GXV3601 IP Camera
Resolution – The higher the resolution is, the better the video quality is, and higher bandwidth is required.
Low
QCIF CIF 2CIF D1 Bit Rate – The number of bits that are conveyed or processed per unit of time. Maximum Frame Rate – The video frame rate is adjustable based on network conditions. Increasing the frame rate will increase the amount of data significantly therefore consuming more bandwidth. Video will be impaired due to packet loss when there is insufficient bandwidth.
Bit Rate Control – Variable Bit rate (VBR) and Constant Bit Rate (CBR).
Variable Bit Rate - If VBR is selected, the codec varies the amount of output data per time segment. VBR produces a better
Constant Bit Rate - If CBR is selected, the codec’s output data is constant regardless of the input data. The output bit rate is defined in “Bit rate”. CBR is useful for streaming multimedia content on limited capacity channels. It is easier to calculate required bandwidth as well as the required storage space using CBR.
Image Quality – If ‘Bit Rate Control’ is set to “VBR”, “Image quality” needs to be configured. The better the video quality is, the higher the bit rate will be.
NOTE: The users might need to configure the Primary Stream and Secondary Stream properly. Sometimes, the user might like to watch the live video stream from the web GUI in low resolution mode while recording a copy via GSurf/GS_NVR in high resolution due to the limitation of internet bandwidth. In this case, for example, primary stream can be configured to have better resolution, and then the users can use primary stream to record while watching secondary video streams.
Audio Settings
Preferred Audio Codec – The GXV3601 supports up to 3 different Vocoder types,
audio can also be turned off by switching the setting to “Disabled”
