Troubleshooting
1. The Power LED and Ethernet Activity LED do not light up.
The power supply or camera might be faulty. Check that the connection to both
the power source and the terminal on the back of the camera are secure and
that you are using the provided power supply. If the camera is otherwise
functioning correctly, the LEDs might have been disabled in the configuration.
See the section of this guide on Configuration of System settings.
2. The camera can’t be accessed or access is slow

lights will damage the CMOS sensor.
5. The camera images are ‘noisy’
Often if the camera is in a low-light environment, the images can contain a lot
of noise. Try enabling Night mode and see if that improves the image quality.
Otherwise, try to use the camera in a location where there is a bit more light.
6. The camera images are of poor quality.
Make surethatyourcomputer’sdisplaypropertiesaresettoatleast 16-
bitcolor.Using16or256colorsonyourcomputerwillproduce dithering artifacts in
the image, making the image look as if it is of poor quality.
Try also adjusting the brightness, contrast, saturation, light frequency and anti-
flicker controls on the Video Settings under the Configuration menu. You may
also consider adjusting the resolution of the camera and the compression rate
to improve the image.
7. Video can’t be viewed through the web browser interface.
