Live Feed setup question, multiple cameras, mixer, wireless wifi connection

[haring]

I am looking into building a live feed system. I would like to provide live feed for online events, weddings, workshops.

I would like to have 2-3 cameras to record the event. I am thinking
about attaching a wireless transmitter to the cameras to send the signal
to a live feed video mixer. I would like to switch back and forth
between cameras signal is broadcasted to the online viewers.

How would you do this? What king of DSLR/mirrorless HDMI transmitter you
would use from the camera to the video mixer. What kind of solutions
there are to switch back and forth between cameras? Thanks so much!

Cameras of your choice - maybe the Blackmagic Micro Cinema
Hollyland wireless HDMI sets - just a matter of what fits your budget
Blackmagic Design Atem Mini (Pro ISO model adds recording)
LiveU transmitter

The more you can power centrally the better off you'll be.  That and a sizable GoalZero battery setup since there is no such thing as enough battery power on hand.

Does the Hollyland Mars 300 PRO working with Canon Webcam Utility? I would like to send signal without capture card via Canon's Webcam Utility to the computer...

No, it will not work.  The HollyLand is a HDMI setup, the Canon Webcam Utility is a USB data streaming.  The Hollyland Mars 300 Pro has a USB connection for powering from usb batteries.

The Canon webcam utility is not designed for this use.  It will not let you switch between cameras & I'm not sure it'll let you record in camera at the same time as you are using via USB.

There are 2 different paths you can take, using HDMI as your camera/switcher platform, or using software.  Here's a multi-cam setup using HDMI:

If you want to do it all in software, take a look at OBS & Streamlabs:

You can take any HDMI source & capture it with the right device, and it's not expensive in the larger scope. It's just a matter of how do you want to handle switching & streaming.

There is no right solution, just what solution are you most technically proficient in.  You can't be everywhere at once, so what are you best handling and how can you optimize for your crew?
