I should have worded this better. I meant when they are going to commit a crime, and they see a CCTV in that area, they should be able to block or break it for that one crime only and not just randomly. So that criminals are actually encouraged to plan out and be smart about their crimes or risk getting caught. Or like you said, devices to do those things. ProTech could once again be responsible for maintaining these broken/meddled with cameras, which provides them a new avenue of roleplay.
