HD-SDI CCTV Cameras
In addition to Geovision HD-SDI cameras, CCTV Camera Pros also carries our own HD security camera product line. These cameras can be used with Geovision HD-SDI cards or with Viewtron stand alone HD-SDI DVRs.
HD-SDI stands for high-definition serial digital interface. It is a standard used in the transmission of uncompressed HD video signals over coaxial cable. The standard is also known as SMPTE 292M and has mostly been used in HDTV production and broadcasting in 720P and 1080P high def resolutions.
Why is HD-SDI now used in some video surveillance systems?
Around 2009 to 2010, some surveillance equipment manufacturers began experimenting with and producing surveillance cameras and DVRs based on the HS-SDI standard. The motivation for this was the ability to achieve 720p and 1080p HD video resolution to compete with higher end IP surveillance systems without the complexity of managing an IP network for installation. The cameras are hard wired use the same type of plug and play type of setup that most security installers are comfortable with (coax cable and BNC connectors).
What type of cable is used to wire HD-SDI CCTV cameras?
Installers can use the same RG59 or RG6 coaxial cable and BNC connectors used with traditional analog CCTV cameras.
Do I need a special type of DVR to record HD-SDI video?
Yes. You can not use a standard CCTV DVR. The DVR must be specifically made to work with the HD-SDI format.
How can I compare HD-SDI video resolution to traditional CCTV camera resolution?
In addition to HD-SDI, CCTV Camera Pros also carries HD security camera systems that use AHD CCTV cameras. One advantage of AHD over HD-SDI is that video cable can be run much longer. RG59 cable can be used to run video from AHD cameras at distances up to 800 feet. Installers can also use AHD video baluns to use UTP cable such as CAT5 instead of coax cable.
