Hello,
Recently, I purchased the above PTZ to go with my Zmodo ZMD-DD-SBN4. However, it seems that I can't get it to work properly. It will work for a few seconds using the moving controls in the DVR then it will become unresponsive, go out of focus, or move randomly. I have matched the my DVR to the specifications of the PTZ's default address, protocol and baudrate. I have also talked nice to the PTZ and well as in a harsh voice to hope it motivated it. All to no avail. I was thinking maybe it was some sort of an issue with communication from the PTZ to the DVR. Also, I have tried changing the baudrate, address, and protocol hoping the issue of unresponsiveness would improve, but no such luck.
Any ideas?
Thanks,
There are several possibilities. It could be a defective camera, it could be a bad RS485 port on the DVR, it could be faulty wiring. Do you have another DVR to test the camera with to see if you get the same symptoms? If not, do you have a PTZ controller to connect it to? Otherwise, you might have to return the camera for us to test it.

I'm just a forum memeber, not official support. If you had your wires backwards on the dvr, the camera wouldn't move at all. So it's probably not that. I notice the camera doesn't come with a power supply. Are you using the proper rated one for the camera? How long is the distance from the dvr to the camera? If the run is very long you'll have voltage drop and the camera will be under powered, causing issues. Also just a bad power supply can make a ptz flake out too. You could also try rebooting the dvr. Sometimes doing that resets communication to the ptz. You could try rebooting the camera as well, but it might not help. Could be a bad camera, a poor or improper rated power supply, or the zmodo dvr isn't all that good with ptz's. Good luck. Like I said- just random thoughts from me, nothing official.

A couple further things. Like Daniel suggested- make sure your wires are secure in the dvr. the hookups on dvrs for 485 can be finiky and cheap. Make sure you have solid connection and the wires aren't touching together at all back there. It's a good idea to not have bare wire sticking out of the 485 hookups, but not too short as to not have a good connection either. I would also make sure the wire harness on the top of the camera itself isn't damaged from installation, or just loose. Confirm it's properly 'seated' in the camera, meaning, carefully take it out and put it back in and make sure it's inserted well. I see they include a spare wire harness and if all else fails I'd try the spare and see, just in case the wires were damaged or pulled during installation.
