Bought one of these cameras several months ago and decided to get another based on the performance of the one I had. Both are now working well for me. Night vision shows good images and day time images are crisp and clear. Picking up sounds and using this for two-way communication is exceptional. This camera picked up voices when I replayed the saved Video that I could not distinguish when I originally heard them. Very surprising but that demonstrates how well the microphone and speakers work. Excellent purchase and a really good price.
