Two-step algorithm for false alarm preventionA 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, LISACorrelation analysisWhenever MotionProtect Outdoor detects motion, LISA analyses and compares signal forms from two sensors in real-time. If forms are similar, the alarm is raisedSpectral analysisWhen both sensors detect motion, but the correlational analysis doesn’t identify enough similarities, LISA compares frequency components in the signals of both sensorsIntelligent level of anti-maskingAn 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 24/7The 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 SmartBracketGuaranteed alarm deliveryJeweller 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 batteriesReady for heat and coldAjax 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 —Classification : Electro-optical radio channel security detectorType of detector : WirelessInstallation method : Outdoors/indoorsRecommended installation height : 0.8 — 1.3 mCompatibility : Operates only with Hub, Hub Plus, Hub 2 and ReXSensing element : Two PIR sensorsAlarm signal delivery time : 0.15 sMotion detection distance : Adjustable, up to 3–15 mDetection angle : Horizontal — 90°Sensitivity : Adjustable, 3 levelsPet immunity : Weight — not relevant / Height — up to 80 cmAnti-sabotage : Grade 3 anti-masking (in compliance with EN 50131 safety standard) / Protection against forgery / Jamming detection / Tamper-resistantPower supply : Battery: 2 × CR123A batteries, 3 V, pre-installedOptional mains supply : 5–28 V DCBattery life : Up to 5 yearsCommunication range with the central unit — up to 1,700m in an open spaceTwo-way communication between devicesOperating frequencies — 868.0−868.6 MHzSelf-adjusting RF output power — up to 20 mWBlock encryption based on AES algorithmDetector polling period — 12—300 sTemperature sensor : AvailableOperating temperature range : From -25°С to 60°СPermissible humidity : Up to 95%Protection class : IP55Remote set up and testing : Dimensions : 183 × 70 × 65 mmWeight : 322 gColor : WhiteWarranty : Replacement and repair within 24 months of the date of sale.
