I’ve been thinking about buying a security system for a while now, but I don’t know that much about them. How do they work?
What does the keypad do?
What are magnetic contacts?
What is a PIR? (motion detector)
I have a dog! Does that mean I can’t install a PIR?
Speaking of sensors, how are the “glassbreak” kind operated?
I already have a battery-operated smoke detector, so why would I need one installed as part of my security system? What’s the difference?
I’ve been hearing so much about these “wireless” security devices. Do they really work well, and are they easy to use? |
