This Ajax MotionProtect Outdoor is 2x times bigger than a regular sensor, you can see a video-review on it here. And that’s a sole Ajax device for outdoor applications. It is not produced inside any Ajax Kit, and thus we conclude it’s something from another league.
The Ajax MotionProtect Outdoor is right here in our office, and we’ll tell you what it is, what it does, show it’s working principle, and also run a practical usage test along with the activation and tying it up with the Ajax Hub.

You are probably wondering why they take their MotionProtect Sensor and duplicate one on top of another. Because this is how it looks. And that’s what it basically is. Two Infrared sensors in one device. A doubled price along with that. The first thing that Ajax MotionProtected Outdoor is aimed at is to overcome the infrared sensor’s number one problem – the outdoor motion detector sensor’s accuracy, the false triggerings.
You know, trees and bushes’ leaves fluctuation, birds, pets, and similar. There is also such a problem occurring as objects in sight are getting sun-irradiated, and that causes the infrared sensor to react to an irritant, because the infrared sensor mechanism is based on catching heat-emitting objects. And that is why we have two infrared sensors built in – they are working simultaneously in a hundred percent synchronization with each other.
The recommended height of sensor’s installation is about eight to one point three meters, which is approximately the stomach or chest area of an average person, so the top infrared monitors a straight line direction and the bottom one is pointed to the area of the shin and feet.
Mechanism
As a result, the mechanism looks like this – the event of alarm happens only if both sensors’ beams are simultaneously crossed by a person, and of course, the detection range is customizable via the toggle under the device's back cover. Now enough of theory – pure facts. 2x infrared sensors, 3x anti-masking sensors to recognize external attempts to block the view of the detector.
The Ajax MotionProtect Outdoor detection distance ranges a 3 to 15 meters and is fully adjustable with the toggle in frames of this range. The device is IP54-rated, meaning rain and dust-tight. The operational humidity parameter reaches up a 100% due to a sensor type, and that’s what makes a difference – this guy operates with an incredible accuracy even in a high-humidity environments and withstands temperatures from -25 ºС or -13 ºF. to +60 ºС or a 140 ºF., thus it is suitable for either low and both high-temperatures regions. The range of signal transmission reaches up to 1,700 meters in an open area, owing to Ajax Jeweller's radiotechnology, and can be extended with the Ajax Rax extender device.
The device’s detection feature is immune to animals up to 80 cm or 2.6 feet high. The sensor is protected against harmful actions like masking and everything vandalism-related, and also guarantees an ingress protection. As with all of the rest, Ajax Sensors – the ping frequency parameter makes up a 12 to 300 seconds. Regarding the alarm signal transmission, that happens in 0.15 milliseconds.
Of course, in stock there’s also a tampering alarm and an Ajax-common smart bracket. The built-in battery life here is equal to 5 years. If we are talking specifically about how the device protects you and your property, then we talk about a 3-step algorithm.
Working Algorithm
At first, it checks whether both infrared sensors are witnessing the movement, and if that’s happening simultaneously, we get a first emergency sign. Next, data is getting analyzed by the SmartDetect algorithm, made with the allowance of outdoor interferences – here, those waveforms are getting compared and matched to each other. That’s a 2nd sign. 3rd – LISA.
Live Intelligent Spectrum Analysis that initiates a comparison of signals’ frequency components. As an output, the third and final sign. And all that happens in milliseconds before delivering a notification.
Activation / Practical Usage Test
Conclusion
Counting and summing up all the device characteristics – the conclusion suggests itself. Ajax has done an amazing job implementing 2 infrared detectors, 3 anti-masking sensors, a 3-step algorithm for threat recognition, anti-humidity, along with operating in low and high temperatures, a great communication transmission area size, an extremely fast alarm signal transfer, and a 5-year battery lifelong on top of that.
