Two-stage algorithm for false alarm prevention
The street is always full of action: the wind sways leaves and bushes warmed by the sun, animals and birds move, various insects rest on the detector case. This diversity of flora and fauna creates constant impediments that make it difficult for outdoor motion detectors to spot the real threat: humans. We solved this problem at both the software and hardware levels by implementing two PIR sensors and developing a unique two-stage algorithm for signal analysis, LISA.
Correlational analysis
Every time MotionProtect Outdoor detects movement, LISA analyzes and compares the shapes of the signals coming from the two sensors in real time. If they are similar, the alarm is triggered.
Spectral analysis
When both sensors detect motion but correlational analysis does not identify sufficient similarities, LISA compares the frequency components in the signals from both sensors.
Intelligent anti-masking system
An external detector is an easy target. During the day, when the system is disarmed, intruders can block the view or damage the sensors, to gain an advantage in night-time intrusions. To prevent cases of sabotage, we have equipped MotionProtect Outdoor with an anti-tamper button and an advanced anti-masking system that can remain active 24 hours a day. MotionProtect Outdoor's anti-masking system automatically calibrates by analyzing the surrounding area when mounting the device on the SmartBracket. Then, if an obstacle appears in the field of vision of the anti-masking sensors or if they are painted, the detector quickly notices the sabotage and raises the alarm. Additionally, even light tampering is recorded, such as when someone tries to dismantle the detector from the SmartBracket.
Guaranteed alarm communication
We have developed the Jeweler radio protocol to ensure uninterrupted operation of all devices within the security system. Jeweler provides two-way communication between the hub and MotionProtect Outdoor at a distance of up to 1,700 meters and provides alarms in less than 0.15 seconds. The radio protocol uses framing to synchronize communication of connected devices, authentication to eliminate forgery, and encryption to protect against data leaks. Additionally, Jeweler is energy efficient and allows detectors to run for years on pre-installed batteries.
Resists high and low temperatures
Ajax security systems protect users in all climate zones, from South Africa to Greenland. Hot or cold, snow or rain: MotionProtect Outdoor is ready for any climate. The outdoor detector works for up to 5 years with pre-installed batteries. Furthermore, to increase autonomy and simplify maintenance in extreme conditions, we have provided the possibility of using external power.
Easy installation
To connect MotionProtect Outdoor to the hub, simply scan the QR code with your smartphone camera. Thanks to the SmartBracket mounting plate, the device can be installed without dismantling the case. Use the Ajax app to test and configure the detector. At the same time, however, installing external detectors is a professional task. It requires an assessment of the landscape, understanding potential break-in points and anticipating possible interference issues.
