What is the difference between HDCVI and HDSDI?

Hello, I am happy to answer your question:

Comparative analysis of HDCVI camera and high-definition IPC

What is IPC and what is HDCVI? What is the relationship between the two and what is the difference? Who has the biggest profits, and who will be the mainstream in the market in the future?

1. Concept

IPC: IP CAMERA is a new generation camera that combines traditional cameras and network technology. It is a digital device based on network transmission. Equipped with a network output interface, the network camera can be directly connected to the local LAN.

HDCVI: High Definition Composite Video Interface (HDCVI) is a coaxial cable-based analog modulation technology that transmits progressive scan high-definition video. It is an upgraded product under the analog surveillance technology architecture. , it is still a closed-circuit analog monitoring system.

2. 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 it is for engineering quotations. The general direction of high-definition in the future is high resolution. rate, high frame rate. IPC can reach 100W, 130W, 200W, or even 300W, 500W, 800W@30 frame image output.

HDCVI: It is only responsible for signal collection but not signal compression. Due to the limitation of the transmission mode, it can only achieve a maximum of 200W@30 frames.

3. Application

IPC: an excellent example of industry-level + civilian application. Since its development in 2010, IPC has a complete range of products, high cost performance and wide application, and has been unanimously accepted and recognized by consumers. At the end of 2013, in addition to industry applications, home security was also being promoted in full swing. With the promotion of 4G networks, cloud storage, etc., the prospects for home security are promising. As far as the current mainland video surveillance market is concerned, high-definition products account for more than 30% of the market share, of which network high-definition (IPC, NVR) accounts for about 95% of the market share, and digital high-definition (HD-SDI, HDCVI) accounts for about 5% .

HDCVI: A niche transitional product with narrow application scenarios. It is mainly used in financial institutions with small geographical areas but high real-time requirements. Home security is entering the Internet era. Compared with the network openness and standardization of IPC, HDCVI is not suitable for home scenarios because it cannot be directly connected using a computer/mobile phone and must use its supporting back-end equipment.

4. Profit

IPC: Project Profit = Project Quotation – Comprehensive Cost. The high-definition image quality of IPC is much higher than that of HDCVI, which is conducive to higher prices. At the same time, the low consumption of wires, simple lines, short construction period, and convenient later maintenance can ensure maximum profits.

HDCVI: The front-end is uncompressed, resulting in a large amount of back-end data. Although some of the original analog monitoring transmission cables can be used for image transmission, the front-end, optical transceiver, and back-end all need to be replaced. At the same time, the effective transmission distance of HDCVI is about 400 meters. The transmission signal above 400 meters is seriously attenuated. Currently, there is no equipment that provides signal amplification, so it is impossible to achieve a solution for transmission over 400 meters. The scalability is average and the intelligent analysis function cannot be integrated. It can be seen that the comprehensive cost of HDCVI is much more expensive than that of IPC, which directly results in the profit being far less than that of IPC engineering projects.

5. Market

IPC: Hikvision, Zhongwei Century and many Shenzhen manufacturers have focused their research and development on IPC. The promotion of more manufacturers will be more beneficial As IPC technology matures and becomes more common in the market, and as it continues to develop, IPC's cost advantage will become more and more prominent and its market share will increase. Beyond analog monitoring, it is just around the corner.

HDCVI: Currently there are only a few manufacturers promoting HDCVI, and most of the manufacturers promoting HD-SDI (the effective transmission distance of HD-SDI is about 100 meters) have also shifted their focus to IPC. This will lead to consumers having a single choice and increasing risks. If merchants rashly focus on HDCVI, once this technology is completely replaced by IPC, merchants will inevitably 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 respond to the market. Faced with the current great opportunity for comprehensive promotion of network high-definition and strong market demand, merchants should be proactive, actively increase distribution volume, seize market share in a timely manner, maximize profits, and at the same time accumulate network high-definition technology experience and successful project cases. After all, doing business Well, making money is the last word.
