Record: Switch on/off recording function for every camera. DVR records
the camera only if the camera’s option is checked here. Then you can use
manual, schedule, motion detection and sensor alarm recording options for
the camera.
Resolution: DVR supports CIF and D1. D1 option is not currently
available.
Alarm record hold time(S): Set the length of time DVR records after alarm
finishes. It has 4 options, 30, 60, 120 and 180 seconds.
Recycle: Enable HDD recycle. If checked hard drive will overwrite older
files once it is full. If unchecked it will stop recording when HDD is full.
Note: Video quality, frame rate and resolution are closely related to used storage space.
The higher the value is, the higher the bit rate and more space recordings take up on the hard
drive.
