Having confidence in this brand and already having several cameras in my possession, I chose this model because it can work on batteries and solar panels and without an outlet, offers the possibility of being able to view them remotely from the same application, and also because of the full duplex audio to chat with people. High quality camera that is easy to set up: you press a button and scan the QR code in the K&F Concept application. After a few moments, the camera will announce that it has successfully established a Wi-Fi connection. The connection to the WiFi network is very stable even at a certain distance from the router or repeater (tested outside of 20 m from the Netgear Nighthawk AX1800 repeater in the garage). The picture quality is very good. H24 7/7 Max 60 seconds Recording to cloud or SD card only activates when motion is detected to save bandwidth and battery. The IR illumination can be automatically activated or completely deactivated depending on the lighting conditions (public lighting, low light, fog, etc.). Once configured, it can be used on the go without WiFi and without a solar panel, for example during a power outage. Hidden for regular surveillance of objects (from theft), of course remember to charge the battery via USB and insert an SD card. Playing videos is very easy with the application on iPhone or Mac (not tested on Windows). Probably the best camera currently. I have no negative comments for now.
