The design design document for the video surveillance system in the residential sub-districts with a flat design map describes this design as the first version of the technical solution, based on the design and construction experience of the provincial and municipal companies hereinafter referred to as the firm's intelligent systems, taking into account benefits and costs in accordance with the principles of advanced practical and reliable rationality。
Design programme。
The control component consists mainly of the master console digital monitoring system mainframe。
The main function of the master console is to correct the video signal distribution of the image signal and to compensate for the alternation of the image signal, the noise loss colour and brightness signals do not produce a significant distortion, to ensure that the original image signal does not cause a significant decrease in the clarity and greyscale of the image signal exported from the camera, etc. The same axis of video that this programme is designed to use depending on the distance of transmission from this building。
Control the passage through the control section number, etc。
Currently, most digital surveillance systems use video base belt transmission。
Radio-frequency or fibre-optic transmission is also used when the camera is far from the control centre。
The transmission focus on the image signal requires that the image signal does not produce a visible signal after passing through the transmission system and is transmitted to the control centre monitor。
The selection of front-end cameras should be considered in terms of practical, easy to install and image effects and the environment, as well as the aesthetic, reliability, security, stability and non-damage of the original building。
The partial transmission of the cable is a clearer system image signal sound message, while the camera is installed on an electric cloud table, which, through control by the controller, allows the cloud-driven camera to rotate horizontally and vertically, thus allowing the camera to cover a larger angle。
In any event, the camera, like the eyes of the entire system, turns its surveillance content into an image whose visual corner can cover the entire monitored area。
In some cases, the size of the sites being monitored is such that, in order to save the number of cameras used to simplify transmission systems and control and display systems, the camera is equipped with a remote, removable focal length multiplier that allows the camera to observe more distant command centres。
The display is made up in part of a television wall of several or more monitors whose function is to display images that will be transmitted。
Part of the camera is the front of the television surveillance system and the eye of the entire system。
It is located at the location of the place under surveillance, so that the quality of the live image signals will affect the quality of the system as a whole。
The transmission component is the system's image signal channel。
The quality of the transmission cable not only affects the quality of the image but also affects the system's ability to resist interference。
The control component is the heart and brain of the entire system, and the video camera component of the video system of the video control system, which is the front of the television surveillance system and is the eye of the entire system, which transforms the content of the surveillance into an image signal, on the monitor of the control centre, on the good or bad part of the camera and on the electrical compatibility of the electron measuring device with its coded cable transmission device, which regulates the composition of the digital closed-circuit television control system of the four systems of the design of the building, which should be described as an interdisciplinary system, with functional variations that could be divided into technical specifications for the design of the fire alarm system, for the design of the electrical design code for the electrical safety of the fire industry, for the design of the satellite design code, for the design of the fire warning signal system, and on the design of the design code, the electrical component of the electrical design code for the electrical safety of the electrical service, which focuses on the transmission of the image signal through the transmission system, and does not produce any significant loss of the signaled signal and brightness signaling system of the satellite feed system, which is to the content of the。
The transmission component is the system's image signal channel。
The quality of the transmission cable not only affects the quality of the image but also affects the system's ability to resist interference。
The control component is the heart and brain of the system and the command centre for the performance of the system function。
The display is made up in part of a television wall of several or more monitors whose function is to display images that will be transmitted。
Part of the camera is the front of the television surveillance system and the eye of the entire system。
It is placed in the location of the place under surveillance so that it can cover the entire area under surveillance。
In some cases, the size of the sites being monitored is such that, in order to save the number of cameras used to simplify the transmission system and the control and display system, the video camera is equipped with a remotely removable complication lens that allows the camera to observe further distances and, at the same time, the camera is placed on an electric cloud table, which, through the control of the controller, can rotate horizontally and vertically, so that the camera can cover a larger angle。
In any case, the camera, like the eyes of the entire system, turns its surveillance content into an image signal and transmits it to the control centre monitor。
The selection of front-end cameras should be considered in terms of practical, easy to install and image effects and the environment, as well as the aesthetic, reliability, security, stability and non-damage of the original building。
Part of the cable transmission is a channel for system image signals, sound signals control signals, etc。
Currently, most digital surveillance systems use video base belt transmission。
Radio-frequency or fibre-optic transmission is also used when the camera is far from the control centre。
The transmission of image signals focuses on the requirement that, after the passing of the image signal through the transmission system, neither the visible noise loss colour nor the brightness signal will produce a significant distortion, that the clarity and the greyness of the image signal exported from the camera from the original image signal will not be significantly reduced, etc., and that, depending on the distance of transmission from the building, the same-axis video lines used in this programme are transmitted。
The control part is the heart and brain of the system and the command centre for the performance of the system function。
The control component consists mainly of the master console digital monitoring system mainframe。
The main function of the general console is video signal distribution image mail
