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 computer 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 the 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 set up 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.
