of users, it is recommended to build another web server to host the retrieving contents 

from the Network Camera. 

Q How fast is the video rate of the 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/detailed objects and movement in view, 

5. The level 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 

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 device", any incorrect network settings will 

make it unreachable. If this happens, restore the factory default settings following the 

procedures in Appendix A.
