Jammer Type Detection now available for your SpeedLaser
Speedlaser firmwares releases v5.20 & above(1) will not only indicate when a Jammer is in operation, but will identify the type of jammer being used.
How it works: The SpeedLaser normally displays the target vehicleís speed in the HUD, but while potential jamming is being detected, the HUD will display the speed and/or "JA-n" (where "n" is the type of jammer as described below)(2). In most cases the SpeedLaser still computes the target vehicle speed, sounds the valid speed tone and displays the speed on the LCD screen on the back of the SpeedLaser. When the SpeedLaser positively detects a jammer, the SpeedLaser will latch the word "Jammern" on the back panel LCD (where "n" is the type of jammer as described below)(2). "Jammern" will remain on the LCD when the trigger is released and any known speed of the target vehicle will be displayed. Just as the speed is erased when the trigger is pulled, "Jammern" is also automatically erased rom the LCD the next time the trigger is pulled.
Stealth Mode - please note that when your SpeedLaser is in stealth mode, many jammers will not detect your SpeedLaser so the jammer will not be activated. No warning to the driver, no active jammer, no jammer indication, just a speed reading.
Suggestions for improved jammer detection
If you see in the HUD:
"JA1" - Usually not effective. Move the aim point to another part of the vehicle if necessary.
"JA2" - Limited effectiveness. Move the aim point or just remain on target for a few seconds. Watch for the
tail-tell nodedrive as the driver announces he is speeding by hitting the brakes.
"JA3" - While effective, the Stealth Mode of the Speed Laser is specifically design to defeat this type of jammer. Consider switching to stealth mode on this vehicle.
(1) How to tell what version you have
When the SpeedLaser is powered up, it will display the firmware version number at the right end of the third line. Any SpeedLaser with version v4.00 or higher can have Jam Typoe detection added at no charge for the upgrade to the law enforcement community.
Type 1 jammers generally broadcast pulses continuously at a high repetition rate; most donít even inform the driver that a LIDAR has been detected.
Type 2 jammers donít emit until they detect a LIDAR. They broadcast more powerful pulses but can only do so for a few seconds. Then they must cool down for about a minute before activating again.
Type 3 jammers attempt to lock on to the repetition rate of the incoming pulsed laser and emit bursts of high power laser pulses according to
predicted timing of received laser pulses. While very effective, the Stealth Mode of the Speed Laser is specifically design to defeat this type of jammer.
Due to poor quality of the jamming being received from the jammer, a jammer may appear to the Speedlaser as a different type than it actually is. This happens most often with a type 1 jammer being detected as a type 2.
