This is the new Synco CE3 Wireless tally system for vMix. It will work with Atem switchers and other devices but works really well directly with vMix as a stand alone production system. For $300 for 4 lights, the transmitter, 4 batteries and 2 chargers, it is a great system. Very simple set up and no triggers or Activators to set up! Expandable up to 32 transmitters in one system, with 10 hour battery life and a 1000 foot range, makes this a perfect addition to your vMix production set up.
