    HDCVI

    4K AHD/CVI/TVI cameras are not yet to come

    4K Security Cameras

    4K IP camera is the hot topic during the recent two years. As the main trend, the global top HD video solution providers such as Ambarella and Hisilicon developed and launched SoC processors which featuring 4K video encoding and decoding capability, at the same time, many leading video surveillance brands launched new high-end IP cameras supporting 4K ultra high definition resolution. Will 4K ultra resolution analog cameras be available in the surveillance market soon? Well, the answer is 4K analog cameras isn't yet to come.

    AHD vs HD-CVI what's difference between them?

    Since the popularity of CMOS image sensor, the traditional analog video surveillance is undergoing tremendous transformation. More and more security camera manufacturers launch new high definition analog solutions, which are, HD-SDI, HD-CVI, HD-TVI, and now HD-AHD. All of them can deliver 720P/1080P high definition images, and transmitting the video over traditional coaxial cable. HD-SDI cameras and HD-SDI DVR are the most expensive HD analog equipment among them, which is the main reason HD-SDI technology doesn't widely used in HD analog surveillance system. Compared with HD-SDI, the cameras based on other three technologies are very competitive.

    Analog HD Solution: 960H AHD HDCVI HDTVI HDSDI

    Video security system becomes so cheap nowadays. Currently, we have many HD solutions to allow user setup a complete HD video surveillance system. The latest solutions including 960H, AHD, HDCVI, HDTVI, as well as HDSDI.

    960H is released and promoted by Sony, who is the leader in past traditional video surveillance technology. These cameras are based on Sony 960H image sensor and Effio DSP can deliver maximum over 700 tv lines resolution. Some camera manufacturers put the 800 tv lines on camera's tag & its specification.

    HD-CVI DVR Technology Dahua DH-HCVR1604HG-SF Tested

    As we know, traditional close circuit television system only can achieve 625TVL in theory, but after the introduction of 960H, and latest HDCVI technology, now user can achieve true analog high definition monitoring. Technology from Dahua, HDCVI HD analog technology can achieve full HD 1080P video surveillance, through video transmission through coaxial cable. Today, we are going to introduce Dahua HDCVI DVR with our readers

    HDCVI vs HD-SDI, HDCVI camera vs IP camera

    HDCVI is based on coaxial cable to transmit composite video signal brand-new technology, adopting analog signal modulation technology, and progressive scan CMOS image sensor to deliver 1280H (1280x720) and 1920H (1920x1080) high definition video signal. HD-CVI technology can output megapixel resolution, including 1280H@25fps, 1280H@30fps, 1280H@50fps, 1280H@60fps, 1920H@25fps, 1920H@30fps six formats. Adopting the HDCVI technology can achieve uncompressed, lossless, without delay video transmission between HDCVI camera and HDCVI DVR. More over, HDCVI can transmit audio and control signal, up to 500 meters long range transmission distance.

    HDTVI vs HDCVI, who is the winner?

    As a popular trend, the security industry began producing cameras HD and Full HD to meet market demands of high definition video surveillance. Surveillance systems have today as the core technology HDCVI which presently is the market leader for analog surveillance systems. It entered the market recently took over the market due to lack of competition, HDCVI technology supports 720p HD  and full HD 1080P video recording. HDCVI systems technology is improved and applied to many DVR recorders and weatherproof bullet, vandal-resistant dome and speed dome camera surveillance cameras. Since HDCVI systems do not have to change the analog cables. HDCVI systems' installation costs are much lower. 

    What are the advantages of HD-CVI Camera?

    Today's monitoring system has started its transformation from conventional "being able to see" system to "high definition" system. Henceforth, here born with many megapixel HD technologies such as IP, HD-SDI, HD-CVI, SLOC and so on, also introduced new HD technologies including HDTVI and AHD.

    Before the HD-CVI technology, IP technology has been dominated as the only megapixel resolution solution for many years, compare with IP technology, other technologies occupy tiny market shares. HDCVI  technology is now reversing this situation, why HDCVI products can do this, this article will explain it, and let you know what the advantage of HD-CVI technology.

    What's HDCVI camera, and its advantage?

    What's the HDCVI camera? To answer this question, you need to know what the HDCVI, the HDCVI is the abbreviation of High Definition Composite Video Interface (HDCVI), which is one of recent technologies for offering high definition solution to analog surveillance system (CCTV).
