FCC Certifications This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. [. . . ] Color: Select either for color or monochrome video display. Size: There are three options for two video sizes. "Half" is the quarter size of "Normal". "Half x 2" has the same video size as "Normal" but of a lesser quality, while consuming less network bandwidth. "Video codec type": The user can select either MPEG-4 or MJPEG. In MJPEG mode, the video frames are independent. In MPEG-4 mode, there are I frames and P frames. To decode a P frame the information of previous frame is needed. MPEG-4 consumes much less network bandwidth than MJPEG. There are five dependent parameters that can be adjusted for video performance. Maximum frame rate: This limits the maximal refresh frame rate, which can be combined with the "Video quality control" to optimize bandwidth utilization and video quality. If the User wants to fix the bandwidth utilization regardless of the video quality, choose "Fix bit rate" and select the desired bandwidth. MPEG-4 video is composed of I frames and P frames, as in the following sequence: IPPPPPIPPPPPIPPPP. "Key frame interval" determines how many repeated P frames will appear after one I frame. A large "Key frame interval" can reduce the bit rate, but can also cause greater image corruption if there is packet loss during transmission. The "Fix bit rate" and "Key frame interval" options are only available in "MPEG-4" mode. The video quality may be poor due to a maximum frame rate within the limited bandwidth of the network when images are moving rapidly. Consequently, to ensure detailed video quality (quantization rate) regardless of the network, it will utilize more bandwidth to send the maximum amount of frames when images change drastically. Check both options (Flip & Mirror) if the network camera is installed upside down. "Improve efficiency in the multi-user environment": Check this option to improve efficiency in a multi-user, lowbandwidth environment. Please note that this will cause each connection to slow once a connection has been established. 39 <url> http://<Network Camera>/setup/video. vspx <Network Camera> is the domain name or original IP address of the Network Camera. 40 Image Settings Click on "Image Settings" and a window will pop up that allows you to tune the "Brightness", "Contrast", "Hue" and "Saturation" for video compensation. Each field has a range of eleven levels from -5 to +5. [. . . ] To enable remote viewing over the Internet for your camera, you will need to open virtual server ports on your router. The steps outlined below should be similar for most routers: i. Once you have located the "Virtual Server" (or similar) section, select the "By Port" method if this option is available. Select "TCP" in the "Port Type" field. [. . . ]
