Surely impossible to "jam"?
It just computes the time taken to break 2 separate beams. You can't send back a "confusing" signal as you would have to zero laser reflection to prevent the beam from appearing from being broken.
Time for "SuperVeil"??

Thats how I under stand it, it just calculating the time from when you break the first beam to the second. That would render a jammer useless, unless you happened to have heads mounted on the side of your car.......or maybe a full veil paintjob.Originally Posted by charles charlie charles
I think "a deer ran infront of me and I swerved to avoid it" is a good countermeasure
Is there anyway of tricking into thinking that one of the beams has not been broken? All it would take would be fooling one of the beams in order to render it useless (if it only uses two beams.
I can see a device in the near future if this is wide spread, that let;s you see laser and use safely during normal driving.
IR light is visable on digital cameras when you use the night shot.
It does work with laser. It uses two laser beams 40cm apart with independant pulse frecuencies each. Calcluates the time it takes for the vehicle to break the beams, and then double checks with the time it takees to un-break the beams. A third laser beam, calculates the distance of the vehicle to the device, therefore knowing in what lane the vehicle is on the road. The autovelox 104 is an old version, the modern one being the 105SE with digital cameras. It shoots two digital photos with its two dig cameras, one close up of the car and licence plate, and one wide angle. Can control several lanes. It can be used on a tripod as the pic shows, or on the backseat of a police car pointin out through the rear-side window, or set up permanently on the side of the road on a cabin.
The 104 model has a flaw in that the comunication between the laser device and the control unit the LOE operates was done via RF, and therefore it could be detected by using a RF recieved tuned to its frecuency. The new 105SE is through cables so the 105 cannot be detected.
Jamming it could be posible since its a very twictchy device. Answering 1919's quiestion, its not a favorite of the LEO's since the device takes a long time to set up right, compared to a Multanova tripod for example. Its very sensitive, if there is any fog or rain it won't work, etc. And also cannot be hooked up to the cars batery, and its battery life is not too long, some LEO's complain that it does not hold up a day's work (105SE).
This is the biggest menace to drivers I can think of. For example I just saw one on Monday, it was being set up on a tripod behind a highway barrier/sign, it was completely hidden from view of the drivers (you could only see once you had overpassed it which was too late), its undetectable, un-jammable, and it can be setup anywere. Any driver that was driving on either lane that day had absolutely no chance.
It is my opinion that this device can be jammed if its hit by strong IR light, since its so sensitive, but never got a chance try try anything agisnt it, though was close at one time.
Doesn't a jammer at the side of a car works Carlos? Since it works with laser.
I think it only uses the laser to "break" the beam eh? If you could just use a solid beam of this stuff on either side you'd be in business
Hmm..yea what I was thinking. Are these thing set at a predefined height? Or maybe have something on the side of the car with a sort of wide lens that would cover a wide plane. Just something that would confuse the thing into thinking the beam has not been broken.I think it only uses the laser to "break" the beam eh?

Thats exactly was I was thinking Harold, we almost got a chance to put this to the test but unfortunately weren't able to in the end.
We have found out that the autovelox works on the same waveleght as the LIDAR. The only problem is for the jammer to go off and not think its a false signal so I was going to use an old LE-850 which I can voluntarily make it go off with a simple TV remote and see if its IF would "blind" the Autovelox.
Maybe a simple LED system would be enough to blind it, since it doesn't need to match the pulse freq or anything because as you say, its not LIDAR based. LED could maybe even allow for it to be permanently "ON" emiting light so that the systemn would not need to detect teh Autovelox to work.I think it only uses the laser to "break" the beam eh?
