Are all SDI cables the same?
There are 4 common SDI standards. The original SDI supports 480i video, HD-SDI increased the supported resolution to 1080i/720p. 3G-SDI supports 1080p, and 6G-SDI supports up to 4K at 30Hz. The12G-SDI is still in draft status, but it will support 4K signals at 60Hz.
What is HD-SDI cable?
HD-SDI is a high-definition digital component serial interface. The HD-SDI camera, based on the serial link standard of the SMPTE (film and television Engineer Association), is a high-definition and real-time video camera that transmits uncompressed digital video through 75 ohm coaxial cables.
What cable do I need for 6G-SDI?
6G-SDI uses just one BNC cable to send 10 Bit 4:2:2 4K at 30p or 24p. You will need one BNC cable that supports 6 Gb/s of bandwidth for 6G-SDI.
Is SDI cable the same as RG6?
Similarly, an “SDI cable” is typically an RG59/RG6 or something cable (which is a variety of coax) terminated in BNC connectors that carries the SDI protocol. So, yes! The standard is RG-6 cable but it’s also acceptable to use RG-59 (75-Ohm version) for runs under 100′.
How long can you run an SDI cable?
Cabling and Loss HD-SDI is regularly transmitted over low-loss digital video grade RG6-style coaxial cable up to a nominal maximum distance of about 100 meters.
How long can you run HD-SDI cable?
about 100 meters
HD-SDI is regularly transmitted over low-loss digital video grade RG6-style coaxial cable up to a nominal maximum distance of about 100 meters.
How far can you run SDI?
How far can you run 12G SDI?
Starting Down the Path Toward 12G-SDI Although it has changed over the years, the magic distance for video cables today is 100m (328 feet).
How does HD-SDI work?
The data transmission format of HD-SDI is basically the same as the transmission format of SD-SDI, and the luminance signal Y and the color difference signals Cb and Cr subjected to time-division multiplexing are handled as 20-bit words. Each 20-bit word corresponds to a color difference sample and a luminance sample.
How big is a HD SDI video recorder?
High Definition HD SDI and EX-SDI Digital Video Recorders and Cameras 720p & 1080p (1000TVL Resolution) up to 2 Megapixel. Fully Digital Systems based on Coaxial Wiring. High Definition Picture up to 1080p (1000TVL) using standard coaxial cable and compatible SDI HD CCTV Cameras.
What kind of cable is used for HD SDI?
Broadcast grade HD-SDI cable custom made using the highest quality Sommer cable and Neutrik connectors.
Can a HD-SDI DVR accept analog BNC inputs?
The very thin coaxial or Siamese cable (usually pre-made lengths) will not transmit an HD signal. And if the cable’s distance is beyond 100-150 feet, an HD-SDI extender may have to be used. An HD-SDI DVR cannot accept analog BNC inputs, unless it specifically lists that capability.
How does a SDI DVR work in a CCTV system?
SDI is a fully digital CCTV System, where signal from each and every Surveillance SDI Camera is sent back to the SDI DVR Unit via Standard Coaxial Cable. Signal is fully digital, not analog like with Regular CCTV Systems. Since every SDI Camera is connected directly to the SDI DVR,…
