DIY Security System.....
A) Buying a home security system like "iSmartAlarm" or "SimpliSafe".
B) Piecing together different sensor modules & hubs to make a home security system.
I'm not necessarily looking to automate my home, I'm basically just want a system to detect and alert me by smartphone when someone has entered my home (and maybe garage) without my knowledge. If possible I would like to also be able to have a camera setup (preferably indoor/outdoor) of some kind that I can access remotely. As far as the indoor camera I've had my eye on one them Armcrest Pro cameras.
Any suggestions on which route I should take?
