Zusammenfassung:	The invention relates to the technical field of camera control, and discloses a hard disk video recorder and a power supply control method. The hard disk video recorder comprises a power detection module, a controller, a power supply control module and a power supply module. The controller is used for receiving a power signal obtained after the power detection module measures the power of the camera, and sending a first control signal to the power supply control module under the condition that the power signal represents that the power of the camera is abnormal, so as to control the disconnection between the power supply input end and the power supply output end of the power supply control module; and under the condition that the power signal represents that the power of the camera is normal, a second control signal is sent to the power supply control module so as to control the conduction between the power supply input end and the power supply output end of the power supply control module. Thus, under the co
