I have now on a few occasions driven past stationary fixed Lidar camera set up in back or front of police cars with no alarm given.
Should this be happening?
Is it because I don’t have rear sensors and it’s firing from behind that this happens or do I possibly have a problem.
I will purchase rear sensors if this is the case
Thanks

Are you sure it is Lidar, not radar?
Equipment connected to cars work only when operator turn it on, so it could be it was turned off.

There is no fixed laser sensors in police cars. You most likely passed a car running ALPR Scanning or Radar that is not turned on.

If it's just a police car they may not be running anything, do you have poliscan laser speed cameras in your area? If so do you have poliscan enabled in your settings? What color LED are you seeing when running?

This user is down in Australia. He's probably seeing Poliscan or some other lidar we don't see here in the states.

In Australia Poliscan's are usually placed on tripods on the side of the road. He said the devices were mounted in the back and front of the police car. I would bet its an ALPR scanner but without a photo its just a guess.

Here is an example of one of these scanners..

Below is a Poliscan Setup

Thanks for reply guys.
Yes am in Oz.
The Police have vans set up beside the roads with a camera in either back or front, maybe even both, not sure.
In I believe all cases they are Poliscan units which will take your speed either as you approach or pass them.
Not sure if they have a nap a in the car for a few hours or if they park them there and come back later
Anyway, I have had this a few times wher I get no alert and have always hoped it was just that they were not turned on yet, but don’t think so, which is why I asked if anyone else has has this happen, or is it possible my heads are on their way out

Poli's are often setup to take rear shots now, the only sure fire way is to get a rear.. You may now and then see a camera setup on a tripod, these aren't a poliscan rather a Jenoptik Traffistar S350. Sadly ALP's detection range on these cameras is rather short, everytime I ask about improvements on this the answer is "we're working on it".

Now and then I get no detection on a Poli as well, I'd suggest they are just in process of setting up.

The thing is ALP is 90% focused on US/Canada market. They don't seem really interested in expanding their business and aren't serious about other regions. Other example is they advertise their Europe CPU is effective against RIEGL guns, but unfortunately this is not true. Then you end up with a very expensive and mostly useless gadget. The Chinese are noting this.

Poliscan systems are designed to shoot you in the rear and not the front. If you have these cameras in your area you will need rear sensors. As Dragon's noted there are also other Tripod camera systems that are similar but they are very low powered and very narrow so without rear sensors where they are aiming front sensors can miss them.

Poliscan can shoot you in the Front too. In Germany you will see only Front Shooting, because they Need a Picture from the Driver, which will get the ticket.
Most times Poliscan is installed in the trunk of a car, but they can take it out and use it on a tripod, for example for better hiding or if it is not possible to park their car beside the street.

Can you clarify what you mean by police car, like a marked police car/highway patrol or a speed camera van?
If you're talking about speed camera vans then yes this has happened to me before. Last 2 times, I came past again few minutes later and the operator was covering up the camera getting ready to leave, I'm assuming the unit was off when I originally went past.
Having said that, I've seen operators sit in the back with the camera covered up using TruCam and firing at very close range where I wouldn't be surprised to see punch through on the alp (fingers crossed it didn't/doesn't)
Things very state by state, but QLD has the cameras mounted in the rear of the van, however in the past 6 to 12 months they have put these cameras in the front passenger seat. But 95% its in the rear, WA is mainly tripod mounted but they have started using vans/SUV's.
Again if you're able clarify on the police car part, we'll be able to help more

In this topic is talking about Poliscan, but if in Europe you go through a Riegl,s you will get a big ticket, because the ALP is not alerting too for it.
