the time-server if the Network Camera is connected to the Internet and the function is enabled. Differences of several hours may result from the time zone setting.

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 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 Network Camera. However, it only affects the HTTP mode of 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" shown below the image, check the sound card in your PC and make sure media options in client settings containing audio. 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.
