Abstract: A surveillance camera has a sensing module, a micro-control unit (MCU) and a real-time clock (RTC) unit. The sensing module records original images. The MCU is connected to the sensing module and stores multiple time settings and a smart timer process. The MCU executes the smart timer process to operate the surveillance camera in a color mode, a monochrome mode or an auto mode based on the time settings. In the color mode, the surveillance camera records color images. In the monochrome mode, the surveillance camera records monochrome images. In the auto mode, the surveillance camera selectively records color images and monochrome images based on a variation between light level of the original images and a predetermined light level. Therefore, the surveillance camera can be set to operate in specific mode based on requirements. The surveillance camera is more flexible and convenient than conventional surveillance cameras.

Abstract: A defogging device for a surveillance camera has a heating element, a circuit board and a power cord. The heating element is mounted over the lens of the surveillance camera. The circuit board compares ambient temperature to a preset temperature, activates the heating element and has a power input terminal, a power output terminal and a temperature sensor. The temperature sensor is mounted between the power input terminal and the power output terminal and senses ambient temperature. When the ambient temperature is above the preset temperature, the circuit board activates the heating element. The power cord is connected to the circuit board and the heating element and transmits power to the heating element from the circuit board. By activating the heating element during periods of cold ambient temperature, the defogging device removes fog and frost from or keeps fog and frost from forming on the lens of the surveillance camera.
