Q.
I push the record button, but the DVR does not start recording, why?
A.
Push the display button to see if there is a hard disk detected, also if the DVR is in schedule
mode (there is a “S” on the screen in yellow), you cannot start recording by pushing the
record button, you have to push the schedule button again and enter your password to cancel
schedule mode.
Q. I push the stop button, but the DVR does not stop recording, why?
A.
If the DVR is recording in schedule mode (there is a “S” on screen), you cannot stop
recording unless you quit schedule mode first. Push schedule button and enter your password
to cancel schedule mode.
Q.
There is movement on the screen, but the DVR does not start recording.
A.
Make sure the motion detection of that channel is on, the area set is ok, the A/M rec time is
not set to off, that time of schedule is set to “A”, and the DVR is in schedule mode. You can set
the motion level to a higher setting such as HIGH or VERY HIGH if all other settings are ok.
Q.
When the network connection between DVR and client computer is cut off, why does
the DVR halt and the clock stop?
A.
If the network is cut off abnormally, the DVR4Net will halt for 20 seconds without response
to any front panel buttons while it resets. After 20 seconds, it will restore to normal state, but
the icon that shows network status won't disappear until the network reset after10 minutes.
In this period the client computer cannot connect to the DVR and you can’t enter the
network menu.
