The system works great. However, we have had issues with the sensors in the doors falling out of the frame. No way to fix since the hole was drilled "too large" for the sensor. Accidently activating an alarm is always met with a call within 3 minutes from the monitoring people checking to see if everything is OK. Cost per month is TOO EXPENSIVE. Great service and response.
