Upgraded TO1 4K Projector with Electric Focus: Adjust Screen Focus with a Remote!
With the upgraded TO1 outdoor video projector, you can simply use a
remote to adjust the projector's focus. This will be a boon for those
video projectors which are ceiling mounted or placed not easily
accessible. You'll be free from space constraints and no longer need to
walk to the projector or stand on a ladder to manually adjust the
projector's focus.
