Soundy 1 Posted August 6, 2012 Pretty much all analog PTZ cameras will inherently have RS-232/422/485 support - be difficult to control them remotely otherwise. RS-485 is just the electrical interface used; where you run into compatibility problems can be in the protocols "spoken" - Pelco D, Pelco P, etc. Fortunately almost all cameras AND DVRs support Pelco D/P in addition to their own - kind of a "universal" language.
