Professional Infrared Motion Sensor Overview This infrared motion sensor uses advanced infrared detection and digital optical technology to reduce false alarms and missed alarms. The builtin speaker sounds when motion is detected, providing clear, immediate notification. Key benefits Reliable detection: PIR motion sensing combined with digital optical processing improves accuracy and reduces false triggers from small disturbances. Long reach: Detects movement up to 196 inches in open areas for early alerting of approaching people or animals. Wide coverage: 110 degree detection angle provides broad, allround monitoring. Adjustable installation: Includes an adjustable wall bracket for flexible placement and aiming. Simple wireless control: Two remote controls included for arming, disarming, and manual triggering. Self powered: Alarm unit runs on 4 x AA batteries; each remote uses 3 x AG13 button cell batteries included. Features and performance Detection technology: Passive infrared sensor with digital optical filtering to limit interference from ambient light and reduce false alarms. Detection range: Up to 196 inches in unobstructed areas. Detection angle: 110 degree coverage for hallway, doorway, and open space monitoring. Alarm output: Builtin speaker activates when motion is detected. Power: Alarm powered by 4 x AA batteries; remotes powered by 3 x AG13 button cell batteries included. Installation: Wall bracket allows angle adjustment for coverage and placement. Use scenarios Home perimeter monitoring: Mount near side doors, back doors, or yard entries to alert when strangers or wildlife approach the property. Pet and doorway control: Position near interior doors or exits to deter dogs or other pets from sneaking out. Small business or garage entry alert: Install above service counters, storage room doors, or garage entrances to receive immediate alerts when someone enters. Compatibility and practical notes Wireless remote controls allow simple arming and disarming from a short distance. Designed for indoor or sheltered outdoor mounting where the specified detection range can be achieved. For performance, mount at a recommended height and angle using the supplied bracket and avoid placing directly facing strong light sources. This sensor delivers continuous motion detection with straightforward installation and battery operation, suitable for home and small business monitoring needs.
