FAQ
Q
I cannot see video from my camera at the DVR (NVR or hDVR). What can I do to restore the
video?
A
Resolution of Loss of Video problems can be specific to the camera model, the location where it is installed, and the
configuration. However, many common problems can be isolated by doing the following:
—
For IP cameras, test the network connectivity to the device using your (manufacturer specific) IP camera network utility
or with a ping command. Do all the cameras on your network respond?
If
YES,
the LAN and power to the camera is probably OK.
If
NO,
check the LAN cable, Ethernet signal, and power at the camera. If faulty, correct the problem and recheck the
video streaming.
—
Reset the camera.
—
Check the camera lens for blockages, dirt, etc. and clean if needed.
—
For cameras that have an analog video output (BNC adapter), connect a portable monitor to the camera to verify that it
is producing a good video signal. If the video signal is NOT good, the camera may need to be replaced.
Q
Everything is hooked up and working, but the video that is recorded is jerky and not
smooth. Is there something wrong with my system?
A
Smoothness of recorded video is dependent upon several factors including compression level, capture size, and the
maximum frame rate of your recorder. Most NVR/hDVRs record at frame rates of 30, 90, or 120 frames per second (fps).
The frame rate of your NVR/hDVR is divided between each channel being recorded. For example, a 90 fps DVR recording
4 channels will record 22 fps per channel, which will appear very smooth. A 120 fps NVR/hDVR recording 9 channels will
record 13 fps, which will appear less smooth and fluid, particularly when compared to a TV broadcast at 29.97 fps. If there
are irregular gaps in the video, or a momentary loss of video, there could be problems in the system. Call DIGIOP® Support at

Q
Why can’t I get a good picture from one of my cameras? The camera’s power light is blinking
or flickering.
A
This is usually a symptom of low voltage at the camera. You may have a cable run that is too long, a defective cable, or an
insufficient power supply. Try using a better quality cable, or plug the power adapter directly into the camera to bypass the
cable all together.
Q
I installed the cables to my analog video equipment, but the power plug won’t fit into the
camera or the power adapter:
A
Chances are you’ve run the cable backwards. Only one end of the camera cables supplied by your supplier will fit the camera,
while only the other end will fit the power adapter. The cable will need to be pulled, and run the other direction.
