To make the PIR motion sensor work more precisely and reduce its false alerts, you need to install your Reolink battery-powered cameras correctly referring to the following two aspects.
Applies to: Battery-powered cameras.
Viewing Field of Cameras & Detecting Field of PIR Motion Sensors
Tip 1: Install cameras according to their viewing field
1. The viewing angle of Reolink Argus series cameras and Reolink Go is diagonal 130° and horizontal 110° vertical while the one of Reolink Keen is horizontal 355°, vertical 90°. Please make sure that the monitoring area is well within its field of view.
2. The ideal viewing distance is 2-10 meters (7ft — 33ft), within which people will be recognized. To achieve a better viewing experience, it's advised not to place the camera too far away or too high (suggested mounting height: 2-3 meters) from the designated monitoring area.
Tip 2: Install cameras according to the detecting field of the PIR motion sensor
1. The detecting distance of PIR motion sensors is 9 meters, and the detecting angle is 120˚ horizontally. Motions out of this range can’t be detected.
2. Our PIR motion sensor is more sensitive to side-to-side movement than movement heading straight toward the camera.
For example, when a person moves straight toward the camera (shown below), the PIR motion sensor will be less sensitive to the movement.
Note: To make the camera work better, mount it well within the coverage of your wireless network.
Camera Installation Dos & Don’ts
For reducing false alarms, please note that:
- Do not install the camera facing any objects with bright lights, including sunshine, bright lamp lights, etc.
- Do not place the camera too close to a place where many vehicles move frequently; 15 meters (55ft) away from the vehicle is the recommended distance based on our numerous tests.
- Stay away from the outlets, including the air conditioner vents, humidifier outlets, the heat transfer vent of projectors, etc.
- Do not install the camera facing the mirror.
- Keep the camera at least 1 meter away from any wireless devices, including Wi-Fi routers and phones to avoid wireless interference.
