[Record Frame Rate Control]
Set the recording frame rate to meet your storage
requirements.
„
Maximum recording frame rate:
This option is available when the recording codec of
the IP camera is set to JEPG. Select the frame rate from 1 to 30 fps.
„
Record key frame only:
This option is available when the recording codec of the IP
camera is set to MPEG4 or H.264. You can choose to record key frames instead of all
frames. This option is related to the GOP setting of the IP camera. For example, if the
GOP value is set to 30, there is only one key frame among 30 frames. For the GOP
setting, see
4.1.2 Video Settings
