Wireless Motion Detector Safe SAFE38400 — movement detection sensor

The Wireless Motion Detector Safe SAFE38400 is a battery-powered movement sensor designed for integration with compatible alarm panels and smart hubs. Its primary function is to detect human motion in indoor environments and send alerts to security systems or automation platforms. The detector supports perimeter protection, room monitoring, and can trigger connected devices such as alarms, lights or notification services when movement is detected.

Advantages

This wireless motion detector offers straightforward installation due to its battery operation and wireless communication, removing the need for hardwiring. The sensor is intended for reliable presence detection in homes and small commercial premises and integrates with compatible systems to enable automated responses. Its compact design allows discreet placement on walls or corners while maintaining broad coverage for typical room sizes.

Suitable for

• Perimeter and interior security in residential properties
• Room occupancy monitoring in offices, retail or storage areas
• Triggering automated lighting or notification routines in smart home setups
• Temporary security installations where cabling is impractical

When it may not be suitable

This motion detector is optimized for indoor use and typical room environments; it may not be suitable for harsh outdoor conditions, areas with extreme temperatures, or locations exposed to heavy precipitation. Environments with constant heavy vibration, strong drafts near HVAC outlets, or direct sunlight on the sensor may reduce detection accuracy or cause false triggers.

Key specifications

• Power: battery operated (wireless)
• Detection: passive infrared motion sensing for human presence
• Installation: wall or corner mounting with compact housing
• Communication: wireless signal compatible with supported alarm panels or hubs
• Typical coverage: designed for standard room sizes (coverage angle and range depend on mounting height and environment)

How to use

Mount the detector at the manufacturer-recommended height and orientation to cover the intended area, avoiding direct exposure to windows, HVAC vents or heat sources. Insert fresh batteries according to polarity markings and pair the sensor with a compatible alarm panel or smart hub following the system's inclusion procedure. Test detection by walking through the monitored zone and verify that alerts or automation actions are received by the connected system. Replace batteries as indicated by the host system or when detection performance declines.

What to consider before purchase

• Confirm compatibility with your alarm panel or smart hub and supported wireless protocols
• Evaluate intended mounting locations for line-of-sight, heating/cooling sources and direct sunlight
• Plan for periodic battery replacement and check whether the system provides low-battery notifications

Usage recommendations

For reliable operation, install the detector at the recommended height, avoid aiming it toward windows or HVAC outlets, and test the coverage after mounting. Use it together with a compatible alarm panel or hub to enable automated responses and to receive timely alerts when movement is detected.
