Individual .fw.sig files can be thought of as individual sections or modules within the entire firmware. The naming convention is as follows:
<model>_<module>_<version>_<date>.fw.sig
The following files are all related to “Camera Upgrade” for the respective model because the second number value 0100 is the Module number.
