Higher frame size, frame rate and bit rate rate gives better video quality. At the same time, it requires more network bandwidth. For best viewing results on a mobile phone, we suggest setting the Frame Rate to 5fps and the Bit Rate to 20 kbps. Mode: It can be either JPEG or MPEG4. In JPEG mode, the video frames are independent. However, MPEG4 consumes much less network bandwidth than JPEG. Frame Size: Three options exist for the sizes of the video display. It is recommended using 176x144 for mobile viewing and 640x480 for computer viewing. Video Quality: This limits the maximal refresh frame rate, which can be combined with the “Fixed quality” to optimize the bandwidth utilization and video quality. If the User wants to fix the bandwidth utilization regardless of the viideo quality, choose “Constant bit rate” and select the desired bandwidth. Internal microphone input gain: you must configure the gain for your microphones. Please note that dB stands for decibels, a unit of audio measurement. More decibels as a positive value indicates that the sound is louder, while more decibels as a negative value indicates that the sound is quieter. Audio type: AAC: (Advanced Audio Coding) A wide band audio coding algorithm that exploits two primary coding strategies to dramatically reduce the amount of data needed to convey high-quality digital audio. Select a higher bit rate number for better audio quality. GSM-AMR: A standard adapted audio codec by the 3GPP video (3rd Generation Partnership Project). It is an Adaptive Multi Rate-Narrow Band (AMR-NB) speech codec. Select a higher bit rate number for better audio quality.        Copyright © 2008 D-Link Corporation/D-Link Systems, Inc.
