Analog high definition CCTV cameras.
In recent days, the demand for analog high definition has gone over the top. Many producers have began making analog high definition CCTV cameras. This article compares some of the analog high definition technologies open to us.
Getting Down To Basics with Options
HDSDI (High definition – serial digital interface).
5 Uses For Installations
The very first to begin high definition in analogue is HDSDI. HD-SDI is really capable of creating complete HD or 1080p resolution. On the other hand, the high price and compatibility of these have shoved them to the last area. HD SDI was utilized in the early days of camcorders. The sole reason they are not introduced in CCTV cameras is as a result of truth that they were quite pricey.
HD-CVI (High definition composite video interface).
HD-CVI or high definition composite video interface is the newest addition to the HD CCTV system. This technology is manufactured by Dahua. HD CVI technology is effective at carrying video signal via coaxial cable to some maximum of 500 meters. It is a enormous advantage in contrast to preceding generation analogue cameras. HD CVI also allows you to transmit sound, video, and data with one single coax cable. HD-CVI has zero latency and this is just another clear advantage compared with IP technology.

AHD (Analogue high definition).
AHD technology is developed by Next-chip Korea. AHD supports 720p and 1080p video resolutions. AHD technology also has pros and cons, AHD chip-sets are generally the cheapest among High Definition chip-sets, hence the final product cost is somewhat cheaper than HD TVI or HD CVI. AHD cameras can carry video signals through RG59 and RG6, hence it might carry signal up to 500m without losing strength. In addition, it supports audio over coaxial.
The verdict is, everything depends on your job requirement. If your customer is more worried about video resolution, and if they’re seeking to use a video management system, IP cameras may be appealing to them.
