Difference between hard disk video recorder and embedded hard disk recorder

Difference between hard disk video recorder and embedded hard disk recorder

Answer:

From the system function, PC type digital hard disk video monitoring system (hereinafter referred to as PC) and embedded digital video monitoring system (hereinafter referred to as embedded) did not have great difference, both of which can achieve such as PTZ control, playback retrieval, multi screen monitoring, password protection, automatic video, mobile detection alarm and restart function calls however, PC products can generally use the PC platform, can achieve more auxiliary functions, such as: electronic map, image capture, print, and PC as a result of an open operating system, expansion and extension function only to modify the software can be relatively easy, and embedded with the special system function extension needed to operate the hardware, relatively difficult.
PC type generally used to insert the video compression card to build its hard disk platform, according to the requirements of the stability of the equipment can be used in different industrial or commercial host host (host computer stability and robustness compared with the commercial host high, but the price is a lot higher, such as SN2000 PC series of products in order to improve the stability. Using the host computer). The embedded host is dedicated to monitoring and development, reduce unnecessary hardware, while strengthening the monitoring function, the general operating system specifically for monitoring the need and the development of the operating system (for example, SN-DVR is used in PSOS embedded operating system).
PC generally use the windows operating system (as well as some products using Linux operating system), all operations are completed by computer, which requires the operator with some computer knowledge, and before the operation quite often the manufacturer for training. The special embedded operating system commonly used, operation is completed by the control panel or remote disk recorder on the function keys, the operation is relatively simple, and does not require the operator to have professional knowledge, because of the humanized design, the operator only needs simple training to master the operation of equipment.
From the above we can see, PC type powerful, and embedded products are more stable. This is one of the reasons are as follows: 1. The embedded operating system is relatively simple, designed for monitoring needs and development, remove some unnecessary functions, and hardware to write embedded host, and the windows operating system, not only is developed for monitoring, its main function is the management of the computer. Provide powerful auxiliary functions for individual users, such as the Internet, word processing, the storage disk in computer, so the operating system of embedded type is more stable than PC; the embedded hardware using modular design, and for monitoring to be developed, the hard disk is mainly used for monitoring records data and function of PC is more consideration for the personal computer user, the hard disk to record the operating system, other users of personal data and stability Nature can not be compared with embedded.
