Bubba’s BHS-DA-20 model features a PIR motion sensor that will detect people, animals and cars.
The alarm systems include 1 transmiter and 1 receiver. Batteries are sold separately (3 AAA batteries and 3 C batteries). Optionally, you may also purchase an adaptor for the receiver since this is not included in the package.
When the PIR sensor detects movement, a signal will be sent to the receiver. You will then be alerted by either a sound, an LED light, or both.
If possible, install the sensor in an area protected by heavy rain and wind.
Bubba’s BHS-DA-20 wireless driveway alarm is an inexpensive alarm because of its inferior quality. Even though the alarm uses a PIR (passive infrared sensor), the sensor it’s cheaply made and false alarms constitute a big issue. As an alternative, take a look at the Guardline GL2000 if you’re looking for a driveway alarm that will detect people and vehicles. If you would like to be notified only when a car pulls into your driveway, I recommend the Dakota 2500.
