Track and record human figures between 1.6 and 16.4' away with the black Smart Tracking Phone Holder from YONGNUO. With the ability to support devices up to 2.2 pounds, this mount moves your phone to keep subjects in frame while minimizing pauses, shaking, and more. The integrated lithium-ion battery lasts for up to 22 hours and can be recharged via the mount's USB Type-C port using the included cable. The bracket part of this device can be removed from the main body and used alongside other accessories that have a male 1/4'-20 screw. Or, once the bracket is removed, other compatible devices may be attached. Thanks to LED indicators, you'll be able to tell when the camera is operating, needs to be charged, or is charging.
