Radar sensor-controlled wireless barking dog alarm/emergency alarm/doorbell with remote control

Radar sensor-controlled wireless barking dog alarm/emergency alarm/doorbell with remote control.

With EU 220V power plug adapter.

This electronic “dog” detects when there is a person nearby, behind a thick concrete wall and the like. Unlike other dog barking machines, this device uses radar beams to detect movement behind thick concrete walls.

For example, the machine can be placed behind the front door where it will bark like crazy (120 decibels !) when a person is near the dog barking machine/front door.

8 x 1.5V AA battery must be used (not included), or a 12V/1A adapter USB rechargeable (included).
