HD-SDI at a Glance

High Definition – Serial Digital Interface

HD-SDI is capable of providing 1080P High Definition images.

HD-SDI CCTV is a relatively new technology, only becoming readily available since late 2012. It is very similar to analogue CCTV in the way it is installed - i.e using RG59 coax cable to transmit a signal from the camera to a recorder. The major difference of course is it can transmit 1080P High Definition Images.

However, as it is a digital signal, the video tranmission distance is limited to approx 90 metres using good quality coax cable - then you will need to add in a HD-SDI repeater every 90 metres.

HD-SDI products are not compatible with any other format.

1080P Resolution - is 1920 x 1080 pixels - that's a total of 2,073,600 pixels.

That's up to 5 times the image quality of SD CCTV!
