Video camera, setting method and adjusting method thereof

An adjusting method of a video camera for adjusting an installation position of the video camera on a stand, wherein the adjusting method comprises:

• obtaining an identification code of the stand;
• obtaining a first vector set of a gravity acceleration on three coordinate axes pre-stored in the video camera, wherein in the step of obtaining the first vector set, the first vector set is obtained according to a correspondence relationship between the first vector set of the gravity acceleration and the identification code;
• adjusting an angle, a direction or a position of the video camera;
• obtaining a second vector set of the gravity acceleration of the video camera on the coordinate axes by an accelerometer in response to an adjustment of the angle, the direction or the position of the video camera;
• determining whether the second vector set is the same as the first vector set;
• and
• concluding that the installation position of the video camera on the stand is adjusted completely when the second vector set is the same as the first vector set.
