Network cable DVR breaks through the price war

—— Take the path of differentiation and open up the market to face the price war Panhai Sanjiang has launched a new patented product – network cable DVR

Adversity survival to avoid price war to open up the New World There are data, Haikang, Dahua several major DVR (digital hard disk video recorders, English abbreviation DVR) giant has occupied more than 70% of this area's share. However, the sudden price war at the beginning of May once again broke the tranquility of the DVR market. Leading companies such as Haikang and Dahua intend to gain market share in low-end products and expand their market territory once again. The spring and autumn Warring States battle for dominance was tagged by the historian as the label of “unrighteous warfare.” Regardless of the final outcome, this DVR price war will also be categorized by the industry as “a war without winners”.

In the face of a price war triggered by the low-end market, mid- to high-end product companies will respond passively to price cuts. Faced with the price war caused by leading enterprises, how should the second and third line enterprises face?

It is understood that the second-tier companies currently involved in this market price war are not willing to be in a passive position and are being dragged down by the price war. Instead, they are changing their strategies, moving away from “war”, taking the path of differentiated development, and opening up their own markets. Panhai Sanjiang Electronics Co., Ltd. is one of them.

Shenzhen Panhai Sanjiang Electronics Co., Ltd. (abbreviated as Pan Hai Sanjiang) is a high-tech company under the China Ocean Group. Founded in 1985, it is a fire-fighting electronics, building intercom, and intelligent monitoring product R&D, production, sales, and engineering construction. , maintenance, and installation of state-level high-tech enterprises. Pan Hai Sanjiang adheres to the people-oriented management philosophy, regards talent as the company's core resources, and uses technology as the basis for survival. At present, it has established three R&D centers in Shenzhen, Guangzhou, and Wuhan, and has more than 100 professional R&D personnel.

Faced with the impact of price wars, Panhai Sanjiang gave full play to its technological advantages, and launched a network-line embedded hard disk recorder to open up new markets with the design concept of “project-oriented”. This brings cost-effective products to end-users. Customers bring new profit growth points.

The entry point for development in adversity—the word “innovation” has long been known by people. In recent years, almost all walks of life have been exploring “innovation”. Some people call it the soul of the company's growth, and others regard it as the source of the development of the industry. However, we should clearly realize that innovation is not an accidental idea. In a homogenized industry competition environment, security innovations must have sufficient lethality.

A security industry person once said: “How fast the market changes, how fast the product innovation will be!” and for the sudden price war, Panhai Sanjiang has accumulated rich experience in the field of embedded systems and engineering. With the "engineering-oriented" design concept, innovative digital differential technology was applied to the field of video surveillance, and a cable-line embedded hard disk recorder (network cable DVR) was successfully introduced.

The most important feature of this type of equipment is the use of ultra-five-line video transmission media, which can greatly save customer investment. It is well-known that the transmission of video over a Category 5e or twisted pair cable has been on the market for some time. However, during long-distance transmission, image color loss is large and the screen is dark and not clear enough. In addition, DVRs and twisted pair transmitters are used. Produced by different manufacturers, the overall reliability of the system is subject to too many uncertainties and has been questioned. Through the joint research with the engineering department, Panhai Sanjiang has given full play to its technical advantages. The core processor of the DVR samples and compares the received video signals, and then performs automatic gain control so that the video signal is always in range with the standard signal. Staying close, it is a good solution to the color loss and screen graying when transmitting video over twisted pair. This technological innovation is called digital differential technology. For the transmission part, the lightning protection performance of the product is improved, and the equipment is ensured to operate as far as possible from the threat of disasters.

In addition, the ultra-fifth-class space is much smaller than the coaxial cable, which is especially suitable for the needs of intensive monitoring and facilitates construction. Using RJ45 as the connection interface, the construction is simple, the connection is stable and reliable, avoiding the complex construction and connection instability when the BNC interface is adopted, which can help the engineering customer to save the labor cost and construction cost, and can help the terminal customer to save the maintenance cost.

At present, this type of equipment has obtained national patent authorization. The authorization number is: ZL2010 2 0631574.6.

The most cost-effective video surveillance system - provincial and provincial lines In most video surveillance systems, wire costs account for most of the overall investment, if we can guarantee the quality of video transmission, save on wire cost and construction cost, it will be high The key to a cost-effective system. In actual use, a Category 5 cable contains 4 pairs of twisted pairs. The amount of wire used is equivalent to about a quarter of the use of coaxial cable, and the unit price is also more advantageous. Video, in line with demand. To give an example: each monitoring point from the average distance of 850 meters from the monitoring room calculation, the traditional DVR using coaxial cable transmission, wire length: 16 * 850 = 13600 meters; using Pan Hai Sanjiang cable type DVR, 16 monitoring video Only four cable transmissions are required. The total length of the wire is: 4*800+50*16=4000 meters; the length of the wire will save two-thirds.

Convenient to replace the coaxial cable with a super-five cable, you can simplify the process. Take a 300-point monitoring project as an example. With coaxial cables, 300 cables need to be laid at the monitoring center. However, if you use a Category 5e cable, Only 75 strips need to be laid, which greatly reduces the number of wire rods, saves space for wire rods, and facilitates construction. To a certain extent, it greatly facilitates post-maintenance. In addition, the use of high-quality network cable interface and RJ45 connection, effectively increase the reliability of the connection, to avoid the use of coaxial cable when using BNC interface connection problems, a lot of peace of mind.

The front-end part of the provincial laborers adopts a new type of networking method. By adding intermediate branch devices, it can realize centralized on-site power supply of the camera. The power passes through the branch device to each port, each port can transmit video and power, overcoming the trouble of the camera to take power (see Figure 1) is extremely conducive to on-site construction. The use of standard network cable connection methods to reduce the requirements of manual quality can save training time, improve construction proficiency, and match network cable testers to easily identify outliers. The construction person in charge of Shenzhen Zhenhua Road Branch of Little Sheep National Chain Co., Ltd. said: “Before the two professional technicians spent four days of work, now two ordinary migrant workers are required to spend more than one day to complete the work, and the site is more tidy. Orderly."

In summary, through the savings in wire, construction costs, and maintenance costs, a very cost-effective video surveillance system will be built.

This network cable DVR is professionally speaking, it does have many advanced technical features, but in actual use, in the face of his different customers, its shining advantages are not as able to stand the test?
