Hello, I have 2 Kalatel CyberDome series PTZ cameras. I am having issues with one of them. I have intermittent video loss, in 5 to 6 second spans while in tour mode. If I have the PTZ sitting still, it will record all day everyday, but in tour mode I lose video for 5-6 seconds at a time at a rate of once or twice an hour. When I lose the video feed, the tour remains in motion. Therefore I assume it is not a power issue. Everything between the 2 ptz's is identical; length of cable, setup, everything. 24VAC power, coaxial cables with BNC connectors at the dome and the dvr, RS422 line running from the back of the Digiplex IV matrix spliced in with a KTD-405 controller pad, and an RJ45 connector jack from the camera to the power/video lines. As mentioned I have control of the camera with the joystick, and it maintains in motion during video loss. I just do not know where to begin with finding what the problem is. Any suggestions? BTW, the video loss is never at the same point in the tour, and the loss is not in equal times between them. Thank You.

So as I mentioned earlier, I have two PTZ's and only one of them is having this problem. Here is what I did. I rewired them both, by swapping the wiring. I used the power and video feed from the good PTZ and wired it into the problematic PTZ and used the wiring from the problem PTZ on the good one. I expected the problem to swap between PTZ's but it didn't. I still have the same problems on the PTZ. Does that make the source of the problem internal to the PTZ?

thank you so much for your suggestion. I probably never would have fixed it, because i was assuming it could not have been a power issue. But thank you, I will try it out and if it doesn't work I'll post come back. But thank you for your time. -Tyler

The maximum it will need is 24 VA, with a minimum of 16 VA. I apologize for the confusion here.... running to the PTZ's is 18 Gauge wire at 169 feet wire length. 22 Gauge wire is what powers the stationary cameras throughout the rest of the building. I apologize for informing incorrectly.

I have 22 Gauge wire running 169 feet total. They require 16 VA minimum. I have 22 VA at the module. Allowable voltage range is 20 to 28 Volts. I do not know the watt ratings, just the volt ratings.
