Connect the DVR with the monitor before
startup via VGA or HDMI interface, and
manage the IPC to connect with the device
locally or remotely, the status of IPC
displays as Connect. And then connect the
device with the CVBS, and there is black
screen either.
Possible Reasons:
AfterconnectingtheIPCtotheDVR,theimage
is output via the main spot interface by default.
Steps:
1. Enabletheoutputchannel.
2. Select“Menu>Conguration>LiveView
>View”,andselectvideooutputinterfacein

Notes:
1) Theviewsettingscanonlybe

Live view stuck when video output locally.
Possible Reasons:
a) PoornetworkbetweenDVRandIPC,
andthereexistspacketlossduringthe
transmission.
b) Themotiondetectionandalarm
functionsareenabled,andthe
parametersofMainStream(Normal)
andMainStream(Event)aredierent.
So the image looks stuck due to the
imagechangesbetweendierent
resolutions.
c) Theframeratehasnotreachedthereal-
time frame rate.
Steps:
1. Verify the network between DVR and IPC
is connected.
1) Whenimageisstuck,connecttheRS-
232 ports on PC and the rear panel of
DVRwiththeRS-232cable.
2) OpentheSuperTerminal,andexecute
thecommandof“ping 192.168.0.0 –l
1472 –f” (the IP address may change
accordingtotherealcondition),and
checkifthereexistspacketloss.
Note: Simultaneously press Ctrl and C
toexitthepingcommand.
2. Check the parameters of Main Stream
(Normal)andMainStream(Event).
Select “Menu > Record > Parameters >
Record”, and set the resolution of Main
Stream (Event) the same as the one of Main
Stream(Normal).
3. Verifytheframerateisreal-timeframe
rate.
Select “Menu > Record > Parameters >
Record”,andsettheFrameratetoFullFrame.
4. Check if the fault is solved by the above
steps.
Ifitissolved,nishtheprocess.
If not, please contact the engineer to do the
further process.
