- Live view gets stuck when video is output remotely via the Internet Explorer or a platform software.
Possible Reasons:
a) Poor network connection between the NVR/DVR and the IP camera, and there exists a packet loss during the
transmission.
B) Poor network connection between the NVR/DVR and the PC, and there exists a packet loss during the
transmission.
C) The performances of the hardware are not good enough, including CPU, memory, etc..
Steps:
1.Verify that the network between the NVR/DVR and the IP camera is connected.
1) When the image is stuck, connect the RS-232 ports on the PC and the rear panel of the NVR/DVR with the RS-
232 cable.
2) Open the Super Terminal, and execute the command of “ping 192.168.0.0 –l 1472 –f” (the IP address may
change according to the real condition), and check if there exists a packet loss.
NOTE: Simultaneously press “Ctrl” and “C” to exit the ping command.
2. Verify that the network between the NVR/DVR and the PC is connected.
1) Open the cmd window in the Start menu, or you can press “R” shortcut key to open it.
2) Use the ping command to send a large packet to the NVR/DVR, execute the command of “ping 192.168.0.0 –l
1472 –f” (the IP address may change according to the real condition), and check if there exists a packet loss.
NOTE: Simultaneously press “Ctrl” and “C” to exit the ping command.
3. Verify that the hardware of the PC is good enough.
Simultaneously press “Ctrl”, “Alt” and “Delete” to enter the windows task management interface, as shown in the
following picture.
- Select the “Performance” tab; check the status of the CPU and Memory.
- If the resource is not enough, please end some unnecessary processes.
4. Check if the fault is solved by the above steps. If it is solved,
fi
nish the process. If not, please contact the
manufacturer of the IP camera.
- When using the NVR/DVR 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) The cable between the pickup and the IP camera is not connected well; impedance mismatches or is
incompatible.
b) The stream type is not set as “Video & Audio”.
c) The encoding standard is not supported by the NVR/DVR.
Steps:
1. Verify that the cable between the pickup and the IP camera is connected well; that the impedance matches
and is compatible. Log in to the IP camera directly, and turn the audio on, check if the sound is normal. If not,
please contact the manufacturer of the IP camera.
2. Verify that the setting parameters are correct.
Select “Menu> Record> Parameters> Record”, and set the Stream Type as “Audio & Video”.
3. Verify that the audio encoding standard of the IP camera is supported by the NVR/DVR. The NVR/DVR 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 to the IP camera to configure it to the supported standard.
4. Check if the fault is solved by the above steps. If it is solved,
fi
nish the process. If not, please contact the
manufacturer of the IP camera.
