CCTV IN THE UNITED STATES
The first US manufacture of CCTV equipment was established in 1946 by a major manufacture of large power plant boiler systems to fill a need that was not available on the commercial
market. The company had just finished commissioning a large 1 mega-watt power generation system for a Virginia Utility. Several days after startup the boiler lost water and exploded, placing the boiler out of service for over a year. Water level gauges are located approximately 3 stories above the control room. Prior to the development of CCTV gauge viewing, a system of mirrors was used to reflect the gauge image to the control room. One of the mirrors at Virginia Electric Power had been damaged and the control room was not able to monitor the. When the water level dropped below the minimum the boiler exploded and was heavily damaged.
The boiler manufacture searched the available technologies and found that towards the end of the Second World War, CCTV had been used aboard naval ships for remote viewing. A search of patents reveled that Philo T. Fransworth had been issued a patent on an Image Dissector Television Pickup tube. The boiler manufacture purchased the rights and began manufacturing remote CCTV gauge viewing systems using the Farnsworth design. These cameras were very large, heavy, had 200-line resolution, bad "S" distortion and required a lot of light and power.

Sam Genensky first applied closed-circuit television (CCTV) technology for large-print reading in the late 1960s. Although the technology was somewhat crude by today's standards, the basic concept has not changed. Genensky's CCTV used a camera on a stand and a special lens to magnify text onto a television monitor. It was a simple way to create a much stronger magnifier than anything that existed through basic optics. There was no other technology that provided this level of magnification, and CCTVs soon became the accepted way for people with severe low vision to read.
