What exactly is a network video encoder, a network encoder, it is a professional network transmission device that compresses and processes audio and video data, also known as network editing, and there is a device called network video decoder (commonly known as network solution), The network video encoder is used in the front end, and the network video decoder is used in the back end. The two can be understood as a two-way transmission channel. After the data is encoded, it needs to be decoded and restored. The two are complementary.
Basic composition of network video encoder
The network video encoder is composed of audio and video compression codec chip, input and output channels, network interface, audio and video interface, RS485 serial interface control, protocol interface control, system software management, etc. If it is applied to network video surveillance, it can be understood as a front-end device of a remote monitoring system, with an external camera and an alarm signal, which can be automatically dialed and registered to the central monitoring business platform to achieve remote monitoring.
The function and workflow of network video encoder
The network video encoder mainly provides video compression or decompression functions, completes the collection or restoration of image data, etc. At present, the more popular image data compression based on MPEG-4 or H.264 is the processing of transmitting data and audio data through the Internet network.
The work flow of the network video encoder is to combine video and control on a computer network for transmission, and restore the original appearance of the video signal at the network solution. Through the hard network solution, you can get a direct video signal, you can also connect the control keyboard to control the lower end device; through the soft network solution, you can browse and control on the computer network. Upload the front-end video signal and download the back-end control signal. The downloaded control signal can control the front-end equipment such as the matrix picture processor alarm. When the multi-level center is sent to the general control center, it has a strong advantage in cross-city and inter-provincial networking. Due to the diversity of the equipment, the network protocol and network solution purchased directly from the bottom protocol are different, and need to be used after secondary development.
Let's talk about the steps to implement the application of network video encoder in video surveillance
1) Required equipment
Network video encoder, network camera, PC that meets the requirements (CPU, hard disk, memory, operating system, browser, graphics card, these are the right choices according to the requirements of the network camera)
2) Install network video encoder and network camera
Design PC network, network video encoder and network camera need to be set in the same network segment, you can manually set or automatically obtain the form of IP, please refer to the product manual for the specific setting form;
3) Configure network equipment
To configure the network equipment with the authority of the administrator, you need to open the browser to access through the IP address, enter the administrator's account and password, you can enter the main settings interface, you can see the remote monitoring screen, find the relevant parameters in the main settings interface Set point, you can set the relevant parameters of the network camera. The interface of each network camera has its own style. I will not explain it here. Interested friends, if you have the opportunity, you can do it yourself. Set it up.

Overview of the development of network video encoders
Due to the increasing demand for network monitoring, manufacturers of machine vision, especially manufacturers of industrial cameras, are striving to develop in network cameras, which indirectly also promotes the development of network video encoders. At present, network video encoders have been developed by Single-function video transmission has gradually developed into a WIFI network, with local SD card storage, or USB storage or IDE hard disk storage, etc .; the transmission channel has gradually evolved from the original single channel: single D1, two HD1, four CIF An integrated system for multi-menu operation and management compatible with multiple channels.
At present, the communication method of the network video encoder has also gradually developed from the original pure wired network: wired and wireless WIFI (802.11abg communication protocol) compatible, and the wireless transmission distance is also from the original tens of meters (30-100 meters) , Developed into the current tens of kilometers (30-50 kilometers).
We know that an encoder is a device that compiles and converts signals or data and transmits them. The network video encoder is just one of the most common applications after the development of the encoder, and it is successfully applied to network equipment and has been recognized and applied by the majority of electronic engineers.
