Abstract
A camera includes a bracket, a lens base, a lens, a filter, a circuit board, and a photosensitive, chip. The bracket defines a first receiving space, a second receiving space, and a through hole. The through hole is in communication with the first receiving space and the second receiving space. The lens is mounted on the lens base. The filter is received within the first receiving space. The circuit board is mounted on the side of the bracket defining the second receiving space. The photosensitive chip mounted on the circuit board faces the through hole. The bracket includes a heating member and two conductive circuits. The filter is mounted on the heating member such that a periphery of the filter is in contact with the heating member. Each of the two conductive circuit layers is electrically coupled between the heating member and the circuit board to heat the filter.
