Security monitoring system

The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and constitutes an independent and complete system from camera to image display and recording. The security monitoring system can reflect the monitored objects in real time, vividly and truthfully, and can replace manual monitoring for a long time in harsh environments and record it through a video recorder. At the same time, the alarm system equipment will alarm for illegal intrusion. At the same time, the alarm system equipment alarms the illegal intrusion, and the generated alarm signal is input to the alarm host, and the alarm host triggers the monitoring system to record and record.
system introduction:
The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and constitutes an independent and complete system from camera to image display and recording. It can reflect the monitored object in real time, vividly, and truthfully. It not only greatly extends the observation distance of the human eye, but also expands the function of the human eye. It can replace manual long-term surveillance in harsh environments, allowing people to see Everything that actually happened to the monitored site was recorded by a video recorder. At the same time, the alarm system equipment alarms the illegal intrusion, and the generated alarm signal is input to the alarm host, and the alarm host triggers the monitoring system to record and record.
System Components:
Video Security Monitoring System (VSCS) refers to an electronic system or network that uses video detection technology to monitor fortified areas and displays and records on-site images in real time. It mainly includes four parts: front-end equipment, transmission equipment, processing/control equipment and recording/display equipment.
The security system can integrate all the subsystem control equipment in this solution, such as digital video system, anti-theft alarm system, and access control system. On the basis of not affecting the operation of each subsystem, the unified management platform is used to realize integrated interface management, achieve unified operation, unified linkage, unified maintenance, etc., which greatly improves the management efficiency and level of the owner. It can be said that the future integrated development trend of the entire security industry is mainly composed of a security center system, a terminal system and a transmission network.
System parameters:
Image quality level: no less than four of the five image rating levels.
Horizontal resolution: color not less than 400 lines
Gray level: no less than 8
Signal to noise ratio: 40dB
Composite video signal level value: 1VP-P±3dB
security system:
1. Anti-overstepping alarm at the perimeter of the community
The design of the perimeter anti-overstepping alarm system adopts the perimeter anti-overstepping active infrared anti-radiation alarm system, which actively detects, locates and alarms illegal intruders in the surrounding area, and tells the security personnel which pair of shooting areas is happening, and prompts the security personnel to deal with it. . The community adopts a combination of infrared cameras erected on the fence and infrared beams for defense. Combining the site conditions and Party A`s suggestions, the number of shots reached 50 pairs, and the situation of each alarm point will be displayed on the digital map, and the surveillance camera can point to the problem location to view.
2. CCTV surveillance
The main channel of the closed-circuit television monitoring system and the regional closed-circuit television monitoring are multiplexed to alarm when the situation occurs. Outdoor color omnidirectional three-variable cameras are used, cameras with different illuminances are used, and infrared night vision cameras need to be installed in different parts. The design system adopts the hard disk recording system of alarm linkage recording as the alarm image storage, and adopts the large-scale video matrix as the central control system.
3. Intercom and all-in-one card (including home security)
It is mainly aimed at effective management and control of the flow of visitors in residential areas, residential buildings and residents. The peripheral visiting equipment is formed by setting the management center machine and the door machine of the residential building. The indoor machine design of the residents selects the household extension with the networking function. In this way, the functions of the system can be completed and expanded, and the needs of different households can be met and the investment for setting up different system functions can be saved. This extension system can not only meet the visual intercom function, but also realize the function of calling the property management center. The functions that can be realized in the intercom part are: building visual intercom, smart home security, community announcement, photo message, home appliance control, lighting control, three-meter query, community service, home assistant, etc. Full Chinese interface, graphic display, touch screen operation lock control, monitoring, and Hyun ringing, door bell, call door guard, call center, emergency help, wired and wireless zone alarm, MMS sending and receiving, call transfer, care function, mute and do not disturb , Support touch screen operation. The one-card part mainly considers practicality, durability and convenience for users.
System Features:
The remote security monitoring system is based on the digital network as the transmission medium and the core of the network video server. Comprehensive use of digital video processing technology, automatic control, network transmission technology, artificial intelligence and other technologies, not only has the fast video processing capabilities of ordinary security monitoring systems, digital information anti-interference capabilities, and easy to quickly query and record advantages, but also rely on the network , Exploit the advantages of broadband network, and connect the surveillance video center with any point that can be connected to the network through the IP network to achieve the remote, centralized and real-time effect of the ideal closed-circuit surveillance system.
1. The structure is clear and simple: the monitoring host realizes many functions of the video matrix, screen splitter and other equipment in the analog system through the Xiangshi network video centralized monitoring system management software, and realizes the recording function through the computer hard disk, which greatly simplifies the system structure , High integration.
2. Easy management and application: As the digital monitoring system is based on computers and network equipment, most of the system control and management functions are realized by computers, and there is no need to simulate many complicated equipment in the system, which reduces the management work intensity of operation and maintenance personnel.
3. Powerful operation functions: multiple display modes; multi-screen intelligent switch round tour; multiple early warning modes; multiple recording methods such as real-time, timing, alarm trigger, and start and stop at any time; picture capture printing; intelligent fast video playback query, etc. Wait.
4. Simple monitoring and viewing: Because the fully digital network video centralized monitoring mode is based on the characteristics of the network, there is no need to increase equipment investment. The remote or local monitoring center on the network can monitor, record or replay one or more monitoring scene images in real time, authorized The Internet-connected computer can also realize the monitoring function, avoiding the inconvenience and lack of supervision and management caused by the geographical interval.
System layering:
For the security monitoring system, according to the different functions of each part of the system, we divide the entire security monitoring system into seven layers-presentation layer, control layer, processing layer, transmission layer, execution layer, support layer, and acquisition layer. Of course, due to the increasing integration of devices, for some systems, some devices may exist in the system as multiple layers at the same time.
Installation principles:
With the enhancement of security awareness, video surveillance systems are slowly entering the homes of ordinary people. Video surveillance solutions are also emerging in endlessly, so what principles need to be followed when installing a surveillance system? The following 8 surveillance installation principles must first be considered when installing a surveillance system:
