cctvfl 0 Posted April 17, 2007 Hello Could someone explain what the terms mean that some PTZ's use a couple of the manuals I have for the PTZ s are not written with a full expanation; I'm sure thats because they are translated and re-written for the states. For example What is Frame Scan ? Call v.s. presets ? these are just a few Thanks for your help in advance... Share this post Link to post Share on other sites
