Network camera is a new generation product which combines traditional camera and network video technology. In addition to all the image capturing functions of general traditional cameras, it also has a built-in digital compression controller and a Web-based operating system, so that video data can be sent to end users through local area network, Internet or wireless network after being compressed and encrypted. Remote users can use the standard web browser on PC to access the network camera according to its IP address, monitor the situation of the target site in real time, edit and store the image data in real time, and control the pan/tilt and lens of the camera for all-round monitoring.
