already own several solar cameras and this is my second model from this brand. When selecting the cameras, I make sure that they run with the CloudEdge app. Then all cameras can be easily added and operated intuitively with the successful app. The K&F Concept camera is well made and there are hardly any differences to the cameras from other brands that I own. German instructions and the necessary assembly material are included. Adding the camera via the Cloud Edge app and setting it up is easy. Once the app is set up, all you have to do is hold the QR code generated by the app in front of the camera and wait for the confirmation, done. A cloud subscription is not necessary. But I recommend inserting a micro SD card. The Cloudedge app then offers all the settings you need, such as motion alarms, a chronicle of alarms in a clear timeline, live image, alarm settings, etc. You can view every movement, which by the way is recorded with an image, in the timeline again and again and if you have a micro Inserted SD card, there is also a small video about it. The camera also records sound with films and you can use the camera as an intercom. But the sound quality is only mediocre... There is also a light and an alarm. Of course, every video and every picture has a time/date stamp. You can choose between SD and a higher resolution. The picture quality in general and the night vision are good and absolutely sufficient. You can also pan and rotate the camera via the app, which also works well. The notification of movements on the cell phone works reliably, but an alarm has sometimes not been triggered. In general, this works well and the sensitivity is also adjustable. From my experience with other cameras that I have been using for a longer period of time, I can report that the solar panel is almost sufficient to supply the camera with electricity all year round. So far I've only had to supply two cameras with additional power once in a year. A good place for the solar panel is important. The built-in battery could become a shortcoming at some point, so if it should give up the ghost, you can throw the camera away. But as I said, my other cameras have lasted for over a year... Conclusion: Here too you get a very good solar camera with useful functions, many setting options and a really good app. The resolution and night vision are good, the sound quality is mediocre and the motion detection is good. The solar panel should be enough to supply the camera with enough power for most of the year. Iran saves laying the annoying cable here, but you have to place the solar panel on a good sunny spot, then you might have to help with electricity 1-2 times a year, otherwise the solar panel is sufficient.
