DCPA-4K Plus 5,000 Ft. Range Probe Driveway Alarm with External Output Capability

DCPA-4K Plus 5,000 Ft. Range Probe Driveway Alarm with External Output Capability


This is a probe-based (Magnometer) driveway alarm kit.  The probe based sensor is triggered when heavy metallic objects such as cars, trucks, etc., passes through the monitored zone.  The sensor then transmits a wireless signal, up to 5,000 ft. away to the receiver.  The receiver will then play a selected chime sound.  You can add transmitters and receiver to expand your system.

I Need a Driveway Alarm Kit that Detects Cars Only.

Many driveway alarm kits feature a passive-infrared sensor that is triggered when a combination of heat and movement are detected within the monitored zone emitted from the sensor.  While this is a great feature if you want notifications for people and cars, if you live in a wooded area or an area with many animals, or do not want notification if people pass through the zone, a magnetometer based probe sensor is a great choice.

This driveway monitoring kit will detect vehicles only that pass through the monitored zone and send a wireless signal up 5,000 ft. away to the plug-in receiver.  The sensor features a magnetometer probe you bury parallel to the driveway.  This creates a detection zone of 12′-13′.  50’ft of burial cable connects to the transmitter, which allows you to hide the transmitter and mount it to a post of near-by tree.  Additional burial cable lengths are available for an additional cost–please call or email for additional information.

When car passes through this zone, the transmitter will send a wireless signal up to 5,000 ft. to the receiver.  This is a line-of-sight distance.  Environmental factors such as terrain, metal, and building materials will diminish the signal, but with a range of up to a full mile, this tends to work for most customers.

The receiver featured in this kit will play 1 of 16 melodies when triggered.  This receiver is capable of working with up to 12 different transmitter/sensors at a time and the available melodies enable you to assign a different sound to each transmitter/sensor allowing you to distinguish which transmitter triggered the receiver.

The receiver plugs into a standard wall outlet and will sit on a flat surface or may be mounted on the wall.  The receiver features 2 x C-Form relays enabling you to integrate it with other systems, such as security systems, guard gates, etc.  In addition, the receiver features 1 x 12V DC output allowing you to connected devices such as a mini-strobe/siren, strobe lights, sirens, fire alarm bells, etc.

Receiver Features:

  • Each receiver will work with up to 12 transmitter/sensor.
  • Add as many add-on receivers as you want.  This allows you to spread receivers through-out your location to better distribute the sound.
  • The receiver has a volume control and will play one of sixteen different melodies.
  • Receiver plugs into a standard wall outlet.
  • Receiver is indoor rated only.
  • Range from transmitter to receiver is up t0 5000 ft.  Actual range will vary depending on specific environment.
