About Us

Our Story ...

Gem Electronics was founded in 1999 by principals that have been in the design and manufacturing of coaxial products since 1975.

Initially, a manufacturer of standard coaxial connectors and adapters for the CATV, CCTV and general electronics marketplace, we moved quickly to a problem solving institution as we heard and witnessed the Connectorization problems that were persistent in the CCTV market. Installers were experiencing signal failures consistently at an unacceptable rate.

Our mission statement thus became one of solving these problems. We assisted the installer base in drastically reducing that unacceptable failure rate by listening to their concerns and responded first by developing superior connectors including our Universal and UniCrimp BNC Connectors and Compression F, BNC and RCA Connectors. Next we published a cable-connector-selector chart to be sure the proper connector was being used with the coax cable of choice. Finally we developed training videos describing "Connector Fundamentals and another detailing the "Precise Cable Assembly Procedures" to follow to guarantee a perfect termination every time. All within this website.

Our success in the coaxial product field and the emergence of CCTV over UTP technology prompted Gem Electronics to enter into the supply of Baluns and Hubs that would provide the installer a system install that would win more contracts and increase profits substantially. A very informative video was produced titled " Balun Technology", which can be viewed within this website , illustrates various system application options and the cost comparison between the UTP and coax system. We also provide a "distance calculator" to determine the length of UTP that can be run when simultaneously running video/power and data. A most tool when designing the most cost effective and versatile system.

As systems become more sophisticated new challenges arise and Gem Electronics is the company that the industry now turns to for solutions. To answer those challenges we have developed additional problem solving products including:

  • Coax to IP Converters and Extenders
  • Diplexers
  • A CCTV Wireless Transmit/Receiver Kit that produces a ROCK SOLID PICTURE
  • HDcctv product line that is certified to HDcctv universal standards.

Today Gem Electronics offer Twist-On BNC connectors to HDcctv Cameras, all at superior quality and profit increasing costs.
