Security system of security monitoring system

1. Cell perimeter crossing prevention alarm

The perimeter anti-crossing alarm system of the community is designed with an active infrared radiation alarm system for perimeter anti-crossing, which actively detects, locates and alarms the illegal intruders around, so as to inform the security personnel of what happened in the shooting area and prompt them to deal with it. The residential area adopts the way of erecting infrared cameras on the fence and combining infrared shooting for protection. According to the site conditions and Party A's suggestion, the number of cross-shots is at most 50 pairs, and the situation of each alarm point will be displayed on the digital map, and the monitoring camera can point to the problem location for viewing.

2. Closed circuit television monitoring

The main channels and areas of CCTV monitoring system are multiplexed through CCTV monitoring, so as to give linkage alarm when the situation occurs. Use outdoor color omni-directional three-variable cameras, use cameras with different illuminance, and install infrared night vision cameras in different parts. The design system adopts the hard disk video system of alarm linkage video recording as alarm image storage, and adopts large-scale video matrix as central control system.

3. Intercom and all-in-one card (including family anti-theft)

The main purpose of this paper is to effectively manage and control the visitor flow of residential quarters, residential buildings and residents. By setting up the management center machine and the door machine of the residential building to form the peripheral access equipment, designing the indoor machine of residents and selecting the household extension with networking function, the functions of the system can be improved and expanded to meet the needs of different households and save the increased investment due to setting different system functions. The 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 include: building visual intercom, smart home security, community announcement, photo message, home appliance control, lighting control, three-meter inquiry, community service, family assistant and so on. Full Chinese interface, graphic display, touch screen operation locking control, monitoring, He Xuan ringing, doorbell, call post, call center, emergency call, wired and wireless area alarm, MMS sending and receiving, call transfer, caring function, silent and undisturbed, supporting touch screen operation. The one-card part mainly considers practicality, durability and convenience for users. Install active infrared probes for protection at important entrances and exits and stairs in the inner perimeter, and install alarm host in the duty room (monitoring room) of the monitoring center. Once someone enters a place, the probe will automatically sense and trigger an alarm, the host will display the alarm position, and the corresponding searchlight and camera will be linked, and the alarm camera will automatically switch to an alarm camera screen on the host. The computer in the alarm center will pop up the electronic map and record the alarm, prompting the personnel on duty to handle it, which greatly strengthens the security. The alarm prevention system uses active infrared mobile detectors to control important channels and connect them to the alarm center of the management center. When someone enters from an abnormal entrance during non-working hours, the detector will immediately send an alarm signal to the management center, and at the same time start the linkage device and equipment to warn the intruder, so that continuous camera shooting and video recording can be carried out.

An electronic fence was installed on the periphery. Electronic fence is the most advanced perimeter anti-theft alarm system at present, which consists of high-voltage electronic pulse host and front-end detection fence. The high-voltage electronic pulse host generates and receives high-voltage pulse signals, which can generate alarm signals when the front-end detection fence is in the state of touching the net, short circuit and open circuit, and send intrusion signals to the security alarm center; The front-end detection fence is a tangible perimeter composed of rods and metal wires. Electronic fence is an active intrusion prevention fence, which can resist intrusion attempts, repel intruders, delay the invasion time, and not threaten people's life safety. It sends intrusion signals to the monitoring equipment of the security department to ensure that managers can know the situation in the alarm area in time and deal with it quickly. Power supply plays an important role in ensuring the normal operation of the whole closed-circuit monitoring and alarm system. Once the power supply is damaged, the whole system will be paralyzed. System power supply can be divided into centralized power supply and decentralized power supply, and users can choose according to actual needs.

The above is just a typical introduction of security monitoring system. In practical application, there will be different types of schemes, and the security monitoring system scheme will generally be tailored according to the different requirements of users.
