It is known that the video monitoring is an important part of the safeguard system, and more and more industries attach great importance on this system. There are so many elements which bring a revolution to the security industry, such as the development of network and information technology; the government’s great investment on the manufactures. As an essential component of the security system, the video monitoring is developing from the simulation system to the network video monitoring. The intervention of the network device manufacturers make the components of video monitoring develop towards intelligence, network.

The traditional memory method store the image develops from the hard disk video recorder to the DAS or San. The various names make people confuse. When it comes to the traditional solution, there are two kinds of products, the PC DVR and embedded DVR. Generally, the control and expansion of the function is implemented by the IDE keyboard of the DVR. The data of image is input in the order; therefore, the special hardware will always have so much potential. If the requirement for quality and real-time performance is high, the quantity of data will increase. The non-professional products of the DVR have not considered fully about the heat radiation and the protection of hardware. These products are only suitable for the small monitoring system, which has low requirement of the data memory, because the cost of these products is low. What is more, the solutions of DAS and NAS are also very traditional.

The SAN and NAS make the development of IP memory mature. The SAN is short for storage area network, which is a kind of storage architectures. There are many advantages of the SAN, for example, It is able to integrate the different devices and data; the cost is low. The related integrated circuit is TA8225H.
