I found a horrible forum post! Someone had a system with some kind of old software and it was hooked up to a bunch of IP cameras, and the software only supports motion-jpeg.
Now, they need to upgrade them to HD for legal reasons, right?
but most IP cams are h264 these days...
So they decided to use USB webcams instead, because you can easily get those in HD resolutions.
But they were having trouble, because they were getting glitches and errors on USB cables over 40 feet. they'd tried 60 feet.
for comparison, the length of a USB cable is 5 meters, or 16 feet 5 inches.
So even on the generous side, they were out of spec by TWENTY FOUR FUCKING FEET
Now, there are repeaters, also known as active USB cables. They'll let you extend the cable length.
This person tried them, and they didn't help. Presumably the devices are not happy with the latency of having to go through 4 extenders
for the record, the not-batshit-insane solutions for this problem would be one of:
1. Just use modern h264 cameras, then have some software running that transcodes it to MJPEG for the old software
2. Stick a small computer (raspi?) at each USB camera, make them serve MJPEG
both of these options let you use FUCKING NETWORKS, not USB which is NOT A FUCKING NETWORK
