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.

Viewing Field of Cameras & Detecting Field of PIR Motion Sensors

Tip 1: Install cameras according to its 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 from the designated monitoring area.

 

Ideal Viewing Distance

Tip 2: Install cameras according to the detecting field of 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.

Movement Less Sensitive to PIR

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 in order to avoid wireless interference.

Finding Reolink battery-powered cam’s Optimal Motion Zone

The field of view of Reolink battery-powered camera is diagonal 130° and the PIR directing angel is horizontal 120°, please make sure the monitoring area is well within its field of view.

Our PIR motion sensor is more sensitive to side-to-side movement than movement heading straight toward the camera or away from the detecting field (horizontal 120˚) of the PIR motion sensor.

Common Errors

A common error is mounting the camera too high, and aiming it too low.

The camera works great at about nine feet above ground level with the motion sensor parallel to the ground. From this height, the camera can cover a wide visual area, as well as capture HD video of visitors’ faces.

When the camera is mounted too low, it reduces your Optimal Motion Zone. It can work if you’re only looking to detect motion in a very small area, but more often than not results in not detecting approaching visitors or capturing the top of heads when the sensors are triggered.

Don’t be afraid to mount the camera high. It will capture clear video of visitors’ faces and cover a wide visual area. You’ll be more likely to capture the events you want to know about and be notified as soon as they happen.

Note: To get the best performance of the camera, please make sure the camera is mounted well within the coverage of your wireless network.
