Ajax - Wireless outdoor motion detector with anti-masking and pet immunity (MotionProtect Outdoor)

MotionProtect Outdoor is a wireless outdoor motion detector for the Ajax security system. The detector communicates with the hub via protected Jeweller radio protocol at a distance up to 1,700 meters in the line of sight. MotionProtect Outdoor features protection against blocking the detector view (anti-masking system) and triggering by pets (pet immunity). The motion detection distance is adjustable: from 3 up to 15 meters.

MotionProtect Outdoor can operate both on pre-installed batteries or use an external power supply. Depending on the detector settings, the batteries’ life is up to 5 years.

The first line of defence for home and business

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 anti-masking system

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

We have developed the Jeweller radio protocol 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.

• Two-way communication at a distance of up to1,700 meters
• Alarms delivered in0.15 seconds
• Adjustable ping interval from12 seconds

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.

• Resists the heat up to +60°С
• Withstands the cold up to −25°С
• Protected from dust and water jets IP55
• Up to 5 years of battery life

Installation without brain teasers

To connect MotionProtect Outdoor to the hub, simply scan the QR code with your smartphone’s camera. Thanks to SmartBracket mounting plate, the device can be installed without disassembling the body. Use the Ajax app to test and configure the detector.

At the same time, the installation of outdoor detectors is a professional task. It requires landscape assessment, understanding of potential break-in points, and prediction of possible problems with interference. To ensure that MotionProtect Outdoor works efficiently and to avoid false alarms, please contact a qualified engineer.
