IP high-definition cameras have ingeniously surpassed the traditional analog cameras. Nowadays, high-definition surveillance cameras on the market have formed a diversified product pattern based on megapixels with 2 million pixels and 3 million pixels. An IP HD network camera is mainly composed of video capture, video encoding, and network transmission. An IP HD camera can be seen as a combination of a HD camera and a computer. It performs progressive scans through CMOS/CCD photoreceptors, enabling optical signals to be captured directly and processed on a single SoC chip for direct transmission over an IP network, enabling users to access local or remote locations over a standard IP-based network infrastructure. Enables viewing, storage, and management of high-definition video data.
The most important technical application features of IP high-definition network cameras are high-definition images brought by high-pixel images, and multi-region networking and remote control can be easily realized through network transmission, which is very important for security monitoring:
1) Larger coverage As mentioned above, one of the advantages of IP HD cameras is that they have a wider coverage and the same surveillance area can replace multiple fixed-point cameras or omnidirectional cameras. For intensive locations, such as airport security gateways, stations, subways, shopping malls, entrances and exits, parking lots, factories, bank tellers, etc., it is generally necessary to design multiple dense low-resolution cameras to protect the dead ends, and now, deploy IP HD The camera is a good choice.
2) Image quality is better. The so-called "details determine success or failure", IP HD camera uses advanced photoreceptors to make the image details clearer, especially for moving objects, progressive scanning can give us better image quality, effective It solves the comb-like blur caused by interlaced scanning. Reliable image quality + detail = reliable and fast investigation and analysis, so that the video storage of a large number of hard drive data is valuable image data, which is of great significance for license plate, face recognition and other applications. On the contrary, if the image quality is poor and the lack of detailed information will undoubtedly bring great difficulties to the investigation and analysis work in the future.
3) Multi-regional networking is more convenient With the popularization of IP high-definition network cameras, the high-end embedded NVR products of the back-end products are becoming more and more abundant, which plays a very important role in the popularization of network cameras, especially IP high-definition cameras. The important role is to record and store the network video stream, and provide real-time display and proxy forwarding. Generally, the embedded architecture is used, and the hard decoding supports multi-channel network standard definition or high-definition camera access. Take the embedded NVR of Tiandi Weiye as an example, it can support the access of 16 road signs or 8-channel high-definition network cameras; embedded hard decoding, real-time preview and video recording; built-in hard disk storage can be stored; built-in proxy forwarding module can The accessed video stream is forwarded;
In addition, it also has two output interfaces, VGA and BNC, which can decode the upper wall display. In addition, it can also be used as a node device to perform node monitoring and distributed storage in the system. The IP high-definition network camera can greatly improve the interconnection and interoperability through the IP network, realize the interconnection and intercommunication of multiple platforms, integrate the entire social resources, and link the various command centers and information centers to realize information exchange and resource sharing. The technology is compatible, which is conducive to the sharing of social resources. The processing of various events can respond effectively and quickly. The "plug and play" usage mode provides flexible extension functions.
