PROBLEM TO BE SOLVED: To provide an easy-to-use and efficient detonating sound device that can exert an effect for countermeasures against damage by animals such as monkeys, deer, wild boars, raccoons, badgers, Paguma larvata, raccoon dogs, and bears that break into fields, animals such as ownerless cats and crows that rummage in garbage stations in a residential area, and burglars and thieves.SOLUTION: There is provided an "infrared ray sensor type intimidation device for animal damage prevention" which is not actuated at all in a stand-by state, but generates a detonating sound only when an object person comes close so as to maximize an intimidation effect. The inexpensive device can be easily installed even in a place with no 100 V outlet, and, irrespective of location, can scare off animals and suspicious persons easily.SELECTED DRAWING: Figure-1 |
