8 Troubleshooting
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, page 4) and that the camera is connected to a 12V DC
power supply.
• Connect the power supply to a different outlet.
• If you are using a longer power cable run, ensure you use the proper ca-
bling gauge for the length of your cable run. See 3.2 Power Cabling
(Professional Installations Only), page 7 for full details.
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
chemicals such as acetone can permanently damage the plastic.
• Extension cable run may be too long (see 3.1 Video Cabling (Professio-
nal Installations Only), page 5 for details).
• If you are using a longer power cable run, ensure you use the proper ca-
bling gauge for the length of your cable run. See 3.2 Power Cabling
(Professional Installations Only), page 7 for full details.
• Voltage may drop over distance and affect image quality. It is recom-
mended to connect the 12V DC power supply directly to the camera
cable.
Image is distorted.
• Image may become unclear when camera is tilted too close to the cam-
era base (for example, pointed parallel to the ceiling). Tilt the camera
using DVR PTZ controls.
