FAQ
Q1� What should I do if the NVR cannot find the camera?
Q2. Try the following solutions:
− The camera needs a period to start. Please wait about 120s after
the camera is connected to the PoE port of the NVR through the
Ethernet cable.
− Ensure the camera is connected to the PoE port of the NVR
properly.
Navigate to Configuration > Network Configuration > PoE
Configuration to check the port status of the NVR. If the icon of
the port status is gray and the output power is 0.0W, it indicates
that the camera connection is abnormal or no power is supplied to
the camera. Please re-plug or replace the Ethernet cable.
− If the problem persists, please contact Tenda technical support.
Q2� What should I do if the GUI preview is normal, but no recordings
during playback?
A2. Enter the Live View page to view whether a recording icon is
displayed in the upper right corner of the channel.
If no recording icon is displayed in the upper right corner of the
channel, try the following solutions:
− If the HDD is not installed inside the NVR, please install it first.
− Navigate to Configuration > Storage > HDD to check whether
the HDD is normal. If the status of the HDD is abnormal, please
shut down the NVR first, then remove the cover and unplug and re-
plug the HDD. If the problem persists, please format or replace the
HDD.
− Navigate to Configuration > Storage > Schedule to check that
the recording function is enabled, and the recording mode and time
are set correctly.
If a recording icon is displayed in the upper right corner of the
channel, please try the following solutions:
− Navigate to Configuration > System > Time to ensure that the
system time of the NVR is accurate.
− Navigate to Configuration > Storage > HDD to check whether
the HDD space is full. By default, the Overwrite function is
enabled. If the HDD space is full, the oldest recording files will be
overwritten.
