1. Summary
The design of the museum's network video surveillance system must meet the requirements of modern museums. It must not only focus on the general trend of technological development, but also meet the actual needs of the museum, and also consider the combination with the museum's original security system.
In recent years, many criminals have focused on the museum’s collections of cultural relics. This requires the museum’s security system to prevent intrusion, theft, robbery, sabotage and other criminal acts. It is necessary to create conditions for combating criminal crimes, play an early warning, fight for time for police; delay illegal activities, reduce the scope of damage; and retrospectively and verify afterwards, as far as possible to stop intrusions in the peripheral areas. When combined with the original video surveillance system, the intelligent video surveillance system can provide early warning without being on duty, and record the content of illegal activities. It provides a supplement to the original video surveillance system to the greatest extent, and at the same time reduces the work burden of security personnel, greatly increasing the safety of the museum's security system.
Museums are usually composed of cultural relic storage areas, exhibition areas, leisure service areas, administrative business office areas, etc., and can be classified into restricted areas, protection areas, and surveillance areas according to the security level.
Surveillance area: refers to the area covered between the warning line formed by the perimeter alarm or perimeter fence and the boundary of the protection area.
Protection zone: refers to the area where the public is allowed to enter and exit the protection target.
Restricted area: refers to warehouses, safes, repair rooms and other areas where the public is not allowed to enter and leave the storage and storage of protective objects.
2. System architecture
Use the original analog cameras deployed in each monitoring area to gather the collected live images to the museum's monitoring room through optical fiber or TCP/IP network. These image data will be managed through the monitoring room's management platform and output to the museum through the video matrix The TV wall is provided for monitoring personnel to view, and at the same time, video backup is performed through NVR. The image data collected in the monitoring room of the museum can also be transmitted to the superior management department through the VPN line, and the superior management department can also view the live images and extract storage materials in real time. Form a hierarchical, distributed deployment and centralized management monitoring system.
Intelligent video analysis equipment Trigger and BehaviorWatch obtain video sources from the analog video output terminal connected to the TV wall, and perform video content analysis after encoding. Therefore, no matter whether the original monitoring system adopts an analog or digital solution, it can easily realize the intelligent video analysis function. The people counting instrument iSense can count the number of visitors at each time of the day for the museum and go out various visual charts. AccessWatch can be combined with the museum's original access control system to prevent unauthorized personnel from following staff into the prohibited area.
3. Typical scene
The various functions of the intelligent museum network video surveillance system can be applied to different application scenarios of the museum:
1) Objects left in the tourist area
There are a large number of people visiting the museum every day, and people come and go, and foreign tourists often miss items in the museum. By setting up the "object retention monitoring" mode in areas such as tourist rest areas, an alarm can be triggered immediately after the customer misses an item to remind the monitoring personnel to find the owner.
2) Perimeter monitoring
For the sake of aesthetics, the surrounding environment is generally well greened. The surrounding walls may have more complicated environmental factors, and traditional infrared protection methods cannot effectively monitor them.
By setting the "Object Movement Monitoring" mode, when an object invades the sensitive area, an alarm will be triggered and the intrusion track of the object will be recorded. It can be more effective 24 hours for unattended sensitive areas. At the same time, through Mate's unique SmartScene technology, natural behaviors such as outdoor disturbances are filtered, which greatly reduces the false alarm rate.
3) Protection of restricted areas in the exhibition hall
For the exhibits displayed in the exhibition hall, visitors often turn a blind eye to the warning signs in the hall. Step over the fence to enter the exhibition area, take a group photo with the exhibits, and even touch the exhibits with your hands, causing certain damage to the exhibits. For this situation, in the past, the surveillance personnel called the security personnel to stop the situation after they discovered it through video. This method may have certain omissions, and it is often discovered after the fact that it is too late to fix the situation and the loss has already been caused. We can set up a sensitive area for the exhibition area by setting the "object movement monitoring" mode, and the alarm will be triggered when someone crosses the fence.
4) Anti-theft of exhibits
For the museum, the exhibition of all kinds of paintings must be indispensable, and the safety protection of each painting is also necessary. The original security measures may have various deficiencies. Now through the original video surveillance The system is modified to set up the "object movement monitoring" mode. When the object in the sensitive area is removed, the sensitive area will trigger an alarm, which provides more complete protection for valuable exhibits.
5) People flow statistics
Through the people counting instrument installed at the entrance of each exhibition hall, the real-time people counting data of each exhibition hall is sent back to the server in the monitoring room. It can give a statistical chart of the flow of people in each exhibition hall every day, or give a statistical chart of the total flow of people in all exhibition halls on that day.
4. Program features and advantages
At present, many museums are built on the basis of modern or earlier buildings. They are already cultural relics. There are certain problems in the construction of security construction. Excessive wiring and installation of cameras will cause certain damage to the building itself, and the installation of monitoring The equipment also protects the venues and exhibits. This is a double-edged sword. It is necessary to handle the installation and deployment of equipment, and it is necessary to avoid destroying cultural relics as much as possible.
According to this requirement, the system has designed a specific plan and selected advanced equipment, such as a network camera that supports POE technology, and integrates video cables, audio cables, network cables, wires, and PTZ control cables into one network cable. Use wireless network cameras in the area to minimize the damage caused by wiring installation. For modern museums, the use of advanced equipment is also conducive to the later debugging and maintenance work. The DSNNY intelligent network video surveillance system is fully compatible with network cameras. The system monitors key areas around the clock, reduces labor costs, responds to emergencies in a timely manner, and provides a strong guarantee for museum security.
Therefore, museum security should make full use of modern scientific and technological means, while adopting new technical defense results, strengthen the combination of civil defense, physical defense, and technical defense, and improve the security of cultural relics in the collection under the new situation.
