High-definition monitoring application technology started from the top
In this year's GDSF digital monitoring forum, high-definition is still repeatedly emphasized monitoring technology, which can be a large number of high-definition products from outside the IP network cameras, including a large number of HD-SDI matrix and digital HD cameras and SDI-DVR digital high-definition High-definition HD video technology applications such as video recorders, SDI video servers, and SDI optical fiber transmission and conversion interfaces have been added to allow engineering companies to have more layers of high-definition applications and technology options for high-definition IP networks, as well as IP networks. High-definition technology is surpassed by full-HD technology to reach ultra-high-definition surveillance technologies such as 5 million and 8 million. This can also be seen in the newsletter about one-third of the companies in this forum briefing the topic. Of course, some manufacturers will not forget the high-definition analog HD in the GDSF activities, in addition to HD-SDI; some manufacturers also use this opportunity to 960H high-line analog video camera application technology in this activity to explain With the introduction. The application of these three types of high-definition high-definition camera technology allows us to see that high-definition monitoring application technology is not in the growth of a technology and market, but in this same integrated high-definition system. Under the application technology, high-definition monitoring is starting from its peak position.
Reducing bandwidth load becomes a technical consensus
High-definition monitoring technology has been extensively explored in this forum. In fact, there are two core technologies in which almost all participating GDSF manufacturers will focus on exploring and publicizing Yang's technical priorities. The first and more important is “How to reduce HD monitoring? "Broadband bandwidth demand", which of course refers to the situation and requirements under the high-definition network monitoring conditions, but in fact, in the integration of various high-definition, not only IP network HD, but also in the SDI and 960H back-end In digital storage and transmission, bandwidth loading and smoothness are still one of the technical obstacles that we face inevitably. It's not difficult to see how the content of the company’s newsletter and how many adjectives are used in the entire GDSF campaign. Learned about the vendor's concern and emphasis on this issue. Here, we also share the following 11 ways of reducing the HD video content conditions and bandwidth load through the manufacturer's data and our comprehensive review to discuss with you whether these technologies are more advanced or missing. In this way, these 11 techniques for reducing network monitoring bandwidth are as follows:
1. Image Cropping: Cut unwanted parts of the sky to reduce file size, dynamically crop invalid images, reduce data flow, and reduce compression pressure
2. According to different light automatic switching mode (Day / NightModeAdjustment): the use of the default mode (Day, NightModeautoswitch) allows the camera to adjust to the environment with the best image quality to reduce the image data flow.
3. E-PTZ electronic local amplification application: the use of local electronic amplification to reduce the screen optical amplification to be a larger bandwidth, the electronic PTZ to electronic focus on the local fine picture.
4. Edge Storage: The camera uses a SD card slot and memory card as a temporary storage mechanism at the front end of the camera. It stores the data at the front end of the “zero seconds†line of the image disconnection, and recovers and returns the compensation and HD compensation.
5. AAS (Activity Adaptive Streaming) dynamic adaptive video stream adjustment: Dynamic adaptive video stream adjustment, generally one million network cameras, supports activity self-adjusting streaming to dynamically allocate bandwidth using the screen playback rate based on specific needs. For example, normal monitoring can identify the image only when needed, and the picture playback rate during the period can be set as low as 1 fps - to reduce bandwidth usage.
