Cisco Cisco Video Surveillance 6620 IP Camera

Grooming—Starts when continuous recording is enabled and operates as follows:

Groom files that are marked as deleted.

Groom the oldest files on the local SD or MicroSD card when available space on the card is less 
than 1 GB.

The IP camera supports an SD or MicroSD card with a maximum storage capacity of 32 GB. For 
efficiency and performance of the local storage feature, Cisco recommends that you use a SD or 
MicroSD card with a storage capacity of 32 GB.

1 GB of the storage capacity on an SD or MicroSD card is reserved for system use and is not 
available to store recordings.

When you put an SD or MicroSD card in the IP camera for the first time, the card is formatted 
automatically if the card does not have the ext2 file system and if the directory structure that is 
required for recording is not present on the card. A card with a storage capacity of 32 GB can take 
up to 15 minutes to format.

If you move an SD or MicroSD card from one IP camera to another, the IP camera to which you 
moved the card does not format the card automatically. This feature allows you to manually recover 
any video that is stored on the card by downloading the video from the IP camera user interface. You 
must format the card before you enable recording for it in the new IP camera.

If you are not using the IP camera with Cisco VSM, set the system time and time zone from the IP 
camera user interface before you enable recording to an SD or MicroSD card. If you are using the 
IP camera with Cisco VSM, enable recording through the Cisco VSM user interface, which 
synchronizes the camera time with the NTP server. Changing the system time after recording starts 
can cause issues.

An IP camera has limited bandwidth for simultaneous reading from and writing to an SD or 
MicroSD card, which can affect the amount of data that you can copy from the card when recording 
to the card is enabled. For optimum performance of the IP camera, set the maximum bit rate for the 
recorded stream to 6 Mbps or lower. At higher bit rates, video may not be copied from the card 
before the video is groomed.

Recording MJPEG streams to an SD or MicroSD card is not recommended because the relatively 
high bit rate of these streams can affect system performance. If you do record MJPEG streams, Cisco 
recommends that you stop recording before you use the IP camera user interface to copy MJPEG 
recordings from the card.

The system allows one active download of video from an SD card or MicroSD card at a time. If VSM 
is copying data from a card (due to a user or system initiated copy operation), you cannot initiate 
another download from the IP camera user interface until the VSM download completes. Similarly, 
if you are using the IP camera user interface to download video from a SD or MicroSD card, video 
cannot be downloaded from VSM until this download completes.
