We live in a bad area and my mum's car has been vandalised a few times. I want to put some cameras on the outside of the house but they need to be very subtle or the cameras themselves are likely to be targeted (I hope to fix the cameras to a disused satellite dish which will obscure them). My plan is to connect two or maybe three USB cameras to my otherwise useless 10-year old laptop running either Windows 7 (with Internet disabled) or Linux, probably with an external HDD. Cameras with decent resolution and decent frame rates are expensive but I guess 15 FPS is adequate. I found this module without an extra lens and this module with an extra lens on AliExpress. I was thinking I could waterproof them with some insulating varnish (I already own some) although I'm a bit unsure about the lens; I don't want to accidentally get varnish in or on the lens/sensor. Does anyone recommend alternative cameras? I don't want to use really cheap ones because the images will probably be nearly useless. Maybe I could also install a motion activated infra-red floodlight but that depends on figuring a way to disguise it. Maybe it will just look like a broken floodlight and not attract unwanted attention.
