Safe, elegant, warm environment is to improve every hotel guest accommodation at least criterion, and often in order to ensure the safety of the hotel according to their own situation, to install a closed-circuit television monitoring system is essential, and its distribution of the front point is mainly on some important protection goals or is the main channel other places, security personnel can monitor the observed in these places, hotel intelligent control system of closed-circuit television monitoring system is the most important part of a comprehensive security system, full attention must be paid to.
A system design, image quality index: 1, according to the five level of damage assessment, image quality should not be less than 4; 2, the image gray level is not less than 8; 3, the level of image resolution and color system of not less than 480 lines; 4, each video signal at the input level of the monitor value should be 1Vpp soil 3dB; 5, in the low illumination system is used, the monitor screen should reach the available image, not less than 25dB ratio of signal to noise.
Each part of the system signal-to-noise ratio index distribution should be: Camera > 48dB > 42dB; transmission part; monitoring section > 38dB; specific requirements of the remaining indicators are in line with national and industry standards and owners; should additional information system and video display screen, including the date, time, number, camera camera location information.
Two, system functions: the function of real-time monitoring; distributed in the building lobby, camera, parking lot, elevator entrance hall, corridor, elevator, etc. around the building can complete the real-time monitoring function of these parts; digital video; video signal input to a front camera input disk recorder the monitoring center, control hard disk video recorder, recording the image. The end of the alarm monitoring center, linkage system will control the DVR immediately recorded image video, and ensure the coherence and integrity; DVR image recording speed is adjustable, customers can set up their own image of the video frames can be carried out in 16 way video and video, can realize manual recording, ordinary time recording, video loop the input video; each of the hard disk video recorder with 120G hard disk 4, a total of 480G, according to the average per hour road occupation of 100M capacity calculation, data storage time recorder for more than 13 days.
Remote monitor / control function: through the LAN DVR network interface access to the building, each point on the network by installing special software and authorized to enter the system, watch the real-time image and the image recorded by the camera, PTZ software for front-end or integrated intelligent ball down, focusing and adjust the aperture and other operations.
Three, system design: closed-circuit television monitoring system is mainly in the hotel lobby, elevator hall, room corridor, elevator etc. set up front camera, to ensure strict precautions on the part of the hotel, while leaving enough interface in the center of equipment, to ensure the performance of the system expansion; the system only 32 front-end equipment, belonging to the small the monitoring system, because now the hard disk video recorder function is enhanced, so the system center of main equipment use only two sets of the hard disk video recorder, without the use of video matrix and monitors and other equipment, each hard disk like machine with a 17 inch display one, 1, 4, 9 can, 16 screen display image so, the personnel on duty in peacetime can fully monitor, just call the single picture can be needed on the key monitoring; system can control the front Camera DVR The image switching, PTZ camera movements, and alarm security / Chefang function.
The hard disk recorder has the function of front-end camera mobile detection and alarm, that is, there are multiple areas in the picture sent to the front end camera. When there are people walking around or moving objects in these areas, they will generate alarm signals, prompting the duty personnel to notice and automatically start the road video. The hard disk video recorder has a network interface, which allows an authorized terminal on the LAN to look at a real time image or video, and can also directly control the moving point of the front end.
Four, the system stability and reliability of equipment selection: closed-circuit television monitoring system above all, if the accident occurred because the fault system leads to the personnel on duty can not see or no video data, then the system is completely lost its due role, become a decoration. The stability of the whole system is based on the quality of the equipment and cable. Therefore, we take full consideration of the price factors on the basis of the stable performance of the equipment, and try to choose the equipment with high cost performance.
