The development of video surveillance systems is divided into the first generation of analog video surveillance systems (CCTV), relying on special equipment such as cameras, cables, video recorders, and monitors. Its limitation lies in its excessive reliance on the quality of the video equipment, affecting the ambiguity in the long-term preservation process. The second generation is based on the "PC+Multimedia Card" digital video monitoring system (DVR). The "analog-digital" monitoring system is based on a digital hard disk recorder DVR as the core semi-analog-half-digital solution. The risk of disk failure is related to RAID redundancy and tape. In contrast, "analog-digital" video recordings are not protected and are easily lost. The third-generation all-IP video surveillance system has enormous advantages: Simplicity - All cameras are simply connected to the network via cost-effective wired or wireless Ethernet, enabling you to use existing LAN infrastructure. Easy to upgrade and fully scalable - Easily add more cameras. Central servers can be easily upgraded to faster processors, larger disk drives, and greater bandwidth in the future. Comprehensive remote monitoring - any authorized client can access any camera directly. You can also access the monitoring image through the central server. Robust Redundant Storage - SCSI, RAID, and tape backup storage technologies can be used to permanently protect monitored images from hard disk drive failures.
As far as the current market is concerned, we have been working hard to promote the improvement and upgrading of third-generation video surveillance systems and make its services more user-friendly. In fact, it is to ensure that it protects real-time performance and security. The expansibility and flexibility are based on the ease of operation and the convenience of the user experience. Under the cloak of high-end technology products, it has become a product that can really provide services and guarantees for ordinary people. I hope in the near future. Video surveillance systems, like computers and mobile phones, go into millions of households and can be carried around at any time to issue instructions to improve the safety index and happiness of each citizen.
All kinds of solid waste in life can be made into garbage derived fuel after sorting, dehydration and shredding and compression. This derivative fuel is called RDF pellets. RDF pellet has good air permeability, uniform particle size and high calorific value, and is a good combustion material in RDF gasification power generation plant. After the RDF pellets are pyrolyzed and gasified as fuel, they can drive the generating units to generate electricity. This process can also be called RDF power generation. Rdf Power Equipment is different from Msw Power Plant. It has higher purification degree and higher efficiency. It is a kind of Msw Power Equipment with higher environmental protection benefits.
