In a nutshell + no WLAN / electricity required + easy installation + good image quality and functionality + easy to use via the APP + / - SIM card with data volume means monthly costs If you want to know more then you can just read on - have fun The security camera Surveillance cameras are on the rise. They are available cheaply and work easily and reliably with apps. Most cameras work via a WLAN connection and are therefore always dependent on WLAN and the power supply. This camera is an exception. It has a solar panel which is included to charge the battery as long as the sun is at the start. The battery should then supply the camera with power for the dark hours. This works quite well in the test and the camera has no dropouts in my case. Another advantage of the camera is that it does not depend on WiFi. You can simply insert a SIM card into the device and access the camera remotely. The set includes a SIM card with a volume of 100MB - that's not much and has to be increased for a fee after use. However, data SIM cards from the common network operators can also be installed (but it must be clear that this is always associated with running costs). For storage, there is either the cloud or a memory card (must be purchased). In my opinion, the memory card makes sense, since the data volume is not burdened. The camera is controlled via an app - here, as so often, I am concerned that data protection and security are not taken very seriously. This must be taken into account when considering the purchase, depending on how sensitive the monitored area is. Everything is included for assembly and the camera is waterproof / dustproof and therefore suitable for outdoor use. Overall a solid set - my recommendation
