1. A method for moving detection, comprising:

  • a service server acquiring a first surveillance image captured by a camera at a preset first moment, and calculating a first moving angle of a pan-tilt;

    acquiring a second surveillance image captured by the camera at a preset second moment, and calculating a second moving angle of the pan-tilt; and

    determining by comparison whether common images in the first surveillance image and the second surveillance image are consistent according to the first moving angle and the second moving angle;

    if inconsistent, triggering a moving detection alarm;

    wherein a time interval between the preset second moment and the preset first moment is less than (a viewing angle of the camera)/(a moving speed of the pan-tilt*2).
