Informal advice on PIR positioning

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...

    Nope, most manufactuers don't do door contacts - buy Knights or Elmdene, avoid DIY 'range filler' stuff like Honeywell contacts.   I would wire using EOL / FSL so be sure to buy contacts wit

    They are good - but will be potentially blinded by the light / triggered by heat gains from those big windows.   You definitely want to consider a corner mounted, pointed away from window, d

    Do you mean not to worry as in, "yes, add a sensor there" or don't worry as in "don't add sensor 3, it will be fine without it."

     

    Which type of worry is it?:D

    Don't add another sensor

    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
