Re: Advice on sensors, please

[Crash Gordon® <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

Perimeter generally means door/window contacts...the perimeter is your =
first line of defense. Then Glassbreaks (imo), since I put them on =
Perimeter type zones, then Motion Detectors (since the bad guy is =
already in your house by then). IMO, you need a good mix of all =
three...depending on floorplan and your life style and cost/risk/value =
assessment.

Some people also include exterior perimeter - exterior motion/beams, =
fence sensors etc.
