This isn't my first security camera, and here I picked this model in the hope that I could go completely without a wired connection: not even a power supply. On arrival everything is plastic but really good quality. However, it was not strictly necessary, but it is very aesthetic and feels absolutely comfortable. Beautiful object. A fairly simple and modern look for a rather small size considering its possibilities. During the installation of the camera, I powered it with a small portable battery. This wasn't strictly necessary as we don't have a traditional camera here, accompanied only by its solar panel. Although our product is equipped with an internal battery, I have not found any information to know what its capacity is. In use, everything works quickly and easily. Since the camera is placed high up, we can distinguish (at least one silhouette) at about ten meters at night. With the app on your phone, you can easily save camera screenshots. On the other hand, it is not easy to find them afterwards. It shouldn't really vary from phone to phone. In the end, the product seems to me to be a little more successful than the competition in several respects.
