Abstract
A system and a method for monitoring a video communication device configured to monitor an activation state of a video capturing module are provided. A detection circuit is configured to detect an operation current input to the video capturing module. A control circuit is electrically connected to the detection circuit and determines whether the video capturing module is activated according to a magnitude of the operation current.
Claims7
A system for monitoring a video communication device, the system comprising:
- a video capturing module;
- a detection circuit configured to detect an operation current input to the video capturing module;
- and
- a control circuit electrically connected to the detection circuit and determining whether the video capturing module is activated according to a magnitude of the operation current,
- wherein the video capturing module comprises:
- the video communication device;
- and
- a transmission interface configured to output video communication data generated by the video communication device,
- wherein the control circuit periodically sends a request command to the transmission interface and determines a data traffic of the transmission interface according to a reply command transmitted back by the transmission interface,
- wherein when the data traffic of the transmission interface increases, the control circuit determines that the video capturing module is activated.
A method for monitoring a video communication device, the method comprising:
- detecting an operation current input to a video capturing module;
- and
- determining whether the video capturing module is activated according to the operation current, and correspondingly issue an alert signal to notify a user that the video capturing module is activated,
- wherein the video capturing module comprises:
- the video communication device;
- and
- a transmission interface configured to output video communication data generated by the video communication device,
- wherein the video communication device periodically sends a request command to the transmission interface, and determines whether a data traffic of the transmission interface is changed according to a reply command transmitted back by the transmission interface, and
- when the data traffic of the transmission interface increases, the control circuit determines that the video capturing module is activated.
A system for monitoring a video communication device, the system comprising:
- a video capturing module;
- a power module configured to provide an operation current to the video capturing module;
- a switch circuit coupled to the power module and the video capturing module, and selectively switched on or off according to an activation signal input by a user;
- and
- a control circuit electrically connected to the switch circuit, and configured to determine whether the video capturing module is activated according to whether the switch circuit is switched on or off,
- wherein the video capturing module comprises:
- the video communication device;
- and
- a transmission interface configured to output video communication data generated by the video communication device,
- wherein the control circuit periodically sends a request command to the transmission interface, and determines whether a data traffic of the transmission interface is changed according to a reply command transmitted back by the transmission interface, and
- when the data traffic of the transmission interface increases, the control circuit determines that the video capturing module is activated.
