PAUL ON CALL: Going the distance with HDSDI?

When you need to run a very long cable run for a camera or video source SDI is the way to go. 

You can run SDI 300- 400 feet without a repeater. This would allow a near zero delay with your video production. SDI is great to run from your camera to the switcher, switcher to projector, or to a tv. 

Serial digital interface (SDI) is a family of digital video interfaces first standardized by SMPTE (The Society of Motion Picture and Television Engineers) in 1989. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s 

Pros: 

• Long cable runs
  • Low cost
  • Solid picture
  • Easily repaired
  • Goes longer than HDMI 

Cons:
• Need special tools to install

Here are a few that I recommend:
• RG6 Quad Shield Coax
• Klein BNC Ends
