Q Can I install it on ceiling?
A Yes. There are flip and mirror options in the video configuration page to correct the
images for upside down installation.
Q The image is not clear enough.
A Rotate the lens to adjust the focus after the Network Camera has been installed in
the proper position. The image settings and white balance can be fine tuned to achieve
the best visual effect. Also notice the power line frequency must match the local utility
to synchronize and minimize the effect of flickering florescent lights.
Q Why does the image not refresh regularly?
A Some anti-virus programs filter the received web content. It takes time to perform
data examination and affect the streaming application such as that of the Network
Camera. However, it only affects the HTP mode of the Network Camera. If the network
allows only HTTP mode, disable the web filtering function of the anti-virus program
temporarily. During this period, the User should be aware of the risk of malicious
network activity.
Q I have opened motion detection windows but it cannot work.
A If the motion detection windows are set up and names are given, check to see if the
function is checked on the first line. While it is enabled, adjust the sensitivity and
percentage to monitor the level indicator for best results.
Q I cannot hear any sound while watching.
A If there is "V_ONLY" shown above the image, click on connection type to uncheck
"Disable audio". If there is "V" shown instead of "AV", the sound card in your PC may
not have been properly installed. If "AV" is shown, check the audio source of the
Network Camera, make sure you are using internal or external microphone.
Q How many users are allowed to watch the Network Camera at the same time?
A Too many users requesting the real-time multimedia content will jam the network.
For best results, the Network Camera is designed to accommodate a maximum of ten
(10) users to watch and listen at the same time. For a larger number of users, it is
recommended to build another web server to host the retrieved contents from the
Network Camera.
