I have this cam now for several weeks now in use and am very satisfied. I use them for documentation in nature and environmental projects. Picture and sound quality, I feel, considering the price range of the cam, for very good, but I use always an extra microphone. Especially important to me I remotely controlling the Cam with Smartphone or cell phone with wifi function. This works great. You can control the image quality, zoom, focus control, switch between video and image recordings and the outdoors over 100m, ideal for animal photography and documentaries. This cam provides a lot of possibilities in a very good quality of image-video recordings and a reasonable price, I am very satisfied with it and would buy again at any time.
