Desco Audio & Video (Desco Electronics) has worked in audio and video in the South Sound since 1969, from an office on Harrison Avenue in Olympia, for homes and businesses. Its residential work includes home theaters, home audio and video, smart home automation with platforms such as Control4 (lighting, climate, audio and security from one app, touchscreen or keypad), intelligent lighting control, motorized shades, home networking and outdoor entertainment.
Its security page covers home security cameras, smart locks and keyless access control, and alarm systems with 24/7 professional monitoring; the site does not say whether that monitoring is its own or a contracted center, so it is not listed here as an alarm company.
