frame rate to 25 fps or 30 fps. If you are shooting fast-moving images, you may want to slow the maximum frame rate down to 20 fps in order to lower the rate of data transmission. This allows for better video quality and the human eye cannot easily detect the differences between those of 20, 25, or 30 frames per second. If your network bandwidth is below 384 Kbps, set the “Fix bit rate” according to your bandwidth and try to get the best performance by fine-tuning the “Maximum frame rate”. In a slow network, greater frame rate results in blurred images. Another work-around is to choose “Half” in the “Size” option for better images, or “Halfx2” for a larger image view. Video quality performance will vary somewhat due to the number of users viewing on the network, even when the parameters have initially been finely tuned. Performance will also suffer due to poor connectivity as a result of the network’s burst constraint.

For Best Quality Images

For the best video quality, you should set “Fix quality” at “Detailed” or “Excellent” and adjust the “Maximum frame rate” to match your network’s bandwidth. If your network is slow and you receive “broken” pictures, go to the TCP protocol in “Connection type” and choose a more appropriate mode of transmission. The images may suffer a time delay due to a slower connection. The delay will also increase as the number of users increases.

Compromise Between Real-time and Clear Images

If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than setting “Fix bit rate”. You can also fix the bandwidth according to your actual network speed and adjust the frame rate. Start from 30 fps down for best results but not below 15 fps. If the image quality does not improve, select a lower bandwidth setting.

Viewing Double-Size Images

The network camera not only provides standard CIF video format, but also 4 x CIF video format. Select “Double” for the video size and you can view more detailed video. But the frame rate will be reduced (only up to 10 frames/sec.). The selection “Normal x 2” will perform a 200% zoom on the height and width of the video.

Protect the Network Camera by Using Passwords

The network camera initially has no default password (i.e., it is blank). This means that initially anyone can access the network camera (including the configuration section) as long as the IP address is known. It is necessary to assign a password if other users will need to have access to the network camera. Type a new word twice in (1) to enable protection. This password is used to identify the administrator. Then add an account with user name and password for other users in (2). The network camera can provide twenty accounts for your additional users. Each account identifies the access right rather than the actual visitor. This allows multiple visitors to share the same account. An option to access DI/DO is provided for each account. Some users may need to be prohibited from controlling your attached devices. Another option allows different controls for the pan/tilt functions of the Network Camera. You may choose to delete users in (3).

More flexible options for viewers (4)

The first option allows anyone who uses “demo” as the user name to view without a password. The Administrator can also decide if more viewers are allowed to watch the video if the number of viewers exceeds the limit. The extra viewers will have snapshot mode instead.
