TROUBLESHOOTING

PROBLEM

SOLUTION

When an Windows 10 user accesses 

the web viewer through Chrome 

or Firefox, the sound volume of 

microphone changes periodically.

y

This is what happens when microphone driver has been set to Realtek driver. 

Install the High Definition Audio device (Windows Default Driver) or the third party driver as 

the microphone driver.

No video is displayed when accessing 

the plug-in free webviewer on Safari 

via HTTPS.

y

On the authentication popup window prompted when initially accessing https, click "View 

Authentication Certificate" and select the "Always trust when connecting to the designated 

webviewer IP" check box.

y

If the webviewer continues failing to display a video after you select "Next" on the message 

window below, press the command key + Q to exit the Safari browser, access again and 

follow the procedures stated above.

I can’t access the camera from a web 

browser.

y

Check to make sure that the camera’s Network settings are appropriate.

y

Check to make sure that all network cables have been connected properly.

y

If connected using DHCP, verify that the camera is able to acquire dynamic IP addresses 

without any problem.

y

If the camera is connected to a Broadband Router, verify that port forwarding is properly 

configured.

Viewer got disconnected during 

monitoring.

y

Connected Viewers become disconnected upon any change to camera or network 

configurations.

y

Check all network connections.

No video is displayed when I newly 

access the webviewer or connect 

streaming to the client.

y

The maximum number of profiles available is 3. 

The connection may be lost if you use 4 or more of profiles. 

Example) If you access MJPEG, H264 and H265 and then access with a different profile, the 

connection will be lost.  

The camera connected to the network 

is not detected in the IP installer 

program.

y

Turn off the firewall settings on your PC and then search the camera again.

Images overlap.

y

Check whether two or more cameras are set to a single multicast address instead of different 

addresses. If a single address is used for multiple cameras, the images may overlap.
