How Do I Choose the Best CCTV Security System?

HDcctv (High Definition Closed Circuit Television) system is a video surveillance system. High-definition (HDTV) video signals compatible with the broadcast industry can be digitally transmitted via traditional CCTV media without packaging, and there is no human eye. Perceived compression delay.

(To date, the HDcctv Alliance's efforts have only attracted four small companies HD-DSI chip maker Gennum, video codec startup firm Stretch, camera maker Ovii, and Rockoff s former employer Taiwan s security system ODM maker. EverFocus.)

HDCCTV is a new standard for high definition surveillance system (High Definition Surveillance Systems) applications proposed by several chip and system vendors in 2009. Although the standard was proposed only two years ago, due to the advantages of its own standard and the addition of more and more manufacturers, the HDCCTV standard is now

1. The results of the old analog system can be used in the wiring scheme without rewiring. The device management can also use the architecture of the old analog system. To upgrade from the old system, you only need to replace the hardware equipment (camera, DVR, etc.). There are other inputs. There is no need to go through the new knowledge training required for system changes.

2. Undistorted reliability: Unlike digital monitoring data, it is transmitted in a packetized network after compression. It is transmitted on a coaxial cable as uncompressed digital data without distortion.

3. High-definition real-time image: It does not produce compression and packetization during the transmission process, and does not cause image delay problems like ordinary digital high-definition. It is particularly suitable for real-time monitoring.

4. Provide high-definition images required for intelligent surveillance (IVS): Uncompressed high-definition images provided by HDcctv, the integrity of the image is guaranteed, and it can provide the best source of high-definition images required for intelligent surveillance.

In fact, the most fundamental benefit brought by HD-CCTV is that it can be smoothly upgraded from the current large number of analog video surveillance solutions to high-definition solutions. This is a way that end users, system integrators, and now a large number of analog camera manufacturers are willing to accept.

Objectively speaking, IP-based standards and HD-CCTV each have their own strengths, but in the current security industry landscape, the future of HD-CCTV is exciting and looking forward to.

Of course, HD-CCTV has not experienced a long time since it was proposed. Regardless of introduction from camp members, marketing, and technical difficulties, it is still in its infancy. For example, HD-SDI transmission distance and traditional SDI In comparison, there is still a big gap. HD-CCTV cameras and DVRs have a small selection area and high cost. Market promotion is also far behind the IP high-definition monitoring solution. However, as the technical difficulties are overcome one by one, more and more companies (such as Infineon) and manufacturers join, the cost of hardware and solutions will be lower and lower, and they will receive more and more attention from the security industry.

According to the development needs of the security market, many security companies are actively engaged in the development of HD-CCTV board solutions, and INFINOVA, relying on its success in analog surveillance and digital video surveillance solutions, has good development prospects in HDCCTV. Next, the first HD-CCTV solution was launched. Especially recently, Infineon has officially joined the HDcctv Alliance. Todd Rockoff, Executive Chairman of the HDcctv Alliance, said that Infineon has complete core products, including video control equipment, megapixel / network / analog cameras, dedicated cameras, optical transceivers and custom systems.

After joining the alliance, Infineon will provide more options for integrators and customers by complementing a series of HDcctv-compliant products. Infineon will work with many HD-CCTV camp manufacturers to promote the development of HD-CCTV and contribute to the development of HD video surveillance.
