What is proposed is a security system, in which, for example at a bank counter, when a cheque (S) is presented the customer and the cheque are recorded photographically. In order to compensate the differing object range of the person and the cheque in relation to the camera (K), there is provided a focusing device (5, US), by means of which the recording distance can be changed over automatically. <IMAGE>
