PIR Motion Sensor Home Surveillance Unit

Compact, discreet, and straightforward — this PIR Motion Sensor Home Surveillance Unit monitors indoor movement and alerts you to activity in any room without complex installation or wiring. The PIR (passive infrared) sensor format is the most reliable technology for indoor motion detection in home security applications. Rather than using a camera or active beam, a PIR sensor detects the infrared heat signature of moving bodies — meaning it responds to actual human or animal movement rather than shadows, light changes, or vibration that can trigger false alarms in other detection systems. Key Features PIR passive infrared motion detection → Detects the infrared heat signature of moving people and animals — more reliable for indoor use than beam or camera-based alternatives that can trigger on light changes and shadows Wide-angle PIR sensor lens → Broad detection window at the front of the unit covers a wide zone across the room from a single mounted or placed position Audible alert / chime function → Built-in speaker grille with indicator suggests an audible notification when motion is detected — useful for entry monitoring in homes, offices, retail spaces, and doorways USB powered via included cable → Draws power from any USB port, wall adapter, or power bank — no batteries, no dedicated wiring, and flexible placement anywhere within cable reach Compact upright housing → Small, unobtrusive white unit sits on a shelf, desk, or surface without drawing attention — positions naturally in any room without specialist mounting hardware No-wiring plug-and-use setup → USB power connection and sensor-ready design means the unit is operational immediately on placement — no installation, no tools, no electrician required Specifications Specification Detail Detection Type PIR — passive infrared motion sensor Power USB — cable included Alert Audible chime / speaker Housing Compact upright white unit Suitable For Indoor home security, entry monitoring, office, retail Installation No wiring — plug and place What's in the Box 1× PIR Motion Sensor Home Surveillance Unit
