Directed Electronics (DEI) is one of the most recognized companies in the automotive aftermarket security and remote start industry. Founded in 1982 and headquartered in Vista, California, DEI built its reputation by developing advanced vehicle alarm and convenience systems for specialty retailers and professional installers. Over the decades, the company has grown into a major force in 12-volt electronics, distributing multiple well-known brands and technologies throughout North America and internationally. DEI was later acquired by VOXX International, further expanding its reach within the automotive electronics market.
The company’s flagship brand is Viper, which has become one of the most recognizable names in vehicle security and remote start systems. Viper built its reputation on high-performance alarm systems designed to deter theft with features like shock sensors, sirens, and immobilization technology. Over time, the brand expanded into remote start systems, allowing drivers to start and climate-control their vehicles before entering — a feature that has become especially popular in extreme hot and cold climates.
Viper also helped push the industry forward with connected car technology through its SmartStart system, which enables users to control their vehicle from a smartphone app. Today, Viper products remain a benchmark for premium aftermarket security and convenience solutions.
