The ADT QuickConnect burglar alarm is a great way of getting a professionally installed ADT alarm installed in your home for under £100. As normal with installed alarm system there is a monthly fee for the monitoring service and maintenance and checks of the system. The fee with the ADT QuickConnect is £20.99. We had an extra 2 movement detectors added to the basic package. The stand kit included two movement detectors and one door contact for the front door. A bit of research found the best offer on the ADT QuickConnect from a website offering free extras. The installation and testing took around 3 hours and the engineer talked us through how the system is used before he left. All very reassuring.
