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 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.
Q How fast is the video rate of the Network Camera?
A The MPEG4 codec engine can process up to 30 frames per second internally. However the
total performance is subject to many coefficients such as:
1. Network throughput,
2. Bandwidth share,
3. Number of users,
4. The complicated/detailed objects and movement in view,
5. The power of your PC or notebook that is responsible for displaying images.
