I have been looking for the same thing. I don’t have any answer for me, but I will share some of my thoughts. I have sony nx5u cameras.
What I created last year and have been using is an nx5u mounted on a pan tilt mechanism. The pan tilt mechanism is mounted on a dj speaker type tripod.
Then I have a cable consisting of cat 6 for control and RG59 coax for the sdi. I multiplexed the Lanc connection through some of the unused cat 6 wires.
I created a control board and mounted it on an unused tripod which I put in the back of the church. I route the 100 foot wire on the floor.
I mounted an Ikan sdi monitor on it. I mounted lanc controller on it. I mounted controls for the Pan tilt head on it.
So, I sit in the back and can do a pan tilt, zoom, auto focus, manual focus etc.
It works quite nicely. However, I was looking for making more of them, or smaller, so that it is not so obvious.
What I discovered is that sony just came out with a new model line of ptz cameras, SRG 300
Here’s a link to the product brochure: https://pro.sony.com/bbsc/assetDownloadController/SRG%20Brochure_final.pdf?path=Asset%20Hierarchy$Professional$sel-47425SEL-asset-407970.pdf&id=StepID$SEL-asset-407970$original&dimension=original
You can control it using the sony controller device. Or, there is a company that has made tablet pc software to control it.
You can use a atomos ninja to monitor and record if you want.
At this point, the ptz plus external recorder is the same price as another nx5u, so I started thinking it is not worth changing.
