An image capturing apparatus includes: a sensor; a camera; an image processor; a first communicator operatable in one between a first status and a second status that consumes less power than the first status; a second communicator having a lower data transmission rate than the first communicator; and a controller configured to make a request for whether to take an image with the camera to an external apparatus through the second communicator if the sensor senses an object while the first communicator is in the second status, control the image processor to generate the data of the image taken by the camera in response to an instruction received by the second communicator, and control the first communicator to switch over to the first status so that the data of the image are transmitted to the external apparatus through the first communicator.
