Abstract: Systems, devices, and methods for synchronizing the operation of a first shutter of a first camera with the operation of a second shutter of a second camera without a physical tether between the first and second cameras. The method includes: receiving a global positioning system (GPS) pulse-per-second (PPS) signal at the first and second cameras; and in response to a unique timing pulse in the PPS signal, simultaneously actuating the first and second shutters.
