In a large environment, wired surveillance system is sometimes preferred knowing that wired connection is more reliable than wireless connection even though you need to run complicated cable installation between each of the camera to the DVR or NVR system. On the other hand, wireless security camera system is easier to setup no need to running complicated wired cabling because data is transmitted via wireless connection.
Please note that in the following article we are talking about NVR (Network video recorder) not the DVR. We still use the DVR because many people still stuck with DVR terms instead of NVR. We are not talking about the difference between NVR and its predecessor – the DVR. However at least you know the main difference is about where the video is encoded.
In a nutshell, Video on a DVR is encoded and processed at the DVR and commonly the camera connects to the DVR via BNC cable, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing via a network cable and mostly each camera supports PoE (Power over Ethernet). With PoE feature, each camera needs a single CAT5e cable for both data and power.
Most DVR / NVR camera system with large number of channels (16, 24 and more) are wired connection between the camera and the NVR camera system either BNC (DVR system) or Network PoE cable (NVR). PoE network cable is sometimes preferred, however the distance between the camera to the NVR is limited to total length of 600 ft compared with BNC cable that can be run up to 980 ft.
