Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non‐governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Tractors and machinery for agriculture and forestry —
Camera interface between tractor and implement — Part 1:
Analogue camera interface
1 Scope
This document defines the physical link between analogue cameras mounted on implements and
operator terminals or monitors installed in tractor cabins. The interface supports up to two analogue
video streams and provides electrical power to the cameras. It is designed to be installed inside the cab
of agricultural equipment.
