FREQUENTLY ASKED QUESTIONS
What do Radar Safety Detectors pick
up?
Radar safety detectors pick up X
band, K band, Ka Band, Ku band and Laser signals.
What is the ideal location for my
Radar Safety Detector be mounted?
Portable units are best mounted low
and within reach of the driver. Generally, the ideal location is
in a central area of your windscreen as low as possible, to avoid
obstructing your vision. Also make sure your unit is not being
obstructed by the windscreen wipers as this can reduce its effectiveness.
Concealed units are hardwired to
your car so the installation is unique to each different vehicle.
Your installer will be able to talk you through where the best
area is for your car.
What is 360° Detection?
Beltronics radar safety detectors
can pick up signals from 360˚ (front, side or behind). In
their latest tests, www.radartest.com found
that more than half of the models tested gave no warning of vehicles
approaching from behind. In this test, BEL detectors were the standout
performers.
How big are Radar Safety Detectors?
Portable units are slightly bigger
than a deck of playing cards. Concealed units are hardwired into
your car so most of the parts you will not see. The display on
a concealed unit is generally very un-obtrusive.
Why does my Radar Safety Detector
false alert sometimes?
Other devices sharing a similar
radio frequency cause false alerts. Automatic door openers and
some microwave emitting devices can cause false alerts. Beltronics
radar safety detectors are renowned for having the best filtering
on the market which will reduce the false alerts. On some units
you can even turn some or all bands on and off to reduce these
false alerts.
What is the difference between a
Radar signal and a Laser signal?
Radar and laser technologies are
radically different. Radar uses radio waves while laser transmits
a beam of invisible infrared light. A radar beam can be 30 meters
wide at typical target range. At the same distance, the laser beam
will be barely 45 centimetres wide. This pinpoint beam width is
why laser is so difficult to detect. There are also significant
differences in how the two types of speed-measuring equipment are
used by police. Radar can be used from a moving patrol car. Laser
must be used from a stationary position. For this reason, laser
is more likely to be used by police in metropolitan areas rather
than the open highway where moving radars remains the tool of choice.
I just passed a police car and my
Radar Safety Detector didn’t alert me. Why?
Not all police cars are equipped
with radars. Even passing a car equipped with radar would only
alert you if the police radar was activated.
I just passed a laser gun and my
Radar Safety Detector didn’t alert me. Why?
Laser is very difficult to detect
because of the narrow beam of light it transmits. If your radar
detector doesn’t have contact with this beam then it won’t
be aware of any threats, and won’t alert you. It’s
also possible that the police officer looked through the guns scope
but didn’t activate the laser if they didn’t think
you were speeding. It might look like they are firing at you, when
in fact they are just targeting you.
I have heard of a new radar band
that Radar Safety Detectors can’t detect. What is this band?
Radar frequencies used by law enforcement
authorities, are controlled by the Federal Communications Commission
or FCC, and not by any individual state or country. The Ka used
in New Zealand the same Ka in Australia. The same is for Laser,
where the United States Food and Drug Administration, or USFDA,
certify the use of laser guns. There are no new radar band’s
or laser wavelengths being used and if a new frequency is to be
introduced, must first be authorised by either the FCC for radar
or the USFDA for laser. When you hear someone mention this “new
band” or “radar gun”, it is likely they have
encountered a laser gun which is difficult to detect. Beltronics
radar safety detectors are designed to detect all radar and laser
currently used.
What is a Radar Detector Detector?
Until now all radar safety detectors
leaked a small IF (intermediate frequency) signal that police could
detect by using a device known as a radar-detector-detector" (RDD).
They scan for common IF emissions
given off by the radar safety detector. Early RDD’s used
VG2 Technology, which concentrated on IF emissions at 11.550 GHz,
but Radar Safety Detector manufactures soon moved their emissions
to different frequencies to eliminate its effectiveness. Along
came VG3! VG3 technology works in the same manner but scans for
multiple IF emissions. RDD’s are of no concern to drivers
in states where radar detectors are legal.
The VG2 Interceptor comes from Canada,
manufactured by a company named Techsonic Industries.

A newer device named the
Stalcar III comes from a Queensland company – Stealth
Micro Systems Pty Ltd. The Australian built Stalcar III
RDD was designed to sweep a larger spectrum and a higher
frequency than previously possible.
Several radar safety detector
manufacturers moved their oscillators outside of the range
detected by the Stalcar III. The RDD manufacturers therefore
redesigned them to sweep even larger bands and they were
detected. The Stalcar III can not detect a radar safety
detector that is not powered up. They also cannot detect
a radar safety detector with no traceable emissions. The
new BEL XR is the first radar safety detector to have no
traceable emissions and therefore be undetectable to the
Stalcar III and any future RDD using the same technology.

What distance should I be able
to detect radars? Is this the same for all Radar Safety Detectors?
Depending on what type of radar
is emitting the signal, will determine what distance you will be
able to detect it from. The Kustom Falcon handheld radar gun at
full power (50mW) can be detected as far away as 7km using the
Beltronics PRO RX65. The Stalker Ka handheld radar gun at full
power (50mW) can be detected as far away as 7km using the Beltronics
PRO RX65. The Multanova/Traffipax/Gatso Camera radars only output
a weak 2.5mW but can still be detected as far away as 500m. All
radar detection is effected by environmental changes such as, humidity,
elevation, particle matter in the air, rain, etc. Reflections from
other objects such as cars and buildings can also increase or decrease
the distance of detection. Not all radar safety detectors are equal
in sensitivity. A high quality unit like a Beltronics detector
will give the earliest warning
“Performance is stunning…Long
range champion – speedzones.com”.
Consumer
Warning
Ensure you get what you pay
for. The Beltronics warranty only applies to those units sold through
an authorized Beltronics Dealer. Auction sites, unauthorized dealers
and parallel importers often carry dumped stock from North America.
Beware of these inferior units which could be counterfeit, stolen
or worse. If you have not bought your unit from a Beltronics Authorized
Dealer you do not have a manufactures warranty regardless of what
the seller tells you. Units bought from North America have a limited
warranty that is only valid within North America. If you have a
unit bought from someone sourcing units from North America, (traceable
through serial numbers) this does not count as a dealer warranty
as the warranty is not passed onto a second or third purchaser.
Units that do not carry any warranty from Beltronics will not be
replaced or repaired.
