East video surveillance systems Contact 18889743218, Hainan Liansheng Technology trustworthy enterprises dedicated to audio-visual field, professional audio, lighting, video, multimedia conferencing systems, public broadcasting, closed-circuit TV, LED display, computer network systems integration and other projects the project design. installation, calibration services and other ancillary works. Calendar of years of wind and rain, grow up in a much-in. We thank the new and old customers the utmost support, we will always be your faithful friends, we would make every effort to provide you with the most satisfactory services. The first generation of video surveillance is a traditional analog CCTV video surveillance system (CCTV) cameras rely, cable, VCRs and monitors, and other special equipment. For example, the camera output video signals through a dedicated coaxial cable. Cable connected to a dedicated analog video devices, such as video Quad, matrix switches, cassette recorders (VCR) and video monitors. There are a lot of analog CCTV limitations: limited ability to monitor only supports local control, analog video cable transmission by cable length and limiting amplifier. Scalable systems typically limited by the video Quad, and the switch matrix input capacity constraints. Recording heavy user load must be removed or replaced with a new tape from a VCR to save, and the tape is easy to lost, stolen or accidentally erased. Video quality is not high is a major limiting factor. Recording quality decreases with increasing the number of copies. The second generation of video surveillance is the current "analog - digital" monitoring system (DVR): "analog - digital" monitoring system based on Digital Video Recorder DVR core half analog - semi-digital solutions, from cameras to DVR still using coaxial cable output video signal, supports recording and playback via DVR, and support for IP network access is limited. Since the DVR product variety, there is no standard, so this generation system is a non-standard closed system. DVR systems are still a large number of limitations: complex wiring "analog - digital" programs still need to be installed separately on each camera video cable, resulting in wiring complexity. Limited scalability limitations are a typical DVR can only extend 16 cameras. Limited manageability you need an external server and management software to control multiple DVR or monitoring point. Limited remote monitoring / control capability you can not access any camera from any client. You can only indirect access via DVR cameras. Disk failure risk compared with RAID redundancy and tape, "analog - digital" video program is not protected, easy to lose. The third generation is the future of third generation video surveillance IP video surveillance systems complete IPVS: there was a significant difference compared to all-IP video surveillance system of the previous two programs. Advantages of the system is a camera built-in Web server and Ethernet ports directly. These cameras generate JPEG or MPEG4, H.264 data files accessed by any authorized client from anywhere in the network, monitor, record and print, instead of generating a continuous analog video signal in the form of images. Full IP video surveillance system which is a huge advantage: simplicity - all the cameras are connected to the network via a simple, cost-effective wired or wireless Ethernet, allowing you to leverage existing LAN infrastructure. You can use Category 5 network cable or wireless networks transmit image from the camera and a horizontal, vertical, zoom (PTZ) control commands (or even directly via Ethernet for). Powerful central control - a set of industry-standard servers and control management application software can run the entire monitoring system. Easy to upgrade and fully scalable - Easily add more cameras. Central server will be able to upgrade to a faster processor convenience, larger capacity disk drives and greater bandwidth. Full remote monitoring - any authorized client can directly access any camera. You can also access monitoring images through a central server. Rugged redundant memory - which can use SCSI, RAID and tape backup storage failure affecting permanent protection monitoring image from the hard drive.
