Approach Tech NVR-2018 manual Configuring Recording Settings, X Audio OFF

4. BASIC OPERATIONS

This section shows you how to operate and manage the NVR when it gets in the way.

4.1 Configuring Recording Settings

Recording Time settings (Image Resolution and Image Quality Setting)

Recording time will vary depending on the image size, quality, and the capacity of the hard-disk drives. Generally, the NVR comes with a built-in hard-disk drive for continuous recording under most recording conditions. The table below shows the possible recording times based on a 20GB hard-disk drive at certain refresh rates and the corresponding image quality. With one or more hard-disk drive(s) in operation, please calculate the recording time using the table below in accordance with your requirement. For example, if the unit is set to record images with HIGHEST quality at a 352 X 240 resolution, and normally a 20GB hard-disk drive will be filled in 13 hours (See the gray area in the table). If the total capacity of 80GB hard-disk drives is in use under the same refresh rate, image resolution and image quality, it will be filled in 52 hours (4 times the rate of a 20GB hard-disk drive).
