Here is a close up of one of the newer semi-permanent poliscan speed cameras which no longer require a concrete pad on which to mount and level. They can be re-positioned more easily and more frequently. Those two small domes on top are new and I do not know if they involve some sort of additional sensing or communications capability.

Just googled this as I wasn't sure if it was radar or laser-based, and sure enough, it's the latter. Can folks comment on how prevalent these are, and where they're being used?

They are definitely laser based. They are extremely prevalent in MD where this photo was shot. They shoot you from the rear.

Thx for that. Based on that and what I've been reading about laser use locally, it seems that when I make the jump to jammers, it'll have to be front and rear. Cat and mouse game I suppose.

Unfortunately Poliscans are so close to the road and mounted at such extreme angles that shifters which are normally aimed straight forward or straight backward have a hard time defeating Poliscans. I've seen reports that by angling the shifter heads outwards a bit it improves the chances of success, but that it also negatively affects regular hand held laser operations. One has to rely upon GPS based warnings for most Poliscans and hope that the database is up to date. This particular camera in the photo (and its twin across the street) are brand new not in any database yet, but I've just reported it.

Really good points. It makes sense that they'd be harder to jam given what you say about how they're deployed. Gather these will be a revenue gold mine for municipalities, particularly given how mobile they are. Even if you could count on fellow Wazers to mark them or for databases to incorporate them, once they're marked it seems it'd be trivial to move them to a new spot to re-start the money train. Especially if they can put them on roads that have an abnormally low PSL, perhaps expressly for that purpose!

This is accurate but its only really recommended if you have at least a tri-head setup with the center head aligned straight. My previous vehicle was a civic with 6 LI heads in such a configuration and it jammed MD's Poliscans with ease front or back. Thanks for the new pic, was not familiar with this new setup.

Same here, I had no issues jamming Poliscans with the LI's. However, head alignment is key due to fact Poliscans encounters tend to be close in and/or off-axis.

@poolmon I've seen those portable Poliscans in Montgomery Co. before on Ridge Rd., infront of Cedar Grove Elementary. As for the domes on top, probably for wireless communication to upload data.

Great to hear you guys had some success with shifting the Poliscans with LIs.
When I get a new set of front/rear shifters, I intend to move my old LI's front duals to the rear with a slight angled outward orientation) to deal with the Poliscans.

adding extra heads should help with both, should'nt they? two facing out, two facing straight back

You are right, adding extra heads would definitely help (and be easier) but I have a hard time putting more money into this older system that I have.

Cat and mouse game it is FunkyDoc. Keep your credit cards paid up 'cause you're gonna need them.

Keep your eye on ebay for older heads, they pop up occasionally for a decent price and anything v8.5+ should be sufficient.

The nice thing about poliscans is that they are always transmitting and they spray a decent amount of IR energy out so in many cases something sensitive to lidar like ALP/TMG/LI or a V1 will pick up the poliscan scatter off other objects ahead before you pass the unit so you know to slow down before you are in the kill zone you might need to turn off the poliscan false alert filter to get maximum sensitivity to them for weak scatter alerts though. It all depends how they are positioned and aimed. If they are shooting at a steep angle across the road (up to 45 degrees) then they will be out of the standard jammer installation coverage and toed out heads would be needed, if they are more straight on then a normal jammer with a normal install might work fine.

Here is a photo of another model semi-permanent Poliscan in widespread use in MD.
It is more sophisticated than the first, with enhanced muti-lane tracking. It's upper camera body half is easily detachable from the lower base so the cameras are readily movable to other bases. Some of these they hide behind bushes where the primary purpose is to generate revenue, some they leave more exposed just to get people to slow down like in school zones. Some run 24/7/365, others are only on at specified times during weekdays. It all depends on the jurisdiction. They shoot you in the rear after passing so their beam is usually undetectable until you pass.

Where in MD are you seeing these? I’ve yet to see any where I am. This is depressing.

MD not only offers a wide array of speed cameras, but red light cameras too.
Two things to be aware of. Some intersections in the more populated areas have combo red light/speed cameras where if you speed up on yellow to avoid a RLC ticket you risk getting a speed violation instead. Some RLCs also monitor for right-turn-on red violations. If you don't come to a full stop on red before turning right it will ticket you. Also, if you do come to a full stop but do so over the painted stop line you will also get a ticket. Just this weekend while at a local ice cream shop I observed the RLC at the nearby intersection tag 5 right-turn-on red violators who will probably not even have recognized what they did until their ticket arrives within the next 14 days.

The first photo was taken in Frederick County. The second in Montgomery County. They use much smaller portable/mobil poliscans mounted on the hoods of vehicles in many highway construction zones statewide.

EDIT: Did I mention that many school buses here are equipped with automated stopped school bus passing ticketing cameras!

Personally, I'm totally cool with the school bus ticketing cam. Saw this video where a bus driver literally saved a student as a car sped past the bus on the pickup/passenger side of the bus. I mean, who would drive like that? That person's schedule matters more than this kid's life? People can suck at times.
