Abstract
An animal deterrent system for deterring animal intrusion into a specified area using an oscillating ultrasonic tone. The system includes a weatherproof housing containing an infrared detector for detecting the presence of an animal. To identify relevant intrusions, a count of the number of detections is maintained. After the count reaches predetermined number of infrared signals within a predetermined amount of time, an oscillating ultrasonic deterrent signal is generated to distress the animal and deter intrusion into the protected area. A deterrent timer activates the ultrasonic deterrent for a predetermined amount of time. A mounting stake for deploying the system in remote outdoor locations includes an anti-rotation mechanism, to prevent misalignment as a result of incidental contact.
