To my own surprise, I really like the K&F Concept 2K surveillance camera. While I'm not a fan of total surveillance, in our case this camera does the job quite well. In our case, it is used in the garden, as there are several pieces of play equipment for our own children and those of the neighbours. That way you can keep an eye on the kids a little more, because you can't always be there all the time. Let's get to the camera itself. The main unit itself was delivered to us in gray and the camera makes a high-quality impression. The supplied solar panel can be connected to the camera with a fairly long cable, so the camera runs without electricity. In order to use the camera, you first have to download the associated app. The app is designed so easily and simply that I didn't have to look at the user manual to get the camera up and running. It couldn't be easier and I'm also totally enthusiastic about the picture and sound quality. Due to the current time of year, I can unfortunately not yet fully assess whether the solar panel will actually do its job in autumn and winter. We're in the process of trying this out and if the camera/solar panel works properly when there's no direct sunlight, then I'll give the thing five stars.
