Doorbell Air Hose Alarm
Driveway Bell - Driveway Doorbell
Driveway Pressure Sensor Wireless Driveway Alert
Changes in air hose pressure trigger the driveway pressure sensor; as a car rolls over the hose, the increased air pressure within the hose triggers the sensor transmitter.
Rubber Hose Driveway Alarms are pressurized rubber hoses, which are laid on the driveway. They trigger the driveway alarm transmitter and a wireless signal tells the receiver to 'alarm' when there is pressure on the tube. These driveway bell sensor alarm systems are best for hard surfaces. These sensors are ideal where the detection of people or animals is not desired, and where winter conditions will not disrupt the functionality of the rubber hose.
