Precisely.
I have CCTV.
My neighbours were burgled not long ago.
I ramped up the CCTV and adjusted angles to cover my neighbour's (with their permission).
They came back a few months ago, did the other neighbour.
I checked on the CCTV... I have a video of a car crawling along at 2mph along the street, looking into all the houses, stopping and starting (presumably to take notes). Incredibly suspicious. I gave the footage to the police.
However, they quite obviously crawled past my first neighbour's and my house, and decided to do the next instead.
Not claiming that CCTV stops anything at all, but it discourages more than nothing at all.
Oh, and both neighbours were broken into by getting round the back and destroying the door frame.
Biting the hand that feeds IT
