Network video, often also called IP-based video surveillance or IP-Surveillance as it is applied in the security industry, uses a wired or wireless IP network as the backbone for transporting digital video, audio and other data. When Power over Ethernet (PoE) technology is applied, the network can also be used to carry power to network video products. A network video system allows video to be monitored and recorded from anywhere on the network, whether it is, for instance, on a local area network (LAN) or a wide area network (WAN) such as the Internet.
The digital, network video surveillance system provides a host of benefits and advanced functionalities that cannot be provided by an analog video surveillance system. The advantages include superior image quality, remote accessibility, distributed intelligent video capabilities, easy installation and integration, and better scalability, flexibility, cost-effectiveness and easy, future-proof integration
The existing infrastructure, if analogue, can be easily integrated with the network video system using video encoders to ensure existing investments are not discarded. SDKs and APIs can also be used to integrate other products with video surveillance systems to add new capabilities and video-enable other business operations. The open platform video management software (VMS) reduces the total cost of ownership (TCO) by allowing client to choosing best of breed products for cameras, servers, storages etc.
