Smart community, in a broad sense, is the use of modern building technology and modern high-tech computer, communications, control and other high-tech, integrated property management, security, communications and other systems, and through the communication network to connect the property management office, to provide residential residents A safe, comfortable and convenient modern living environment. In a narrow sense, it includes home automation systems, home information service systems, property management systems, and community public service systems.
Seven Smart Security Technology
1. Closed-circuit monitoring system The closed-circuit monitoring system is one of the monitoring and information means of the security status of the work area. Combined with the internal intercom system and the public broadcasting system, it can reduce the work intensity of management personnel and improve the management quality and management efficiency. The closed-circuit monitoring system is a powerful auxiliary tool for modern security. It transmits video images or dangerous signals from various sites within the site to the main control center and sub-management room. The on-duty management personnel can objectively analyze the scenes without visiting the site. Regional centralized surveillance, found that the situation was unified and mobilized, leading to evacuation, saving a large number of patrolling personnel, a small number of people can avoid many human factors, to ensure the implementation of the program properly handled in the shortest time.
Second, the intrusion alarm system The intrusion alarm system is generally composed of a detector, an alarm controller, a linkage controller, an analog display screen, and a searchlight. Most intrusion alarm systems use line detectors. Line detectors use two-way/four-way active infrared detectors to form an illegal crossing alarm system. The system adopts fuzzy control technology to effectively avoid the influence of small animals, sundries, and snowstorms on the detection and alarm, and at the same time guarantees instant warning of illegal overturning of larger objects and people. When the detector detects the intrusion signal, it will alarm the residential property alarm center, and the alarm center linkage controller will open the relevant area searchlight, issue an alarm siren, start the video recorder, and simulate the electronic screen to dynamically display the alarm area. The alarm center monitoring computer can pop up the electronic map.
Third, access control system Access control system is an important channel for intelligent residential management. The gated system can control the access of personnel, and can also control the behavior of personnel in buildings and sensitive areas. Install control devices such as card readers, fingerprint readers, and password keypads at building entrances, elevators, etc. In order for a tenant to enter, he must have a card or enter the correct password, or press a dedicated finger to be approved. The access control system can effectively manage the opening and closing of doors to ensure that authorized personnel can freely access and restrict the entry of unauthorized personnel.
Fourth, the electronic patrol system patrol system is a means for managers to inspect whether the patroller arrived at the appointed place by the patrol route at the appointed time. The patrol system helps managers understand the performance of patrollers, and managers can change patrol routes at any time to meet the needs of different occasions. Patrol system is divided into wired and wireless:
The wireless patrol system consists of information buttons, patrolling handheld recorders, downloaders, computers and management software. Information buttons are installed on the site, such as in the vicinity of the doorways of residential buildings, garages, and other major roads, etc.; patrol handheld recorders are carried by patrolling personnel on duty; downloaders are components that connect hand-held recorders and computers for information exchange. It is set in the computer room. The wireless patrol system has a simple installation, does not require a dedicated computer, and the system is very convenient for expansion, modification, and management.
The cable patrol system is a patrolling officer sending a signal to the management computer at the specified time and place on the specified patrol route to indicate normality. If the signal is not sent to the management computer within the specified time, or if it is not in accordance with regulations The signal appears in the order, and the system will consider it as abnormal. In this way, the patrol personnel will soon be aware of problems or dangers.
5. The intelligent residential security system is mainly based on home burglar alarm systems. It consists of a security center management host, home alarms, various types of sensors and transmission lines. The entry points are mainly doors and windows. The sensors are deployed in important locations and areas of the family, allowing the owners to live in a safer and more comfortable environment. All kinds of sensors are introduced as follows: window magnetic, magnetic switch, gas leak alarm, smoke alarm, emergency button and other security systems are used in the home, in each home owner's home equipped with infrared sensors, magnetic window magnetic switch, Smoke detectors, emergency alarm buttons, etc. Each entrance to the unit is equipped with a host computer at the entrance, and a set of management hosts is set up at the security center. When a guest visits, press the outdoor button or the room number of the respondent, and the room indoor unit will send a ringing tone. At the same time, the screen of the indoor unit will automatically turn on, displaying the image of the visitor and the outdoor situation. The owner and the guest will Talk about the call, confirm the identity through the indoor extension of the unlock key remote control electric gate to allow guests to enter, the guests enter the gate, the door automatically closed.
In addition, through cell networking, centralized security alarm management can be implemented for all users who install the home security system in the entire cell. Each home security system can send alarm signals to the management center through the bus. The management personnel can confirm the location and type of the alarm. The computer also displays some information related to the households so that the security personnel can promptly and correctly answer the alarms. deal with.
VI. Perimeter Defense System The perimeter fence system is mainly used to monitor the surrounding conditions of buildings and prevent illegal intrusion. It is the first line of defense for the anti-theft alarm system and is also a very important line of defense.
Perimeter protection sensors can be detected as soon as the intruder enters the zone and alert him before he or she approaches the protected person and protected property. An effective outdoor security system can be used as a return on equipment investment by reducing the risk of theft and reducing damage and personal injury.
7. Video Intercom System The traditional analog video intercom system consists of a management center, a visible outdoor host, and a visual indoor extension power supply. Three-way calls can be achieved, building intercom, image monitoring, integrated alarm, unlock the door, alarm memory, integrated management of the center. The system adopts 485 cabling transmission method. According to different requirements, it can be connected to magnetic, infrared, smoke, gas probes and computer centers, workstations and "110" alarm center, implementing intelligent community management.
The digital network intercom system adopts network signal transmission. In addition to all the functions of the above analog video intercom system, it also has free video calls (viop) through the network, calls to the pstn telephone (or regular telephone), and security alarms. , E-mail, access to weather forecasts, community information announcements and other information release, multimedia advertising value-added services and other functions.
Intelligent Community Security FAQ
Community intelligence will always appear in one or another kind of problems during its use and operation. These include design flaws, problems with installation, and improper use and other factors. The following is a summary of common problems and solutions!
æ··ä¹± Mislabelled or unmarked lines in the integrated cabling process. All system cabling is incorporated into the cabling. The wiring system project is the longest construction cycle in the entire project, and the largest amount of manpower investment. It is also the most important part of the entire system. In the construction of the modern community, it is mostly a concealed project and they are all permanent links.
In the wiring, there is often a phenomenon that the line marking is disordered or even not marked, leaving a lot of trouble for the installation, debugging, and maintenance of the project. The line is not marked when the equipment is installed and debugged. It is necessary to input the manpower twice to measure the line after the completion of the project. If the label is still not marked or even unmarked, it will cause difficulties for the maintenance work. Therefore, each line must be marked clearly in the wiring process. This will not only save installation cost, but also facilitate installation and debugging of the project.
The reasons for this kind of site are mostly caused by the insufficiency of engineering management. The solution is to provide all-round training for construction personnel and strict requirements in construction.
æ— Outdoor wiring terminations without waterproofing and sun protection measures need to have outdoor waterproofing and sun protection measures to delay the system's service life and system stability.
Line terminations are susceptible to aging due to non-water-proof sun protection measures, resulting in system instability and the like, resulting in high rates of return repairs and even causing system defects in case of maintenance failures.
Solution:
1, in the indoor termination of the line as much as possible in the indoor termination, even if the extension of some lines, the bus system can be hand-in-hand wiring;
2. The outdoor termination part can be sealed to delay the aging. The disadvantage of this method is that it is inconvenient in the system maintenance and line maintenance. If the line needs to be dismantled, it must be resealed.
3, can increase the outdoor wiring box, all the outdoor termination of the line into the wiring box termination, this method not only solves the problem of outdoor termination waterproof sunscreen, and easy maintenance.
â—‡ Intercom host installation height is not suitable for most intercom host installations are based on the bottom of the host 1.5 meters away from the ground, but because the host height of all manufacturers are different, so the height of the specific installation must be based on the entity, it should be According to the height of the camera as a standard, in order to make the indoor extension more clearly see visitors. Some cell units have a ladder in front of the door. This results in the height of the station where the visitor is not the height of the bottom door frame of the unit door, but the next or even two steps. Therefore, the height of the host installation site must be fully considered. Happening.
Intercom mainframe is not rainproof. Some hosts are installed on the wall of the unit door. The host may be exposed due to the small canopy of the building. This may cause the host to expose to the sun and rain, thereby affecting the stability and use of the equipment. life.
Solution:
1. The door machine can be installed on the unit door so that it will not cause the main unit to burst out of the canopy;
2. If the host must be installed on the wall, it can increase the size of the canopy or add protective devices to the host.
â—‡ In the closed-circuit monitoring system, the same pipeline and circuit in the closed circuit monitoring and wiring will often appear parallel to the strong electric circuit or even the same pipeline phenomenon, this phenomenon is mainly caused by poor design and unreasonable, but also It is not that we can arrange any wiring in this case, as long as we strive to strive for in the construction, but the stability and reliability of the system will be improved. Otherwise, the monitor image will be seriously distorted.
Solution:
1, the use of better shielding or even double shielded cable;
2. It is possible to have multiple line tubes even in the same pipeline, and do not wire with strong circuits in the same line tube;
3, especially in the elevator wiring, because the elevator is a strong power, greater impact, we must strive for distance from the strong circuit, even if it is a centimeter will make the image signal several times better;
4, increase anti-interference equipment.
暴露 The monitoring of the privacy community in the closed-circuit monitoring system can easily reveal the privacy of the occupants. The owner’s privacy will be unknowingly exposed. If the video data is unreasonably transferred, it will cause great harm to the owner. There may even be lawsuits.
Solution:
1. Install a suitable location. The cameras in the community should be installed mainly in public places such as squares and traffic arteries;
2, the camera should avoid facing the direction of the house.
åœè½¦åœº The location of the parking card reader is not suitable for installation. Currently, there are two kinds of readers in the market: id and ic. The readable distance ranges from 10 centimeters to 10 meters. For the medium and long distance readers, the distance is far from the card reader, so Drivers do not take the initiative to take the card, as long as the card in the car waiting for the car through the card reader is automatically read the card, and for the 10 cm close proximity card reader, the driver must roll down the window and get out of the card reader Before you brush it, it is the reader that collects the data, so the reader must be installed in a position that is easily accessible to the driver. In some quarters, due to site conditions, vehicle readers cannot turn in and out. Turning in and out cannot read cards properly, so that the driver must walk out of the car to swipe the card, causing inconvenience to the owner. Solution: Fully inspect the site and choose the right location to install the parking management equipment.
周 Perimeter protection system is installed as normally closed alarm The general alarm can be divided into two types. One is the normally open alarm and the other is the normally closed alarm. However, the normally closed alarm is not suitable for the perimeter protection system. Because the normally closed mode alarm is in the normal state under normal open conditions, and the signal line is disconnected due to some factors, the system still prompts the normal state, and will not alarm, and the normally open mode alarm only needs to disconnect the line. Will alarm, to achieve the purpose of automatic detection of the system, regardless of the choice of which alarm has its advantages and disadvantages, but the line circuit is much greater than the chance of short circuit, so I suggest that the perimeter of the regular alarm system alarm system is more appropriate.
The electronic patrol route is not suitable for electronic patrols, including cable patrols and wireless patrols. The wireless electronic patrol has many advantages such as easy installation, simple maintenance, and stable system. It has gradually replaced the traditional cable patrol system and has caused poor patrols. More lines will distract the patrolling staff. It may make it necessary for patrolling personnel to enter the lawn to reach the patrol point, especially for the patrol personnel in rain and snow.
Solution:
1. The patrol line should be designed and installed on the s-type line so that there is no dead space;
2. The patrolling point should be installed at a place easily accessible by patrol personnel, usually at the roadside, in front of the unit doorway, etc.
â—‡ Home-networking alarm system Infrared detectors facing the window The home-networking alarm system brings security to all households, but more false alarms will make the household extremely annoying. The level of false positives is not only related to the selection of the root product, but also has a close relationship with the installation of the equipment. Most of the anti-theft devices installed in the home are infrared detectors. If the installation of infrared detectors faces the windows and the electrical appliances with large variations in temperature, there will be more false alarms. The most common problem in installation is that the effective range of the detector reaches the outside of the window, so that outdoor environmental factors cause more false alarms.
Solution: Make the detector toward a stable indoor environment.
In the process of installation and debugging, there will always be such problems, but we should strive to reduce the occurrence of these problems, so as to avoid more problems and difficulties in the future use and maintenance.
