Re: PIR with tamper

[Crash Gordon® <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

Because the PIR can't see through tissues, boxes, balloons, etc.

1- Tamper the PIR.
2- Use and Anti-Masking PIR that sends a trouble if it can't see =
anything when in disarmed state.

I prefer using anti-masking pir's with tamper...because you could mask =
off a pir without opening it.
