HD-SDI CCTV cameras, also known as HD security cameras, are capable of capturing video surveillance footage at 1080p resolution (1920 x 1080 pixels). These high definition surveillance cameras must be used with an HD-SDI surveillance DVR. If you are unfamiliar with the difference between HD-SDI and traditional CCTV camera resolution, we highly recommend that you take a look at the comparison HD and SD images in this article. If you would like to use a combination of HD and SD cameras, CCTV Camera Pros offers hybrid DVRs that can accommodate both types of cameras on a single system.

HD CCTV cameras use high definition serial interface (HD-SDI) technology which enables full 1080p resolution video surveillance using standard RG59 coaxial cable. There are some special considerations to be aware of when planning an HD-SDI surveillance system. These include cable type, cable distance, and compatibility with DVRs.
Because HD video uses more bandwidth throughput than traditional standard-definition CCTV cameras, installers must use RG59 or better coax cable. Pre-made CCTV cables that are a thinner gauge than RG59 will not be able to transmit the video signal effectively. It is also recommended to use a high quality 95% or better copper cable. The effective distance that a video signal can transmit over RG59 cable is 300-400 feet without the use of an HD-SDI transmission extender, which can extend the signal an additional 300 feet.
RG59 Siamese Cable Options
The following RG59 cable options have been tested with HD-SDI cameras and are guaranteed by CCTV camera pros to work effectively with the HD cameras that we sell.
HD-SDI cameras do require a specialized / HD-SDI compatible DVR in order to record high definition video. CCTV Camera Pros offers both stand-alone and PC based HD-SDI recorders that work with all of our HD cameras. Our Viewtron hybrid DVRs work with both traditional CCTV and HD-SDI CCTV cameras. Our Geovision PC based DVRs can be custom built to be a pure HD-SDI recorder, or they can be build as a hybrid recorder to work with traditional CCTV and/or network IP cameras.
