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.
For best results, the Network Camera is designed to accommodate a maximum of ten
(10) users to watch and listen for streaming video and audio 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.
