In here, the resolution means required horizontal and vertical pixels in a page. The resolution is indicated as (horizontal) X
(vertical) pixel number. Select one setting from 352×240/288, 720×240/288, and 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 shows DVD level picture quality. When the picture quality gets higher, the storage capacity is bigger and
the recording period will be shorter. Thus, selecting an appropriate resolution according to the situation is important.
<IPS and Quality Setup>
Select the IPS (Images Per Second) for each camera channel.
IPS means, “Images per second”. The system automatically calculates “Remaining IPS” that users can use.
The setting value of “Quality” directly influences the byte size per image. For example, the byte size decreases as the quality
goes lower. At low quality settings, blocking (mosaic) phenomena tends to appear, which is in result of high compression. In
contrast, blocking phenomena disappears as quality goes higher. As quality increases, the required storage space per image
increases, which leads to the shortening of total available recording period. Therefore, consider the necessary recording
period, the importance of each camera image, and the quality of the analog signal when setting the recording quality.
The maximum number of IPS is 480(400)IPS for the system. If the recording setting exceeds the limit
while users setup the Resolution and IPS, the popup message “Please Check IPS setting.” will show up.
Please refer to the remaining IPS and setup the resolution and IPS again.
