Surveillance method and apparatus
First Claim
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.

Abstract
A surveillance method includes: 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.

10. A surveillance apparatus comprising:
-
a first communicator configured to transmit or receive data to or from an outside of the surveillance apparatus at a first frequency; a second communicator configured to transmit or receive data to or from the outside of the surveillance apparatus at a second frequency lower than the first frequency; a timer configured to periodically generate a type-1 interrupt; and a controller configured to control transmission or reception of the data through the first communicator and the second communicator, and detect the interrupt, wherein the controller determines whether an event has occurred in response to the controller detecting the type-1 interrupt generated by the timer, and, in response to determining that the event has occurred, sends an event occurrence alarm to the outside through the second communicator and sends an image, corresponding to the event, acquired by an image sensor to the outside through the first communicator, wherein in response to the controller detecting a type-2 interrupt generated, the controller controls operation of at least one of the first communicator, the second communicator, the image sensor, and at least one detector configured to generate detection data, according to control information included in the type-2 interrupt, and wherein the controller is further configured to; in response to determining that the interrupt is the type-1 interrupt, switch a power-off state of at least one detector included in or connected to the surveillance apparatus to a power-on state, and in response to determining that the event has occurred based on the detection data, switch power-off states of the first communicator and the image sensor to power-on states. - View Dependent Claims (11, 12, 13, 14, 15, 16)

19. A surveillance apparatus comprising:
-
a first communicator configured to transmit or receive data to or from an outside of the surveillance apparatus at a first frequency; a second communicator configured to transmit or receive data to or from the outside of the surveillance apparatus at a second frequency lower than the first frequency; a controller configured to control transmission or reception of the data through the first communicator and the second communicator, and detect an interrupt; and an image sensor configured to acquire an image, wherein in response to the controller detecting a type-2 interrupt, the controller is configured to; control operation of at least one of the first communicator, the second communicator, the image sensor, and at least one detector configured to generate detection data, according to control information included in the type-2 interrupt; and determine at least one element, included in or connected to the surveillance apparatus, corresponding to the control information, and switch an operation mode of the determined at least one element or starts to supply power to the determined at least one element in response to the type-2 interrupt while maintaining an operation mode and a power state of elements other than the at least one element, and wherein the at least one element comprises at least one of the first communicator, the image sensor, and the at least one detector.
