build another web server to host a large quantity of users by retrieving contents from
Network Camera periodically.
Q How fast is the video rate of Network Camera?
A The MPEG4 codec engine can process 30 frames per second internally. However the
total performance is subject to many coefficients as follows:
1. Network throughput,
2. Bandwidth share,
3. Number of users,
4. The complicated objects and movement in view,
5. The level of your PC or notebook which 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 of a normal environment
per second.
Q How can I keep Network Camera as private as possible?
A Network Camera is designed for surveillance purposes and has many flexible
interfaces. The user authentication and special confirmation in installation can keep
Network Camera from unauthorized access. You may also change the HTTP port to
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 Network Camera when I setup some options in the application?
A Since Network Camera is a "network camera", any incorrect network settings will
make it unreachable. Once the system is missed due to wrong configuration, restore
the factory default settings following procedures in Appendix A.
