A method for controlling a camera through a Multi-Hop-based wireless sensor network includes: sensing whether an event occurs or not in a corresponding area and transmitting position information on the corresponding area and type information on the event, converting the received position information on the event into a movement control signal for the camera, calculating camera driving values in a left/right direction and an up/down direction using the converted signal, controlling a zoom-in operation of the camera lens using the calculated camera driving values according to the received event type and photographing an object located in the corresponding direction, and transmitting the photographed images over the outer network.
