1. A monitoring system for remotely monitoring a state of pole-mounted equipment in a power distribution or transmission grid, the pole-mounted equipment comprising an indicator device configured to present state information indicative of a state of the pole-mounted equipment, wherein the indicator device comprises a fixed part and a moving part that is movable relative to the fixed part from a first static position indicative of a deactivated state to a second static position indicative of an activated state, the monitoring system comprising:
a status monitoring device movable via a drive or propulsion system, wherein the status monitoring device is configured to obtain the state information from the indicator device when located within a communication range of the indicator device;
wherein the state information is indicated by the moving part of the indicator device being in one of the first static position relative to the fixed part or the second static position relative to the fixed part, and wherein the status monitoring device comprises an optical detection device for determining the state information based on optically detecting whether the moving part of the indicator device is in the first static position relative to the fixed part or the second static position relative to the fixed part.
