IIRC There was a case not long back where some-one had experienced a theft, increased there security, including cameras & the thieve’s came again, in through the back of the garage avoiding the camera’s..
The camera need to be a decent quality to actually give a decent shot (how many blurred photo have you seen in the news?), if there obvious the thieves may well just use hoodies/scarves and ignore it otherwise. What use is a camera in the dark…
If they want it, they’ll get it… not saying it’s not useful in try to increase the odds of a conviction/recovery and maybe putting them off in the first place, but maybe making your garage/shed more secure/alarmed might be a better option.
