The development of the security industry is changing with each passing day, and the security market is constantly putting forward higher requirements for security products. In some security systems with high security requirements, such as prisons, detention centers, traditional video surveillance systems or alarm systems or access control systems appear to be independent and difficult to support in complex scenes. Even if multiple systems are used at the same time, many functions are still stretched, resulting in some security risks. Therefore, the linkage between access control systems, video surveillance systems, and alarm systems is particularly important, and the integration of security products is imperative.
The launch of Tiandiweiye security integrated system solves the hidden security risks that traditional video surveillance systems and access control systems cannot solve, and provides a holistic solution for the rapidly developing security industry. It has been successfully applied to detention centers and prison projects.
1. Detention Center’s Requirements for Security Integration
In order to realize the digital information construction of the public security supervision system and ensure the advanced nature and stability of its security system, the detention center has the following requirements for the integrated security system:
1. Video surveillance function In order to ensure the safety of the cells and ensure that the police officers can see the activities of prisoners in the cells in real time, the system requires cameras to be installed in each cell for monitoring. Due to the special situation of the detention center, every move at the entrance of the prison, corridors, various stair entrances and the surrounding of the courtyard wall needs to be reflected in real time in the central control room. Therefore, cameras need to be installed in these places to realize real-time monitoring. In addition, in order to ensure that the video data can be left for inquiry in the event of an accident, the system requires 24-hour video recording.
2. Access control management function The detention center is a place where prisoners are centrally detained, so access control management has become the top priority in the entire system. In addition to meeting the common functions of civil access control, the access control system required by the detention center must also have the following functions:
1) Interlocking function: Some special places in the detention center are the windows for the inmates in the detention center to contact the outside world, such as the custody and arraignment rooms. These places are the weak links in the security of the detention center. In order to solve the hidden danger of prisoners escaping prisons in these places, it is required that the holding room and the arraignment room can be interlocked to ensure that only one door can be opened at the same time.
2) Anti-submarine control: Because the detention center often detains some criminal suspects without trial, internal and external collusion, collusion and other situations also occur from time to time, which affects judicial justice. Therefore, the detention center requires strict control of all police officers entering and leaving the prison area, and records must be left for each entry and exit. To this end, we especially added the anti-passback function to the access control management function. Anti-passback control is a new technology specially developed for areas with a high degree of security and confidentiality. This function requires all cardholders to swipe their cards in and out in pairs, and the system verifies this. Once a certain card is swiped to enter (exit) the door, it will sneak out (enter) without swiping the card, and the card will be banned by the system the next time the card is swiped in (out) the door.
3) Card-swiping linkage video: The biggest security hazard in the access control system of the detention center is that illegal personnel steal legal cards to commit crimes. Neither traditional access control systems nor video surveillance systems can solve this problem. In addition, in order to prevent someone from stealing someone else’s legal card to commit crimes and to ensure the authenticity of the card swiping record, the system requires that each card swipe can be linked to a video to capture the photo of the card swipe or save the video data when the card is swiped.
3. Surrounding alarm function Due to the particularity of the detention center, video surveillance will have limitations in some specific environments. Therefore, the system requires the installation of some alarm equipment at specific locations inside and outside the detention center, such as infrared detectors, smoke detectors, etc., and can detect the alarm signal in real time in the main control room and respond at the same time.
4. Online patrol function The detention center requires day and night patrols of each door in the prison area. The traditional offline patrol will undoubtedly increase the cost, affect the integrity of the system, and do not have the real-time data. Therefore, the system requires the card reader of each door as a patrol point to realize online patrol. The system software should be able to collect patrol information in real time. Patrol data can generate various reports.
5. Attendance function The electronic attendance function is an indispensable part of modern office, so the system requires the access control point in the office area to realize the attendance function, and the attendance information can be transmitted to the central management host in real time, and can also be temporarily stored in the access control controller. Various reports can be generated from the attendance data as evidence for assessment.
6. Network function Network function is an indispensable function of digital information construction, so the system requires software with a network interface. The managers of the office area can watch the video in the front-end monitoring area through the network; they can access the center through the network to manage the access control of the host, Attendance, patrol data, improve office efficiency.
7. Security control Security control is very important to any system, and it is even more crucial in places like detention centers. The system requires the operating system of the software to set different permissions, so that different managers can access, set and modify the system according to different permissions to ensure system security.
Second, the security integrated system structure and function
In order to meet the requirements of the digital construction of the detention center and ensure the advanced nature and safety of the security system of the detention center, Tiandi Weiye’s integrated security system provides the following equipment: card reader, access control controller, central DVR host, video equipment and alarm control equipment, etc. Several types of hardware devices.
1. Front-end video equipment: Front-end video equipment is a collection tool for video signals, which directly affects whether the central monitoring room can accurately and clearly monitor the surrounding conditions. The front-end equipment in this system is recommended to be equipped with an integrated pinhole camera (used in the prison), a day-night conversion integrated camera (used at a fixed point outside the prison) and an intelligent integrated ball (used at a moving point outside the prison). In addition, in order to ensure the safety of the front-end video equipment, the system provides a variety of protective cover options.
2. Function of alarm equipment: alarm equipment includes alarm host and front-end alarm. The alarm host used in the system adopts the parallel alarm mode, which can collect the alarm signal of the front-end alarm device, and transmit the alarm signal to the DVR host. The DVR host sends commands, and the alarm host makes the corresponding output control.
3. Function of front-end card reader: The front-end card reader is a data acquisition device, and its function is to transmit information such as card number or password to the controller in real time. The card reader adopts RF radio frequency identification technology, the reading frequency is 125KHZ, the receiving frequency is 62.5KHZ, and it supports standard ID cards. The card reader is equipped with a keyboard, which supports the function of password door opening and card plus password function. When the card reader receives a signal, it can prompt in two ways: sound and light. The type of card reader can be configured in two formats: 485 output and Wiegand 26 output.
4. Access controller function: The access controller is the core part of the access control subsystem and the central processor of all card swiping data.Currently available
The controller series for this system include single-door, two-door, four-door and eight-door controllers. The controller can perform door switch control and alarm control according to the information such as the working mode and the cardholder’s permission information downloaded from the upper computer software.
The controller supports automatic conversion between real-time mode and offline mode. In real-time mode, the controller uploads all card swiping information in real time. In offline mode, the controller stores the card swiping information into the controller and uploads it automatically when communication is restored.
The controller can work in one-way card swiping mode and two-way card swiping mode, and supports anti-passback function in two-way card swiping mode. The controller adopts the lower computer authentication mode, all authority processing is completed in the controller, and the controller only transmits the processed data results to the central DVR host. In this working mode, the access control no longer relies too much on the communication function. When the communication fails, the controller can still determine the authority of any card to any door at any time, which fully guarantees the security and stability of the system.
The unique anti-passback function of the controller makes it necessary to keep a record every time you enter and exit, which completely eliminates the hidden danger of criminals sneaking back to commit crimes.
5. Central DVR host function: The central DVR host is the core control part of the system. It not only completes the recording function in the traditional sense, but also undertakes the collection, storage and processing of data in the access control subsystem. The class report is printed out. In addition, the central DVR host can organically combine card swipe signal, video signal and alarm output, making these three systems truly integrated. The central DVR host supports network user access, and multiple network users can access and call relevant data in the database according to their own set permissions to realize network attendance management and network patrol management.
6. System management software function: The central management software can authorize all cardholders in the system, set the opening authority of any cardholder to any door at any time; and can set the working mode of any door at any time, The card swiping data of the access control controller is collected to the background database in real time and processed accordingly.
The central management software organically combines the capture and recording of card data and video signals, so that each subsystem in the entire system can be linked with each other. In addition, the electronic map of the system can monitor the opening and closing status of all doors in the system in real time, and can designate any door to correspond to any channel video, and set the door to capture the card swiping, illegal card capture, designated personnel swiping card capture or designated time period card swiping capture; or Set the door card swipe recording, illegal card recording, designated person swiping card recording or designated time period card swiping recording. When swiping the card to capture the image, the system can automatically call up the original photo of the cardholder for comparison, preventing others from stealing the legal card. The system can link the alarm signal generated by swiping the card with the alarm equipment attached to the host, and make relevant alarm output, such as siren, warning light, or send an alarm signal to the alarm service center.
The attendance management module of the central management software can use the card swiping data of the access control as the attendance record of employees’ entry and exit for attendance management. The attendance software module has strong versatility, can accommodate a variety of personnel files, attendance-related information, and can adapt to different shift management methods; at the same time, the organization can support any number of levels; the function is flexible, and the software can be used in a simple mode, The attendance can be manually calculated directly through the sorted punch-in records, or automated management can be realized by using the abundant automatic attendance calculation functions provided by the system.
The online patrol module of the system can use the card reader in the system as the patrol point, and set different routes and shifts, and the personnel who use the “patrol card” can patrol to realize patrol management.
The system software can have operators and administrators with different rights to ensure the flexibility and security of the operation of each functional module in the system.
3. Composition of a typical detention center project
In the security integration project of a detention center, the detention center has a total of 12 cells, a holding room, an arraignment room, and an office area. The project has the following requirements:
1. Monitoring points and alarm points are distributed on the perimeter of the courtyard wall and in the courtyard, in the corridor of the prison area, in the prison room, and in the office area;
2. There is an access control at each end of the corridor of each prison area, both of which are two-way card swiping and anti-passback control;
3. There are two doors for collection and arraignment, both of which require two-way card swiping, anti-passback control, and need to implement interlocking function;
4. Each door in the office area needs an access control, one-way card swiping;
5. The prison area and the access control office for custody and arraignment need to realize the linkage capture and video recording by swiping the card;
6. All card readers in the detention center can be used as patrol points to realize online patrol;
7. The system needs to realize attendance and online patrol management through the network in the office area.
In response to the above requirements, we have made the following designs:
1. Central management part: The detention center is a place with particularly high security requirements. It not only requires stable operation of the system, but also requires immediate response when an alarm occurs. Therefore, the central DVR host is placed in the central control room of the supervision area, and is responsible for centrally displaying the video signals of the entire supervision area and office area on the screen wall for real-time monitoring, and recording as needed.
The central DVR host is also responsible for the processing of the card swiping data of the access control system. All the data of the access control controllers are uploaded to the central DVR host, and the central DVR host will capture images, video or linkage alarm according to the set linkage conditions.
In addition, the central DVR host is also the central server of the entire system. The remote clients located in the office area can access the system database through the network of the central control room, and conduct network attendance and network patrol management.
2. Alarm host part: The main function of the alarm host is to complete the information exchange between the front-end alarm equipment and the central DVR host. The alarm control host collects the alarm signals of several points at the front end respectively, and then transmits them to the central DVR host in the 485 mode. After receiving the alarm signal, the DVR host will send the processed command to the alarm host, and then the alarm host will output the control signal.
3. Access control part: In the detention center, access control is a vital security equipment, which requires stable operation of the equipment, accurate movements, and real-time data upload.
Therefore, the system has carefully designed the security of all components of the access control part. The entire access control part adopts the working method of card reader control separation. Even if someone maliciously destroys the card reader, it will not affect the door lock. Work. In addition, the access control system is powered by UPS uninterruptible power supply. Even if the mains is interrupted, the access control system will work as usual.
In order to ensure the security of the system, two-way card swiping and anti-passback control are set at the access control at both ends of each prison corridor. In this way, all cardholders must strictly implement the system of swiping cards in and out, blocking the loopholes for criminals to sneak back into the prison to commit crimes.
There are two access controls in the custody and arraignment rooms, one-way card swiping and interlocking, which ensures that the custody and arraignment rooms will not have two doors opened at the same time, ensuring safety.
The access control of the office area is all controlled by one-way card swiping, and it also serves as the attendance point for police officers.
All access control points can be used as patrol points for online patrol.
In order to ensure that every time the card is swiped to open the door, the most realistic record can be left, there is a camera at each access control, which is specially responsible for monitoring the situation of swiping the card to open the door. According to the settings of the host computer software, the DVR host can capture and record the unqualified card swiping and send out an alarm signal. The captured pictures and video data can be directly transferred from the card swiping event record, and the captured pictures can be compared with the original photos of the cardholder, so as to check the real situation when the card is swiped to open the door.
4. Network attendance and patrol part: the system can not only process and query the records of access control, attendance and patrol on the central DVR host, but also the leaders and other managers located in the office area can access the central DVR database through the network, and store the data in the database. The card swiping records are used as the basis for attendance and patrol.
Different managers can set attendance shifts and patrol shifts and routes according to different permissions, or access the database, browse various reports and print them.
5. Security control: In order to ensure the security of the system, the system has set up administrators and operators with different permissions. The administrator has only one person and one password, who can perform all operations on the system and set operator permissions. The number of operators is not limited, and the authority of each operator can be freely set by the administrator in the function options. It not only ensures that legal personnel can operate the system, but also prevents illegal personnel from tampering with the system. The security of the system is guaranteed without affecting the flexibility of the system.
concluding remarks
The integrated security system truly realizes the seamless integration of the traditional monitoring system, alarm system and access control system, so that the functions of each subsystem complement each other. The application of the integrated security system in the detention center provides a standard model project for the majority of security engineering companies, and promotes the development of the security industry.
