9. Troubleshooting
Important note:
The video quality depends on the video parameter settings and the network quality. To have a
•
better video quality, select higher resolution and higher frame rates. This is no problem when
viewing videos locally in the same network. When watching a video remotely through the Internet
however, it is important to know the bandwidth of the Internet connection (Internet speed). If the
"Internet speed" setting of a camera is very high, but the real Internet speed (bandwidth) is
relatively low, the video quality could be very bad. Worst case, the video display could be
disconnected. In order to have the best video quality, consider a broadband Internet connection
from your ISP and set the "Internet speed" of the camera a little lower than the real Internet
speed provided by your ISP.
Also note that when multiple users are displaying the same camera at the same time, the
•
required Internet speed is the video bandwidth times the number of users.
Q: The camera status indicator shows a green icon, but I can not view the video or change
the settings.
A: The green icon only denotes that the camera is online and responding, not guarantees that the
video session can be established. The reason is due to a firewall or strict access rules of the router.
Q: The video quality is not that good when I view remotely via the Internet.
A: The video quality is greatly affected by your Internet connection speed. Therefore, it is
recommended to change the bandwidth settings of the camera to a value which is smaller than the
one that your ISP provides you.
Q. The video quality is not good when the status indicator of the IP Cam is yellow. Why is
that?
A: If the status indicator is yellow, it means the connection between CamView and the camera is not
good. There might be a firewall in between or the routers between camera and CamView have strict
access rules.
Q: Can the password for playing video be blank (no password)?
A: No. For security reasons, we do not allow to set the video playing password blank.
Q: Can I change the settings of the camera through CamView?
A: Yes, partially. You can change the resolution, frame rate, bandwidth, microphone, auto select,
indoor/outdoor mode, light frequency, LED mode, and brightness settings of the Cam through
CamView. The rest of the settings can only be configured via the web page of the Cam.
Q. Sometimes connection to the camera fails after changing the settings of the IP Cam.
A: The IP camera needs some time (±5 seconds) to re-initialize the system. Therefore, wait 5
seconds and try to connect. If the auto reconnection is enabled, CamView will reconnect
automatically.
Q: How many simultaneous users are allowed?
A: The maximum allowed video users for a camera at the same time depends on the video settings
including "Internet speed" and resolution. See below for a summary of the maximum allowed video
users:
Resolution
176x120 - 176x144
352x240 - 352x288
720x480 - 720x576
