A monitoring system includes a camera module configured to photograph a subject, a laser distance sensor configured to sense a distance to the subject, the laser distance sensor being arranged in a line with the camera module, and a processor configured to acquire a first angle and a first sensing value of the laser distance sensor in response to an event, calculate a first distance between the camera module and the subject by using the first angle and the first sensing value, calculate a second angle by using the first distance, a laser angle of view of the laser distance sensor, and a laser angle of view length of the laser distance sensor, rotate the laser distance sensor up to the second angle when a difference between the first angle and the second angle exceeds a predetermined range, and acquire a second sensing value of the laser distance sensor.

Monitoring system and operation method thereof

Disclosed is a foldable frame which can be widely applied to instant tents which are easily installed or uninstalled and have a rectangular or square bottom surface of various sizes. With a head () of the foldable frame, a top plate () and a bottom plate () are engaged to each other in such a way that the center portion can be rotated in a state in which an upper ends (one end of the first rod) of the poles are respectively engaged to the rod engaging holes (andand') of the top and bottom plates (and) in a diagonal direction, so that the top and bottom plates of the head are automatically rotated according to various shapes of the rectangular or square bottom surface, thereby forming an intersection angle between the pole coupling portions formed on the head (an angle of intersection between both pole coupling portions of the head). Therefore, the foldable frame can be widely applied to the instant tent, regardless of the rectangular or square shape of the bottom surface of various sizes.

Foldable frame for instant tent

The present invention relates to an automatic tent frame capable of preventing an upper coupler and a lower coupler from being rotated with respect to each other or preventing given gaps from being generated on the coupled portions of the upper coupler and the lower coupler even in a case where an automatic tent is not unfolded to its original shape by the reduction of the restoring force of an extension spring and thus falls down due to external impacts like wind, thus preventing support poles supporting main poles from being damaged to extend the life span of the automatic tent frame, and capable of reducing the length of a pipe module, while allowing the pipe module to have the same functions as in conventional one, thus upwardly lifting an outer surface of the automatic tent by the reduced length to increase the interior of the automatic tent by a maximum height.
