Worn on a collar or mounted on a wall, the Dog Bio Security System translates barking into alarms for police or military. Bio-Sense Technologies spent two years capturing the sound waves of woofs and arfs, encoding them to be read by a digital signal processor. All dogs emit the same type of bark when they sense trouble. The device can distinguish this bark from a dog’s “Hello.” A consumer version costs $100. A high-end version costs tens of thousands of dollars but is still 25% the cost of video surveillance.

Dog Alarm System

Bio-Sense, in a breakthrough concept, has harnessed the natural intelligence and super-keen senses of the watchdog, and integrated them into an advanced security system.

Nature and technology integrated for complete security

Step 1 – An intruder approaches the dog’s territory, prompting the dog to bark in response.

Step 2 – Bio-sense sensor picks up the signals, analyses them, and decides on a security alert

Step 3 – The home alarm system is activated, and/or a telephone message is sent to the homeowner or the security center

Field Proven Performance

Bio-Sense’s extraordinary technology is successfully in operation at several governmental agencies including the Israeli Air Force and Prison Service, as well as at commercial sites and private residences. In short, DBS is a highly practical and costeffective method. It combines the dog, as BioSensor, with electronic monitoring and communication systems, to offer a complete security solution.

The Technology

DBS innovative technology is based on advanced proprietary algorithms that monitor the dog’s barking and other sounds to determine the state of the dog. DBS identifies the dog’s natural instinctive reaction to emergency events, so no preliminary training is required. No matter what type of dog, age or size, the algorithms distinguish whether the dog is responding to a routine event or to an intruding stranger.

Versatile Applications

DBS sensor is wall or fence mounted in the dog’s vicinity. It can either be linked to an existing alarm system or used as a stand-alone alarm system - paging the owner or the security center telephone. An alternative style of sensor, mounted to the dog’s collar, functions in the same manner as the wall-mounted unit.
