In a nutshell + no WLAN / electricity required + easy installation + good image quality and functionality + easy to use via app + / - SIM card with data volume means monthly costs If you want to know more, you can 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 the WLAN and power supply. This camera is an exception. It has a solar panel that is included to charge the battery as long as the sun is initially out. The battery should supply the camera with power during the hours of darkness. This works quite well in the test and the camera has no interruptions in my case. Another advantage of the camera is that it is not dependent 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 100 MB - that is not much and must be increased for a fee after use. However, data SIM cards from common network operators can also be installed (but it should 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, as it does not burden the data volume. The camera is controlled via an app - here, as is often the case, I am concerned that data protection and security are not taken very seriously. This should be taken into account when considering the purchase, depending on how sensitive the monitored area is. Everything is included for mounting and the camera is waterproof/dustproof and therefore suitable for outdoor use. Overall, a solid set - my recommendation
