High Definition CCTV Video camerasPosted by Sherwood Cochrane on March 14th, 2021 
High-definition CCTV cameras
As a CCTV installer, you constantly want to buy the very best value cameras out there. The current trends in video products have influenced our customers' perception about security cameras. Large TV makers like Samsung, LG, Sony ready the launch of 11K TV resolution, so it is not a surprise that the CCTV industry is also under great pressure from consumers, that are demanding higher definition.
Hikivsion Home CCTV have faded away from the market. In fact, I had a great deal of difficulties in finding an analogue CCTV camera for just one of my customers. We have been left with two choices, IP and high definition.
IP cameras like AXIS include fantastic resolution. But, the skills required to install them and the price sometimes doesn't suit our customers' budget. In case you are upgrading an existing analogue system, you may have to rewire the whole spot with CAT5 or CAT6. Which can be an expensive option. So, what are the other options?
Analog high-definition CCTV cameras
In recent days, the requirement for analog high definition has gone over the top. Many companies have started manufacturing analog hi-def CCTV cameras.
This article compares a number of the analog high definition technologies available to us.
HD-SDI (High definition - serial digital interface)
The very first to start high definition in analog is HD-SDI. HD-SDI is with the capacity of producing full HD or 1080p resolution. However, the high selling price and compatibility of them have pushed them to the last place.
HD-SDI was used in the early days of camcorders. The only real reason these were not introduced in CCTV video cameras is due to the truth that they were very expensive.
HD-CVI (Hi-def composite video interface)
HD-CVI or hi-def composite video interface may be the latest supplement to the HD CCTV method. This technology is produced by Dahua. HD-CVI technology is capable of transmitting video signal via coaxial cable to no more than 500 meters. It is a big advantage weighed against previous generation analog video cameras. HD-CVI also makes it simple to transmit audio, movie, and data with a unitary coax cable connection. HD-CVI has zero latency and this is another clear advantage weighed against IP technology.
