Radio Call Boxes and Accessories
A call box is a durable, often weatherproof enclosure containing a direct-line radio or telecommunications device. Used across industries for decades, call boxes offer remote personnel or the public a way to contact a central office, security team, or dispatch center. They’re a staple in motorist assistance programs, transit terminals, parking lots, and on large campuses where fast response is critical.
The history of call boxes dates back to the early 20th century when they were installed as wired telephones along highways, city streets, and industrial sites. Police call boxes became widespread in urban areas during the 1920s–1940s, offering beat officers a way to check in with dispatch. Over time, their use expanded to fire departments, transportation authorities, and even military bases. As technology evolved, radio-based systems began to replace hardwired lines, enabling wireless communication over VHF and UHF frequencies. Today’s models integrate two-way radio, cellular, and even IP-based technologies for greater coverage and functionality.
Call boxes come in both wired and wireless formats. Wireless call boxes often operate on VHF or UHF business band frequencies and may be integrated with an organization's existing two-way radio system. Many models are compatible with standard portable or base radios from Motorola and other leading brands, and certain units are FCC license-free for simplified deployment.
