 Mount codes are unique across all sites, including seismic, GNSS, and other sites. They are found in the [network/mounts.csv](https://github.com/GeoNet/delta/blob/main/network/mounts.csv) file.
 
-Mount codes are 4 letters. In many cases, the first two letters give an indication of where the site is (i.e. they will be an abbreviation of a significant local geographic feature), and the last two letters give a sub-location, particularly where there are multiple mounts in the same area, e.g. WINR is at White Island (WI) on the north rim of the crater (NR).
+Mount codes are 4 or more letters. As of 2026, permanent camera sites are named with a C suffix to indicate their nature. This allows distinction of camera sites from GNSS at the same location where they would otherwise have equivalent station codes.
 
-In some cases, the mount codes do not follow this pattern, typically for historical or other reasons, e.g. TEMO is Taranaki Emergency Management Office, and KAKA is Kakaramea.
+Mount codes are named for ease of distinction and reflect either (or both) camera location or monitoring subject cues. There is no fixed convention for camera mount codes although a few are used consistently:
