Does anyone know more about these devices? Some are obviously cameras, but the others are likely some radio scanning, potentially BLE, but I don’t know. Anyone know?
Dunno if you’re in America but here’s a site with a map of known flock cameras if you want to check if that one is part of the network
I do not believe it’s a flock though. I’m not even sure it’s an alpr, but it likely is.
It also is mobile, so do I bother marking it on deflock?
Edit: the main picture is not mobile, but there are variants including my other comment that are mobile.
Another similar device:
From left to right, top to bottom: 2 fixed box cameras (most likely 2 generations of ALPRs: an older (larger/yellowed: which they won’t bother removing, and instead keep for redundancy), and a newer (more capable) model), a ‘Pan Tilt Zoom (PTZ)’, and what appears to be a radar sensor (for detecting objects: possibly serving as a redundancy, during challenging weather conditions). I suspect the radar sensor got installed first (just for perimeter intrusion detection), they added the old ALPR next (to detect patterns in registered license plates); and the rest as an upgrade (including an increased field of view: through the PTZ’s movable head).
Road guy Rob has a video that came out yesterday and in it they discuss the bottom one being a radar alternative for loops in the ground for cars to change the lights.
A quick search for “traffic sensor” returns a whole class of items that all basically look like the rectangular brick in your photo. Supported by the temporary / construction look of the one in the other comment.
Construction company puts in a lane restriction or other traffic modification, plop down a traffic sensor to make sure cars are still flowing through properly.
I work for a company that makes security cameras and we also make radars as a supplement to the cameras. The purpose of the radar is to tell PTZ cameras where objects are so they can pan/rotate to the correct spot as quickly as possible.
In this case these look like fixed cameras so I don’t think it’s a radar.
I would assume, considering the climate these cameras are in that this is some kind of weather sensor.
Considering the size of it, it probably has a few features to it.
The large flat one looks like radar to me. I hadn’t heard of radar being used with PTZ cameras. But you can also use it standalone to measure traffic flow.
If it isn’t radar, it’s something with a large, flat antenna (probably a phased array). The other two options I can think of are a long-range RFID scanner or a point-to-point network connection.
Yeah it’s quite hard to tell. The shape is kinda generic so anything could be behind all that plastic!
Because of how wide and thin it is, it looks like a phased antenna array to me. It’s a way to create cheaper, performant antennas. You see this form factor with a bunch of RF applications in UHF to EHF range.
Here’s an example of a random mmWave radar board. Imagine a plastic case over this to keep out dust and rain.
