Enable time shift caching stream: Select one stream as the time shift cache stream. This function
enables the time shift cache stream from the Network Camera, which will store video in the camera’s
embedded memory for a period of time depending on the cache memory size on 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 users to
retrieve video footages taken before the occurence of an event.
This Network Camera supports multiple streams with frame size ranging from 176 x 144 to 1920 x 1080.
The denition of multiple streams:
■ Stream 1: Users can dene the "Region of Interest" (viewing region) and the "Output Frame Rate" (size
of the live view window).
■ Stream 2: Users can dene the "Region of Interest" (viewing region) and the "Output Frame Rate" (size
of the live view window).
■ Stream 3: Users can dene the "Region of Interest" (viewing region) and the "Output Frame Rate" (size
of the live view window).
■ Stream 4 (Global view stream): This stream captures the full view of the video and users can also
dene the "Output Frame Rate" (size of the live view window).
Click Viewing Window to open the viewing region settings page. On this page, you can set the Region
of Interest and the Output Frame Size for streams 1 ~ 3.
Please follow the steps below to set up those settings for an individual stream:
1. Select a stream to congure its viewing region.
2. Select a Region of Interest from the drop-down list. The oating frame, the same as the one in the
Gloabl View window on the home page, will resize accordingly. If you want to set up a customized
viewing region, you can also resize and re-position the oating frame to a desired position with your
mouse.
3. Choose a proper Output Frame Size from the drop-down list according to the size of monitored
device.
