Does a radar detector pick up police laser guns and laser cams?
A radar detector does detect police laser but the drawback to using a radar detector against laser traps is that by the time the radar detector goes off, the police already have a reading.   This is because the laser “signal” is an instant-on device that is fast, narrow and very precise, allowing a police laser gun to obtain a reading very quickly.  Your radar detector gives no advanced warning against police laser.  Because laser does not bounce around like radio frequencies, the chances of you detecting laser aimed at other cars ahead of you are very low to none.

What do you need to be protected against laser traps?
The most common way to guard yourself against laser traps is by the use of devices known as "laser jammers" which are illegal because they intentionally interfere with police laser guns.  However laser guns run on the license free 904nm light spectrum which is not regulated or restricted. This means other devices like Nissans adaptive cruise control system, the ALPriority and many other consumer electronics, by default, will interfere with other 904nm laser light that comes into contact with them including police laser gun light.

 Why is the ALPriority the best (and safest) option for laser defence?

• Protects Your Vehicle:  The ALPriority is a laser-based parking sensor that also runs on the 904nm light spectrum.  Laser parking helps ensure that you don’t run into other obstructions - keeps your car looking great.
• Responsible Reaction to Inteference:  When interfering with other laser systems the ALPriority automatically turns itself off after 4 or 8 seconds (user defined) - making it the most responsible device on the market as it will not continue to interfere with other laser equipment.  Driver is notified when interference with other laser systems is occurring.
• No Jamming Codes:  Does not activate jamming code in Australian police laser guns (because it is not a jammer).
