Q: The images are of poor quality, how can I improve the image quality?
A1: Make sure that your computer’s display properties are set to at least 15-bit
color. Using 16 or 256 colors on your computer will produce dithering artifacts in
the image, making the image appear to be of poor quality.
A2: The configuration on the Internet Camera image display is incorrect. Through
the Advanced>Configuration section of the Web management you need to
adjust the image related parameters such as brightness, contrast, hue and
power line frequency for fluorescent light . Please refer to the
Advanced>Configuration>Video section on Page 35 and 36 for detailed
information.
How to PING Your IP Address
The PING (Packet Internet Groper) command can determine whether a specific
IP address is accessible by sending a packet to the specific address and waiting
for a reply. It can also provide a very useful tool to confirm if the IP address
conflicts with Internet Camera over the network.
Follow the step-by-step procedure below to utilize the PING command but first
you must disconnect Internet Camera from the network.
Start a DOS window.
Type ping x.x.x.x, where x.x.x.x is the IP address of the Internet Camera.
The replies, as illustrated below, will provide an explanation to the problem.
