This concerns a bundle consisting of the Eufy S220 SoloCam and the Eufy Doorbell Slim.

Description Eufy S220 SoloCam:
The Eufy S220 SoloCam is an outdoor IP camera. This IP camera has a built-in battery and can charge on solar energy. This means it takes longer to recharge the battery. With 3 hours of direct sunlight per day, the camera will last an extra day on the battery. Without direct sunlight, you can charge the battery on average every 3 months. The camera records in a sharp 2k resolution, so you can zoom in and see faces clearly. The IP camera detects movement and keeps people, animals and movements apart. You will receive a notification via the app. You can also talk back to a visitor via this app. Installation is very easy because the Eufy S220 is wireless, you don't need a Homebase to install the camera.

Description Eufy Doorbell Slim:
The Eufy Video Doorbell Battery Slim is a smart doorbell with chime that stores footage locally. You place the gong in a socket, after which you hear through the app as well as in the house that someone is at the door. In addition, the gong stores camera images locally, after which you view them in the app via an encrypted connection. You can also communicate directly with the person in front of the door via this app. This doorbell works on a rechargeable battery that lasts about 4 months. This makes it easier to install than wired doorbells. The Video Doorbell Battery Slim works with Alexa and Google Assistant.
