Appendix 2 Operation Notes
Audio input must use active audio sensor. Keep audio sensor away from audio power
amplifier.
When the DVR is in the menu operation mode, remote user can’t modify the parameters
through the network.
Set motion detection sensitivity at 50-80 to effectively detect moving objects.
Following parameters won’t be active unless system reboots after save:
auto-recording
when
power on, network parameter setup, VGA resolution.
Never attempt to format the hard disk when DVR is recording.
If the buzzer beeps when DVR is in startup, maybe no hard disk is connected or some
video input
channel is not connected. Please check these situations.
If no hard disk is connected successfully, no operation related to data storage on hard disk
is
allowed.
If unformatted hard disk is connected, user should enter into main menu to format this disk.
When the hard disk is full, and “
recording auto overwrite
” function is not active, the message
“
Hard disk full, recording with overwrite?
” will be displayed. Press “
OK
” to
start overwrite or
press “
Cancel
” to stop recording.
When the video signal from one channel is lost, the interface for this channel will prompt
‘
No
signal
’.
When channels from 1 to 4 are displayed in a 4 partition screen, channels from 5 to 8 and
onwards can also be switched by successive pressing of the 4 partition key.
Never change the date or time during recording as it will cause file corruption.
