Video IP Address How To
Last Updated 3/27/2017
In a nutshell, IP video is simply a method for transmitting images over a network connection. The process begins when an analog video signal is digitally encoded or compressed. The signal can then be transmitted using a standard protocol – TCP/IP.
The advantages of IP Video can best be highlighted by looking at the disadvantages of analog CCTV. The analog matrix is the component that provides control room flexibility for analog CCTV systems, but this too cannot be easily expanded without adding new hardware and it is location dependent. Therefore overall scalability, i.e. the cost of expansion, is poor. Even though the introduction of DVRs has improved the recording capabilities of analog CCTV, these too are limited. They have to be physically installed near the analog matrix, and frame rate and image quality is often compromised. Businesses want a single, scaleable, integrated solution which provides high-quality video surveillance across any number of their offices or sites – this is what IP Video delivers.
Manufacturers of IP Video equipment provide excellent tools for helping security and IT professionals design digital CCTV systems and in particular compute the bandwidth requirements of the network. The process is simple. You should decide how many cameras are going to be installed, decide at what quality the recording will be made, and of course the period required to be recorded. All of this will help to estimate how much bandwidth and recording storage is needed.
