Save Storage by Setting Event Recording Frame Rate
Video surveillance system is aimed to preserve as much evidence as possible, and you may
want a view to be recorded 24/7 to capture every important moment; however, the general
recording methods provided by most network recording systems- event and schedule
recording, will either consume too much storage or have risk in missing important scenes. The
“ Set Frame Rate for Event Recording Mode ” function makes NVR system record everything
at economical storage usage by automatically adjusting video frame rate during event
recording period.
Schedule Recording
Continuous recording promises no loss of video evidence; however, large data storage is
required because this video is always recorded at the high frame rate you set for device.
Event Recording
This mode is storage-efficient because recording would stop during the non-event moments,
yet certain vital video evidences may be missed if the trigger device fails to take effect.
