RIS-2712-RST Iss 1.1
On-Train Camera Monitoring Systems
Summary Of Changes
Following a discussion with a supplier and subject matter expert in the field of camera lens', along with further research, it was discovered that the inclusion of focal length as a means to compare different camera solutions may be problematic when being interpreted by industry and could mislead users of the RIS when obtaining camera systems based on focal length values to provide a particular field of vision. It was therefore considered that the removal of focal length as a parameter for consideration in this RIS was necessary to ensure appropriate interpretation of the guidance meaning.
Section 2.11.4 has also been added to this RIS to provide guidance on cloud based storage systems. This was added following a request for help (20-REQ-38) from Angel Trains which discussed the inclusion of such systems in the standard to remove the necessity to store data on-board a train for 31 days if cloud storage is available instead.
