DVR Troubleshoot

No Video From Analog or HDCVI Camera

1. I connect the camera to the device and there is no video output. If there is no video then test your power supply or try another power supply. Solution: replace the power supply.

2. If there is no video then test your coaxial cable and BNC connections for continuity or try another cable. Solution: replace the coaxial cable with BNC connector.

3. If there is no video then test your device(i.e. recorder) male BNC connectors by switching BNC cabel to other channels. If one works and another doesn't then your BNC ports are mis-configured. Solution: Re-configure the port to "Coaxial" in the HDCVI recorder (main menu*>Setting*>Camera*>Channel type).

4. This series device does not support the analog camera of all brands. Please make sure the device supports general standard definition analog camera, HDCVI. Solution: purchase compatible hardware.


I can not connect to the IP channel

1. I connect the camera to the device and there is no video output. If there is no video then test your power supply or try another power supply. Solution: replace the power supply.

2. If there is no video then test your Ethernet cable and RJ-45 connections for continuity or try another cable. Solution: replace the Ethernet cable with RJ-45 connections.

3. If there is no video then check if the camera is online or not by plugging only one camera in at a time and using our Config Tool to find it and configure the IP address to DHCP.

4. If you can see the camera on the Config Tool but cannot add the IP camera Check IP channel setup is right or not (such as IP address, user name, password, connection protocol, port number.).

5. If this doesn't work The camera has set the white-list (Only the specified devices can connect to the camera), and you will need to manually reset the camera. Please find your product on this site to find where the reset button is located, this requires some disassembly.

After I connected to the IP channel, there one*window output is OK, but there is no multiple*window output.

There are following possibilities:

  • Check the sub stream of the camera has been enabled or not.
  • Check the sub stream type of the camera is H.264 or not.
  • Check the device supports camera sub stream resolution or not (such as 960H, D1, HD1 and etc.).


After I connected to the IP channel, there multiple*window output is OK, but there is no one*window output.

There are following possibilities:

  • Check there is video from the IP channel or not. Please go to the main menu*>info*>System*>BPS to view bit stream real*time information.
  • Check the main stream of the camera has been enabled or not.
  • Check the main stream type of the camera is H.264 or not.
  • Check the device supports camera main stream resolution or not (such as 960H, D1, HD1 and etc.).
  • Check camera network transmission has reached the threshold or not. Please check the online user of the camera.


After I connected to the IP channel, there is no video output in the one*window or the multiple*window mode. But I can see there is bit stream

There are following possibilities:

  • Check the main stream/sub stream type of the camera is H.264 or not.
  • Check the device supports camera main stream/sub stream resolution or not (such as 1080P, 720P, 960H, D1, HD1 and etc.).
  • Check the camera setup. Please make sure It supports the products of other manufacturers.


I connect the standard definition camera to the device, there is no video output.

There are following possibilities:

  • Check the DVR supports standard definition signal or not. Only some series product supports analog standard definition signal, HDCVI signal input.
  • Check channel type is right or not. For the product supports analog standard definition camera/HD camera, you need to go to the main menu*>Setting*>Camera*>Channel type to select corresponding channel type (such as analog) and then restart the DVR. In this way, the DVR can recognize the analog standard definition.
  • Check camera power supplying, or camera data cable connection.


I can not connect to the IP camera.

There are following possibilities:

  • Check DVR supports IP channel or not. Only some series products support A/D switch function, it can switch analog channel to the IP channel to connect to the IP camera. From Setting*>Camera*>Channel Type, select the last channel to switch to the IP channel. Some series product products support IP channel extension, it supports N+N mode.
  • Check the IPC and the DVR is connected or not. Please go to the main menu*>Setting*>Camera*>Remote to search to view the IP camera is online or not. Or you can go to the main menu*>Info*>Network*>Test, you can input IP camera IP address and then click the Test button to check you can connect to the IP camera or not.
  • Check IP channel setup is right or not (such as IP address, manufacturer, port, user name, password, remote channel number and etc.).
