A 7U cabinet in an overhead space that is difficult to access. Installation and configuration were a bit of a headache but ended up being worth it. There was a NAS in the office and they stripped 7 drives, sleds and all, out of it. I'm guessing with such an obvious endpoint for the camera storage it never occurred to anyone there was a second box. I had something like this in mind when I wired the building. It seemed…

Cutting Starlink and stripping drives from a NAS? This seems like a pretty sophisticated operation, much more so than the usual copper thieves and the like. Do you have reason to believe your shop was specifically targeted?

How else would they have been so prepared?

This is why I think someone should market a cheap SIGINT tool that collects BT/BTLE/Wi-Fi data from nearby devices. I've got this setup running on a Raspberry Pi near my front door and it collects all sorts of useful data, even from people walking by on the sidewalk, 30 feet and two walls away. At some point, I'd love to explore vehicle emissions more, too.

So the radio equivalent of Flock cameras...

Always has been. Google got sued for doing it over a decade ago with street view cars.

That is why they need WiFi info for ‘fine location’.

Their camera system isnt awful, but I would still pick Frigate over it (I have the option for both at home and have ran each). Frigate is nice in that it works with any old RTSP IP camera - many features in Unifi's NVR support only work with their own over-priced cameras. High quality PoE cameras are extremely cheap nowadays. If you connect a non-Ubiquiti branded RTSP cam to their NVR software you lose a ton of featu…

How many cameras do you have on your frigate instance? i’ve been running frigate for couple years and seemed to have hit a limit of 6 cameras. 3 of them are wireless and 3 are connected to Ethernet. Mainly adding any more seems to adversely impact detection. I suspect it was maybe because the coral TPU board was hitting its limits. So I recently switched to intel arc a380 for inference. I’m going to add more cameras…

You were definitely hitting the limitations of the coral. Fregata (a native port of Frigate to macOS) can easily handle 25+ cameras since Apple Silicon can do detections in 1-2ms, giving you 500-1000 object detection inferences per second.

Wireless cameras can also cause their own set of issues, but I can understand using them if you have to.

The world changed. Massively. Reprice everything you're benchmarking pre covid.

Yes I know, but not by 4x. You can buy a lot of real compute for $4k, not an arm box with 16 disk bays.

Reread my comment and process it.

I tend to agree with you. In my opinion, as long as the majority of their profits come from people continuing to buy the self-host devices, it is fairly unlikely they'll ever stop offering those devices. Why change a working business model? Yes, subscription models are enticing for that recurring revenue... number must go up, right? /s If a majority of your sales are not in subscription products though, I think it wo…

They can sell subscriptions to people who buy them and allow self contained as possible. For securities sake requiring off-site storage of a security system is a non-starter.

Yeah, that's also a very good point. I imagine they're going to need to support that use case indefinitely. Hence their edge/IoT line of managed switches.

That seems low for a Frigate setup with a Coral and suggests something else isn't right. Im running ~20 1080p cameras on two Corals right now. The general rule of thumb is 8-16 cameras per Coral, but it all depends on frequency Frigate is having to pass frames to the detector. Inference time per frame portion passed to the coral is about 10ms (100 detections a second), which is fast enough to cover a good number of cameras.

Worth noting most of the time the Corals sit idle in many setups, as Frigate only wakes them up if it detects motion with simpler algorithms on the CPU first. You gain capacity for a further 100 detections/sec for every Coral you add essentially. The corals are not sitting watching every single frame from every camera, which I think is a common misconception about Frigate.

It's worthwhile to spend some time with the docs - the mistake I always see made is folks passing a full fat 4k stream for detection at some silly FPS, which generally doesn't make the detection work any better and greatly increases processing costs.

If your six cameras really are generating enough events (100 a second) to saturate a coral, I'd be looking at what else I screwed up!
