Q4:Q21. The playback via remote access is slowly and cannot hear any audio.

"1. When users use remote access to see the live view: images are loaded from cache memory in CIF format. Frame rate of the loaded file depends on the setting in ""HTTP Setup"" of local DVR and the requirement for network is around 1Mbps for DVR upload. 2. When users use remote access to see the recording video in playback: images are loaded from HDD of local DVR, so the transmission size depends on the recording resolution and frame rate. For example, if users set 720x480 with 30 FPS or 720x576 with 25 FPS to record, the result of recording size is huge and LAN is required to connect for playback. In general, the requirement for network is around 10 Mbps for DVR upload. When downloading files from remote access under unqualified Network Speed, a momentary loss of recorded audio signal may occur in order to maintain the images. Consequently, the downloaded files may contain without Audio signal. So if users want to view the playback file with smooth quality, could you please suggest your clients backing up the file to local PC and then playback it again when the Network Speed is unqualified."
