Abstract
A surveillance method performed by a surveillance apparatus is provided. The surveillance method includes determining whether an event has occurred based on detection data; in response to determining that the event has occurred based on the detection data, transmitting a first wireless communication to an outside of the surveillance apparatus by using a second communicator at a second frequency and switching a power-off state of a first communicator to a power-on state; and transmitting a second wireless communication, corresponding to the event, to the outside by using the first communicator at a first frequency higher than the second frequency.
Claims22
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.
A surveillance apparatus comprising:
- a first communicator hardware configured to transmit or receive data to or from an outside of the surveillance apparatus at a first frequency;
- a second communicator hardware configured to transmit or receive data to or from the outside of the surveillance apparatus at a second frequency lower than the first frequency;
- and
- a controller configured to, in response to determining that an event has occurred based on detection data:
- switch a power-off state of the second communicator hardware to a power-on state,
- transmit 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 the second frequency,
- switch a power-off state of the first communicator hardware to a power-on state;
- and
- transmit a second wireless communication, corresponding to the event, to the outside by using the first communicator hardware at the first 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.
