Troubleshooting

There is no picture at night.
• Camera is capable of seeing in extremely low light conditions (0.02 Lux),
but it cannot see in total darkness. It is recommended to install the camera
where there is some ambient light (e.g. street lighting, starlight, moonlight,
etc.) or leave a light on in the area where the camera is installed.
No image at startup.
• Check to ensure your camera is properly connected (see 4 Connecting the
Camera, page 4) and the power adapter is plugged in.
• Connect the power adapter to a different outlet.
• Make sure power adapter is the original one provided. 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 5.2 Extension Cables, page 6 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 100ft cable or di-
rectly to the 3ft cable.
Image is distorted.
• Image may become unclear when camera is tilted too close to the camera
base (e.g. pointed parallel to the ceiling). Tilt the camera using DVR PTZ
controls.
PTZ controls are not working or are not working properly.
• RS485 wires not connected or connected using wrong polarity. Ensure the
red wire is connected to the + RS485 port and the black wire is connected
to the - RS485 port.
• Not enough of RS485 wire is exposed to make proper connection. Use a
wire stripper (not included) to strip off some of the wire insulation.
• Extension cables may be damaged or are not connected properly. Check
your extension cable run.
• PTZ protocol details are not configured in DVR. See your DVR instruction
manual for details.
