Dan, I used a 3 way HDMI Switcher connected to one of my Intensity Pro cards and connected remaining Camera directly to the other Card. I also use HDSDI HDMI Mini Converters for longer runs with a 4 way HDSDI Switcher. I record using On-Air 2 so I can switch and monitor the other Camera’s before I change over in On -Air 2
