Controlling Multiple VIRB Cameras Using ANT+ Wireless Technology
You can control multiple VIRB® cameras using one main VIRB or an ANT+® device.
When controlling multiple cameras, you must choose a main VIRB camera. This camera controls all of your other cameras, which are called extended VIRB cameras. When you start recording or take a photo on the main camera, the extended cameras start recording or take a photo at the same time.
When you use an ANT+ device to control multiple cameras, the ANT+ device controls only the main camera. The main camera passes commands received from the ANT+ device to the extended cameras.
