Applies to: All DVR
Let us take a DVR as an example to answer this question.
The DVR has 3 modes.
Mode 1: only analog mode
Analog cameras can be plugged into DVR directly, and no IP cameras could be added to the DVR.
Mode 2: network mode(IP Camera)
IP cameras can connect the system, but the analog cameras can't connect to the DVR anymore.
Mode 3: mix mode
Both analog cameras and IP cameras could be added to the DVR based on the channel type.
Note: The system can only be in one mode.
1. If you want the system to connect IP camera, you need select mode 2 or mode 3. But in mode 2, the system is not able to work with analog cameras. Do you mind that?
2. The IP camera cannot be plugged into DVR to get the image. They must be plugged into the router first. Here is the example about how to hook up an IP camera to DVR:

Besides, there are two limitations to the IP cameras on the resolution and protocols. If the IP channel type is 1080P, it means that the max resolution of the IP cameras could be 1080P. Besides, the IP cameras need to support the ONVIF protocol.
3. To configure wireless function, you also need access camera on the phone or computer to set up wifi so that the camera can connect router by wifi instead of cable.
In other words, DVR can connect IP cameras. But whether or not the camera can be wirelessly connected to the router, it depends on the IP camera itself.
Generally, we don't suggest you use DVR to connect IP cameras.
