•
Resolution: Image resolution is a measure of how much detail a digital image can hold: the greater the
resolution, the greater the level of detail. Resolution can be specified as the number of pixel-columns
(width) by the number of pixel-rows (height), e.g.,1024×768.
•
Bitrate: The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the number of
bits/time unit and not distance/time unit.
•
Enable H.264+ Mode: H.264+ mode helps to ensure high video quality with a lowered bitrate. It can
effectively reduce the need for bandwith and HDD storage space.
A higher resolution, frame rate, and bitrate setting will provide better video quality, but will also require
more internet bandwidth and use more storage space on the hard disk drive.

7.3.2 Sub-Stream

The sub-stream is a second codec that runs alongside the mainstream. It allows you to reduce the
outgoing internet bandwidth without sacrificing direct recording quality.
The sub-stream is often exclusively used by smartphone applications to view live video. Users with limited
internet speeds may benefit most from this setting.

7.3.3 Picture

The picture refers to the live picture capture in continuous or event recording type.
•
Picture Quality: Set the picture quality to low, medium, or high. Higher picture quality results in more
storage space requirement.
•
Interval: The interval of capturing live picture.

7.3.4 ANR

ANR (Automatic Network Replenishment) enables the IP camera to save the recording files in local storage
when the network is disconnected; when the network resumes, it uploads the files to the device.
Enable ANR (Automatic Network Replenishment) via a Web browser (Configuration > Storage > Schedule
Settings > Advanced).

7.3.5 Configure Advanced Recording Settings

1. Go to Storage > Schedule Settings > Record Schedule/Capture Schedule.
2. Check the Enable checkbox to enable scheduled recording.
3. Click Advanced to set the recording parameters.
