I literally just said it solved my problem. Most casual crime is opportunistic, and cameras and lights add uncertainty to the opportunity. Most people aren't willing to chance the camera for an opportunistic score.

> People steal things from stores which have had cctv for decades.

The crime there (shoplifting) doesn't begin until they leave.

In the case of a burglary, the crime begins when they enter.

Seems to be a pretty important distinction when discussing whether knowing a person is physically present on your property alerts you to a crime in progress.

And criminals have been caught using CCTV footage for decades.
