[ANSWERED] PTZ Cam and Isadora

liminal_andy

@gertjanb Makes sense. The dream in my mind (in general, not for your specific use) is to get Isadora transmitting VISCA-IP out to LAN (and thus StreamWeaver), then having remote StreamWeaver on a different LAN locally rebroadcast the VISCA-IP commands to local cameras, giving remote operators the PTZ control in a fully decentralized workflow. The result could be non-linear using whatever inputs the Izzy patch is using, or fully serialized from the single Izzy cue list. I will need to learn more about how Isadora would need to be configured for that use, as the main issue I'm having is with the various controllers and the unique ways they interface with LAN.

@gertjanb Can't tell a lot about PTZ cam. My previous experience was years ago with Canon VC-C50 and VC-C4 and I am now about to use for a show a Marshall CV610-U3W-V2 , wich I choose mainly because it was the cheapest I found ( 1200€) with the features I needed , like a 10x zoom. It can be control in Pelco P or D, and Visca thru a USB link direct to the computer that also transport the video. But I was not able to detect the port in Isadora even with the driver they provide, and the video has a slight delay that I can't bear. I was anyway planing to use serial port adaptater, paired with a joystick, to use both Isadora and manual control.

About stability, I can be wrong but I have the feeling that this king of surveillance camera in this range of price ( above a 1000 €/$ ) are made to be strong and reliable, and I don't see what kind of bug can happen... But I may be change my opinion within 2 weeks of intensive rehersal and will come back to tell you!

Dear All,

Because I want Isadora to be a strong player when it comes to remote performance, this is something I am interested to support with new modules, comm protocols, etc.

From what I've ready above, VISCA seems to be a widely used standard -- though I can see how a serial connection as @GertjanB mentioned would be in many ways easier and just as powerful.

But what cameras, realistically, will people out there be using for this? The Sony cameras are pretty pricey, though maybe that's the way to go because the image quality would seem to be very good.

In any case, I am following this thread with great interest. Let's see if we can zero in on a means to support this kind of performance.

@GertjanB -- since you have a pending project, I invite you to write me personally about this. Maybe we need to have a video-call to talk it over.

Best Wishes,
Mark

So the least expensive VISCA capable PTZ camera. It seems that the company PTZOptics is a kind of go to, and is used for broadcast applications, but even the cheapest model (US$1599) is still quite expensive for lower-budget shows.

When I search B&H for VISCA, the cheapest entry -- AViPAS AV-1080 3G-SDI -- comes in at US$650.

I see various security web cams for as little as US40, but none of them use VISCA and generally they use a non-open protocol that isn't even published in the manual. So I would rule those out.

Am I missing something? Are there less expensive PTZ cameras out there that our users could use? I'm ready to commit to getting a VISCA capable camera so that we can add VISCA control to Isadora. But I'd love some input from anyone who knows more than me.

Best Wishes,
Mark

I also found the Logitech PTZ camera. (±900€) But I haven looked into depth into it to see if it is controllable. (I'm currently working on two other projects)

@mark We are now writing the dossier and looking for money for the project. When we found the money and I have one I'll let you know. If all goes well we start in December.

Hi,

PTZ cameras are one device option to look at. I am thinking perhaps the proliferation of gimbals is another - somewhat related device - that can be considered for Izzy plugin development. I have a DJI Ronin M and a Ronin S gimbal and just a quick comparison of cost suggest these possibly provide good value and flexibility compared to the PTZ camera lineup - admittedly they are a BYO camera option. The PTZ cameras appears to have some shared protocol, but the diversity of gimbal makes and models are likely all proprietary. Still I would definitely use an Isadora Plugin that implemented gimbal control as an alternative to acquiring a PTZ camera. Specifically because the gimbal allows any number of camera types to be mounted and offer comparable functionality to PTZ.

Just a thought.

Best wishes

@mark „Are there less expensive PTZ cameras out there that our users could use?“

Wanted to know about this in 2025

I've been working with the OBSBOT camera's for a while now they have different models in different price ranges and they work great. I like the tail models because they are completely wireless.

you can control them using OSC but i use the AI tracking mode most of the time.
