REMI: PTZ

(BETA FEATURE)

SRT Streamer PRO can accept PTZ command from Studio (with SRT Mini Server) and transfer to PTZ cams.

Studio Side

On Studio Side you need:

SRT Mini Server (ver 2.4.5+)

PTZ-controller. It could be a joystick-device or a program for example vMix or PanTiltZoom (iOS/Android). Main requirement: it should support “VISCA over IP” (TCP or UDP).

Please do special setup for SRT Mini Server: go to Settings –> Advanced Settings and type

ptz_tcp = 0.0.0.0:5678 (you can change port)

What does this mean?

This means that SRT MiniServer will pretend to be a PTZ camera.

And not just one camera but in our case four (according to the number of lines).

These fake-cameras (in reality these are Lines) will be available at the server address on ports 5678, 5679, 5680, 5681 (+1 for next).

This way we can indicate in our PTZ-controler all fake cameras by TCP-addresses:

192.168.1.33:5678

192.168.1.33:5679

192.168.1.33:5680

192.168.1.33:5681

After this the SRT MiniServer will begin to receive PTZ-commands from the PTZ-contoller and send them to the SRT Streamer PRO.

If your PTZ-controller only supports UDP (like vMix) then specify the same.

ptz_udp = 0.0.0.0:1259 (you can change port)

Then everything is the same.

Fake-camera addresses will look like:

192.168.1.33:1259

192.168.1.33:1260

192.168.1.33:1261

192.168.1.33:1262

IMPORTANT NOTE: fake-camera turn on only when a connection to the corresponding Line appears. This allows you to see on the PTZ-controller whether the camera is active or not.

Venue Side

You need

SRT Streamer PRO

PTZ-cam (one or more)

Go to Streaming setup and turn on “REMI Control” option

After connection SRT Streamer PRO will be receive PTZ-command and re-send to PTZ-cam.

So the question arises - how to link the Stream and the PTZ-cam?

It’s easy.

Just type

ptz_udp = IP_ADDRES_CAM:PORT

in Advanced options for Stream.

Thus when the streamer starts streaming this stream to the studio it will receive PTZ-commands (from SRTMiniServer) and send them to the specified camera.

Explanation

We have implemented a scheme for pass-through transmission of PTZ-commands and PTZ-responses.

Thus the PTZ-controller and PTZ-camera believe that they are working directly with each other. Accordingly all PTZ-functions that your camera supports should work without restrictions.

PTZ-devices point of view
