When a camera leaves the "exclusive" walled garden and connects via ONVIF, it generally drops down to being a "dumb" camera. It can only send a basic video feed. In an exclusive setup, the NVR and camera share processing loads. For example, the camera might detect a human, send a low-resolution metadata alert to the NVR to confirm, and then have the NVR tell the camera to record in 4K. This inter-device communication is impossible in open systems.
While most enterprise network cameras are wired for stability, "Wireless Network Cameras" represent a specific sub-category.
