Enable time shift caching stream Advanced Mode : Check this item to enable the time shift cache
stream on the video server, which will stores video in the video server's embedded memory for a period
of time depending on the cache memory size of each video server. 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 retrieve pre-event video data.
