THETA basically uses a smartphone app to set the camera settings and shoot via smartphone or the camera’s shutter button. By activating Remote Control plug-in, you can use a commercially available Bluetooth® remote control to shoot from a distance.
The Remote Control plug-in is pre-installed and can be used by updating the THETA to the latest firmware.
