Radar Speed Monitoring Systems

Three (3) band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment: 

X band

10.525 GHz

K band

24.150 GHz

Ka band

33.400 – 36.00 GHz

Your detector detects signals in all three (3) radar bands.

VG-2

VG-2 is a “detector detector” that works by detecting low-level signals 
emitted by most radar detectors. Your detector does not emit signals that 
can be detected by VG-2, but does detect VG-2 signals and will alert you 
when a device is in use near your vehicle.

Safety Alert Traffic Warning System

FCC-approved Safety Alert transmitters emit microwave radar signals that
indicate the presence of a safety-related concern. Depending on the frequency
of the signal emitted, it can indicate a speeding emergency vehicle or train, 
or a stationary road hazard. 

Because these microwave signals are within the K band frequency, most
conventional radar detectors will detect Safety Alert signals as standard 
K band radar. Your detector, however, is designed to differentiate between
standard K band and Safety Alert signals, and give separate alerts for each.

Safety Alert technology is relatively new. Safety Alert transmitters can 
be found in limited numbers in all 50 states, but the number is growing.
Depending on your location, you may not receive these alerts regularly 
and may often encounter emergency vehicles, trains and road hazards 
without being alerted. As the number of transmitters increases, 
these alerts will become more common. 

When you receive such an alert, please watch for emergency vehicles ahead 
of you, on cross streets and behind you. If you see an emergency vehicle
approaching, please pull over to the right side of the road and allow it to pass.

LIDAR (Laser)

The correct name for the technology that most people refer to as 
laser is actually LIDAR, which stands for Light Detection and Ranging.

LIDAR operates much like radar. Its signal spreads out like a radar 
signal, though not as widely. Unlike radar, LIDAR must have a clear 
line of sight to its target vehicle throughout the entire measurement 
interval. Obstructions such as sign posts, utility poles, tree branches, 
etc., will prevent valid speed measurement.

Some common questions about LIDAR include:

Does weather have any affect on LIDAR?
Yes. Rain, snow, smoke, fog, or airborne dust particles will reduce the 
effective range of LIDAR and can, if dense enough, prevent its operation.

Can LIDAR operate through glass?
Yes. Newer LIDAR guns can obtain readings through most types of glass.
However, the laser pulse also can be received through glass to trigger 
an alarm by your detector.

Can LIDAR operate while in motion?
No. Because LIDAR operates by line of sight, the person using it cannot
drive the vehicle, aim and operate the gun all at the same time.

Is LIDAR legal to use?
Yes. It is legal in all 50 states.
