An external bellbox is a security device commonly used in alarm systems, designed to alert individuals to a triggered alarm. Typically mounted on the exterior of a building, it features a loud siren and often includes flashing lights to deter intruders and notify nearby residents. The visible presence of a bellbox can act as a deterrent to potential burglars, signaling that a property is protected by an alarm system. Some models may also incorporate features like remote monitoring or connectivity to a central alarm system.
The ADT logo design was created for the sake of being simple. It was created to be easy for branding the logo on security equipment such as cameras and the bellbox outside of homes.
