i went to a site close to my house today where there used to be a building. i spoke to the demolition team when it was half demolished and they gave me access to take whatever i wanted so i did.
i wanted the CCTV cameras but they were all external and it would of been a pain getting them so i didn't bother.
i went back to check it out today and the demolition crew have gone and taken the building with them. they have cleaned up ready for the builders but left a few bits and bobs behind...
i saw a cctv camera housing, examined it and saw that the front window was cracked but apart from that it was fine so i took it home.
here is a picture of it on the building before demolition (taken from street view)

the housing was MASSIVE and basic, i reckon its probably from the 80s so i didn't expect anything special inside.

i opened the housing and found a 240V to 24VAC PSU and a panasonic day/night box cam.
the camera definitely doesn't match the age of the housing so the original one probably broke and this was probably a replacement.
but anyway... now i have a nice 'new' camera in mint condition that cost me nowt
