The present invention relates to an interface device (3) for video surveillance stations of the type comprising a video camera (1) and a positioning unit (2) for the video camera (1). The device (3) comprises a first port (403) for the connection to a remote terminal (4), a second port (503) for the connection to a video camera (1), a third port (603) for the connection to a positioning unit (2) for the video camera (1), and a microprocessor circuit (703) operatively connected to said three ports for transferring the commands received through the first port (403) to the second port (503) and/or to the third port (603). The microprocessor circuit (703) communicates with the video camera (1) and with the remote terminal (4) through two networks (103, 203) separated at physical or logical level, such that only the microprocessor circuit (703) is able to send the data received from a remote terminal (4) to a video camera (1) or to a positioning unit (2) and vice versa, while a remote terminal (4) is not able to communicate with a video camera (1) or with the a positioning unit (2). |
