RECORD

4.4
4.4.1. CAMERA
Adjust the recording settings for each channel separately from the menu shown below.

ON/OFF
This switches "recording" on and off in each channel. If recording is not required on the selected channels,
even when the camera signal is input, set the recording of the corresponding channel as [OFF]. Recording
of the channel stops without disconnecting the camera's BNC cable.
RESOLUTION
Select the desired resolution for each channel. Users can select eithjer 352×240/288, 720×240/288,
720×480/576 or 960x480/576. As the resolution number increases, the picture quality becomes better. For
example, 352×240 is VHS level and when high quality camera is used, 960×480/576 shows DVD level
picture quality. When the picture quality gets higher, the recording file size becomes bigger and the
recording period will be shorter. Thus, selecting appropriate resolution according to the situation is
important.
FPS
The system automatically calculates frames per second (FPS) and displays it as "Remaining FPS".
Note
1) VBR (Variable Bit Rate)
Focuses on the image quality rather than data size. So, in case of complicated & high frequency
motion image, data size is larger and the recording period is shorter.
In this mode, the user can change each camera's quality by selecting one of the following
options: Low / Standard / High / Highest.
2) CBR (Constant Bit Rate)
It focuses on keeping constant data size regardless of the image quality. It can be helpful for
maintaining recorded data as requested period but, in case of complicated & high frequency
motion image, the image quality is getting worse accordingly.
In this mode, the user can change each camera's quality by selecting one of the following
options: 128K~896KBPS / 1M~3MBPS / Low / Standard / High / Highest.
