If you want to connect IP camera to DVR, three conditions must be met:

1. The IP camera should support onvif protocol.

2. The DVR should support connecting IP camera.

3. The resolution of IP camera should be equal or lower than the resolution of DVR's IP mode resolution.

When above conditions are all right, here are steps.

1. Connect DVR and IP camera into the same router with network cable respectively so that they are in the same network area. （If it is a wifi IP camera, it is OK that camera connects to router by wifi, not by ethenet cable）

2. Connect DVR to monitor.

3. Change DVR to IP mode or IP&analog mode. Syetem will reboot after you change mode. In System-Digital-Channel Type

4. Click plus icon in the middle. 

5. Click search, select the camera, click Add, input password and click Apply.

6. Check connection status. Click Exit. Live video appears.

If you find status is connected but there is still no image, please change video standard or reboot DVR to have a try.
