The invention concerns an interactive audio-visual system between a local scene and a remote scene, comprising at least a device ( 1 ) for producing images of the local scene and a device ( 2 ) for reproducing the image of the remote scene in an image plane ( 1 ). The image sensing device ( 1 ) comprises at least a camera ( 12 ) and a mirror ( 11 ) capable of reflecting on said camera ( 12 ) the parallel rays derived from the local scene and perpendicular to the image plane ( 1 ). Preferably, the mirror ( 11 ) is concave and has a focal point and the camera ( 12 ) is located in the proximity of the focal point of said mirror ( 11 ).
