Troubleshooting

There is no picture at night.
• Camera is capable of seeing in extremely low-light conditions (0.1 Lux),
but it cannot see in total darkness.
It is recommended to install the camera where there is some ambient light
(for example: street lighting, starlight, moonlight, etc.) or leave a light on in
the area where the camera is installed.
No image at startup.
• When the camera is first powered on, it performs a startup check. It may
take up to 2 minutes after startup for the camera image to appear.
• Check to ensure your camera is properly connected (see 3 Connecting the
Camera) and the power adapter is plugged in.
• Connect the power adapter to a different outlet.
• Make sure power adapter is the original one provided (12V DC). Do not
use other power adapters with this product, as this will void the warranty.
No image or camera image is unclear.
• Dome cover is dirty. Clean the dome cover with a soft, slightly damp cloth.
Do not use anything other than water to clean the dome cover, as chemi-
cals such as acetone can permanently damage the plastic.
• Extension cable run may be too long (see 4.2 Extension Cables for details).
• Voltage may drop over distance and affect image quality. The power adapt-
er must be connected either at the end of the provided 60ft (18.2m) cable
or directly to the camera cable.
Image is distorted.
• Image may become unclear when camera is tilted too close to the camera
base (for example, pointed parallel to the ceiling). Tilt the camera using
DVR PTZ controls.
Image is too bright.
• Ensure your camera isn't pointed directly at a source of light (e.g. sun or
spot light).
• Check your DVR's brightness and contrast settings.
• Move your camera to a different location.
Image is too dark.
• Check your DVR's brightness and contrast settings.
