Talking about the principle of encoder correctly understanding the encoder
February 20, 2021
Encoder does not seem to bring obvious advantages in the analog monitoring system, but in the network monitoring system, the encoder has set up a bridge between monitoring storage and transmission. In the face of different monitoring architectures, the encoder did not exert its original strength. So now let's talk about the principle of the encoder.
The IP-based video surveillance system has many advantages, in which the image quality is improved by at least 30% over the analog system. Network scalability and operating costs are lower, and more convenient is that users can control the management through the computer. Obviously, these are not available in analog CCTV surveillance systems.
IP video improves picture quality, improves management, and reduces system operating costs. In addition, it also provides a future-oriented platform, and good network technology is always ready for the megapixel and HD era.
The video encoder converts the signal input from the analog camera into a digital video stream. Common compression standards such as M-JPEG, MPEG-4 or H.264 output video formats will be the same and can be fully integrated into network cameras and networks. Video system. Codec also built-in features include video motion detection, tamper alarms, and video analysis.
Considering that the average service life of analog surveillance cameras is 5-7 years, many people think it is quite a long time. Some operators have already focused their investment in installing coaxial cable into buildings without Ethernet infrastructure. By changing the image quality through the encoder, the reward effect is fast, and the trouble of paying a new IP address is also saved.
The camera is not God. It is not irreplaceable. If you want higher image resolution, according to the current simulation system, it is difficult to complete your needs. Of course, you should also remember that megapixel cameras may increase the storage burden and HD cameras produce larger files. Digitizing analog clips can also affect network bandwidth. Correctly assessing the advantages and disadvantages is the most scientific method.
Finally, encoders bring many advantages to IP cameras. You will want a single video management system to record and access all cameras. IP video management software only supports IP video streaming, so you need to convert the purchased analog video stream encoder into an IP video management software that can process IP signals.
