What is IPC? What is HDCVI? What is the relationship between IPC and HDCVI? What is the difference between IPC and HDCVI? Let's let Xiaobian analyze it for you.
The difference between IPC and HDCVI
IPC: IP Camera (IP CAMERA) is a new generation camera that combines traditional camera and network technology. It is a digital device based on network transmission. It has a network output interface and can directly connect the network camera to the local area network.
HDCVI: High Definition Composite Video Interface (HD) is a kind of high-definition video based on coaxial cable that uses progressive modulation technology to transmit progressive scan. It is an upgrade product under the analog monitoring technology architecture and still belongs to closed-circuit simulation. surveillance system.
The difference between IPC and HDCVI
IPC: Seeing more clearly has always been the goal pursued by consumers. The future direction of high definition is high resolution and high frame rate, while IPC can reach 100W, 130W, 200 W, and even 300 W, 500 W, 800 W@ Output of 30 frames of images.
HDCVI: It is only responsible for the signal acquisition and is not responsible for the compression of the signal. The maximum transmission mode can only achieve 200W@30 frames.
The difference between IPC and HDCVI
IPC: an excellent example of industry-level + civilians. Since its development in 2010, IPC has a complete range, high cost performance and wide application, and has been accepted and recognized by consumers. At the end of 2013, in addition to industry applications, home security is also in full swing, with the promotion of 4G networks, cloud storage, etc., home security prospects can be expected. As far as the current mainland video surveillance market is concerned, HD products have a market share of more than 30. Among them, network HD (IPC, NVR) accounts for about 95% of the market, and digital HD (HD-SDI, HDCVI) accounts for about 5.
HDCVI: A small-scale transition product with narrow application scenarios, mainly used in financial places where the geographical area is not large but the real-time requirements are relatively high. Home security is entering the Internet era. Compared to IPC's network openness and standardization, HDCVI is not suitable for home scenes. Because it cannot be directly connected to a computer/mobile phone, it must use its back-end equipment.
The difference between IPC and HDCVI
IPC: Engineering Profit Engineering Quotation – Comprehensive Cost. IPC's high-definition picture quality is much higher than HDCVI, which is good for high prices. At the same time, the wire consumption is small, the line is simple, the construction period is short, and the later maintenance is convenient, so as to ensure the maximum profit.
HDCVI: The front end is uncompressed, resulting in a large amount of data on the back end. Although the original part of the analog transmission cable can be used for image transmission, the front end, the optical transceiver, and the back end need to be replaced. At the same time, the effective transmission distance of HDCVI is about 400 meters, and the transmission signal of 400 meters or more is seriously attenuated. At present, there is no device for providing signal amplification, so the solution of transmitting more than 400 meters cannot be realized, and the expansion is general, and the intelligent analysis function cannot be integrated. It can be seen that the overall cost of HDCVI is much more expensive than IPC, which directly leads to a far less profit than the IPC project.
The difference between IPC and HDCVI
IPC: At present, many manufacturers have focused their research and development on IPC. The promotion of more manufacturers is more conducive to the maturity of IPC technology and the generalization of the market, and the continued development of IPC cost advantages will become more prominent and market share. It will also get bigger and bigger, and beyond analog monitoring is just around the corner.
HDCVI: At present, there are only a few manufacturers promoting HDCVI, and most manufacturers who promote HD-SDI (HD-SDI effective transmission distance is about 100 meters) have also turned their focus to IPC, which leads to a single choice for consumers. The risk is increased. If the merchant rushes to focus on HDCVI, once the technology is completely replaced by IPC, the merchant will fall into a passive situation and will inevitably fall behind other peers. In fact, many times, choice is more important than hard work.
From the above five points, we can see the difference between IPC and HDCVI, and more information about the new camera technology, please continue to pay attention to the hot security investment network.
