HD is selected as the video compression setting for stream 1, users may only be left
with M-JPEG or VGA for stream 2. This is a camera limitation.
3. Please refer to our camera compatibility list for supported camera models.
4. More bandwidth is required for Smart Recording. Please estimate your bandwidth usage
before using this feature. Take Vivotek IP8132 for example, this model offers three
streams. Stream 1 uses 663K bps, Stream 2 uses 1000K bps and Stream 3 uses 3000K
bps (Please refer to Vivotek Video Transmission Calculator for detail.) The total
bandwidth required is 4663K bps (663K + 1000K + 3000K). If 30 Vivotek IP8132
cameras are connected to a NVR for live view and Smart Recording is used, at least
133930K bps bandwidth is required.
6.6.2.4 Edge Recording
When Edge Recording is enabled on VioStor NVR, the camera can save the recording
files on its local storage (such as a SD card) even when the connection to the NVR suddenly
becomes unavailable. After the connection is resumed, the NVR will check its recording files
and compare the recording schedule set by users. If the NVR detects that recording files are
missing, it will request the camera to upload the missing part.
