The Sonic Cat Repeller incorporates a sophisticated PIR (Passive Infra Red) detection system which constantly monitors a fan shaped area of a 98 degrees arc up to a distance of 12 meters.
The protected area is over 120 square meters of unobstructed space. The Cat & Dog Repeller detects animals moving into this area and triggers a burst of continuously variable ultrasound, which sweeps a frequency range of 18,000Hz-24,000Hz to repel them.
Simultaneously the LED indicator on the front of the unit signals that it is now activated.
The use of battery power enables the repeller to be easily installed in areas of your garden without mains electricity, but the unit can also be mains connected by using an additional DC Mains Adapter.
