Video between tracking rooms.

First thing that came to my mind was some multi camera home security system which has an app.

Cheap camera like this:

MOKOSE 12MP HDMI Camera 1080P USB HD Streaming Webcam, Recording 4K@30FPS Industry C/CS-Mount Camera with 3.2mm No Distortion Manual Lens a.co/d/dDjNqN9

And a cheap TV. HDMI between rooms. It's real time, so no latency.

I ordered the suggested camera.

There are CAT-6 cables in the walls between the rooms.

Is there a way to use the CAT-6 cables as HDMI from the camera to the monitor?

The problem is you need send and returns in each room for camera and TV’s. And then a way to mix multiple inputs so you can see all the other rooms at the same time like a zoom meeting. Unfortunately zoom and other computerized and Wi-Fi stuff has latency. Also you probably need a cat6 wire for each room send and return, along with HDMI splitters and extender transmitters and receivers. I don’t know what your budget is, but it can go into many thousands pretty quick if you are serious about quality, zero latency, and running long runs between each room. If that’s ok, then it can be done.

Ways to lower cost might be skipping the Ethernet stuff and putting screens and cameras 40 feet or less between all of them, and run HDMI wire directly through the walls so that it’s not far of a journey. Will take some serious thought if it’s even possible. You’ll still need HDMI splitters in each room to send the camera info to the other rooms, and HDMI cable in the wall for each. For viewing each room you can either plug into the TV HDMI ports, HDMI 1, HDMI 2 etc. but then you have to change the input and only see one room at a time unless you have a security type mode that shows multiple inputs at once. Since that mode shrinks screen space anyway, you might want to just get cheaper/smaller screens and get one for each signal being received. .. ie, if each room you want to see 2 rooms, use 2 TVs in each room. Staying Latency free and cheap is not easy these days. You might be able to find some old used hard wired (SDI) video equipment or security gear that you can run wire through walls and get it all working for super cheap?
I hope this helps you brainstorm your solution



Edit: another thing to consider, a lot of cheap TVs are using digital chips and firmware, I don’t know what kind of latency that might add if any. So you may want to start one tv/camera at a time and test for latency

Well I bought Svart's recommended camera and HDMI to CAT6 converters
Seeing I only need one camera from the analog control room to the tracking room and already have all the Cat6 lines in all the walls.

If all goes well, I just get another converter to go from the Daw control room to the tracking room and use the same camera. It's a cheap enough setup.
Both control rooms don't use the tracking room at the same time.

I 'm going to hook it up and give it a try.
Happy 4th
