Abstract
The utility model discloses identification equipment having detachable cameras. The identification equipment has cameras with insertion pins; an identification module having pin holes connected in matching with the insertion pins; a control chip installed in the identification module; and a switching circuit installed in the identification module and used for transmitting signals between the camera and the control chip. The switching circuit is connected with the pin holes and pins of the control chip. In terms of the identification equipment in an embodiment, when some camera fails, the camera can be replaced in time, and the circuit on the identification equipment needn't be maintained, the replacement is easy, and the maintenance efficiency is improved. Starting of a part of the plurality of cameras can be realized, so that images of shooting areas of the part of cameras can be collected. Particularly for face identification equipment, a plurality of installed cameras have different shooting areas, and images of a plurality of areas can be obtained. Thus the collection area is expanded, and the blind area of image collection in the process of face identification is eliminated.
