• Camera is capable of seeing in extremely low light conditions (0.1
Lux), but it cannot see in total darkness. It is recommended to in-
stall 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.
• The camera may take up to 1 minute to power up after being con-
nected to the NVR. Wait 2 minutes before following steps below.
• Check to ensure your camera is properly connected (see 5 Con-
necting the Camera, page 6).
• Ensure the camera is connected to a router on the same network
as the NVR.
• If the camera is connected to the LAN, you must search your net-
work for cameras using the NVR. See your NVR's instruction man-
ual for details.
• Make sure that the cable run is within the limitations specified in 5
Connecting the Camera, page 6. All Ethernet cables must be rated
CAT5e or higher.
• If using the power adapter, connect the power adapter to a differ-
ent outlet.
• Ethernet cable may be damaged or not connected properly. Check
your cable run or try a different cable.
• Reset the camera to factory default settings. See 10 Resetting the
Camera, page 26 for details.
