Vivotek IP816A-LPC-v2 Installation Manual page 17

Operation Procedure:
1. Press the Snapshot Recording button, e.g.,
when a car is passing the field of view. A short,
2.5 seconds of video recording will be available
(including 1 second of pre-recording and
another second of post-recording).
2. The recording takes place on Stream 1 with a
focusing result calculated from the full of the
current field of view.
3. The Snapshot Focus comes with an embedded
Quick time player. Users can review the
current focusing results on a viewing window.
Users can also use the left arrow key on
their keyboard to go through the recording in
a frame-by-frame manner (after the video is
played once).
In this way, an installer can immediately
examine whether the focus is optimal when
a fast going car is captured by video. If not,
he can tune the focus again and review the
imaging result until satisfied.
4. Users can also download the short recording
clip to a PC. Note that if the Snapshot Focus
page is refreshed or the web session is closed,
the recording will be erased.
Note that you can use the arrow buttons on the
sides of the Focus tuning bar to find the best
focus.
