Please note: Scheduled Recording and Alarm Recording must be enabled first.

Limitations and Restrictions:

1. A camera stream can only be selected as for either Regular Recording or Alarm

Recording.

2. The number of streams supported and stream properties (such as codec,

resolution, frame rate and quality) vary based on camera models, and the same

property value may not be available as other properties are changed. For

example: if H.264 or Full 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. Because 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 663Kbps, Stream 2 uses 1000K

bps and Stream 3 uses 3000Kbps (Please refer to Vivotek Video Transmission

Calculator for detail.) The total bandwidth required is 4663Kbps (663K + 1000K +

3000K). If 30 Vivotek IP8132 cameras are connected to a NVR for live view and

Smart Recording is used, at least 133930Kbps bandwidth is required.
