Reference
If we obtain lower frame rate than set we need to check from the system administrator for sufficient bandwidth available or reduce the
•
number of applications running on the client computer.
If the client PC’s are unable to access the multicast stream, check with the system administrator for the use of a valid multicast address or
•
check if the router is supporting multicasting.
If the images appear to have white of gray stripes on it, upgrade the Video graphics driver on the client PC to the latest version.
•
Video images may be noisy if you are using the camera in a very low light environment or the bit rate/quality is set to very low values.
•
Provide higher values for quality and support the surrounding environment with enough light.
Audio condition
The client computer that is interacting with the camera needs to have a sound card that is functional to support speaker and microphone.
The sound card needs to be checked for its support for full duplex communication.
Ensure that the mute button of the client computer is not set and all the audio settings are correct.
Speaker button on the web viewer should be enabled to listen the audio from the network camera.
Ensure that the bidirectional audio button is enabled on the Web viewer and the microphone is set.
Change the input and the output gain for microphone and the speaker respectively to set correct audio level.
For all further support please contact the supplier or forums or websites.
