Abstract:
1. An alarm apparatus, comprising: a first camera facing a first direction of a road, to capture images of the first direction; a second camera facing a second direction of the road, to capture images of the second direction, wherein a blind curve at which the alarm apparatus is fixed is connected between the first direction and the second direction of the road; a first output device facing the first direction of the road; a second output device facing the second direction of the road; a processor connected to the first camera, the second camera, the first output device, and the second output device; and a storage unit comprising a detecting module and a controlling module, wherein the detecting module stores a first instruction executed by the processor, thereby the processor receives the images captured by the first and the second cameras and determines what is the state of the road condition, the road condition includes three degrees, the processor determines the road condition is in a first one of the three degrees if there are more than a predetermined number of vehicles, pedestrians, or road-blocks on the road, the processor determines the road condition is in a second one of the three degrees if there is are fewer number of vehicles or pedestrians than the predetermined number on the road, and the processor determines the road condition is in a third one of the three degrees if there is no vehicle, pedestrian, or road-block on the road, and the controlling module stores a second instruction executed by the processor, thereby the processor controls the first and the second output devices to send out different alarming signals according to the state of the road condition.
