Abstract: An inspection system comprising an inspection and/or maintenance device and a monitoring device is provided. The inspection and/or maintenance device is operationally connected to the monitoring device via a wired communication connection, and the inspection and/or maintenance device has at least one image recording system, the at least one image recording system provides digital video data and the inspection and/or maintenance device has a transmitting device which is operationally coupled to the at least one image recording system and to the communication connection, and the monitoring device has a receiving device which is operationally coupled to the communication connection. The transmitting device and the receiving device are adapted to transmit the digital video data at least via a sub-section of the communication connection in an analog manner according to an AHD standard. Also provided is a method for transmitting digital video data is provided.

Abstract: An inspection or maintenance system is provided comprising an electrical interface, wherein the inspection or maintenance system comprises an inspection or maintenance unit and an external unit, which can be coupled to the inspection or maintenance unit electrically. The inspection or maintenance unit comprises a housing and the housing has a first electrically conducting portion and at least a second electrically conducting portion. The electrically conducting portions are electrically isolated from each other, the external unit comprises a first electrical contact and at least a second electrical contact, wherein the electrically conducting portions and the electrical contacts are configured such that the first electrical contact can be brought into electrical contact with the first electrically conducting portion and the at least one second electrical contact can be brought into electrical contact with the at least one second electrically conducting portion.
