thanks a ton Mathew for the reply...I have one more do I connect the SDi cable to my desktop for live streaming. I currently have a PC desktop with OBS stream software I want to use for streaming our gurudwara procedings live on facebook

Hi Harjeet Singh Saini, 

To bring the SDI feed into your PC you will need one of the following solutions:

SDI to USB Adapter- An example of this product would be the Magewell XI100DUSB SDI which would allow you to use an available USB 3.0 port on your PC to connect the SDI cable using this adapter.

SDI to PCIe Card- If you are using a tower PC with an available PCIe slot you could opt for one of the SDI to PCIe options from Magewell

I have recommended the Magewell solutions above based on the stellar feedback provided by our customers who utilize their products with ours; but there are other solutions available.

Of note that you can also convert the SDI into an HDMI signal, using a converter, and then use an HDMI to USB Adapter or HDMI to PCIe Card to bring the feed into your PC.

It is worth mentioning that the more translations performed, such as SDI --> HDMI --> USB, the larger the potential impact on latency and quality of the video feed... it is best to use as few devices in the middle as possible.

I hope this helps you with your build out and if I can offer any other advice please let me know.

thanks for such a detailed response, again. If i get the SDI to USB converter, will I be able to directly input USB into my desktop and use OBS to do live streaming? Or in your knowledge, I might need something else as well. Thanks for your attention. 

Hi Harjeet Singh Saini,  

Everything listed prior should be all you need to bring an SDI camera into a production PC via an available USB 3.0 port.

If you have any other questions please don't hesitate to come back to the forums.


First time dealing with a PTZOptics Camera and I feel like I missed something along the way.

We are currently using a Cannon camera with HDMI to SDI adapter, capturing the video on a DeckLink 8K Pro capture card Capter in #4.   Mixing video using VMIX and streaming to facebook.   Working great, but the cannon can't hadle the optical zoom we need, so -- fuzzy.    Enter PTZOptics:

We added the 30X PTZOptics  SDI camera on capture in #3 and I'm getting nothing from the camera.

I'm on a 100' run of 3G-SDI cable, just like the Cannon.   Using POE for PTZ control, and I have setup the IP, and verified the (delayed) image using rtsp stream and VLC.   However, the SDI image remains black.

I swapped it onto the same cable we're using for the Cannon and it's black there also, so it possibly isn't the cable I'm using that's the problem (though I'll test that with the cannon next, to be sure.  A and B work together, C and D do not.   C and B do not work either.   Doesn't prove a thing about B or D)

Is there an incompatibility between the DeckLink 8k Pro and the PTZOptics camera?

I'm pretty sure I read multiple sites that recommended this very combination.

I haven't gotten the OSD out of the camera uet either.    Neither Chrome nor Firefox seem to be able to display the image in the web control page from the camera.

Is there a way to verify the video signal from the SDI out?    I have access to a multimeter and oscilloscope if that will help.   How can I verify this camera is not defective?

Is there a further setup to be done?

Thank you so much for your consideration.
