What is an HDCVI camera?

Hello, I'm glad to answer your question:

Comparative analysis of HDCVI camera and high-definition industrial computer

What is IPC and what is HDCVI? What's the relationship between the two? What's the difference? Who has the biggest profit and who will be the mainstream of the future market?

I. Concept

IPC: IP camera is a new generation camera which combines traditional camera and network technology. It is a digital device based on network transmission, which has a network output interface and can directly connect the network camera to the local LAN.

HDCVI: High-definition composite video interface is a kind of high-definition video based on coaxial cable, which adopts analog modulation technology to transmit progressive scanning. It is an upgraded product under the framework of analog monitoring technology and still belongs to closed-circuit analog monitoring system.

Second, image quality.

IPC: Seeing more clearly has always been the goal pursued by consumers. At the same time, the higher the image quality, the better the project quotation. The general direction of high definition in the future is high resolution and high frame rate. IPC can output 100W, 130W, 200 W, even 300 W, 500 W, 800 W@30 frames of images.

HDCVI: only responsible for signal acquisition, not signal compression. Limited by transmission mode, it can only achieve 200W@30 frames at most.

Third, application

IPC: an excellent example of industry level and popularization. Since the development of 20 10, IPC has a complete range, high cost performance and wide application, which has been unanimously accepted and recognized by consumers. At the end of 20 13, besides industrial applications, home security is also in full swing. With the popularization of 4G network and cloud storage, the prospect of home security can be expected. As far as the whole mainland video surveillance market is concerned, the market share of high-definition products is over 30%, among which network high-definition (IPC, NVR) accounts for about 95% and digital high-definition (HD-SDI, HDCVI) accounts for about 5%.

HDCVI: a niche transition product with narrow application scenarios, mainly used in financial places with small area but high real-time requirements. Home security is entering the Internet age. Compared with the network openness and standardization of IPC, HDCVI is not suitable for home scenes, because it cannot use computer/mobile phone direct connection, and must use its supporting back-end equipment.

Fourth, profit.

IPC: project profit = project quotation-comprehensive cost. The high-definition image quality of IPC is much higher than that of HDCVI, which is beneficial to high price. At the same time, the line consumption is less, the line is simple, the construction period is short, and the later maintenance is convenient, which can ensure the maximum profit.

HDCVI: the front end is not compressed, resulting in a large amount of data in the back end. Although some original analog monitoring transmission cables can be used for image transmission, the front end, optical transceiver and back end need to be replaced. At the same time, the effective transmission distance of HDCVI is about 400 meters, and the signal transmitted above 400 meters is seriously attenuated. At present, there is no equipment to provide signal amplification, so it is impossible to realize the solution of transmission over 400 meters, and the expansibility is general, so it is impossible to integrate intelligent analysis function. It can be seen that the comprehensive cost of HDCVI is much more expensive than that of IPC, which directly leads to the profit being far less than that of IPC project.

Verb (abbreviation for verb) market

IPC: Hikvision, Zhongwei Century, many Shenzhen manufacturers take IPC as the core. The promotion of more manufacturers is more conducive to the maturity of IPC technology and the popularization of the market. The cost advantage of IPC will become more and more prominent, and the market share will become larger and larger. It is just around the corner to surpass analog monitoring.

HDCVI: At present, there are few manufacturers promoting HDCVI, and most manufacturers promoting HD-SDI (the effective transmission distance of HD-SDI is about 100 meters) have also shifted their focus to IPC, which leads to a single choice for consumers and increased risks. If businesses rashly focus on HDCVI, once the technology is completely replaced by IPC, they will fall into a passive situation and fall behind other peers. In fact, many times, choice is more important than hard work.

Follow the trend and push according to the market. Faced with the great opportunity and strong market demand for the comprehensive promotion of network HD, businesses should be preconceived, actively increase circulation, seize market share in time, maximize benefits, and accumulate technical experience and successful engineering cases of network HD. After all, making money is the last word in business.
