Abstract
The present disclosure relates to an imaging device having a night vision mode. The imaging device has a lens being capable of perform imaging according to received light and an infrared LED being capable of emitting infrared light as a light source for the lens in a night vision mode, both being controlled by a control circuit. The lens is allowed to perform imaging when the control circuit is turned on, and the lens is prohibited from performing imaging when the control circuit is turned off. The imaging device also has a switch and a baffle, the position of which triggers the switch to turn on and off the control circuit. The imaging device provides privacy protection and avoids the reduction of the lifespan of the infrared LED.
