Welcome to the PTZOptics forum(s)!

This thread has been created for end users to discuss the topic of the SDI output when getting started with the PTZOptics cameras.

Please make sure to respect the experience level(s) of all users at all times when posting within our forums or your account may have access removed.

Currently the PTZOptics cameras only supply FULL FRAME rates via any output... including the SDI.

Currently audio DOES NOT embed via the SDI output.

This features is only available via the IP, USB and HDMI outputs

Note that you must change the Setting in the cameras OSD from DVI to HDMI for audio to travel via that output if it is not currently doing so.

There is no method of control available via the SDI connection.

Looking to purchase a PTZ Optics camera for our church. Like the remote functions. I will need to route cabling over a 40 to 50 foot span to a room off of our sanctuary. We will be doing an external mix of the audio using a Behringer X-32 Compact digital mixer. How should I route audio for live streaming? the camera model is the PT20X-SDI-WH-G2 (White).


Hi Doug,

This all depends if you are going to be pulling the camera feed into a computer and streaming out from there using a program such as Vmix or OBS, or are you planning on streaming directly form the camera?

If you stream directly from the camera to a Youtube of Facebook live, you would need to sum the audio down to a 3.5mm connection and bring it in to the line in on the back of the camera to be embedded in the network feed. This would have to be a live level signal, so most of the outputs of your board should work. 

If you want to bring the audio back to you computer and use one of those programs to put everything together, you could sum it down to bring it in via the 3.5mm connection on the computer, or use a basic Audio interface to bring the audio into the computer. It does look like your Behringer has a USB connection to the computer, but I am unsure of if you can bring that in as a source in a Video program such as Vmix or OBS just because I have not had the chance to test with that board myself. 

If you want to talk any of this out please feel free to give us a call, 610 518 2200. 

Hi guys, 

First time poster and to be honest trying to make my way through this new world of ptz stuff.  I did a search and could not find an answer for my question.  So if this info is already covered please point me in the right direction.

My question deals with the use of SDI and USB.  I thought I saw a how to video from you guys (I cant find it now)  where the Camera (PT20x-ndi) which is connected to my tricaster 460 AE through SDI.  Can I use the USB port to connect to my TC for PTZ control?  I thought I saw that I could on a video.  If not what the best way to give me PTZ control while not using NDI.  Also the camera is about 12 feet away from the Tricaster.

Thanks guys


Hi Jerald,

Thanks for joining our forums and welcome!

So we did have two (2) videos a few years ago documenting a method to use a USB-->RS232 adapter to add PTZ control to your Tricaster.

Over time the videos had less value as the feature became increasingly unreliable and the content was removed to not mislead people on this capability.

With the fading of the hardwired RS232 support NewTek did add, to systems running Advanced Edition 2, the ability to gain PTZ control over the network and NDI is not required.

If your system is currently running this edition you can navigate to the control section for the camera(s) connected and simply type the IP address and port (5678 - TCP or 1259 - UDP) of the camera to gain reliable PTZ control.

I hope that this information is helpful in guiding you towards a solution for use with your Tricaster and PTZOptics cameras.

If you have any additional questions, ideas or concerns related to this information please let us know and we'll be happy to continue to assist to the best of our abilities.

I hope this message finds you having a wonderful day.

gotcha....i forgot about the PTZ setting on each input.  Awesome thank you

Hi Jerald,

I remember the first time someone told me it was there... I was amazed I had never discovered it before :-)

If there is anything else we can help with please don;t hesitate to come back.
