shows as Connected; and then you connect the HDVR with the monitor via VGA or HDMI interface and
reboot the device, there is black screen with the mouse cursor.
Connect the HDVR 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 Connected. And then connect
the device with the CVBS, and there is black screen either.
Possible Reasons:
After connecting the IPC to the HDVR, the image is output via the main spot interface by default.
Steps:
1. Enable the output channel.
2. Select “Menu > Configuration > Live View > View”, and select video output interface in the drop-down
list and configure the window you want to view.
Notes:
1) The view settings can only be configured by the local operation of HDVR.
2) Different camera orders and window-division modes can be set for different output interfaces separately,
and digits like “D1”and “D2” stands for the channel number, and “X” means the selected window has no
image output.
3. Check if the fault is solved by the above steps.
If it is solved, finish the process.
If not, please contact the engineer from our company to do the further process.
 Live view stuck when video outputs locally.
Possible Reasons:
a) Poor network between device and IPC, and there exists packet loss during the transmission.
b) The frame rate has not reached the real-time frame rate.
Steps:
1. Check the parameters of Main Stream (Continuous) and Main Stream (Event).
Select “Menu > Record > Parameters > Record”, and set the resolution of Main Stream (Event) the same
as the one of Main Stream (Continuous).
2. Verify the frame rate is real-time frame rate.
Select “Menu > Record > Parameters > Record”, and set the Frame rate to Full Frame.
3. Check if the fault is solved by the above steps.
If it is solved, finish the process.
If not, please contact the engineer from our company to do the further process.
 When using the device to get the live view audio, there is no sound or there is too much noise, or the
volume is too low.
Possible Reasons:
a) Cable between the pickup and camera is not connected well; impedance mismatches or incompatible.
b) The stream type is not set as “Video & Audio”.
c) The encoding standard is not supported with device.
Steps:
1. Verify the cable between the pickup and camera is connected well; impedance matches and compatible.
2. Verify the setting parameters are correct.
Select “Menu > Record > Parameters > Record”, and set the Stream Type as “Audio & Video”.
3. Verify the audio encoding standard of the camera is supported by the HDVR.
HDVR supports G722.1 and G711 standards, and if the encoding parameter of the input audio is not one
of the previous two standards, you can log in the IPC to configure it to the supported standard.
