First Claim
Patent Images
1. A camera management device coupled to a network camera via a network, comprising:
- an image receiving unit that receives image data projected by the network camera and including control information for controlling the network camera from the network camera;
a control information extracting unit that extracts the control information from the image data received by the image receiving unit;
a mode storage that stores a state of a control mode which is a mode for controlling the operation of the camera management device;
a control transmitting unit that transmits a control command according to the control information to the network camera via the network when the control mode is on;
an upper limit frequency storage that records an upper limit frequency by which the control command is transmitted;
a frequency storage that stores a frequency by which the control command is transmitted after the control mode is turned on; and
an authenticating unit determines whether or not a frequency by which the control command is transmitted exceeds the upper limit frequency and turns off the control mode when the authenticating unit determines that the frequency by which the control command is transmitted exceeds the upper limit frequency.
