Q Can I install it on ceiling?

A Yes. There are flip and mirror options in 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 is 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 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 the period, users 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 setup and names are given, check to see if the

function is checked at 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 properly installed. If "AV" is shown, check the audio source of the Network Camera.

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 maximum ten (10)

users to watch and listen to the Network Camera at the same time. For a larger number
