Patent ID: 7909521

Claim:
A monitoring camera comprising: a) a camera portion that senses image of a object; b) a base; and c) a shooting angle change device that connects the camera portion and the base with magnetic force; wherein the shooting angle change device can change the shooting direction of the camera portion along X-axis, Y-axis, and Z-axis while the camera portion and the base are connected with magnetic force, wherein the shooting angle change device comprises; 1) a rotation guide surface that is formed on the base, wherein the rotation guide surface is curved; 2) a rotation surface that is formed on the camera portion, wherein the rotation surface contacts the rotation guide surface, wherein the rotation surface can be rotated relative to the base; 3) a magnet that is provided inside one of the camera portion and the rotation guide surface; and 4) an attaching member that is provided inside the other of the camera portion and the rotation guide surface, wherein the attaching member is made of magnetic substance, whereby the rotation surface of the camera portion and the rotation guide surface of the base contact with each other, wherein the magnet is installed inside the base, wherein a magnet installation recess is provided so that the magnet can be inserted from a side that is opposite to the rotation guide surface, wherein a magnetic shield plate is provided to prevent falling of the magnet that is installed in the magnet installation recess and to guide the magnetic force of the magnet toward the rotation guide surface, wherein the magnetic shield plate is made of magnetic substance.
