must disconnect and reconnect the power cord of the Network Camera in order for the new setting to
take effect.

Advanced Mode
: Check this item to enable the time shift cache
stream on the Network Camera, which will store video in the camera’s embedded memory for a period of
time depending on the cache memory of each Network Camera. This function can work seamlessly with
VIVOTEK’s ST7501 recording software. When an event occurs, the recording software can request time
shift cache stream from the camera, which allows the user to get an earlier video recorded before the
occurence of an important event.
Video orientation: Flip--vertically reect the display of the live video; Mirror--horizontally reect the display
of the live video. Select both options if the Network Camera is installed upside-down (ex. on the ceiling)
