Surveillance system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed circuit. and it’s an independent and complete system from camera to display and record. Network surveillance solves the problem of traditional surveillance, effects and changes the traditional connection method, which is simpler and more convenient. but at the same time, it needs larger storage demand and higher bandwidth to match. The storage devices used in video surveillance systems have different characteristics from other types of systems in terms of data read and write methods. Surveillance system generally has the characteristics of many monitoring points (large number of cameras), large video data stream, long term storage requirement, 24-hours continuous and uninterrupted operation, etc.
