Speed
Cameras are perhaps the most cunning form of speed
enforcement. Many motorists see them as some sort
of mysterious, scientific device. In fact, a speed
camera is nothing more than a slant radar (used
in Australia since 1962) attached to a computer
and camera. Even so, the "photo-radar"
is an incredibly efficient instant-ticket machine,
when set up in areas where the speed limit is artificially
low. |

 Gatso
Speed Camera
Queensland
has 23 movable (car-mounted) Gatso Speed Cameras. Previously,
only white Mitsubishi panel vans were used. Now, coloured
4WD's and sedans have been added. Because they are not as
noticeable?
A Speed Camera
(photo radar in the USA) must be positioned absolutely parallel
to the traffic flow. If not, the device will produce incorrect
speed readings. This is the "away" mode (pictured)
where the radar beam is angled at 20 degrees across the
road in the same direction as the traffic flow. Any vehicle
above a preset speed has the rear license plate photographed.
The "towards" mode angles the beam at 20 degrees
towards the oncoming traffic and photographs the front license
plate. The "both" directions mode can be used
to check all vehicles.Gatso Speed Cameras
are used in Queensland and Victoria. The Traffipax units
in New South Wales and South Australia work in the same
manner. Western Australian Speed Cameras are Multanovas
from Switzerland.

 Multanova
Speed Camera
The European made "photo radars" used in
Queensland, New South Wales, Victoria, South Australia
and Western Australia are very difficult to detect. To
consistently defeat the photo radar, you need an extremely
sensitive detector with good filtering of false alarms.
Many detectors (even well known brands) will warn too
late to be of any real advantage./This
is a case of "only the best will do".The
Gatso and Traffipax "photo radars" transmit
in the "K" band. The Multanova units operate
in the Australian Communications Authority approved "Ka"
Band.

* Police Radar Frequencies are allocated by the Australian
Communications and Media Authority which
is a department of the Federal Government. The currently
allocated bands are listed on the ACMA
Web Site. The Radar Speed Cameras
listed in the table on this page are known to operate in
either of these two (2) approved radar bands. All states
are free to use any band (frequency) allocated by ACMA for
speed (police) radar, including speed cameras. |
