NoSpam brought next idea :
A while ago there was a discussion about USB cameras and whether they were
any use for looking into dark and dingey DIY-type places - has anyone found
anything suitable?

Well, not USB, but the Aldi/Lidl type places often advertise a fairly
small camera intended for wall mounting. We bought a B&W one a couple
of years ago for about £25. It has a built in mic, circled by IR LED's
plus IR sensitive (so dark is not a problem), intended for outdoors in
a robust metal case, had a 30m long cable and plugged into a Scart
socket of a TV. It could also be set to trigger the Scart if the scene
in the camera suddenly changed - so if someone walks near it, the TV
switched from BBC to the cameras view.
