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. [. . . ] 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. When the image is at the desired quality, press "Save" to confirm the image settings. Click on "Restore" to recall the original settings without incorporating the changes. 41 CCD Settings Click on "CCD Settings" and the CCD settings window will pop up. Therefore the "Auto electronic shutter" (AES) option will be fixed at 1/60 (1/50) second. When the shutter is selected as "Auto", the IRIS of the CCD will become fixed. A faster electronic shutter helps in viewing fast moving objects more clearly. Checking "Low lux mode" helps in viewing objects in poorly lit areas. When "Auto switch to B/W in low lux mode" is checked along with "Low lux mode", the video will automatically become black and white if the camera is in a darker environment. Please note that the HNC800PTZ is not a night-vision or infrared camera, so it will not provide a good picture in total darkness. The "Enable BLC" option is for back light compensation (BLC). Thus, checking this option and adjusting the "BLC sens level" can help in viewing objects more clearly. [. . . ] Therefore, you will still be able to access the camera and all other clients on the local area network from within the network. If your router's public IP address is dynamic, you can also sign up for a DDNS service that will keep the domain name constant. ) 75 5. Use Port Mapping to Assign Virtual Server Ports Typically, there is an "Advanced Setup" (or similar) section on the router's web page where you can find a "Virtual Server" or "Port Mapping" sub-section. To enable remote viewing over the Internet for your camera, you will need to open virtual server ports on your router. Once you have located the "Virtual Server" (or similar) section, select the "By Port" method if this option is available. [. . . ]
