The current owners generally have sufficient attention and clear requirements for the security of the community.A relatively complete community security system should be
Surface, practicality, and advanced are the design principles. It does not pursue the highest-grade equipment, but emphasizes the comprehensiveness and completeness of functions.Easy to use, for the future
There is room for expansion, and at the same time, make full use of the existing equipment functions to develop additional service projects, and provide future
The owner provides multiple services.
The following is a comprehensive introduction to the functions of the subsystems in the system:
1. Intercom system
The community building intercom system is designed for the management characteristics of distributed residential communities, such as multi-channel internal communication, two-way
Call intercom, resident alarm, anti-theft and disaster prevention alarm, etc., to promote simple visitor door opening to the multi-functional comprehensive management level, which is a great improvement
District safety management and convenience for residents play a positive role.
The intercom system is a mature application system. There are many products with similar functions in different grades on the market. At present, the main products of this system are
There are two major types:
(1) Visual (or non-visual) intercom system, mainly used for visitor identification and access control.
(2) Multifunctional intercom system, in addition to realizing identity confirmation and access control; it can also realize emergency help, infrared alarm, smoke
Home security functions such as alarm.
Both types of products can be networked and monitored and managed by the control center of the community or building.
It is generally reasonable to make choices based on grades and needs. The developer is responsible for investing in the most basic part of the system, mainly public communication.
For the transmission network and control center, there are interfaces on the user side. The specific user side equipment will be selected by future owners, but the entire system needs to be considered.
Taking into account the diversity of future owners’ needs, the system should be scalable.
It is worth mentioning that for large communities, special attention should be paid to equipment selection, because of a huge intercom/security network.
The performance requirements of the equipment will be higher.
2. Vehicle management system
When the user drives into the community parking lot or underground garage, only the induction type1C card is shown in front of the card reader, and the recognition can be completed instantly
Work, after the identity is authenticated, automatically control the raising of the gate machine, release the vehicle, and record it in the property database to realize the management of the original person.
Save expenses and improve management level.
This IC card can be divided into three types:
(1) Perennial cards used by car owners who have purchased parking spaces;
(2) Monthly rental card for renting parking spaces;
(3) Time-based billing card used by temporary visitors.
On the basis of completing the above-mentioned garage access control functions, some equipment and software are appropriately added to realize one card corresponding to the type of vehicle entering and exiting.
, License plate comparison, dynamic display of empty parking spaces in the library, etc., so as to achieve complete vehicle management.
3. Electronic Patrol System
Set up electronic patrol points in key areas of the community, each patrol point has pre-embedded patrol “buttons”, and the personnel on duty carry portable electronic patrols
Hold the patrol “buttons” to be read regularly at each patrol point.The patrol status of the staff on duty is transmitted to the property through the information communicator via the network bus
The computer in the management center can realize the on-duty assessment of the on-duty personnel and guarantee the on-duty personnel’s
Life safety, to achieve an effective combination of civil air defense and technical defense.
The location and number of specific patrol locations need to be negotiated and determined with the property management department.The system can compensate for technical means and personnel quality
The above defects ensure the property management level of the community.
4. Perimeter anti-theft alarm system
Modern society is progressing and the economy is prospering, but social security problems are becoming more and more serious. Various thefts and robberies have been heard every day.
Life and property are seriously threatened, so the perimeter anti-theft alarm system is the main method to isolate the community from the outside world, commonly known as “electronic fence”
.The combination of perimeter anti-theft alarm and camera monitoring system and patrol system makes a relatively closed residential area a safe
Harbor.
Existing technical means can use active infrared sensors.Passive infrared sensor, Doppler radar, pressure sensor or vibration sensor
Detecting means such as detectors, through centralized controller, execution unit, alarm unit, etc. constitute the system.Combined with the prevention level and characteristics of the community,
Active infrared sensors are often used. According to our implementation experience, the use of manual intermediary can be used on the basis of the lowest cost.
Effectively solve the contradiction between false positives and false negatives. According to the geographical environment of the community or building, active infrared dual
Detectors, bright lights and cameras. Block these locations within the set time zone.When illegal people enter the security zone
At the time, the security center terminal will get the alarm signal, and at the same time, the CCTV system will be linked to send the image of the camera in the alarm area to the monitor
On the screen and recorded on the video recorder. When the sensitivity of the system is high (reduce the false negative rate), manually judge the nature of the alarm through the image (
Reduce the loss of false positives), and determine the means of handling.
5. Closed-circuit monitoring system
The security system must be reliable, fast, and comprehensive.The TV monitoring system is an important part of the security system, it has the right
Real-time central monitoring of important locations such as main entrances and exits, important public places, parking lot entrances and exits, and the population halls of each building in the small area
, Real-time recording, with the characteristics of post-inquiry.
Set up TV surveillance camera devices in the main population and important places of the community, and transmit the surveillance pictures to the duty room. The duty personnel can
The monitoring angle of the camera can be controlled at any time to track and monitor suspicious persons.
The main function of the closed-circuit television monitoring system is to assist the security system in real-time monitoring of the live situation of the community.The system mainly consists of black and white photography
The camera video matrix is composed of a host, a monitor, and a long-term video recorder.There are no fixed cameras and cameras with PTZ at the entrance and exit of the community
Machine monitoring, the exit of the parking garage has a fixed camera to monitor its main passage (the specific number will be determined in conjunction with the specific situation).Another in the community
The center of the square is also equipped with a camera with a PTZ for surveillance. When an alarm occurs in the security system, the camera will be rotated to draw the alarm area.
The face is cut into the monitor, and the video recorder is linked to record the live situation.
