Our Vehicle Alert Products are designed to do just that - alert you when a vehicle enters your property or drive. We have two systems for this purpose, one is the air powered option, and another is a wireless system.
The air hose system (vehicle alert bell, buzzer, or chime) option is best remembered by the "ding-ding" sound heard at gas stations for years. This system is commonly used for long residential driveways, drive-thru businesses, and service centers as well as gas stations. The individual parts can be used for new construction or repairing of existing systems.
