Because of the length of time for the cops to arrive AFTER the alarm is tripped (even if all of the sensors are on "instant" trigger), the burglars will have taken what they want & be long gone.
So, was there any real benefit to having the Monitoring Subscription - other than being notified by telephone by the Monitoring Center that an alarm has been triggered?
If you have another vendor's cameras, you might have a useable view that will assist in identifying the burglars.
But, again, was the Monitoring Subscription really that useful?
