HD SDI 1080P HYBRID NVR + DVR
HD-SDI CCTV cameras, also known as HD security cameras.
With the advent of HD-SDI technology for security cameras, users can now capture 1080p resolution video using the same RG59 or RG6 coaxial cable that is used by traditional CCTV cameras.
This new SDI platform work on existing CCTV users whom have invested into coaxial cabling installations, and now are in the market to upgrade their system to HD or Full HD.
The HD-SDI paradigm also makes installation easier for many low voltage installers becauseHD-SDI security cameras follow the same plug and play processes as the traditional CCTV cameras, unlike IP cameras, which do require some level of networking knowledge to setup.
HD SDI 1080P Hybrid Camera vs. CCTV Camera Resolution
Traditional CCTV cameras are capable of resolutions up to about 704 x 480, which is referred to as D1 resolution, which is a hard limit that analog CCTV DVRs must abide by.
Some traditional CCTV cameras can actually capture slightly larger images than D1, but are unable to take advantage because traditional CCTV DVRs are limited to 704 x 480 resolution, which is why D1 is the accepted max resolution in the CCTV industry.
HD-SDI CCTV cameras are capable of true HD 1080p resolution (1920 x 1080). This higher resolution is the same as a high definition television and movies that consumers are use to. The SDI technology behind HD-SDI CCTV cameras is the same as the video cameras that capture video footage for “high def” motion pictures.
