AJAX MotionProtect Curtain
This curtain sensor can be placed on the inside of the house, and can detect movement over an area of 2.4 meters by up to 15 meters, and up to 8 meters in the position where it does not react to animals. In addition, for each detection distance, the sensitivity can also be set in 3 positions.
The mounting height of the AJAX MotionProtect Curtain is 2.40 meters from the ground.
There are many possibilities with this curtain detector thanks to its detection angle of up to 6 degrees wide but 90 degrees high. Below we give a number of examples how you can position this curtain detector.
Installation AJAX MotionProtect Curtain
The AJAX MotionProtect Curtain is a curtain detector that, like all detectors, is easy to install. An installation on a wall, for example, can be done in this way, but there are also other mounting options.
Corner mounting bracket
A corner mounting bracket is included as standard in the delivery. With this bracket you can mount the curtain detector at an angle of 90 degrees. This is an ideal mounting method for securing windows and doors on the outside of your home or business. This means that detection takes place before someone is actually inside.
What happens in case of sabotage
Suppose… That the detector is knocked off the wall before it has detected any movement, for example by approaching from an unsecured side. Then, within 0.15 seconds, the “Temper protection” will send a message to the Hub, triggering the same reaction as if a movement had been detected. In other words, an alarm signal will be given.
If within 0.15 seconds, yes that is one seventh of 1 second, or as long as blinking your eyes once, if within this time the detector is disabled for any reason, then the following happens:
The Hub (the base station of the alarm system) always asks all connected detectors every few seconds if everything is okay. If there is no response from the defective detector, the Hub knows that something is wrong, and an alarm is triggered again.
It is therefore not really convenient for unwanted visitors to tamper with the detector, as they do not benefit from this.
AJAX MotionProtect Curtain does not react to animals
When you enable the Correlation Signal Processing function, you actually turn on the animal-friendly mode. In other words: Then the detector will not give a false alarm when registering birds, cats, or dogs. After all, only unwanted people should be registered and cause an alarm.
Distinguishing animals from humans
The distinction between animals and humans is determined as follows: The detector has 2 existing sensors, both of which can detect a movement pattern. In the enabled Correlation Signal Processing mode, an alarm is transmitted to the Hub only if all 2 existing sensors detect a similar movement. This similar movement can only be caused by humans and almost not by animals because they are too light or do not have the right body temperature.
The disadvantage of activating Correlation Signal Processing is that the range of the detector within which it detects movement decreases from a maximum of 15 meters to a maximum of 8 meters in the most sensitive position.
When Enabling Correlation Signal Processing
Switching on the Correlation Signal Processing mode is always recommended for outdoor installation.
If the AJAX MotionProtect Curtain is installed indoors, and no pets are walking around in the area to be protected, it is recommended for maximum sensitivity to leave the Correlation Processing mode switched off. This gives you the fastest motion detection over the greatest possible distance from the detector.
If the Correlation Signal Processing mode is turned off, motion detection from one of the two sensors present in the detector is sufficient to generate an alarm.
