RECORD SETUP

 Settings Tab)
 Recycle When Disk Full: Selecting this box records over
the oldest video data once all available storage space has
been used. When the box is not checked, the DVR stops
recording once all available storage has been used.
 De-Interlace: Selecting the box toggles between On and
Off. (16-ch model only) When set to On, the DVR will turn
the de-interlace filter on while recording video with Very
High (D1) resolution.
NOTE: The video signal has a time difference of 1/60 second (1/50 second for PAL) between odd and even
fields because it is composed of 60 interlaced fields per second (50 fields for PAL). When recording video
with Very High (D1) resolution, video is made up of frame units combining two fields – one odd field and one
even field. This can cause horizontal scan lines or flashes in areas with motion because of the time difference
between the two fields. Turning on the de-interlace filter provides clearer video by eliminating these horizontal
scan lines and flashes.
 Record Audio: Selecting the box records audio from up to eight inputs when video is recording.
 Auto Deletion: Adjust the length of time recorded data will be kept by using the slide bar or Up and Down arrows
buttons. Selecting Never will disable the Auto Deletion function. The DVR automatically deletes video recorded
earlier than the user-defined period under three conditions: at midnight, whenever the system reboots or whenever
the user changes the Auto Deletion settings.
NOTE: The following description is for 4- and 8-ch models only.
 Resolution: Selecting this box records over the oldest video
data once all available storage space has been used. (4- and
8-ch models only) When the box is not checked, the DVR
stops recording once all available storage has been used.
NOTE: The total ips of all camera channels will be limited
to 120 ips (60 ips for 4-ch Model) when set to High
resolution and 60 ips (30 ips for 4-ch Model) when set to
Very High resolution.
NOTE: When set to High or Very High resolution, the maximum recording speed of each camera channel might
decrease so as not to exceed the total ips of all camera channels. The 8-channel DVR has two camera groups
(No. 1: cameras 1 to 4 and No. 2: cameras 5 to 8), and setting resolution will be applied to all the cameras within
the same camera group. See the table below.
