Recording and Bandwidth
The Recording and Bandwidth settings define how long recorded video is stored. You can set the maximum
record time for each camera connected to a server, and configure Data Aging settings.
Video Retention
The Total Record Time is estimated based on continuous recording and may not reflect the actual video
retention.
The actual video retention is determined by the Max. Record Time setting and the average camera data
rate. The actual retention time may exceed the Max. Record Time setting by 5 minutes.
Data Aging
By default, the Data Aging setting stores both high-resolution and low-resolution video until the Tier 1
storage is full. Once the storage is full, older video will be deleted.
To increase the amount of video stored when the Tier 1 storage is full, update the Data Aging setting to
discard a percent of the high-resolution video. The system will discard the oldest high-resolution video and
only store the low-resolution video to maximize storage. The oldest video stored will be low-resolution.
The extent of data aging that is available depends on the cameras connected.
l For JPEG2000 or JPEG compression cameras, data aging is available at three rates:
l High Bandwidth — Records at original quality.
l Half Image Rate — Records half of the data to make room for new recordings.
l Quarter Image Rate — Records a quarter of the original data, allowing you to still view older
video.
l H.265 and H.264 cameras that support data aging, are available at two rates:
l High Bandwidth — Keep the original high quality video and a secondary low resolution
stream.
l Low Bandwidth — Only keep the secondary stream of low resolution video.
Note: Data aging only occurs when the secondary stream is enabled.
l For H.265 and H.264 cameras that do not support data aging, only the High Bandwidth video is kept.
