[ Huaqiang Security Network News ] It is understood that with the rapid development of the video surveillance industry, the storage methods of devices in video surveillance equipment are constantly updated. From the current point of view, security surveillance storage is mainly in the following three ways: 
1, NVR storage. NVR (Network Video Recorder) is a product form that has gradually emerged in the Chinese security market in the past two years. In the video surveillance system, the NVR is an upgraded product of analog video recorders and hard disk recorders. It is implemented on the basis of the original DVR. A single-machine independent operating device that is compatible with the window operating system and the computer. Because the NVR adopts highly integrated chip technology, it has advanced digital recording, storage and playback functions, eliminating the need for computer coordination and routine maintenance. Therefore, it can achieve higher resolution (up to D1 resolution) and high-quality real-time monitoring. And easy to use.
2. DVR storage. In the late 1990s, digital video processing (DSP)-based digital video surveillance began to become popular. Various codec technologies have been widely used in image processing. The processed images can also be transmitted in digital code streams. The storage also began to enter the digital era. The most typical application is a digital hard disk recorder (DVR), which uses an internal hard disk for image storage.
3. Centrally manage storage. The server connects to the front-end codec, downloads the data through the streaming protocol, and then stores it on the storage device. Servers and storage devices can be connected through SAS, iSCSI, NAS, and FC protocols. Centralized storage is suitable for deployment of large and medium-sized platforms. Among the centralized storage methods, the IP connection mode (iSCSI) and the FC connection mode have good scalability and manageability, and are one of the more adopted methods. In terms of actual deployment and effect, FC storage is more suitable in monitoring environments with more nodes due to its powerful performance and data processing capabilities. IP storage can be more suitable for small and medium-sized applications due to performance and scalability limitations. High cost performance.

The pump controller controls the pump so that it can absorb the output point of the engine.
For all the torque, these torques depend on the mode of pump absorption.
Torque specification, fuel control knob setting and actual engine speed.
