15. Troubleshooting
1. The monitoring screen did not display.
Please check the following:
a.
Check if the ActiveX add-on has been installed when logging in the
monitoring page of the NVR. Set the security level to ‘Medium’ or lower in
Internet Options of the IE browser.
b. The NVR is turned on and the network is correctly connected.
c. The IP address of the NVR does not conflict with other devices in the same
subnet.
d. Check the IP address settings of the NVR and the computer. Make sure
they are on the same subnet.
2. A channel on the monitoring page cannot be displayed.
Please check the following:
a.
The IP address, the name, and the password entered on the camera
configuration page are correct. Use the ‘Test’ function to verify the
connection.
b. When the PC and the IP camera are on the same subnet, while the NVR is on
another subnet, the monitoring screen cannot be viewed from the PC.
Solve the problems by the following methods.
Method 1: Enter the IP address of the IP camera as the WAN IP on the NVR.
Method 2: Configure the router to allow internal access to the public IP
address and the mapped ports of the IP cameras.
3. The recording is not working properly.
a. Install the hard drive(s) correctly in the NVR.
b. Make sure each hard disk tray is correctly locked.
c. Check if the recording function is enabled on the Camera Configuration page
(the function is enabled by default). Make sure the IP address, the login
name, and the password of the IP camera are correct.
d. If the above items are verified to work properly while the status LED flashes
green, the hard drive may be damaged or cannot be detected. In this case,
turn off the NVR and install a new hard disk. If the problem persists, please
