Undetectable School speed cameras?

Hello,

I live in Rhode Island. Our radar usage to my knowledge is K, Ka and Laser. I have a Uniden DFR7 and recently when driving near some newly implemented School Speed Cameras, I found I couldn't detect them. I can see they're in operation because I saw a flash go off when another car when by them too fast. There wasn't any radar detection being reflected on my device which does work. Could it be that they are using TSR if not is there something else they use to detect traffic going 11 miles over the speed limit?

Thanks,
Al

Probably Multaradar which I believe the DFR7 can't detect. I suppose if it's using short enough bursts of radar your detector could ignore it if TSR is on, but I might be wrong. Try going back by with TSR disabled in your settings and see if you can grab a signal behind a rabbit.

Similar. I posted some pictures from the area. I actually had TSR disabled at the time and didnt detect them, but I'm going to try with TSR on and see what happens. I also have waze on android auto and they are there as speed traps so at least I have that protection. What radar detector detects Multaradar if any?

I was reading that the Uniden R7 detects multaradar, so maybe in the future that will be my next detector :)

The preferred detector to protect against MRCD is the Radenso Pro-M. That being said, the cameras in question look to be Gatso, see here. I’m not too familiar with Gatso, and I’m not sure whether or not the Pro-M defends well against it. I believe there are different models of the cameras and one detector might do better at detecting one model over another, but I do agree that Waze is most likely your best bet right now. The R7 doesn’t have reliable MRCD detection currently, but hopefully that will improve. MRCD & Gatso I believe are two different beasts though. Hopefully someone else will chime in with more knowledge on the subject.

Edit: found this:

“The city has hired Gatso-USA to add cameras at certain intersections and near several schools.”

We have these all over Illinois/chicago. Your best defense for these is the waze app . Second defense is a gps based radar detector that alerts to these with it's database.

The best defense against School Zone Speed Cameras is:

DO NOT SPEED IN SCHOOL ZONES!!!!!!!!! THERE ARE SIGNS ALL OVER THE PLACE!!!!!!!!!!

School Zone Ahead! Then School Zone Speed X MPH! Then the Flashing sign: School Zone (some showing your speed).

Lastly other people's children are present so how about doing the PSL and besides, what is to be gained by driving over the PSL in the 100 feet to 100 yards of a School Zone, NOTHING! Of course other then a TICKET or something worse that one would regret the rest of their life!

The best defence against these cameras is to mark it in memory of your detector or use the crowd sourced options.

Don’t rely on a radar detector to pick these up reliably.

Event the best detectors on the market will have trouble picking these up. The power is low. The frequencies are multiple and shift quickly. The spread of the radar beam is very narrow. They’re mounted up high and behind you as you pass.

You almost looking for a reflection from a vehicle in front of you. We have a lot of these and different types except for the Gatso.

For these low power modulated units, your choices are very few. There’s only 2 I would recommend.
Radenso Pro-M
Redline EX.

The R3 cant scan low enough.

The R7 is hit and miss and can’t tell the difference. It also mislabels all the low powered threats as K band 70%+ of the time. Not an ideal situation if there’s locked out k band door openers in the same location.

I personally don’t bother with trying to pick these up. If they’re not in the data base, I just mark them myself. Most states have laws that the cameras have to be well marked. Just like Illinois RLC laws. All 4 corners have to have signage that there’s a camera in place regardless of the direction of enforcement.

Just be thankful that mobile MRCD or photo Lidar hasn’t made it there yet.

The Radenso Pro M does have a setting to enable Gatso detection but I don't remember seeing any actual testing of it's performance.

Intention to speed in school zones is probably not most people's reason for wanting to be aware of these. Let's not hang the guy yet!

Not hanging but maybe over stating the Obvious, who needs to know the speed cameras are there when there is absolutely no reason to be Speeding in a School Zone and they are WELL marked!

That's not true everywhere though. I've seen plenty of school zones that aren't well marked until you are right there.

What I suspect is really going on is that the OP is finding equipment roadside that he's not being notified of. That in itself causes concern regardless of where it is until you know why. :) That seems to be where his question is coming from.

Not inconceivable it's redflex based, no detector to my knowledge can detect ALL forms of Redflex with reasonable warning, or at all in the case of what is used here locally.

This is what I found online from the area. Pawtucket RI.
That looks like a Gatso T-Series Pole Mount Cabinet and most likely contains a Gatso RT-4 inside. I've attached a few brochure PDFs from Gatson on the products.

The Radenso Pro M does have a setting to enable Gatso detection but I don't remember seeing any actual testing of it's performance.
There are some test videos showing Gatso RT-4 testing with a few different detectors that you can find online on Youtube. This one is very long and uncut, but you can find how different detectors did against it. The Radenso Pro M did very well.


For Gatso RT-3 and Gatso RT-4, I'll back what @Heywood has said, and add in a recommendation for the Radenso remote mount detector; The best detector will be the Radenso RC-M, then the Radenso Pro M, and then the Escort RedLine EX.
