outgoing internet bandwidth without sacricing your direct recording quality.
Sub-stream is
oen exclusively used by apps to view live video. Users with limited internet speeds
may benet most from this seng.
Video Quality
Set the video quality as you desire. The higher video quality results in more storage space
requirement.

alarm triggered recording ends at 11:00, and if you set the post-record me as 5 seconds, it
records
ll 11:00:05.
Stream Type
Main stream and sub-stream are selectable for recording. When you select sub-stream, you
