Trusted Volumetric Tracking and Break-in Mitigation
The Ajax MotionProtect Jeweller is the staple wireless passive infrared (PIR) indoor motion sensor, engineered to monitor interior open areas within residences, offices, or critical commerce structures. Armed with a premium optical lens array, this hardware device monitors the environmental thermal background, immediately detecting infrared signatures matching a moving human body. Upon intrusion verification, the local microprocessor packs and fires an encrypted alert script to the central Hub in less than 0.15 seconds.
SmartDetect Signal Logic and Pet Immunity Guidelines
The device's internal framework features precise signal processing managed by the proprietary SmartDetect software algorithm. Instead of triggering blindly on any temperature spike, the sensor measures wave geometry, infrared spectrum bounds, and movement speeds. This strategy delivers full immunity against false alarms from indoor air currents, curtain swaying, or domestic pets weighing under 20 kg and standing below 50 cm. Furthermore, it embeds a digital thermal compensation loop: the software actively adjusts infrared sensitivity matrices in real time, guaranteeing consistent catch performances even if ambient room air temperatures climb near the human body's 36°C line.
Seamless Field Deployment and Radio Link Integration
Physical wall deployment is managed via the SmartBracket sliding panel, removing any needs to dismantle the enclosure box. Connection to the security grid requires a fast QR-code scan via the Ajax application. Two-way data telemetry runs on the proprietary Jeweller network, featuring automated frequency hopping against jamming tools and strong encryption to eliminate data spoofing.
