1. A surveillance method performed by a surveillance apparatus, the surveillance method comprising:

  • an interrupt processing operation of determining whether an interrupt is generated and determining a type of the interrupt;

    a type-1 interrupt processing operation of, in response to determining that the interrupt is a type-1 interrupt, determining whether an event has occurred, and, in response to determining that the event has occurred, sending an event occurrence alarm to an outside of the surveillance apparatus using a second communicator, which transmits or receives data at a second frequency, and sending an image, corresponding to the event, acquired by an image sensor to the outside using a first communicator, which transmits or receives data at a first frequency higher than the second frequency; and

    a type-2 interrupt processing operation of, in response to determining that the interrupt is a type-2 interrupt, controlling the surveillance apparatus according to control information included in the type-2 interrupt,wherein the type-1 interrupt is an interrupt generated at a predetermined time interval, andwherein the type-1 interrupt processing operation comprises;

    in response to determining that the interrupt is the type-1 interrupt, switching a power-off state of at least one detector included in or connected to the surveillance apparatus to a power-on state, the at least one detector configured to generate detection data, andin response to determining that the event has occurred based on the detection data, switching power-off states of the first communicator and the image sensor to power-on states.
