We are consistently losing control of 2 PTZs using a short (.5km) radio shot and I'm very perplexed. Everything tells me this set-up should be working flawlessly. We have at least 6 other radio shots set up at far greater distances that do work flawlessly. In the control room, our accudome controller sits on a table within half an arms length of 2 landline phones and a hand-held radio. Is it possible these other electronics are disrupting our controller/keyboard signal. The controller is hard-wired using cat-5 cable between the keyboard and transmit box. The cable is unsheilded at the connection going into the keyboard for approximately 1.5 inches. I'm really grasping at straws on this one.
