I been asked to monitor windows only , they don't need intruder , I assume a panel could do this
Monitor windows open and closed , send an alarm on an app or desktop to say q certian window has opened
First thing that came to mind were 24hr zones, wireless detectors
App giving an alarm and status for each one , or even outputs activating LEDs as they want it silent , perhaps a light beep will do
Any ideas appreciated
