Claim:
1. A security system for securing the surroundings of at least one object having a first safety laser scanner with which a first defined reference target is associated and having a second safety laser scanner with which a second defined reference target is associated, wherein a safety laser scanner has: a light transmitter; a light deflection unit for a periodic deflection of the light into a scanning plane; a receiver for providing received signals in dependence on light remitted at articles present in the field of vision of the scanner; and an evaluation unit for evaluating the received signals with respect to the angle and a distance of the article and for providing a safety signal, characterized in that the scanning planes of both scanners are coplanar and the first scanner forms the second reference target and the second scanner forms the first reference target, wherein the evaluation unit comprises a scanner recognition unit with which each scanner can recognize from its received signals which of the detected reflections emanate from reflections of its own light in the respective other scanner.
