Featuring advanced spatial coverage at a standard mounting height of 3.0 meters, this 24 GHz radar presence sensor offers a micro-motion/stationary detection coverage diameter of approximately 6.0 meters and a major-motion detection coverage diameter of up to 8.0 meters.
The product features an outer diameter of 43 mm and a depth of 25 mm, requiring a 35 mm cutout. Designed for recessed installation, it is also compatible with optional kits for surface mounting, wall mounting, or external installation via a universal bracket.
Interference Avoidance: Avoid installing near constantly moving objects (e.g., curtains, plants) or large reflective surfaces (e.g., metal ducts, mirrors) to minimize false alarms or unintended triggering.
Device Spacing: Maintain a minimum distance of 4 m between multiple sensors to prevent mutual interference.
Mounting: Ensure the installation surface is vibration-free. Note that radar signals can penetrate non-metallic surfaces; avoid moving objects directly behind the installation wall/ceiling.
Wiring Safety: Disconnect power before wiring. Use certified cables and ensure the circuit includes appropriate short-circuit and overload protection.
Disclaimer: Product specifications are subject to change without prior notice for improvement purposes. Please follow all wiring diagrams strictly. The manufacturer is not liable for issues caused by improper installation.
Designed for ultimate convenience and efficiency, this product supports quick on-site configuration and parameter reading using an infrared (IR) remote control. Once deployed, debugging and maintenance can be easily accomplished even without relying on a smart home platform.
