I connect the general analog camera to the device, there is no video output.

There are following possibilities:

• Check camera power supplying, data cable connection and etc.
• This series device does not support the analog camera of all brands. Please make sure the device supports general standard definition analog camera.

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

There are following possibilities:

• Check camera power supplying, or camera data cable connection.
• 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 and then restart the DVR.

I can not connect to the IP channel.

There are following possibilities:

• Check the camera is online or not.
• Check IP channel setup is right or not (such as IP address, user name, password, connection protocol, port number.).
• The camera has set the whitelist (Only the specified devices can connect to the camera).

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

There are following possibilities:

In this way, the DVR can recognize the analog standard definition.

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.).
