Why do some radar detectors work and some don’t?
The current circumstances surrounding speed enforcement methods in Perth and throughout Australia are somewhat different to the circumstances in the United States where Radar Detectors are made, so even though it may be a top-performing Radar Detector in the US, it may be one of the worst performing detectors here. It all comes down to the quality of the detectors radio receiver and the software. In most speed camera scenarios, the camera is taking a photo of the front of your vehicle; this means it will measure your speed by transmitting a radar beam towards the front of your vehicle. 80% of radar detectors work in this scenario. In 1/5 scenarios, speed cameras can be setup to take a photo of the rear of your vehicle, this means the radar beam is transmitting towards the back of the car as you drive past the camera, if you are using a radar detector, because the radar beam is not transmitting directly towards your radar detectors receiver (located on the front of your car), in order f
