Abstract
There is provided a surveillance device capable of transmitting an operation history of an appliance and image data while suppressing an increase in data transmission cost. A surveillance camera includes a control unit controlling an operation of the surveillance camera, a light receiving unit receiving an infrared signal transmitted from a remote controller, converting the infrared signal into an electric signal and sending the electric signal to the control unit, a storage unit storing image data, an image capturing unit performing an image capturing operation and sending an image signal generated by the image capturing operation to the storage unit, a time keeping unit generating time information concerning the surveillance camera and sending the information to the control unit, and a communication unit outputting data sent from the control unit to an external device.
