I've got a pool of two types of cameras, DLink DSC-942L and Foscam C1, connected them to Blue Iris, got no problem, except setting up talk. The audio only works one way. I am able to listen to the cameras audio, but pushing the talk button makes the sound from my PC microphone come to the computer speakers instead of being sent to the cameras. I tried everything possible in the setup of both the cameras and Blue Iris that looked like related to the question, to no avail. Has anyone got a success with two way audio with DLink/Foscam? Any idea how to fix it? The talk works correctly from the cameras' own webpages.
