Hi I am looking to install a burglar alarm but I am having difficulty finding what I need. I Have a cat but I guess the pet friendly pirs are a bit unreliable so perimeter on ground floor. So heres what I need 3 x door contacts 2 x PIRs Siren control panel. I want to control it with an app on my smartphone. I have most of the wires in place so want a hard wired or hybrid alarm. I would consider a camera but am wary of it being hacked. Any advise on a suitable system? lee cee dee
