Network HD camera is the star of the future

In the current industry standard, the network HD camera mainly refers to digital cameras with resolutions of 720P and 1080P. Many people in the industry predict that the network HD camera will be the star of the future. Why do you say that there are many factors, and listen to the author.

First, the aspect ratio of the network HD camera is defined as 16:9, 720P is 1280*720 resolution, and 1080P is 1920*1080, where the suffix "P" stands for progressive scanning.

For image acquisition of moving targets, relative interlaced scanning, progressive scanning can obtain better dynamic images, and progressive scanning is more suitable for security monitoring applications. Image quality is the most important requirement for monitoring. Monitoring scenes vary widely. This requires surveillance cameras to adapt to the complex light of various scenes and achieve excellent image quality. Image quality contains a lot of content: color reproduction. Whether the camera can truly restore the image color of the actual scene, whether the white balance is accurate, whether there is warm or cold, and the focus accuracy. Whether the camera can focus accurately under various lighting conditions without defocus or hesitation. Image, excellent sensitivity; low illumination performance. Can the camera get bright in low light conditions; wide dynamics. In the scene where the light and dark contrast is strong, the camera can balance both the bright area and the dark area, and the dynamic range is large enough; the dynamic effect. Whether the edge of the moving object is clear and there is a tail. Secondly, the performance of network transmission is very important for network HD cameras. Because HD cameras transmit images with larger resolution and more information than ordinary standard definition cameras, objectively put forward higher requirements for the network. Many aspects, such as the impact of maximum resolution on bandwidth, several encoding methods, several code streams, real-time, support for wireless networks, etc., need to be considered. In addition, the stability and durability of the camera are also factors that must be considered. The environment in which the surveillance camera is installed is very complex and can be encountered in a variety of harsh environments. If the camera itself is not capable of adapting to the environment, it is very easy to malfunction and not work when installed in a harsh environment. Sony products are targeted at professional-grade applications and have been designed with a wide range of operating conditions in mind to allow them to work in a variety of applications. Finally, high-definition compatibility and high-definition standardization are issues that cannot be ignored. The ONVIF specification describes network video models, interfaces, data types, and data exchange methods. It defines a standard process for communication between network video sending devices and network video clients. These interfaces make it possible to use a video transmission device from different vendors to form a unified network video system. And this important network camera architecture is being promoted and developed on HD cameras, and future HD cameras will inevitably be developed and produced with this standard.

Through the above understanding, we have a further understanding of the development of network HD cameras, this will be a starting point for a leap, let us run on the starting line, believe in the power of the future star.
