What's the difference between digital camera, network camera and analog camera?

Among the three, the performance of analog camera is the lowest. The difference between a webcam and a digital camera is whether it can be shared with a remote audience. Digital cameras can, but webcams can't.

The signal output by analog camera is a video signal, which can only transmit one-way video signal, and it needs to be connected to a monitor or a hard disk video recorder for monitoring and recording.

Network camera (IP

Camera is a video compression and network transmission processing module (DVS) integrated on the basis of analog camera, which has the technical characteristics of both analog camera and video server.

Digital (IP) camera (hereinafter referred to as IP camera) is a new generation camera which combines traditional camera and network technology. It can transmit images.

Through the network to the other side of the earth, and the remote browser does not need any professional software, as long as the standard web browser (such as "Microsoft

IE or Netscape) can monitor its images.

Webcam is also called IP.

C

AMERA (IPC for short) consists of network coding module and analog camera. The network coding module encodes and compresses the analog video signals collected by the analog camera into digital signals for direct connection to network switching and routing equipment. The webcam has embedded chips and uses an embedded real-time operating system.

IP network camera is a digital device based on network transmission. The network camera not only has a common composite video signal output interface BNC, but also has a network output interface, which can directly connect the camera to the local LAN.

With the development of social economy, there are more and more group companies, and the business activities between branches are very frequent. As the leader of an enterprise, he often needs to travel around, inspect subordinate companies and participate in various business activities. With webcams, they can also grasp the situation of companies and factories in a timely and intuitive way through the network in different places. Due to the influence of the external environment, there are network cameras suitable for indoor and outdoor. Adopt professional CCD photosensitive chip, hemispherical protective cover, waterproof and high temperature resistant, inhibit strong light and infrared night vision. Can adapt to harsh outdoor environment and support wireless routing.
