I cannot login the administration page of the NVR.

Please check if you have the administrator authority. Only administrators are allowed

to login the NVR.

5.

The live video is not clear or smooth sometimes.

a.

The image quality may be restricted and interfered by the network traffic.

b.

When there are multiple connections to the IP camera or the NVR, the image

quality will be reduced. It is recommended to allow only three simultaneous

connections to the monitoring page at maximum. For higher recording

performance, do not open too many IE browsers to view the live video.

The same IP camera may be shared by multiple NVR servers for recording at the

same time.

The alarm recording does not function.

a.

Please login the NVR and go to ‘Camera Settings’ > ‘Alarm Settings’. Make sure

the alarm recording is enabled for the IP camera.

b.

If the NVR is installed behind a router while the IP camera is not, the alarm

recording will not work.

c.

When the alarm recording is enabled, make sure the number of days that the

alarm recordings will be retained have been specified in ‘Camera Settings’ >

‘Advanced Settings’. Otherwise, the recordings may be overwritten.

7.

The estimated storage space for recording displayed on the ‘Recording

Settings’ page is different from the actual value.

This estimated value is a reference value only. The actual disk space may vary

according to the image contents, the network environment, and the performance of

the IP cameras.

8.

The E-map cannot be displayed correctly.

Please check the file format. The NVR supports E-map in JPEG only.

computer have been turned off; or add the Finder to the list of allowed programs in

the firewall.
