If you select a 16:9 resolution underROI, the live image displayed by the camera will be distorted by recording software or a recordersystem, or may not be displayed at all. To solve the problem, you must set a 4:3 resolution in thenetwork camera or ROI: 320x240, 640x480, 800x600 or 1024x768. This may involve cropping theperiphery of the live image.After setting up a ROI only this area will be displayed at live display as well as for RTSP access (e.g usingVLC media player). By transmitting only the ROI bandwidth and storage space is saved.9.6 Audio settings“Mute” All audio functions in the network camera are deactivated. A note appears when you access thenetwork camera.“External microphone/audio amplification” Adjust the value from +21 db to -33 db.“Audio type” Select the audio type and desired bit rate. A higher value requires more bandwidth:• “AAC” (Advanced Audio Coding) Special codec for audio data compression under MPEG-4/H.264.• “GSM-AMR” (Global System for Mobile Communications – Adaptive Multi Rate) Voice codec in GSMmobile telephone network.• “G.711” pmca/pmcu (Pulse Code Modulation).ROI
