1) Demand analysis: This article refers to the address: http:// Design requirements include video surveillance and anti-theft alarm systems; The camera is divided into two types: fixed installation and pan/tilt control, and optional uniform speed pan/tilt and high-speed ball with pan/tilt control; The control room requires that all camera images be monitored simultaneously; The control room is designed with a video wall function, which can display any camera image on the TV wall monitor through matrix switching; You can set up and set a schedule for the video work schedule. A variety of video retrieval methods are required. The system can store the image data of all cameras through the hard disk recorder, and the video data is automatically saved; Simultaneous control of various actions of the pan/tilt and lens through the matrix master keyboard and DVR (including up and down, left and right, lens zoom, near and far control, and high speed ball shift control and pre-position control); Important video material can be backed up and archived; The DVR has user rights management functions, and different levels of users have different usage rights. The alarm system can be disarmed at regular intervals; Support electronic map function, when a certain probe alarms, it is required to display the alarm point position in the electronic map. The alarm system and the video recording system are linked together. When an alarm probe is alarmed, the monitoring center requires an instant alarm of sound and light, and at the same time, the spotlight or other illumination system of the front end can be automatically turned on; 2) System block diagram: 3) System function: The monitoring system consists of front-end equipment (camera, lens, pan/tilt, protective cover, bracket, decoder, alarm probe, spotlight, etc.) and central control equipment (hard disk recorder, matrix host, monitor, alarm box, video distributor, etc.). The central control device is divided into a hard disk recording system, a matrix control system, and an alarm system according to the function division. The following is a brief introduction of each module function: 1 hard disk recording system main function Currently, a digital hard disk recorder supports up to 32 video inputs; Local monitoring, recording, and playback; Support a variety of screen split display, single-screen round-robin display; video support mobile sensing video, regular video, alarm video and other video recording methods; support multiple screen simultaneous playback in LAN and WAN; The recording data storage time can be set according to the user's needs (the conventional calculation basis of the recording data amount: 150M/hour/way); The clock and camera title can be superimposed on the video window. PTZ lens control (including high-speed ball control, support for shift control and pre-position control); Optional special alarm decoder, can also connect infrared, smoke and other alarm detectors as alarm input devices; The DVR has an electronic map function. The user can draw an electronic map and set an alarm point according to the actual situation. After the alarm, the electronic map automatically pops up to display the alarm position. The user can set a multi-level user password to log in, and different operators can enjoy different permissions to avoid illegal operations. Video data backup; backup video data can be played on any machine through stand-alone playback software. 2 matrix system main function The time, date, operating status and camera title can be displayed on the monitor screen; Supports free switching, program switching, synchronous switching, group switching, and multiple switching modes; Can control constant speed or variable speed pan/tilt/control motorized lens to support high speed ball control; Built-in 16-channel alarm input / 2 channel alarm linkage output, can be linked to video switching after alarm; The alarm output is programmable; Matrix host supports RS-485, RS-422 and RS-232 communication modes 3 alarm system main function Timed disarming (implemented by digital hard disk recorder software); Manually control alarm output such as sirens and spotlights; Alarm linkage video; Display alarm point information through the electronic map of the hard disk recorder; The alarm box is compatible with various types of alarm probes; 4 video distributor role in this monitoring system In the TV monitoring system, the video signal display device, the recording device and the switching device are included, and each camera can only output one video signal. Obviously, this is not enough for the monitoring center, and then the video distributor needs to be added. The video distributor is used to distribute one video signal input into multiple identical video signal outputs, perform voltage amplitude amplification or power amplification on the input video signal as needed, and perform frequency compensation on the video signal transmitted from a long distance. Video distributors have 2 assignments (1 input becomes 2 outputs), 4 assignments (1 input becomes 4 outputs), 8 assignments, etc. The number of inputs is 1, 2, 4, 8 A variety of models can be selected according to actual needs. 4) Monitoring equipment configuration list Front-end monitoring equipment monitoring room monitoring equipment Gun camera Lens protecting mask Bracket 12V/1A regulated power supply digital hard disk recorder monitor Communication conversion interface Matrix host Master keyboard Monitor Dome camera 12V/1A regulated power supply video distributor Integrated camera Ball head (or ordinary head) Decoder alarm box The development of the security industry for decades, regardless of the development of technology, or the demand of the market, is increasingly tending to the industry development, industry solutions! No matter from the front end, or the transmission equipment, or the back-end centralized management, and decoding on the big screen Or the video wall, have got some technical changes, but from analog cameras, to network cameras, to smart cameras, intermediate transmission equipment from ordinary video lines, network cables, fiber optics, wireless, back-end analog matrix, video Dispenser, splitter, upper monitor, then decoding card plus platform software, upper display, and then to the current network digital matrix set storage, remote switching, remote management equal to one, decoding on the TV wall, or large screen display Multi-screen output, multi-screen segmentation display, truly let peers step into a network monitoring era, and then look at the slow heat of 3G monitoring. 220V 25*15Cm Led Neon Flex,Ledvance Neon Flex,Neon Flex Strip Light,Led Neon Flex Light NINGBO SENTU ART AND CRAFT CO.,LTD. , https://www.lightworld-sentu.com
