Smart Community Monitoring Splice Screen Scheme

From community access control and parking linkage, perimeter prevention, property operation data presentation, multi-community networking management, to small screen wall operation minimalism and rehearsal acceptance, the landing judgment of smart community monitoring splicing screen is given.

The most expensive mistake of the smart community monitoring splicing screen scheme is not that the screen is expensive to buy, but "putSplice Screen Scheme of Xueliang ProjectDirectly change the title and send it ".The Xueliang Project is oriented to the comprehensive management system of the county and village governments, and the smart community is oriented to property, streets and residents-the purchasers, operation and maintenance capabilities and core businesses of the two are completely different. Three hard constraints unique to the smart community:Access control, parking and perimeter are the core front end of community security, their alarm must be linked with the video pop-up, rather than just "have a picture" on the big screen ";Property operation data (repair, inspection, payment) and security video on the same screenThe refresh frequency and priority need to be designed separately;Community screen walls are usually only 2 x 2 to 3 x 3The operator is a property security rather than a professional dispatcher, and the operation must be minimal. More crucially, property companies often manage multiple communities,multi-cell convergenceThe requirements are different from the three-level networking logic of the Snow Project. This article is carried out in the order of "community-specific system → access control and parking linkage → perimeter prevention → multi-community convergence → screen number backstepping → small screen wall operation → drill acceptance" and explainsShenzhen Qunmao Display Technology Co., Ltd. as a source manufacturer of LCD splicing screen in ChinaThe actual value of small-scale screen wall customization, non-standard installation and long-term spare parts in the community.

The difference between 1. community and discerning project: different front-end systems and different linkage logic

Both the smart community and the discerning project involve video surveillance and GIS, but the community-specific access control, parking, perimeter and visitor systems determine that the linkage logic of the screen wall is different from that of the government's comprehensive management project.

2. access control and parking linkage: the core screen wall value of the community

The high-frequency event of community security is not "perimeter invasion", but "unfamiliar vehicles enter, visitors are not registered, unit doors are not closed for a long time, and vehicles are parked illegally". If the alarm of these events only stays in the access control system or parking system, the property security needs to look at several screens at the same time to verify. The value of the screen wall is to link the alarm and video to the same field of vision.

In industry practice, entrance guard events can be linked with video storage and map capture. The parking system supports automatic release of fixed vehicles and traffic flow statistics. Alarm events can be linked with large-screen image pop-up window display, sound alarm and automatic tracking of ball machines in the center [citation:3]. In the plan, it shall be confirmed whether the entrance guard and parking system opens the alarm push interface; Whether the decoder or processor of the screen wall supports calling the specified video according to the alarm event; Whether the linkage delay is within the acceptable range.

3. perimeter prevention linkage: "alarm video tracking" of community walls"

After the electronic perimeter of the community (infrared shooting, electronic fence, AI perimeter camera) gives an alarm, the screen wall should not only pop up a text prompt of "perimeter alarm", but should link the video picture corresponding to the defense area and trigger the balling machine to turn to the alarm point.

Intelligent analysis events such as regional intrusion, cross-border detection and wandering detection can be linked with electronic map, real-time picture pop-up window display, voice alarm and intelligent ball machine control [citation:3]. However, it should be clear in the plan whether these linkages are platform functions or screen wall functions, and who is responsible for the coordination. The screen wall is responsible for rendering, and the platform is responsible for alarm logic and video call.

4. Multi-Community Convergence: "One Screen to See Multiple Plans" of Property Headquarters"

Property companies often manage multiple communities, and the headquarters needs to see the key pictures and alarm status of each community. This is different from the "county and village three-level networking" of the discerning project-the property headquarters does not need to read it step by step, but needsGroup round trip alarm priority remote management。

The Qtenboard cloud CMS supports remote equipment monitoring, batch control and OTA update, and can uniformly manage the screen wall status of multiple communities at the headquarters [citation:2]. In the plan, the bandwidth requirements for multi-cell convergence should be confirmed: when the headquarters reads multiple videos at the same time, whether the exit bandwidth is sufficient; Whether the round trip and the alarm pop-up window follow the same link.

5. screen number reverse: community screen wall is usually very small, according to the "core picture" choice

The screen wall of the community monitoring center is usually small. Taking a 55-inch single screen as an example, a total of 4 screens of 2 × 2 are the starting point for many communities, and a total of 9 screens of 3 × 3 can already cover more complex needs. The number of screens is pushed back by the "core picture number" instead of "large, medium and small.

The layout of a 2 × 2 screen wall in a typical community is suggested as follows: one screen is used as a constant display at the entrance and exit (the gate of personnel gate, vehicle gate is divided into two parts each), one screen is used as a round patrol in the key perimeter defense area (divided into four parts), one screen is used as a round patrol in the parking area and unit gate, and one screen is used as an alarm pop-up window and operation area. If the community has more than 4 entrances or longer perimeter, 3 x 3 can be more leisurely distribution screen. The community does not need to reserve a large area of the main screen area for the "GIS map"-property security is more concerned about "whether there are people at the door and whether cars come in" than the global map.

6. small screen wall operation is very simple: property security is not a professional dispatcher

The operator of the community monitoring room is usually the property security, and may be in charge of the door post, patrol and charge. The operation logic of the screen wall must be simpler than that of the government command center.

Community screen wall should not be designed to require multi-step menu, password switching, complex plan operation."The alarm pops up, the picture can be seen clearly, and one key can be restored", is the community screen wall operation design all requirements.

7. Site Conditions and Installation: Space Constraints in Community Monitoring Rooms

The community monitoring room is often not a specially designed computer room, but may be the corner of the property office, the cubicle next to the gate post, and the distribution room next to the basement. The constraints of site conditions on screen wall installation are more obvious than that of government projects.

8. budget trade-offs and source manufacturer value

Community project budgets are usually controlled by the property or developer and are tighter than government projects. Advice on order of trade-offs:First, the constant readability of entrances and exits and perimeters (the core of community security), then the alarm linkage (the entrance guard parking perimeter can pop up), then the operation of the small screen wall is very simple, and finally the complex function of splicing upgrade and multi-cell convergence is considered. The community does not need to pay a premium for the “GIS Single-Map Main Display Area” or the “Three-View Conference Room.”

9. drill acceptance: run "vehicle abnormality → entrance guard linkage → perimeter alarm → headquarters check"

10. common mistakes

• Myth 1: copy the discerning project plan. The core of the community is the access control parking perimeter linkage and property operation, not the three-level networking and grid scheduling. Screen wall scale, linkage logic, operation design are different.
• Misunderstanding 2: The community screen wall is equipped with more than 4 × 4. Community monitoring room space is limited, the operator part-time, too many screens but increase the burden. 2 x 2 to 3 x 3 is usually sufficient, press the core screen to push back.
• Misunderstanding three: only focus on video surveillance, ignoring the access control parking perimeter. The high-frequency events of community security are abnormal vehicles and abnormal entrance guard. The value of the screen wall lies in "the alarm can be played and the video can be seen", not "the video wheel patrol looks good".
• Myth 4: Take a GIS map as the main screen area. Property security is more concerned about entrances and exits and perimeters, and the global map is not the core content of the community screen wall.
• Myth 5: Ignoring the demand for multi-cell convergence. When a property company manages multiple communities, the headquarters needs to see the status and alarm of each community. A remote management interface shall be reserved for the screen wall scheme.
• Misunderstanding six: the community monitoring room directly wall hanging. Community wall conditions often do not support wall hanging, floor brackets or front maintenance programs are more secure.
