I have just purchased and set up 3 cameras at my home. I have the Outdoor wired camera and 2 indoor wired cameras.
The sound tends to be low quality, and its very hard to hear some of the sound that the cameras pick up and record. I hope in the future Roku can improve upon this. However, what I am noticing with the 1080p camera recording is a lot of what we are seeing tends to be a bit grainy. Will Roku ever have high definition security camera's available? I think Roku has a high definition camera doorbell, but I didn't see anything for a high definition indoor type camera.
