Video server knowledge!

The video server allows you to smoothly upgrade your video surveillance system to a web-based video surveillance system while retaining existing analog video surveillance equipment. It is ideally suited for integration with existing analog CCTV (closed-circuit television monitoring) systems. The video server brings new features to analog video equipment and completely eliminates the system's reliance on dedicated equipment such as coaxial cable, analog monitors, and DVRs. The DVR will no longer be a necessity for video recording because with the help of a video server, video images can be recorded and managed via a standard PC server.

A video server usually has 1 to 4 analog video input interfaces for connecting analog cameras and has 1 Ethernet interface for connecting to the network. Like the webcam, it includes a built-in web server, image compression chip, and operating system. Under these components, analog video input is converted to digital video signals and can be transmitted and stored over the computer network, greatly simplifying Video resource access and management.

In addition to the video input, the video server can also realize other more functions and transmit more information through the same network connection, including: digital alarm input and output (I/O interface, can be used to trigger the server to start video recording and Video transmission, or activation of external alarm devices such as lights or doors, etc.), audio, serial port lights for serial data transmission or PTZ device control. Through the image cache, the video server can also send images before and after the alarm. The video server can also be connected to more dedicated cameras, such as high-sensitivity black and white cameras, miniature cameras or micro-cameras.

Optical Brighteners are important raw material in Detergent, Textile, Paper industries.   DMS, CBS are mainly used for detergent field, such as: DMS is regarded as one of the perfect agent used in detergent industry, owing to introducing the morpholine group into the molecular, the properties such as acid and perborate resistance be improved. It can be used in the whitening of cellulose fiber, polymide fiber and fabrics, showing anionic characteres and has optical bule color, it has better resistance to chloride bleaching than VBL and 31#, the most favorable dyeing bath PH value is 7-10.  

BA & BBU mainly are used for paper industry.
