Colin Smith 0 Posted August 24, 2022 I am trying to work out what is needed to get one of these camera's, HERNIS PT9W, working in conjunction with the HERNIS control system keyboard, OK450L. Does it require the proprietary video matrix, which is prohibitively expensive. I am hoping someone here may be familiar with these camera systems.
