GSS_IIS 0 Posted August 21, 2017 Hello Forum! I have a general question about TVI and FM Video Transceivers. I have a customer that currently has an ancient PC-Based analog system that utilizes IFS VR1500 FM Video Transceivers over paired 62.5 Multimode Fiber to operate 8 Pelco P(!) RS485 PTZ cameras. They want to upgrade the entire system. I figure in the end since they're running paired fiber, I'll put in an IP System and be done with it, but out of idle curiosity... I know the nature of RS485 is pretty universal in terms of PTZ control, but my question is: Would a TVI system work over FM Transceiver, specifically the model mentioned above? I've briefly searched the web and could find no definitive answer beyond advertisements. :> Thank you! Edit: Turns out this model of VR1500s is over AM Frequency. Same question, though. For the record, the spec sheet for the VR1500 is here Share this post Link to post Share on other sites
