Have more than one racecar? It's hard to drive move than one of them at a time, but a real hassle to try and move cameras and antennas from one car to another to support your livestream.
The Sentinel prewire kit includes :
LTE Antenna 2 Cameras 2 HDMI Cables
Once installed, you are free to simply unplug your Sentinel Video Unit and move it between wired cars!
