3.3 Record
3.3.1. Camera
ON/OFF
It is to switch “recording” on and off in each channel. If recording is not required on the selected
channels, even when the camera signal is inputted, set the recording of the corresponding
channel as [OFF]. Then, recording of the channel stops without pulling camera BNC cable off.
[ON] or [OFF] can be selected. The default is [ON].
FPS
It means “Frame” consisting even and odd fields per second. The system automatically
calculates “Remained FPS”.
RESOLUTION
It means required horizontal and vertical pixel number of a page. The resolution is indicated as
(horizontal) X (vertical) pixel number. Thus, select one setting from 352×240/288, 720×240/288,
720×480/576. Default is 352×240/288. As the resolution number increases, the picture quality is
higher. In fact, 352×240 is VHS level and when high quality camera is used, 720×480/576 show
DVD level picture quality. When the picture quality gets higher, the storage capacity is bigger and
the recording period will be shorter. Thus, selecting appropriate resolution according to the
situation is important.
QUALITY
The setting value of “Quality” directly influences the byte size per image. For example, the byte
size decreases as quality goes lower. In this case, blocking (mosaic) phenomena tends to appear,
which is resulted by high compression. In contrast, blocking phenomena disappears as quality
goes higher. In this case, the required storage space per image increases, which leads to
shortening of total recording period. Therefore, give consideration to the necessary recording
period, importance of each camera image, and quality of analog signal when setting the
recording quality.
AUTO DEL (Auto Delete)
It means that the system will delete video whatever is recorded longer than the number of days
set by “Auto Del” in accordance with privacy regulation in certain country.
