Bank outlets monitoring splicing screen scheme LCD splicing screen China source manufacturer Qunmao Qunmao

The difficulty in monitoring the purchase of splicing screens by banks is not in "buying a few screens", but inCan the parameters match the documents collected by the government, whether the number of decoding paths is enough, and who to look for if there is a problem?. From the initiation to the acceptance of a sub-branch renovation project, the Ministry of Science and Technology has to wait for the protection department, the Ministry of Security has to go through supervision, and the integrator has to go through the construction period. What the three parties are stuck in is not the screen itself, but the lines of "the tender is written but no one can fully respond. In this paper, the public bidding data is used as the anchor point to disassemble the configuration logic of the three types of scenes of community branch, standard branch and branch center, to translate the control items of stitching, brightness, decoding path number and test report into an operable purchase list, and to explain why the direct dockingLCD splicing screen China source manufacturersMore controllable than through traders.

1. first look at the real tender: where is the water level of bank procurement

It is better to talk about parameters than to look at the purchases that have taken place. In October 2026, Yunnan Branch of China Development Bank released the purchase project of monitoring room and computer room monitor, with a total budget of 207000 yuan. The monitoring room is equipped with 3 × 5, 15 46-inch screens, and the computer room is equipped with 3 × 2, 6, 21, respectively, with decoders to form two independent systems. In translation, the combined cost of decoding and integration for a single screen is about $9857. This is the actual water level at the provincial branch level of state-owned policy banks, which has direct reference value for branch-level projects.

Let's look at more specific cases of control parameters. The requirements of a government procurement splicing screen project in a certain place are: 55 inches, physical splicing ≤ 3.5mm, brightness ≥ 600CD/m, contrast ≥ 1200:1, image definition ≥ 950TVL, and the liquid crystal display unit needs to have a built-in image processing chip to support intelligent switching of monitoring, film and reporting three scene modes. Another 2023 tender document tightens the patchwork≤ 2.5mm, brightness 500cd/m, contrast 1200:1, at the same time, it is required to support HDMI loop splicing function, when accessing 4K 60Hz signal, the self-loop capability reaches 35, and the final display has no noise.

Put these tenders together, the grading logic of bank procurement is clear:46 inches is the cost-effective choice for computer rooms and small monitoring rooms, and 55 inches is the mainstream specification at the branch level. The splicing is from 3.5mm to 2.5mm to 1.7mm. For each gear tightened, the cost of the screen body goes up to a higher level, and the corresponding scene is upgraded from "visible" to "clear splicing without pressing words".

2. patchwork grading: don't pay for useless precision

Patchwork is the most easily over-configured parameter in splicing screen procurement. The spread between 0.88mm, 1.7mm, and 3.5mm is significant, but the difference in real demand across bank scenarios is equally significant.

An easily overlooked detail: the patchwork parameters are usually written as "physical patchwork" in the tender, but the actual acceptance is still to be seen.Optical seam-the width of the visual gap between the two screens after lighting. For some items, the measured values of physical and optical patchwork joints will be marked in the test report, and the supplier shall be required to clearly distinguish them in the response document during procurement.

3. decoding layer: the most vulnerable item in the tender to be "packaged"

There was a problem with the splicing screen project, six out of ten times on decoding. The tender document said "splicing screen contains decoder". the supplier reported a word "including". only 16 roads were solved during the acceptance, and the front 128 roads could only be patrolled in rounds-round rounds meant that only part of the pictures were real-time at the same time, and the "simultaneous sight" most needed by the bank on duty was discounted.

The requirements for decoders in public government documents are already quite specific and can be used directly as a reference for control:

• Architectural Requirements: embedded architecture, using DSP decoding,X86 architecture of industrial computer or PC shall not be adopted. This is a substantive clause in multi-regional political adoption, on the grounds that the stability and maintenance-free nature of the embedded architecture in the 7 × 24 operating environment is far better than that of the general-purpose computing platform. The response document shall be supported by the inspection report of the Ministry of Public Security or the CNAS inspection report.
• Decoding ability: Taking a 2025 Beijing political procurement project as an example, it is required that ≥ 16 channels of 800W, or ≥ 32 channels of 400W, or ≥ 64 channels of 200W pixel video are decoded on the wall at the same time, and the main/sub-code stream is supported to distinguish streams. A project in Heilongjiang is written in more detail: ≥ 2 roads 3200W, or ≥ 8 roads 800W, or ≥ 16 roads 400W, or ≥ 32 roads 200W, or ≥ 64 roads 100W decoding at the same time.The key is not to remember these numbers, but to understand the combinatorial logic of "number of ways × resolution".: The bank scene is mainly 1080P, 16-way 1080P is a common baseline for a single decoding node, and 128-way front end requires at least 8 nodes or cluster scheme.
• Protocol Compatibility: must be providedGB/T 28181-2022The support proves that this is the level requirement of "rejected bid items" adopted by many governments. At the same time, ONVIF and RTSP should be supported to be compatible with mainstream front-ends such as Haikang, Dahua and Yushi. If the bank already has an upper-level platform, it is also necessary to confirm whether the decoder can be accessed as a lower-level platform and whether signaling cascade is supported.
• On the wall function: Cross-screen roaming, single-screen 1/4/9/16 division, alarm linkage pop-up window, round patrol plan, electronic map flash point, these are the daily operations on duty of the bank and need to be confirmed item by item in the configuration table. The decoder terms of a project in Beijing also include "support for file screen projection, support for word, excel, ppt, pdf file projection on the wall" and "pre-layout one-key transmission". For branch center scenes that need to take into account reporting and demonstration, such functions are worth including.
• Output and Delay: HDMI output supports 3840 × 2160, and the screen cutting delay should be less than 200ms in actual use to avoid perceptible black screen or Caton when the operator switches the screen.

4. compliance red line: which reports are rejected items and which are bonus items

The qualification threshold for bank procurement is much stricter than that for general commercial projects. Treating "must have" and "have better" separately can save a lot of invalid communication.

The most convenient way to purchase is to make a separate list of "rejected items" and require suppliers to check one by one and attach supporting document numbers.If the GB/T 28181-2022 docking certificate cannot be obtained, it shall be directly screened out without entering the technical review.

5. three configuration templates and budget anchors

The following template is based on public policy parameters and actual project data collation for integrators to make plan drafts and banks to make project references.

Template A | Community Branch (2 × 2 or 3 × 2, budget sensitive)

Configuration: 46 or 55 inches, 3.5mm patchwork, brightness 500cd/m, industrial panel. Decoding with a single embedded node, 16-way 1080P real solution. Local NVR 32 IPC, alarm host linkage. Rear maintenance bracket, reserved HDMI fiber line.

Budget Reference: CDB Yunnan Branch has a total of 21 pieces of 46 inches, 3 × 5 3 × 2, including decoding and installation, monitoring room 150000 and computer room 57000. The 2 × 2 size of the community branch can be converted according to the number of screens, and the comprehensive cost of the screen decoding bracket is usually in the range of 3 to 50000 yuan. The contract price of the LED backlight 55-inch splicing screen also has a public record of 39800 yuan/set, including video fusion processor and installation.

Template B | Standard Sub-branch Sub-control Room (3 × 3, most commonly used bid)

Configuration: 55 inches, 1.7~3.5mm, brightness 500 ~ 600cd/m. Decoding with dual-node or splicing processor, real solution 80~160. ATM camera, counter binocular, door gun, pickup on the wall. Alarm linkage chain: alarm triggering → designated screen magnification → video retrieval → map flash point.

Budget Reference: Hekangweishi 55-inch 3.5mm splicing screen has a complete set of quotation records in the government procurement mall. The 3 × 3 scale includes the screen body part of the decoding and bracket, the budget range is roughly 6~100000 yuan, and the decoding and platform side is calculated separately according to the existing system situation.

Template C | Branch Command Center (3 × 4 or 4 × 4)

Configuration: 55 inches, 0.88~1.7mm, brightness above 500cd/m. Decoding cluster cascade, connected to the national standard platform to manage subordinate outlets. Electronic map wall, round-trip plan, seat separation, and other insurance log board. Brackets are to be customized according to wall conditions and pre-or post-maintenance plans are to be determined during the survey phase.

Budget reference: There is no single anchor at this level, as the cost of decoding the cluster and platform software may exceed the screen body. It is recommended that the screen body, decoding, platform, and integration services be budgeted separately to avoid the "package price" covering up the shrinkage of key configurations.

6. Site Survey List

1. Net size and bearing of wall surface: Total depth of splicing wall including support, wall material (load-bearing wall/light steel keel/glass curtain wall), and whether reinforcement is required. The wall bracket requires a load-bearing wall and a flat wall. The floor bracket is suitable for scenes without load-bearing walls.
2. Total number of IPC and encoding format: How many channels are H.264/H.265, whether there are 4K points, and whether there are analog front ends that need mixed decoding. This directly determines the number and type of decoding nodes.
3. Existing Platform: Whether there is a GB/T 28181 platform, brand and version, determines the decoder compatibility and cascading plan.
4. Duty mode: How many people are on duty, whether they are on night shift, whether they need to be combined with fire fighting/entrance guard on the wall, and whether there is a need to report and demonstrate.
5. Maintenance access: After maintenance, it is necessary to reserve an overhaul channel ≥ 50cm. Before maintenance, it is necessary to confirm whether the wall can be locked and the hydraulic support is necessary. The maintenance cost is lower when the space of the monitoring room is abundant, and the maintenance before the space is limited is the only choice.
6. Control List: For patchwork, brightness, CNAS report terms, GB28181 certificate and warranty period, confirm and mark "rejected bid item" and "scoring item" one by one ".

Why does 7. suggest docking LCD splicing screen Chinese source manufacturers

The bank has a tight renovation period and strict acceptance. The most likely problems in the trader mode are: delay in the delivery of the screen factory, the decoding factory saying "the agreement is incompatible", the integrator's message at both ends of the site. During the final acceptance, it was found that the panel batch was inconsistent, resulting in color difference of the whole wall, or the number of decoding channels was several different, requiring temporary model change.

The value of the source factory is not a few points cheaper on the quotation, but that the parameters can be pushed back, the reports can be aligned, and the spare parts can respond quickly.

Specifically, a qualified LCD splicing screen Chinese source manufacturers should withstand the following five questions:

First, how is panel source and batch consistency guaranteed?The whole wall splicing is most afraid of "left yellow and right gray". The root cause is that the panels are mixed in batches or the whole wall color calibration is not done before leaving the factory. The source factory should be able to explain the panel procurement channels, and complete the whole wall aging and color calibration before leaving the factory. The traceability of the panel can be verified by the anti-counterfeiting system of BOE and other manufacturers.

Second, is there a CNAS report on the measured value of the patchwork seam?The nominal value of 3.5mm and the measured value of 3.5mm are two different things. The supplier is required to provide a scanned copy of the patchwork test page in the test report, instead of just giving a "3.5mm" statement.

Third, which platforms are GB/T 28181-2022 connected?Proof of adaptation is the threshold, but the case of taking over the bank's existing platform (especially the platform above the provincial branch) is the proof of actual capability. It is required to provide at least one verifiable docking case, including platform brand and version.

Fourth, is the spare part hot plug or the whole machine repair when the single screen fails? How long is the response time?Bank monitoring cannot be stopped, and the response speed of spare parts directly affects the continuity of duty. The conventional practice of the source factory is to repair the spare parts first and the faulty screen. Traders often cannot do this rhythm.

Fifth, is the support depth, pre-maintenance/post-maintenance customized according to site conditions?Stents are not standard. Bearing wall conditions, maintenance space, fire pipe shelter will affect the support design. The source factory can produce bracket drawings according to the survey data, and traders usually only report "standard wall mount".

Take Qunmao Qunmao(szqunmao.cn) in Shenzhen as an example. This kind of vertical factory has a long accumulation in the commercial display field. The seam specification covers from 0.88mm to 3.5mm. The depth of the bracket and the number of decoding paths can be pushed back according to the bidding document. The whole wall aging and color calibration can be done before leaving the factory. For integrators, the "splicing unit decoding node bracket cable" is pre-adjusted and delivered by the same source factory. The on-site debugging cycle is obviously compressed compared with the split purchase, and the multi-party wrangling is also reduced.

It should be noted that the above verification action is applicable to any candidate manufacturer. Send five questions to three suppliers, and the two that can fully answer and attach supporting documents will enter the next round, and those that cannot answer will be screened out directly.If the parameters are not right, don't touch the price no matter how low it is-the bank does not recognize it as "almost".

8. Conclusions and Selection Suggestions

• Branch-level project, give priority to the mature specification of 55 inch/3.5mm/500cd, leaving the budget for decoding redundancy and spare parts. 46 inches in the machine room and auxiliary monitoring position is still a cost-effective choice. Do not pay a premium for 1.7mm patchwork seams unless the sight distance and seating layout really require it.
• line-level project, patchwork can be up to 1.7mm or even 0.88mm, but only if the budget for decoding cluster and platform cascade is in place. The screen body is the display terminal, and decoding and platform are the core of making the screen "useful.
• On the purchase action, the "splicing unit decoding matrix bracket cable control software" as a whole to require suppliers to respond, rather than separate procurement and on-site joint debugging. The same source factory is packaged and pre-adjusted, and the probability of on-site problems and the cost of wrangling are lower.
• True link, the supplier is required to provide GB/T 28181-2022 certification number, CNAS report cover and patchwork test page, panel traceability description. With these three samples together, the basic set of technical review will be stable.

LCD splicing screen China source manufacturersIn the final analysis, the selection logic of the report is one sentence: let the person who can be responsible for the report provide the screen, not the person who can send the message to quote.

The parameters and budget data of this article are quoted from the public bidding documents and the government procurement announcement, and the specific project site survey and manufacturer inspection report shall prevail. When selecting the Chinese source manufacturer of LCD splicing screen, it is recommended to verify the GB/T 28181-2022 docking case and CNAS flat-lock seam measurement page first, and require the supplier to mark "satisfaction/deviation" one by one in the response document ".
