Cellular phone based home security system ???
We are looking for a diy home security monitoring system that when an intruder (interior and exterior) is detected it will call our/a cell phone, and when answered, we would be able to see (via remote hardwire or wireless camera monitors) and/or hear (via remote hardwire or wireless microphones) the intruder... and call a neighbor and/or the police if it looked/sounded like a real burglary.
Exterior we have some neighborhood pets and raccoons to work with, but interior is empty nester territory.
From what we understand that type of system (if possible, and not requiring a 3rd party monitor, only a separate cell phone account), would at least require a separate cell phone account with a 'sim card', and some cell phone providers do not have sim cards ?
System suggestions ?
Also, if this is not the right forum for this question, could someone suggest another thread/forum.
