The Talos Security DRH4084 12-Channel DVR is capable of recording the coaxial cable transmitted output of HD-SDI 1080p resolution cameras and SD-D1 resolution cameras. This "Hybrid" functionality enables an existing installation's cameras to be upgraded to HD and utilize the current infrastructure. It is also a great option for anyone looking to get better image quality without having to go to an IP/Network camera solution.
Hybrid Technology combines standard definition (analog signals) and high definition (SDI signals) within the same DVR platform. This makes it possible to upgrade existing systems to high definition cameras in key areas while keeping other zones in the standard definition format -- a simple, more affordable transition to the depth and clarity of 1080P High Definition video.
HD-CCTV is a video system for transmitting uncompressed, high definition, digital video signals, over coaxial cable lines. These standards have been defined by the HDcctv Alliance using the SMPTE HD-SDI protocol. which digitally transmits 720p or 1080p video. HD-SDI stands for High Definition Serial Digital Interface in compliance to standards developed by the Society of Motion Picture and Television Engineers (SMPTE). This allows bit rates of 1.485 Gbits (SMPTE 292M), which is used for HDTV production and broadcasting in 720p and 1080p resolution.
HD-SDI video's transmission medium is based on RG-59 coaxial cable up to 100 meters. HD-SDI systems are preferred option for users who want to upgrade their existing systems to high definition without having to install new cabling.
