When looking at firmware versions for the Pro and Spectra Pro series there is usually two versions listed that look very similar. They will have the same version number and the only other difference is the word "arm" in the description
Pelco Cameras, Pelco Video Management
When looking for the firmware versions for the Professional series cameras
There is a need for two different versions. One is used by DU2 and Pelco Utilities and the other is used by the Web UI and is differentiated by the word " arm"
Know that if the word "arm' is in the description then it is to be used in the updates when doing them with the Web UI. This should be changed in the first quarter of 2016
