A shovel includes a lower running body and an upper turning body that is turnably provided on the lower running body. An engine is mounted on the upper turning body. A hydraulic pump is driven by the engine to discharge an operating oil. A hydraulic actuator is mounted on the upper turning body. A control device controls operations of the shovel. An entering object detection device detects a position of an entering object in a monitoring area of said shovel and outputs a detection signal indicating the detection position of said entering object.
