Network cameras, also known as IP CAMERA (IPC for short) by the combination of network coding module and analog cameras. The network coding module will be analog cameras captured analog video signal coding and compression into digital signals, so that you can directly access the network switching and routing equipment. Network camera built-in an embedded chip, using an embedded real-time operating system. Network camera is a traditional video camera and network video technology combined with a new generation of products. The video signal transmitted by the camera is digitized and compressed by a high-efficiency compression chip, and then transmitted to the Web server through the network bus. Users on the network can directly use the browser to view the camera images on the Web server, the authorized user can also control the action of the camera PTZ lens or the system configuration for operation. Network camera can be more simple to realize the monitoring, especially remote monitoring, simpler construction and maintenance, better support for audio, better support for alarm linkage, more flexible video storage, a wider range of products to choose from, more high-definition video effects and more perfect monitoring management. In addition, IPC supports WIFI wireless access, 3G access, POE power (Power over Ethernet) and fiber optic access.
Applications
Broadband information network in addition to providing high-speed network access can also replace the coaxial cable image transmission lines, real-time image monitoring into the broadband information network applications, which makes the information network instead of the traditional closed-circuit television has become a necessity PC-based multimedia surveillance system is more powerful, but the main monitoring of a small area. When the transmission distance or the need for Internet access, PC-based multimedia monitoring stability is not good enough, high power consumption, the need for someone to guard, the openness of the software is not good. These problems provide a stage for network video surveillance based on network and embedded technology.
Network cameras convert images into packets based on the TCP/IP network standard, so that the images captured by the camera through the RJ-45 Ethernet interface or WIFI WLAN wireless interface directly to the network, through the network can be monitored remotely on the screen.
The network camera adopts the most advanced camera technology and network technology, with powerful functions. The built-in system software enables true plug-and-play, eliminating the need for complex network configurations; the built-in high-capacity memory stores images before alarms are triggered; and the built-in I/O ports and communication ports make it easy to expand external peripherals such as access control, infrared sensors, and omni-directional pan-tilt heads. Provide software package (SDK) to facilitate users to quickly develop their own application software.
Network cameras are widely used in education, business, medical, public **** business and other fields.
