Appendix A Frequently Asked Questions
Q: What if I forget my password?
A: Every access to the IP camera needs authentication, unless the admin password is set up as
blank. If you are one of the managed users, you will need to ask the administrator for the
password. If you are the administrator, there is no way to recover the admin password. The
only way to regain access to video encoder is to utilize the RESET button on the top panel
to restore the factory settings (see Chapter 1 for details).
Q: Why can’t I see video from the IP camera after it has been authenticated?
A: There are many possible scenarios:
1. If you have installed the IP camera correctly and the LEDs appear normal, check to see
if the camera module (lens and CCD module) is tuned properly.
2. If the IP camera is installed correctly and you are accessing the IP camera for the first
time using Internet Explorer, adjust the security level of Internet Explorer to allow
installation of plug-ins.
3. If the problem still exists, the number of users accessing the IP camera at the same time
may exceed the maximum that the system allows.
Q: What is the plug-in for?
A: The plug-in provided by IP camera is used to display motion pictures. The plug-in is
needed because Internet Explorer does not support streaming technology. If your system
does not allow installation of plug-in software, the security level of the web browser may
need to be lowered. It is recommended that you consult the network supervisor in your
office before adjusting the security level.
Q: Why is the timestamp different from the system time of my PC or notebook?
A: The timestamp is based on the system time of the IP camera. It is maintained by an internal
real-time clock, and automatically synchronizes with the time server if the video encoder is
connected to the Internet and the function is enabled. Differences of several hours may
result from the time zone setting.
Q: Why doesn’t the image refresh regularly?
A: This may be due to the time it takes to store recorded video and snapshots into memory, or
the time it takes to send the images to the SMTP and FTP server when events occur.
