Key words:
HD number, video
With the development of society and the economy, security monitoring systems are gradually popular in various industries, and the problems in traditional video surveillance are also incident. One: Traditional monitoring is generally CIF-D1 resolution, and the image sharpness is not high. Once the case occurs, the image detail extracted from the portrait face extracted in the video is unclear, so that the video data is worthless. Second: Traditional monitoring usually needs to lay a video, audio, power, control, and alarm, etc., etc., management and maintenance are quite difficult. Third: Traditional monitoring is often configured with many devices such as video switches, video distributors, video matrices, decoders, hard disk recorders, monitors, complicated structures, and inconvenient expansion. These are seriously restrictions on security management efficiency. How to get out of traditional monitoring?
How to get out of traditional monitoring?
On some small and medium-sized video surveillance projects, users often follow the construction ideas of traditional video surveillance. Video surveillance projects with a certain size or safety level require more attention, users often pay more attention to image quality and monitoring the overall service capabilities of the company, so in this area, HD digital video overall solutions have more advantages. Sichuan Eppers Digital Technology Co., Ltd. (hereinafter referred to as Aipstar) is one of several manufacturers in China to provide HD hardware codec equipment and HD video management software overall solutions.
Aipstar's latest standard H.264MAINPROFILE million-based pixel HD product provides high-definition image effects, supports full HD, full real, dual stream digital video processing, and provides a wealth of input and output interfaces. HD low-code flow video is fully suitable for transmission in LAN and fiber optic networks, and is also convenient to expand and maintain; the data hard disk and storage servers on IT are main media, with high-definition liquid crystal displays, plasma splicing walls, etc. The platform has matured by large projects such as Ping An City in the past two years, and the architecture is mature, and the management center platform can be easily compatible with millions of pixel HDs based on standard H.264 standard compression code streams. These are marked with millions of pixels HD era!
Standard H.264 million pixel HD network camera
Taking the AIPSTAR AS-NC200 Series Million Non-Pixel HD Network Camera products as an example, HD network camera products have many excellent features:
· High compression ratio, strong compatibility. The standard
[email protected] compression algorithm is used to have a picture quality than the MPEG-4 multiplication at the same code rate. Under the same picture quality, the code rate is only one-half of MPEG-4 (bandwidth) ). And the video files in standard H.264 format can use standard decoder decoding (eg storm video, VLC, Coreplayer, KmPlayer et al), higher device versatility and compatibility;
· Have a wider visual area. The 720P resolution visibility is twice the D1, and 1080p is 5 times the D1. In some areas (such as road monitoring), HD video can display more panoramic images, or save the number of cameras. HD 16: 9 widescreen display can bring a broader visual shock. From the visual effect, its image quality can be reached or close to the level of 35mm wide silver movie. From the picture quality, the screen is sharp, and the color is still far better than the full D1 standard clearance network camera;
· More delicate picture quality. Million pixel HD cameras have more delicate detail, even if local zoom is large, the details are still perfect;
· Real high definition. At the same symptom, the sharpness is 2-3 times the D1. 720P HD network camera image level resolution up to 720TVL, 1080P HD network camera image level resolution can reach 900-1000TVL;
· Million pixels are scanned. Scanning the CMOS image sensor by means of a high-resolution of millions of pixels to ensure that the video source is clear enough. Improve line-by-line scan can effectively avoid problems such as motion blur and tear of interlaced camera images, and the picture is more delicate and touching;
· High-definition real dual stream meets different application needs. At the same time, the 720P (1280 × 720) and all the way 25 frames / sec1 (720 × 576) real-time video images are transmitted. You can also choose a real-time video browsing, all the way to the alarm capture image to meet different industrial needs. Even 1080p resolution format is also a 25fps full frame rate real-time browsing, but users can not only see continuous images, and they will not miss or miss any critical events;
· 3A control. Built-in 3A control circuitry automatically adjusts white balance (AWB), automatic gain (AGC) and automatic exposure (AEC). Combined with DC driving automatic aperture lens, automatic exposure control and drive lens aperture can reach optimal exposure and image quality;
· Real one line. Power supply, webcam power, image data, alarm data, and RS485 PTD control data by PoE Ethernet, and reduce costs for engineering wiring, installation and maintenance, and smaller power consumption is more stable;
· A variety of browsing methods. You can browse through the web way, monitor your monitoring through PPC smartphone or centralized monitoring through the management center platform;
· A variety of video triggers and storage methods. You can turn on your video, video movement detection recording; sensor linkage video (available for road monitoring capture). Alarm video or scratch picture can be stored in a built-in SD / SDHC card or upload to the FTP server; you can also store the user diversification application requirements via NVR local records or through the IPSAN storage area network set.
High-definition digital video management center platform based on standard H.264
Even with a million-pixel HD network camera, it is still necessary to face multiple HD network cameras centralized management. Good horses are equipped with saddle, and the management center is also a set of mature and stable HD management system platform centralized management. Taking the VMP HD Digital Video Management Center of Aipstar as an example to analyze the HD integration solution, how to make you slow!
· Modular components. Managing the Center End Performs can be subdivided into different modules (such as directory server as-dus, management control center AS-MCS, electronic map server AS-AMS, network video storage server AS-VSS, virtual matrix decoding server AS -VMS, streaming video forwarding server AS-VTS). Different modules are combined for monitoring systems for different sizes;
· Multi-user core authentication management. Based on multi-user authentication management technology, a centralized authorization of any device browsing, control, administering, and priority for a user; multi-user priority and conflict detection can be implemented under complex network conditions. The user is more beneficial to establish a temporary command center in any of the system in the system, and the emergency emergency should be handled.
· Stream media video forwarding. Based on standard H.264 streaming and multi-code streams such as multi-channel cross-access, the network bandwidth and central system load issues brought by multi-channel cross-access can be solved, maximizing the system operation stability;
· Multi-screen display. With modular components, different screens are used to display and control different screens. It is also possible to display a multi-screen display for centralized management control;
• Connect the video on the electronic map window. The user can connect an image of a monitoring node on the electronic map with a custom electronic map, and quickly respond. If viewing confirmation alarm information, alarm forwarding, and clothing preventive operations, enhance user experience and management efficiency;
· Remote status monitoring. The VMP Video Monitoring Management Center automatically collects the working state of each front-end device host, timely discovery network and front host failure, timely alarm notification is excluded;
· High-definition decoding and TV wall control. Through the H.264 HD video hardware decoder, the system can support 1080P, 720P and FullD1 and other format HD video decoding outputs. With the VMP video management platform, multiple TV wall switching and wheel tour are available.
