False alarms/ false open/close

user_4ijunn I am sorry to hear about the false alerts. I know the window sensors are very sensitive and I have had one go off when the cooler clicked on while we were out so I understand. I had to readjust where the sensor was mounted to ensure it stopped. Most of the equipment for our security services is purchased outright and is yours to keep unless you are within the 30-day return period. If you are within the 30-day return period we would be happy to look into what can be returned.  If you could send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you.
