SENSORS

Two-step algorithm for false alarm prevention

• A street is always in action: the wind sways leaves and bushes warmed by the sun, animals and birds move around, various insects land on the body of the detector. This diversity of flora and fauna creates a constant barrage of noise that makes it hard for outdoor motion detectors to spot the real threat, humans. We’ve solved this problem both on software and hardware levels by implementing two PIR sensors and developing a unique two-step algorithm for signal analysis, LISA

Correlation analysis

• Whenever MotionProtect Outdoor detects motion, LISA analyses and compares signal forms from two sensors in real-time. If forms are similar, the alarm is raised

Spectral analysis

• When both sensors detect motion, but the correlational analysis doesn’t identify enough similarities, LISA compares frequency components in the signals of both sensors

Intelligent level of anti-masking

• An outdoor detector is an easy target. During the day when the system is disarmed, intruders may damage the sensors or block their view to gain an advantage in trespassing at night. To prevent the cases of sabotage, we’ve equipped MotionProtect Outdoor with a tamper button and an advanced anti-masking system that can remain active 24/7
• The anti-masking system in MotionProtect Outdoor calibrates automatically by analyzing the surrounding area when mounting the device onto SmartBracket. Then, if an obstacle appears in the field of view of anti-masking sensors or if they are painted, the detector quickly notices sabotage and raises the alarm. Moreover, a sensitive tamper is immediately activated if someone attempts to dismount the detector from SmartBracket

Guaranteed alarm delivery

• Jeweller radio protocol is  to ensure the uninterrupted operation of all devices within the security system. The Jeweller provides two-way communication between the hub and MotionProtect Outdoor at a distance of up to 1,700 meters and delivers alarms in less than 0.15 seconds. The radio protocol uses time frames to synchronize communication of connected devices, authentication to eliminate forgery, and encryption to protect against data leaks. Moreover, Jeweller is energy efficient and allows detectors to operate for years from pre-installed batteries

Ready for heat and cold

• Ajax security systems protect users in all climate zones, from South Africa to Greenland. Heat or cold, snow or rain—MotionProtect Outdoor is ready to operate in any weather. The outdoor detector works up to 5 years from pre-installed batteries. Moreover, to increase autonomy and simplify maintenance in extreme conditions, we have provisioned the option of using external power
