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

    I mean if you really care about security you're not using wifi... you're going hard wired. Wifi can be messed up by your neighbors unintentionally and then there goes your tampering alarm. Tampering alarms are good when the system isn't fragile.

    No security installer is going to suggest wifi if someone's genuinely concerned about security.
