I think the writeup about the video clearly says you can only see inside the house “for several seconds” before it goes dark. You can continue to hear the sounds. Sorry you were disappointed, but the attempt was made to accurately describe what is in the video.
Yeah, it’s sort of like, “Let me show you a video of me sleeping at night...” [the lights are off, the video is dark and all you hear is just the snoring... LOL...]
