Each IP network camera has its own IP address, data processing function, and built-in application software. It can be used as a web server, FTP server, FTP client, and mailbox client. Many advanced IP network cameras also include their special functions. Such as motion detection, alarm signal output / input device and mail support function.

Network surveillance cameras not only support all standard analog CCTV camera functions, but also provide users with more system functions and can reduce more costs. Because the network surveillance camera can be directly inserted into the existing data network and applied via Ethernet, it can save the company thousands of dollars in wiring. At the same time, the network surveillance camera can work independently on the PC and the image can be used with a standard web browser Read.

In addition, the network surveillance camera also saves the company a large number of specific monitoring equipment and systems, because the system can use IP machines for real-time management and monitoring in any corner of the world through the network. The analog CCTV system requires special monitoring equipment and security personnel who are responsible for monitoring the image.

Create a new era of high-tech surveillance. Network surveillance cameras can continuously transmit real-time image signals of 30 frames per second through a standard web browser via a coaxial CCTV system and a computer network. Leaders of technology have developed pre- / post messages including tracking detection and alarm, transmission of short messages via e-mail and mobile phone text messages, and the centralized application of wireless and wired technologies will promote clearer image transmission.
