As always, the camera was delivered very quickly. I already have two products from this Chinese manufacturer. The following is what I like about the K&F Concept camera: - the image quality is okay both day and night (see pictures) - the intercom system works perfectly. You understand the other person very well (of course, a good internet connection is a prerequisite) - As with the other cameras of this brand, you can buy a memory card once to save the pictures/videos and do not have to pay a monthly fee for it, as with some other providers pay. - The camera reliably detects movements. When it detects movement, a small blue dot lights up in front. So you can see that the camera is recording. What's not so good: - At night, the sharpness of the images unfortunately decreases after a few meters. But what I don't know about other brands is different. However, you can see very far. In the pictures you can see once during the day, once at night and once at night with the light switched on (this can be switched on and off in the app) - if the app's notifications are activated (which is what you usually have with a camera, otherwise nothing is displayed when someone is recognized) the app icon is always there at the top of the phone, with the comment that the resident messaging service has been activated. I personally find it a bit tedious. In short, I think the K&F Concept camera is just as good as one from a more expensive brand. Through the point of saving to memory card, even BETTER than some other cameras.
