The wired cameras (Ubiquiti) alert me to being disconnected physically. The wifi cameras (Blink) will alert me if I lose connection for more than 30 minutes.
It is an arms race, criminals break in > you buy better locks > they get battery angle grinders and 1mm discs > you fit cameras > they use laser pointers to destroy sensors > you fit alarms ... etc.
In the UK the police are rather reactive to crimes they don't have the numbers to do the job. The focus has been on catching people who have something to lose, such as a driver's licence.
One idea I had was to build a directional detection system for signals. Track them as things pass by. A noisy jammer might be trackable so you can see it approach or leave. An antenna on each corner of the house, and a good accurate timer and you can pinpoint the signals. In theory, you might pick up on their mobile phones before they turn on the jammer then you have a fingerprinted device to track during the day when they don't have a jammer.
