A helmet having a range finder(RF) camera is provided to be worn by a riot police or an agent who needs to get information about all types of accidents or riots without letting others recognize that he/she is taken pictures. A helmet(10) has a hole(11) formed at the center of the front part of the helmet. Thus, a camera lens of a camera(12) built in the helmet allows a user to take necessary pictures of a riot. The camera as well as a wireless module(13) for transmitting photographed images to a remote data collection center is placed in a space between an inner head band(17) and an outer skin of the helmet. Operations of the camera and the wireless module are carried out by a battery voltage provided from a battery(14). The power supply by the battery is determined by serial circuits of a main switch(15) and a helmet switch that is automatically turned on as soon as the user puts on the helmet. |
