Nonetheless, conventional CCTV setups face numerous obstacles, complicating the task of security teams in identifying and addressing potential threats.
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.
Definition of CCTV Systems:
Closed-circuit television (CCTV) systems refer to a network of cameras and recording equipment used for surveillance purposes. Unlike broadcast television, the signal in a CCTV system is not openly transmitted but is instead monitored, typically for security and surveillance purposes. These systems are prevalent in various settings, capturing and recording footage that can be reviewed or monitored in real-time to enhance security, deter crime, and assist in investigations.
