. At 200 metres, the laser guns 904 nanometer, infrared beam is only 40 cm wide and does not
scatter (bounce off objects like radar). If your laser detectors receiver is out of this 40 cm beam width,
chances are it will not alert to laser's use. If the laser gun were pointed directly at your detector, it
would alert. The chances of getting any advanced warning of laser being aimed at the car in front of you are
slim. Advanced High quality Remote Laser Diffusers like the Blinder Xtreme Series are very effective in
detection of Laser as they are mounted inside the target area.
For radar, the claims are valid. The letters in RADAR stand for Radio Detection And Ranging meaning a
radar transmission is very similar to your favourite radio station. Radio waves bounce off metal signs,
the truck in front of you, buildings, and other reflective objects. Although radar detectors have only a
front facing radar antenna (with the exception of the dash mounted Valentine One which has a front and
rear facing antenna), a radar transmission from behind you will most likely bounce into your radar
detector's front facing antenna. Laser is another issue by it's very directional and highly collimated,
monochromatic nature. If the detector were outside of the vehicle, most detectors will alert to laser
from the front or rear. Rear alerts are hampered by the attenuation of the glass in the rear window.
Side laser alerts are rare , and laser can't acquire your speed to the side.
Find a supermarket with an automatic door opener and drive toward it with your detector on.
The automatic door opener should make your radar detector alert.
VASCAR stands for Visual Average Speed Computer And Recorder and is a timing device that times your
vehicle from one predetermined point to another. It is like a stop watch and puts out no signal. No radar detector can warn you of VASCAR.
Photo camera tickets also known as Truvelo Combi in South Africa is an automated system with a camera
linked to a cable on the road or below the surface of the tarmac. These are very common in South Africa.
These do not make use of Laser nor radar and cannot be detected with a laser/radar detector.
Drivers have tried everything to foil radar gun from fish depth finders, to neon lights, to tin foil on hubcaps.
None of these home remedies work. There is only one way to fool a radar gun and that is by disrupting the "Doppler Shift" of the return signal.
Frontal performance of dash and remote detectors is almost identical. However, rear reception with a dash
model is superior to that of a remote. Some remotes offer a rear receiver. Remotes can't be seen. Yearly,
1 in 5 dash models are stolen. Remotes are always a good option although inevitably are more expensive to
buy and require a professional installation.
