VIDEO CAMERA
First Claim
1. A video camera comprising:
- a first temperature sensor;
a control logic circuit;
a main system;
a heating module;
a fan; and
a power supply,wherein after the power supply supplies power to the video camera, the first temperature sensor comes to be active, when the temperature sensed by the first temperature sensor is less than T1, the first temperature sensor outputs a control signal to the control logic circuit, which activates the heating module and the fan and prevents the power supply from supplying to the main system, and when the temperature sensed by the first temperature sensor is greater than T1, the first temperature sensor outputs a control signal to the control logic circuit, which enables the power supply to supply to the main system.

Abstract
A video camera includes a first temperature sensor, a control logic circuit, a main system, a heating module, a fan and a power supply. After the power supply supplies power to the video camera, the first temperature sensor comes to be active, when the temperature sensed by the first temperature sensor is less than T1, the first temperature sensor outputs a control signal to the control logic circuit, which activates the heating module and the fan and prevents the power supply from supplying to the main system; and when the temperature sensed by the first temperature sensor is greater than T1, the first temperature sensor outputs a control signal to the control logic circuit which enables the power supply to supply to the main system and inactivates the heating module and the fan, and therefore, a normal activation and stable operation of the video camera at low temperatures are ensured.
