Dahua's exploration and practice of integration of security systems

The integrated implementation of the security system has always been one of the major responsibilities of the contractor. With the diversification of security products and the differentiation of functions, the game between multiple vendors has brought new challenges to on-site construction. . The time and labor costs of the construction plan, the high requirements of construction quality, and the risk control of the commissioning all test the strength of the engineering firm and are also affecting the nerves of the manufacturer's product design.

First, the system's integration needs originally come from the user's business needs

The original design of the product is based on the unity of the main direction of the professional development, in order to achieve the function of a business subsystem, it requires multiple products with the joint adjustment, and even need to complete the docking work through their respective secondary development interface, During this period, the engineering firm became a glue between the user and the manufacturer. If it hits a product with a relatively closed design, the whole work will be deadlocked.

In the security system, the earliest request from the user was the perimeter alarm, access control linkage, and other requirements. He requested that the system be a central business platform for the system, not only providing video equipment access, preview, storage, but also with the alarm host and access control system. The all-around linkage mechanism achieves a true “leadership to the whole body” rather than a relatively isolated business subsystem that needs to be artificially linked. In order to realize the compatibility of the monitoring platform with multiple manufacturers of alarm hosts and access control, platform manufacturers will adjust their design of the monitoring platform, increase the design of the equipment access layer, and improve the business process design, but also give the original platform The factors that brought instability, including the iterative release of products, also have different degrees of influence.

From the current trend, some mainstream security vendors have also found a compromise solution. They have designed the concept of a "gateway", have specialized device gateways for accessing multiple vendors' devices, and also have platforms for implementing heterogeneous design system interoperability. Gateways, gateways of this nature, in essence, through the design of the hardware isolation layer, cleverly solve the integration problem of the two types of products, present a complete experience to the user on the business system, and can avoid the design. Forced strong coupling design.

Second, the public security industry has come to the front in the exploration of integrated applications.

The public security industry has always been at the forefront in the field of security. The construction of a safe city in the country has greatly promoted the rapid development of the entire security industry. Various new technologies, new products and new programs have appeared frequently in the public security system. It also promoted the designation of industry technical standards, especially the GB/T28181 standard protocol, which has a decisive influence in the security field and provided reliable technical specifications for equipment access and connection of heterogeneous platforms in other industries.

At the same time, in the field of public security services, requirements have also been constantly put forward, such as the integration of video and picture elements into case management, integration with existing video surveillance systems, support for the registration of cases (events), rights management of cases (events), and provision of The docking interface of the police comprehensive platform can quickly synchronize the cases to the video platform, support the sharing of cases, serialization of cases, and the export of video investigation reports. The realization of these functions is not a product that can be independently assumed. In previous solutions, for example, a certain company provided a video enrichment algorithm in the background, which could extract and consolidate a large number of stored videos. Companies familiar with public security services provided business software to support the public security business, plus independent construction. Video surveillance systems, the inevitable need for integration among multiple vendors, can bring a unified experience to end users. The challenges faced here are not only technical requirements, but also product cooperation and manufacturer cooperation. Communication is the biggest cost. .

If there is a company that can integrate multiple products directly on the solution and provide a complete solution, it will certainly bring convenience to the implementation of the project, and the maintenance in the later period will also be simpler, but it will also test the design of the system integration capabilities of the manufacturers. This is not simple is to do a 1 +1 addition, the following figure is a smart battle platform topology introduced by a manufacturer at a security exhibition, from which can also be seen as, manufacturers have not met a single offering, but more from The idea of ​​an overall solution for the industry provides an integrated system.

Third, security vendors in the monitoring platform product hardware and software integration design exploration is worth encouraging micro innovation

In the second half of 2013, we also saw some unique integration ideas of other security companies. The successful video surveillance platform is integrated in the design of hardware and software, which brings a new leap in performance, making people feel refreshed and also gives The dying sales of video surveillance platform software has brought new growth points.

The first manufacturer to emerge from this product is not the first one proposed from the concept of product prototype, but it is driving the security company to move forward with this design idea, so that in early 14th, several other major manufacturers There has also been a similar integrated design of monitoring platform products.

So, let's review the first successful case. The following third-party agencies' observations

"First of all, this product is designed with a 3U chassis, uses a Linux operating system and a professional custom hardware platform, supports 4 core CPUs, and comes standard with 4G memory (up to 16G). This machine supports the installation of LCD panels with panel locks. It can not only protect stored data from malicious damage, but also can display system information and configure platform parameters through the LCD screen.Open the LCD panel, you can see the upper left side of the front panel is the power button and status indicator; The data interface is connected to the LCD screen. On the right are two USB interfaces that facilitate the insertion and removal of USB devices such as the mouse. The main part is a pull-out design disk tray that supports 16 SATA0, SATA1 standard hard disks (maximum single hard disk The capacity is 4TB, one of which is used to store the database and can also be expanded via IP SAN).

Then go to the rear panel, see the interface design is simple, the bottom from left to right are hot-swappable 100V ~ 240V wide voltage power supply, 4 100/1000Mbps adaptive Ethernet port (supports redundancy, network port balance binding Fixed or independent Gigabit Ethernet port application), VGA local output jack, 2 USB ports, 1 e-SATA expansion jack, 2 HDMI HD output ports and 4 green terminals. “

The above is a description of the hardware, then the software and hardware integration design, can bring much improvement in software performance? Look at the following performance description:

“The maximum number of devices supported by a single platform device is 500 (maximum video capacity is 5000 channels); the total network switching capacity is 1800MB/S; any 500-channel D1@2Mbps bitstream/250-channel 720P@4Mbps is supported. Code Stream/125-channel 1080P@8Mbps Streaming Network Video Switching Output; concurrently supports 500-channel D1@2Mbps stream forwarding and storage concurrent processing; can process 1000 simultaneous online requests (up to 10,000 registrations).

The efficient processing performance makes the software based on this hardware platform have been given full play in the three key performances of access volume, streaming media forwarding, and storage. “

This micro innovation, the market sales to give the best affirmation, from the sales data released by the manufacturers to see, 13 years and a half to reach a few thousand sales, which is indeed a big success. As a result, other vendors are also upgrading on a larger disk, and perhaps in the 14 years, they will see integrated products that integrate more functions to maximize the use of such micro-innovations.

Fourth, the integrated design of products not only solves technical problems, but also brings new profit models.

The integrated design of the product integrates the functions of multiple products into one product and achieves the effect of 1+1>2. Moreover, in the implementation of the project, the debugging of multiple products is eliminated, and the cost is also reduced, so the market On the more popular, a seemingly similar product, opened up a new incremental market.

In the traditional product design, under the special circumstances of China, software products have not been reflected in the corresponding prices, and similar intelligent investment algorithms with higher investment have the same fate. Now relying on the product's hardware and software integration design, through the tangible carrier of hardware, binding software and algorithms, to achieve the overall value, from a certain point of view, sales are not hardware, but also the value of integrated solutions.

Fifth, the integrated horizontal development of security systems also requires the unification of technical standards in the industry.

The integrated development of security systems cannot rely solely on the integration of one or two vendors' own products. It also requires the participation of mainstream vendors to open up the gap between various products. Just like the USB interface, plug and play. Therefore, it is still necessary to establish a technical alliance between powerful departments or mainstream manufacturers to promote the unification of industry-wide technical standards, especially the standardization of hardware interfaces and software protocols. This is a long road, but at least there is now With a certain trend, we will wait and see.
