Informal advice on PIR positioning


MarkJohnson

Recommended Posts

One more question...is it worth having a PIR sensor in the top left corner of the hallway (right above / next to entrance to bedroom 2), looking at the keypad (location 3), as at the moment, the only thing protecting the keypad is the door contact sensor on main door to the flat...if somebody manages to defeat it / it malfunctions, the keypad isn't guarded as it were. Is this a necessary addition or am I overloading / overdoing it?

 

Location 3, below...

Got it. I guess it's one of those less is more situations! :D

 

Out of interest, notwithstanding the wall and that it faces into the living room, wouldn't sensor 4 be able to pick up something if the door to the flat door is flung open?

Nope, it really shouldn't, but I still wouldn't worry about it. There is nothing that can be done to defeat the alarm from the keypad

and they will have to either take things from the hallway only or proceed to any room setting off the sensor anyway

So, I've decided to take my work back underground.... to stop it falling into the wrong hands
