For a standard setup, we recommend following the instructions in the M27 & M47 installation guide found on the Support Page. A copy of the installation guide also came with your BLINDER purchase.
Image Right: Transponders blend into recesses and body work easily. They are situated level to the road and pointing straight ahead.
Diagram Below: This is a standard setup model for transponders in the M27 & M47 package from the user manual. This setup is designed for police laser guns only.
Some states in Australia also have other laser speed detector threats which require non-standard transponder setups. At least one transponder needs to point at each laser threat.
Transponder Dimensions:
Standard BLINDER Transponder Setup:
The standard setup, requires that all the transponders have an unobstructed view of the road, pointing straight ahead, mounted horizontal and parallel to the road surface and driving direction. (Please read the manual instructions in full.)
Advanced BLINDER Transponder Setup:
With the introduction of new laser speed cameras such as the PoliScan Speed by Vitronic, and the Redflex red light/speed camera, we have modified our installation instructions to account for these new laser threats. If you live in a state where these particular laser speed camera are used, you will need to include angled transponder heads.
The PoliScanspeed speed detection system can be setup to take photos and speed readings aimed at any of the four corners of your vehicle. To account for these various setups, one transponder (minimum) should be installed for each corner of the vehicle.
The most common Poliscanspeed setups are aimed at the left front of your vehicle and left rear corners. These angles should be covered for all WA vehicle installations.
Slanted Transponder Setup:
Angled Transponders:
In order to communicate with the Vitronic Poliscanspeed receiver, the BLINDER transponder needs to maintain communication within the 20m to 50m speed reading zone to be effective at blocking a speed reading.
The BLINDER transponders are completely water proof, however the CPU is not. For motorcycle installations, you will need to keep the CPU completely dry and free from moisture. For trucks and passenger vehicles it is recommended that the CPU be installed inside the passenger compartment, either under the dash, or in the console.
In order to communicate with the Vitronic Poliscan Speed receiver, a transponder needs to maintain a link within the 20m to 50m speed reading zone to be effective.
Recommended Transponder Angles:
The angles below best suit the BLINDER Transponders when confronted with a PoliScan Speed Camera setup.
Forward facing slanted transponders set to 20°
Rear facing slanted transponders set to 30°
Forward facing transponders at 0° for laser speed guns
Optional Rear facing transponders at 0° for laser speed guns
The PoliScan Speed can be setup on the side of the road or on the centre median strip and can take speed readings from behind and in front. They can also take speed readings for vehicles travelling in both directions. People relying on their old radar/laser detector will not stand a chance against these setups. This is why a laser jammer is your only defence.
Important Note: If you choose to install two separate BLINDER units in the one vehicle, Example 1 x M47 for the front of the vehicle and 1 x M27 for the rear, you will be running two separate BLINDER CPU's.
It is most important that one CPU be connected to the transponders facing forwards, and the second CPU be connected to all rear facing transponders.
The reason for this is that two BLINDER CPU's can't communicate with a single laser gun or laser speed camera at the same time.The result will be a complete lack of coverage.
There are a number of different combinations of transponder angles and locations. For ultimate coverage you would require an M47 for the front of the vehicle and an M27 or M47 for the rear of the vehicle. Angled transponder are a MUST to defeat fixed or mobile laser cameras. If the model of laser jammer you intend to buy doesn't have installation advice which includes angled transponders, buy a different model.
Anti-PoliScan Speed Transponder Locations:
For full cover you will require at least 3 x transponders and for excellent coverage 5 x transponders.
2 x transponder facing forwarded for police laser guns and at least one transponder facing 20 degrees to the left for the most common poliscanspeed setups. For ultimate coverage on single roads a right angled 20 degree transponder would also be required.
For Poliscanspeed laser speed cameras, the left and right rear facing transponder are a must. For laser gun coverage one or two rear facing transponders will give ultimate coverage.
Installation Testing:
Prior to installing your CPU, make sure that it has the latest software installed. You can locate the latest software from our website download page. You will require a USB A male to B male that you can leave connected to the CPU under the dash. This makes upgrading the software with a laptop a breeze. You can also purchase one of these from our web shop.
After installing your BLINDER system, it always pays to check that each transponder is working correctly and will pickup incoming laser hits from laser speed guns and speed cameras. For this purpose, you can purchase a laser tester from our web shop that will simulate different laser beam hits from a number of common and often used police laser guns.
Note: Safety WARNING!
Do not look directly into the BLINDER M27 / M47 transponders with the naked eye at close range when operating. You won’t see anything, but you might cause eye damage after prolonged exposure. The BLINDER M27 / M47 emits high-power infra red (IR) light, which is not visible to the human eye. This warning also applies to the Laser Tester. Never look at these devices with a magnifying lens or similar optical aid when they are powered up.
Installation Aids:
During installation, you may find that the body work or design of you vehicle doesn't offer a suitable mounting point for a transponder.
You may also find that your best pointing point is set slightly back from the lower body work hang your transponders from the bodywork to get the best possible position. This can be done with the aid of a simple bracket. There are some "make your own bracket" systems available that make this job really easy.
The examples below were made with a "make your own bracket" system available from Bunnings stores. The mounting holes work perfectly with the transponder brackets so that you don't need to drill any extra holes. The pieces hold together with a couple of heavy pop rivets and attach to the vehicle bodywork with either rivets or a few nuts and bolts. The metal parts come in various sizes and lengths.
POLISCAN SPEED - Delayed Photographsused as an Accuracy Check:
If this average speed exceeds the speed limit, the internal processing unit initiates the photo acquisition via a twin-camera system consisting of two high resolution matrix cameras. To guarantee an optimal image, the processing unit delays the triggering of the photo until the respective vehicle has approached the sensor to a defined lane dependent distance. (See below.) For every speeding offence, the vehicle is recorded with the licence plate and the driver windscreen facial area in close up. A flash is used to illuminate your face inside the darkened vehicle for identification purposes.
The precise allocation of the calculated average speed to a definite vehicle is guaranteed by the evaluation template (which is a white box overlay on the photo that should include the vehicle number plate and one vehicle wheel.) Extreme weather conditions can affect measurement range and driver identification.
The measurement beam monitors a portion of the roadway at a distance between 10 & 75m.
The speed measurement range covers a distance of 20m to 50m.
The vehicle photos are taken beginning 30m away.
Two cameras are used. One for a close up of the drivers face, the other for a vehicle & Licence plate image.
PoliScan Speed Measurement Process:
This speed camera is based on a scanning LIDAR, which is mounted in a stationary position and transmits short pulses of light out to a target. The measurement beam monitors a portion of the roadway at a distance between 10 & 75m.
The speed measurement range covers a distance of 20m to 50m. The transmitted light interacts with the target and is reflected / scattered back to the receiver of the speed camera and is used to determine the range of the target.
These measurements are carried out with a high repetition rate. The average speed is calculated for each vehicle in the surveillance area.
PoliScan Speed - Can be setup on either side of the road. Able to track traffic in both directions on both sides of the road.

Bubble Level:
The installation kit includes a bubble level that fits into the front lens of the transponder. This is used to make sure that the transponder is level which is very important for good jamming. Don't rely on your eye to level the transponders as the result will not be good enough for accurate setup. Make sure your installer gives you the bubble level to keep incase a transponder gets knocked out of position so you can double check the unit is level.
Maintenance of Transponders:
It is important to keep your tranponder lenses clean at all times. You will notice after a week or two that dirt grime and bugs will accumulate on the lens. Using soapy water, gently wipe the front face clean, making sure not to change the level or angle of the transponder.
If you have a transponder situated very close to the ground where it can get very wet, it is recommended that you put a small amount of silicone on the joint where the cable enters the transponder at the back. In rare events water could possibly enter the transponder via this route as the plastic doesn't always make a good seal with the cable. Under normal conditions, this isn't a problem.
