Configuring the MVG 400 114

CAUTION: When you update a recorder's disk allocation or size settings, all the

recorded video that is currently stored on the hard drive is deleted.

Video storage normally follows the FIFO (first-in, first out) model: when the disk space

allocated to a recorder is full, the system automatically erases the earliest recordings from the

camera to make space available for new recordings. If this is not desirable, linear recording

can be implemented instead. In this case, recording ceases for the camera when the disk space

allocated to it is full. Recording from the camera can only be started again after the existing

recordings are manually erased (see Erasing Recorded Video, page 156).

To set advanced recorder settings for a camera:

1. In the bottom of the Camera configuration screen, under Recorder, select Enable

Advanced Settings. The fields required to configure advanced settings are displayed

along with the other recorder settings above the checkbox:

2. To modify the disk allocation for this recording stream, under Size on Disk, specify the

proportion of the disk space to allocate for the stream, as a percent value.

The percentage that is already allocated for the other cameras is indicated above the field

– for example, “33% in use by other recorders.” You can choose to allocate as much of

the remaining disk space to this recorder as you wish. For example, if 33% of the total

available disk space is already allocated to the other recorders, you could choose to

allocate an additional 60% to this recorder. This would mean that 93% of the disk space

is allocated to all the recorders together. The sum of the Size on Disk values of all the

recorders cannot exceed

98.

Note: To modify the allocation of the other recorders, navigate to the

Camera

configuration screen of each recorder and modify the value in the Size on Disk field

there.

Note: To reset all disk allocations to their default values, in the

Camera Summary

screen, click Set Recording Disk Size to Default.

3. To modify the video quality settings, adjust the values in the following fields as

necessary:
