Abstract
A water sprinkler based deterrent system is used to deter entry into landscaped areas by undesirable intruders. The system incorporates an infrared detector combined with a control circuit that is adapted to be powered from a wide range of power supplies. In this manner, the system can be easily integrated into a variety of landscape environments, including those that may or may not include a preexisting sprinkler controls system.
