Weather resistant

larry contains special mesh materials inside the enclosure to protect the speaker and siren ports from the elements – do not puncture the mesh.  The rubber dust cover will protect the main controls; however, larry is not waterproof.

WiFi connection

Larry is equipped with the latest in embedded WiFi technology with the connection range boosted by a special antenna. The actual connection distance between larry and your smartphone will depend on the operating conditions. If you are out of range of connection, no worries, larry will continue to function independently and will provide updates when you are back in WiFi connection range.

3D radar sensing

Larry incorporates exclusive radar sensing technology to allow the user to select 3 protection areas depending on the size of the area to watch:

  • Small area is 3 ft x 6 ft  (the area of a couple bicycles or motorcycle)
  • Medium area is 6 ft x 9 ft  (the size of a typical truck bed, or car interior)
  • Large area is 15 ft x 20 ft  (typical area in front of an RV, camp site, or picnic area)

These zones are approximate sizes and can vary depending on the operating conditions. The radar is able to “see” through most materials, except metal. When something triggers the alarm inside the selected protection area, an alert will be sent automatically to your smartphone.

Positioning larry

Place larry facing the direction of the area you wish to protect with the camera lens unobstructed. You can place the sensor portion behind most materials except metal, but it works best in free air. The protection area starts immediately from the larry device projecting a 3D radar virtual boundary according to your selected size.

Larry can be placed anywhere

Velcro strap included to hold larry to any pole, handle bar, tree etc. Adjustable suction cup mount allows you to position larry to nearly any smooth flat surface.

Secure larry

Thread the flexible cable lock into the metal insert located on the side of larry to secure your device.

Camera operation

Larry utilizes a high speed 2 megapixel, wide angle camera in burst mode to capture 15 images of anything triggering detection inside the selected 3D radar area.
