I'm trying to figure out what I need to setup a tally system in our studio so that the talent knows which camera is live. We have 3 JVC GY-DV500 cameras and a Panasonic AGMZ70 switcher. The switcher has a port for tally but it looks like the Cameras do not so I will have to rig something up myself.
Any idea what I will need to make the system? I was thinking I would use some LEDs, but do I need a power supply for them or does the switcher supply the power?
