The AJAX DoorProtect, together with the AJAX MotionProtect, is a widely chosen product within the AJAX security system. The AJAX DoorProtect is also called a door contact because it detects the opening and closing of windows and doors. The DoorProtect comes in a standard version and a Plus version, the AJAX DoorProtect Plus not only detects the position of the door, but also reacts to vibrations, and when mounted on a window it can also react to tilts. If you only want to monitor whether a door or window opens, this DoorProtect is the right choice.
AJAX DoorProtect with 1200 metres wireless range
Thanks to the AJAX Jeweller wireless protocol, all AJAX products/detectors can work wirelessly over a distance between 1000 and 2000 meters from the Hub. And with the AJAX ReX, the wireless signal is expandable to up to 35 square kilometers. No other brand of security system can bridge these distances wirelessly.
Because everything is wireless, the detectors are battery-powered. At the door contacts, the batteries last between 3 to 5 years depending on how often a door opens and closes.
The door contacts are available in white and black, so no matter what colour your interior or door is, there is always a colour that stands out the least.
The DoorProtect consists of two modules: a detector and a magnet. The set contains two magnets: the large magnet is installed at a distance of up to 2 cm, the small one up to 1 cm.
Installation and setup
Ready to use from the box: the battery is already installed, so there is no need to disassemble the detector. With just one click connected to the hub in the mobile application. It can be mounted on the SmartBracket in just a few minutes.
When to choose door security
The sooner an intruder is detected, the better of course. A door contact only triggers an alarm as soon as the door opens. It is better to detect the intruder before forcing a door or window by means of motion detection outside the house, but this is not always possible.
If, for example, you live in a terraced house and the postman brings your mail to the front door, motion detection outside the house is not possible, as the alarm would always go off every time a postman visits. In this situation, you choose to secure the door. In short: All doors that are on the public road and where people regularly come, due to lack of detection possibilities outside, you need to secure with an AJAX DoorProtect.
