First Witness Video Surveillance Systems

Backgrounds Unlimited, Inc., trading as First Witness Video Surveillance Systems, abbre­vi­ated First Witness, was a manufacturer and reseller of covert audio and video surveillance sys­tems, based in Mount Sidney (Virginia, USA). The company was founded on 1 May 1991 1 by Thomas Scott Cline – a former Waynesboro police narcotics officer – after he saw a need for sur­veil­lance cameras for drug busts. Today, the company is known as First Witness Security.


Cline developed his first wireless video surveillance system whilst he was still working as a police officer, as part of a state police drug task force. In 1991, he started the business together with his wife Teresa from their home in Staunton, under the name Backgrounds Unlimited, Inc. In early 1995 he left the police force to persue a full-time business career. About 18 months later, in April 1996, the business was transferred to a larger premises in Mount Sidney in April 1996.

Most, if not all, of First Witness' products were imported from countries like Taiwan and China. Between 1999 and 2004, only four products were submitted to the FCC for approval, and even those were developed and manufactured by the Taiwanese company RF-Link Systems, Inc. These products were subsequently concealed in inconspicuous household items, such as a clock/radio.

Around 2017, when the covert video market became saturated with cheap devices from Chinese websites like AliExpress, First Witness' turnover began to decline. The company subsequently converted itself to a supplier and installer of home and business surveillance and alarm systems, and renamed itself First Witness Security. It is currently located in Harrisonburg (VA, USA).

  1. In the 2009 company brochure [I] it is claimed that First Witness was established in 1990, but on his Linkedin page the founder/owner confirms that it was 1 May 1991. We believe the latter to be correct as it aligns with the company's registration details.
