1. A surveillance method performed by a surveillance apparatus, the surveillance method comprising:
determining whether an event has occurred based on detection data;
in response to determining that the event has occurred based on the detection data,
switching a power-off state of a second communicator hardware to a power-on state,
transmitting a first wireless communication to an outside of the surveillance apparatus by using the second communicator hardware, of which a power state is switched, at a second frequency, and
switching a power-off state of a first communicator hardware to a power-on state; and
transmitting a second wireless communication, corresponding to the event, to the outside by using the first communicator hardware at a first frequency higher than the second frequency,
wherein power is completely shut off from the second communicator hardware in the power-off state of the second communicator hardware such that communication with an external apparatus at the second frequency is not possible.
