Isn't this easily detectable?

The camera sends a ping every 30sec to the host. Missing ping: sound silent alarm with possible tampering. Missing 4 pings, let all hell break loose alarm sound.

That is how my sensors work. They work on 433/868mhz, this is open band and easy to flood. If the hub misses a ping from a sensor, the tamper protection alarm goes of.

I feel like that would cause false positives

Then again, not that many people mess with their router

If I got an alarm every time a 433 sensor didn't check in for 10 minutes, I'd never get any sleep!
