Why use EX-SDI technology?

Why use EX-SDI technology?
Even though HD analog products seem to prevail in the environment of using coaxial cables around the world, other HD-over-coaxial technologies such as HD-SDI, EX-SDI, and ccHDtv, still remain an important part in certain niche projects. Korean manufacturers are now the biggest supporters for HD-SDI and EX-SDI technology. asmag.com interviewed Sun Myung Electro-Telecom, a Korean manufacturer and developer of security and video surveillance equipment to talk about EX-SDI technology at secutech this year.
Even though HD analog products seem to prevail in the environment of using coaxial cables around the world, other HD-over-coaxial technologies such as HD-SDI, EX-SDI, and ccHDtv, still remain an important part in certain niche projects. Korean manufacturers are now the biggest supporters for HD-SDI and EX-SDI technology. asmag.com interviewed Sun Myung Electro-Telecom, a Korean manufacturer and developer of security and video surveillance equipment to talk about EX-SDI technology at secutech this year.

With over 10 years of experience in the industry, the company is looking toward expanding their market base with their new line of EX-SDI cameras. "HD-SDI products are usually high-end, but we are now producing a lower-end version to become more competitive in the market. Our company motto has always been to provide high quality items at competitive prices," said Wayne Lee, Sales and Marketing for Sun Myung Electro-Telecom.

According to Lee, one of the major advantages of this technology lies in its video transmission capabilities. "The EX-SDI is the extended version of HD-SDI. So while the distance for HD-SDI is 200 meters, it is now extended to 400 to 600 meters using this technology. That is what we have developed."

Unlike analog cameras, these cameras are fully digital so as to eliminate any video loss or image quality degradation that may result from longer distance transmissions.

Another advantage of these systems is that they are calibration-free. Compatibility would not become an issue and installers wouldn't need to spend time making adjustments to resolution, edge enhancement, color sense, etc. "If they buy our DVRs and they have other manufacturers' HD-SDI cameras, they don't have to do precise tuning," commented Lee.

On the other hand, installation of HD analog systems would be more troublesome since there would be a need to tinker with each of the cameras and DVRs used in the same system to ensure clear images and recordings.

Other benefits of EX-SDI includes good durability against electronic noise disturbance and the system is capable of high resolution images of a maximum of 4K UHD at 30 fps. It is also flexible enough to allow further expansion in the future if the user desires it.
