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.

In general, the transfer rate in a general local network environment can achieve over 200 kilobytes per second and approximately 10 to 20 pictures per second from a regular environment.

Q How can I keep the Network Camera as private as possible?

A The Network Camera is designed for surveillance purposes and has many flexible interfaces. The user authentication and special confirmation in installation can keep the Network Camera from unauthorized access. You may also change the HTTP port to a non-public number. The demo account is good to separate guests from normal users and thus you can easily block guests anytime. You can check the system log to examine any abnormal activities and trace the origins.

Q Why can I not access the Network Camera when I setup some options in the application?

A Since the Network Camera is a "network camera", any incorrect network settings will make it inaccessible. If this happens, restore the factory default settings following the procedures in Appendix A.
