It was the foundation for video monitoring, remote-controlled door locks, push-button alarm triggers, instant messaging to security providers and police, as well as two-way voice communication. Brown's invention has led to the creation of many new home security systems that rely on video systems, remote door locks, and quick emergency response actions. These systems have become the leading security for homes and small businesses all over the world. The fame of Brown's device also led to the more prevalent CCTV surveillance in public areas.

In some municipalities around the United States, this type of alarm verification allows the property it is protecting to be placed on a "verified response" list, allowing for quicker and safer police responses. The first video home security system was patented on December 2, 1969 to inventor Marie Brown. The system used television surveillance.

In the mid-1970s, videotape became the first truly practical home-video format with the development of videocassettes, which were far easier to use than tape reels. The Betamax and VHS home videocassette formats were introduced, respectively, in 1975 and 1976 but several more years and significant reductions in the prices of both equipment and videocassettes were needed before both formats started to become widespread in households. Initially, film studios and video distributors assumed that the public would not want to buy
