PURPOSE: A monitoring sound wave attacking device using a directive sound wave transmitting speaker is provided to form a structure for opening/closing the front side of the device, thereby blocking dust such as rain or yellow sand. CONSTITUTION: A main body(100) includes a directive speaker(110). The directive speaker transmits a high power sound wave to a remote place by preventing spread of a sound wave. A laser point(120) is installed on the outside of the main body. The laser point points a remote target using high power laser. A search light(130) is installed on the outside of the main body and has strong directivity. The search light has high brightness and long lifetime. The search light is made of LED bulbs. A camera(140) is installed on the outside of the main body. The camera takes a photograph during day. An infrared camera(150) takes a photograph at night. |
