In the present-day context, security has emerged as a matter of utmost significance, particularly for individuals and businesses striving to safeguard their assets and people. While conventional video surveillance systems have long been relied upon, they come with inherent limitations.
The NVR eliminates these problems, because it is instead connected directly to a network. IP cameras that are connected to the same network, usually by way of a PoE switch, are then able to transmit footage to the NVR. Systems based around an NVR are much easier to scale up than DVR systems, simply because they can accept a new camera once it is added to the network. In the worst case, all that would be required is an additional PoE switch. Some IP cameras are also wireless and can transmit footage to the NVR over Wi-Fi.
