Installation
- Wall materials must have sufficient strength and stability to ensure that screws are securely fastened and the overall structure is sturdy.
- Screws should be fastened in locations that avoid electrical wiring, water pipes, and other elements within the wall to prevent damage to the wall structure or safety hazards.
Ceiling Mount
- Do not install the device close to the entrance or exit. If necessary, ensure there are no other doors nearby or that the door remains open most of the time.
- The optimal operating temperature range is between 15°C and 32°C. Keep the device away from heat sources, cold sources, and areas with strong airflow such as windows, vents, fans, and air conditioners.
- Avoid installing the device directly against a wall. Ensure there is at least 45 cm of clearance between the device and the wall.
- Make sure the sensor is facing straight down and parallel to the ceiling.
- The maximum detection ranges at different heights when environment
temperature is 20°C:
Installation Height (m) Passage Detection Width (m) 2.2 2 2.3 2.2 2.7 2.5 3.0 2.8 The higher the ambient temperature, the smaller the detection range becomes.
Step 1: Take off the back cover of the device, and drill 2 holes in the ceiling according to the mounting holes on the cover.
Step 2: Fix the wall plugs into the ceiling, then fix the back cover to wall plugs with screws. Note the pedestrian direction arrow on the cover when fixing.
Step 3: Install the device back to the cover.

Wall Mount
- Avoid facing the device to a transparent plate (like glass) as the PIR will detect through it.
- The best installation height is 1.2~1.3m above the ground.
- The passage detection width for wall mounting should not exceed 2.3 m.
- The optimal operating temperature range is between 15°C and 32°C, so keep the device away from heat sources, cold sources, and the areas where airflow varies greatly like areas with windows, vents, fans, and air conditioners.
- When the ambient temperature is between 29°C and 32°C, it is recommended to install the device on the wall rather than on the ceiling.
Step 1: Take off the back cover of the device, then fix the wall plugs to the wall according to the device mounting holes on the cover.
Step 2: Secure the back cover to the wall plugs using screws. Please note the pedestrian direction arrow on the cover during installation.
Step 3: Install the device back to the cover.

Factors Affecting Accuracy
- If two or more people pass side by side, they may be counted as one individual.
- Two or more people within the distance of 50cm will be counted as one person or reversed.
- Animals or other moving objects will be counted if they are close to the device.
- Walking extremely slowly may cause the data not to be recorded.
- Locations with sudden temperature changes exceeding 5°C can easily result in counting errors.
