Motion detector

Start by matching where it will be used—homes, villas, offices, or warehouses—and then review key sensing specs. Look for a detecting distance of about 12 meters and a coverage angle of 110 degrees to ensure ample area is monitored. Wireless operation at 433 MHz with up to 100 meters open-area reach helps you place the unit where wiring isn’t feasible. Power is usually 9V battery-based (battery not included), and installation height around 1.7–2.5 meters. Also check the red alarm LED and yellow low-battery indicator for easy status checks.

The most complex attribute is the wireless communication setup and its environment. A detector at 433 MHz can cover large spaces up to about 100 meters in open air, but walls, furniture, and interference can affect reach. The product also specifies anti RF interference ranges (approximately 10 MHz to 1 GHz at up to 20 V/m), which guides placement away from strong RF sources. Understanding how range, interference, and line-of-sight interact helps you place detectors for reliable alerts.

For a home setting, prioritize compact, easy installation and clear indicators, like a red alarm LED and a yellow low-battery LED. For a small business or office, consider multiple detectors to cover key corridors and entrances and plan alignment with an alarm host. The detector described is suitable for residential houses, villas, factories, markets, warehouses, and office buildings, so map your space to determine how many units you’ll need and where to position them for optimal coverage.

Maintain reliability by replacing the battery when the low-battery indicator lights yellow and inspecting the red alarm LED during tests. Operate within the specified temperature range of -10 to 50 degrees Celsius and keep humidity under 95% to avoid condensation. Install at the recommended height (1.7–2.5 meters) and ensure mounting is secure (wall or corner). If you’re integrating with an alarm system, verify it can receive the alarm signal from such wireless sensors.

Yes, you can mount this type either on a wall or hung in a corner to maximize the sensing field. Wall mounting is common for hallway protection, while corner placement can extend coverage along two walls. The outline size given (roughly 59 by 45 by 107 mm) helps you gauge space and avoid placement behind furniture or fixtures that could block the infrared sensor.

Check for clear LED indicators that show alarm status and battery level, and ensure the unit reports movement reliably to the alarm host. Look for a solid detection profile: a 12-meter range with a 110-degree angle ensures broad coverage. Wireless distance figures (up to 100 meters in open space) help you plan placement with minimal wiring. Also confirm the device uses a low-power design to extend battery life and reduce maintenance frequency.
