SPEED MONITORING TECHNOLOGIES
Radar Facts
A radar gun operates by transmitting radio waves at certain
frequencies which reflect off objects and are picked up by
the radar gun’s receiving section. When a radar beam
reflects off a moving target, a measurable frequency shift
occurs. The radar unit converts this shift into miles per hour to
determine your vehicle’s speed. Currently, the FCC (Federal
Communications Commission) permits operation of traffic
radar guns at X Band (10.500 - 10.550 GHz), K Band (24.050
- 24.250 GHz), and Ka Band (33.400 - 36.000 GHz).
NOTE: A radar detector will not alarm if an officer is not
transmitting on any one of the above radar bands.
POP ™ Mode
POP ™ Mode is a feature on some newer radar guns
operating on K and Ka bands. When the gun is in POP ™
Mode and activated, a brief burst of energy, less that 1/15
of a second, is transmitted and the vehicle’s speed is quickly
acquired. A detector without POP
™ Mode detection
capability cannot respond to this brief transmission.
Total Band Protection ™
Complete Band Coverage that detects laser, radar, VG-2
and safety radar bands.
Laser Facts
It’s well documented that many radar guns cannot reliably provide
the speed of a targeted vehicle that is traveling in a group
of vehicles. In contrast, a laser gun can target a specific vehicle
out of a line of traffic and determine its speed. The advantage
of laser over radar in terms of target identification is the result
of the laser gun’s narrow beam. A radar gun’s transmission
In Most States YES!
Laser-Radar detectors are completely legal in every state,
(with the exception of Virginia and Washington, D.C.,
which have local regulations restricting the use of radar
receivers in any vehicle), when used in automobiles or light
trucks (under 10,000 lbs.). Concerning trucks over 10,000
lbs., the Federal Highway Administration (FHWA) issued a
regulation, effective January, 1994 which prohibits radar
and laser detector use in these types of vehicles nationally.
Prior to the FHWA regulation, laws existed in the state of
New York restricting the use of radar detectors in trucks
over 18,000 lbs. and in Illinois in trucks over 26,000 lbs.
