Section 6 - Troubleshooting
• Do not install this camera next to or in front of an air conditioner outlet or vent.
• Do not install this camera close to wireless devices with high frequencies as the PIR is easily affected by RF radiation.
• The PIR functions at best when detecting lateral movements. Radial movements cannot be detected as well as lateral movements.
• Do not install this camera directly under an extreme bright light. The PIR cannot fully suppress a bright white light.
• Any movements from an object with a normal body temperature, like humans or animals, can be detected. To avoid any malfunctions, install
this camera at the proper height.
• To avoid any malfunctions, install this camera in an environment with an average temperature of 25°C. Only within a distance of 2.5 meters
can smaller movements of an object, with the average adult human's height, be detected. Between a distance of 2.5 and 5 meters, a larger
movement of an object is required for detection.
• Install this camera on a firm, static, anti-shock surface.
