RMTeK has been working closely with the rail transport industry to implement a system for providing SMS notification of rock-falls along track and provide real-time vision to verify track conditions. 

The pictures below show a section of track with a corner 200 metres distant.  The first picture is a wide view of the track section, the second is zoomed-in to provide close-up detail of the corner.

The use of RMCam has been a great success in this situation, since installation the camera has been frequently accessed providing vital business and safety information.
