Abstract
A gateway of a surveillance system, the gateway includes: a communication module configured to communicate with a plurality of network cameras including a first network camera and a second network camera; and a processor configured to recognize a motion of a subject based on event information transmitted by the first network camera and to transmit subject information generated based on the motion of the subject to the second network camera.
Claims5
A surveillance system, comprising:
- a first network camera configured to capture an image and detect an event;
- a second network camera;
- a gateway comprising:
- a communication module configured to communicate with the first network camera and the second network camera;
- and
- a processor configured to recognize a motion of a subject based on event information transmitted by the first network camera and to transmit subject information generated based on the motion of the subject to the second network camera, wherein:
- the second network camera is configured to, based on the subject information received from the gateway, change an operation mode to a standby mode in which the second network camera is configured to acquire a low-quality image;
- the second network camera is configured to, based on detecting the event in the standby mode, change the operation mode to an active mode in which the second network camera is configured to acquire a high-quality image;
- the subject information comprises at least one selected from among a moving direction of the subject and a moving speed of the subject;
- the first or second network camera is configured to capture an image of a surveillance region and perform at least one operation selected from the group consisting of panning, tilting, and zooming;
- and
- the processor is further configured to control the first or second network camera to perform the at least one operation selected from the group consisting of panning, tilting, and zooming with respect to the moving direction of the subject,
- wherein the first network camera is configured to, based on detecting the event in a sleep mode, change the operation mode from the sleep mode to the active mode,
- wherein the second network camera is configured to, based on the subject information received from the gateway, change the operation mode from the sleep mode to the standby mode, and
- wherein an event sensing period to detect the event in the standby mode is shorter than that in the sleep mode.
