Wired PIR Motion Sensor Passive Infrared Detector 120° 6-10m for Home Security

This wired PIR motion sensor uses passive infrared technology to detect movement within a 120° angle and a range of 6-10 metres. Designed for wall-mounted installation, it serves as a reliable alarm relay for home security systems in households, supermarkets, schools, and banks. Operating on a 9-16VDC supply with low quiescent current, it is suited for continuous use in monitored environments. The NC (normally closed) alarm mode allows straightforward integration with existing wired alarm panels.

Features and Construction

The detector is built for stable wired communication and consistent passive infrared sensing. Its compact form and white finish suit most indoor settings.

Material and Build

The unit weighs 100g and is constructed with a standard ABS plastic housing (inferred from common practice; materials not stated in source). The wired connection ensures reliable signal transmission without wireless interference. The white colour option blends discreetly with ceilings or walls.

Size and Practical Fit

While exact dimensions are not provided, the wall-mounted design and 100g weight indicate a compact footprint suitable for corridors, entrances, and other narrow spaces. The 120° detection angle covers a broad area without requiring multiple units in smaller rooms.

Uses and Placement

This detector is intended for indoor use where motion detection and alarm triggering are needed. Its wired nature makes it a good choice for permanent installations.

Event or Professional Use

In schools and banks, the detector can monitor restricted areas or entry points. The NC relay output allows integration with central alarm panels for professional security monitoring. The 6-10m detection range covers typical corridor lengths or office entrances.

Everyday Home Use

Around the home, mount the detector in hallways, near front doors, or in garages. The 120° angle provides wide coverage, and the passive infrared sensor responds to human body heat while reducing false alarms from pets or small objects (if sensitivity is set appropriately).

Benefits and Buying Value

This detector offers practical security enhancement through simple wired integration and reliable PIR sensing. Its wide detection angle and adjustable range make it versatile.

Reuse and Low Maintenance

Once installed and wired, the detector requires minimal maintenance beyond occasional dusting. The solid-state PIR sensor has no moving parts, reducing wear. The working temperature range of -10°C to 60°C covers most indoor environments.

Why Choose This Product

For those building or expanding a wired security system, this detector provides a straightforward motion sensor with a 120° detection angle and 6-10m range. The NC alarm mode is compatible with many alarm panels. No wireless pairing or battery changes are needed, making it a low-fuss addition to a security setup.
