Installation Tips

  • Do not face the camera toward any light sources.
  • Do not point the camera toward a glass window. Otherwise, it may result in poor image performance due to the window glare from infrared LEDs, ambient lights or status lights.
  • Do not place the camera in a shaded area and point it towards a well-lit area. Otherwise, it may result in poor image performance. For better image quality, please make sure that the lighting condition for both the camera and the captured object is the same.
  • For better image quality, it is recommended that the lens be cleaned with a soft cloth regularly.
  • Make sure the power ports are not exposed to water or moisture or blocked by dirt or other elements.
  • Do not install the camera in places where rain and snow may hit the lens directly.
  • The camera may work in extremely cold conditions as low as -25°C as it will produce heat when powered on. You may power on the camera indoors for a few minutes before installing it outdoors.
