According to our information, the set of 2 does not include any additional accessories. Due to different purchase prices, such suppliers may unfortunately be available. In such cases, it is of course better to order 2 × a single product.
Yes, the product works with the eufy HomeBase 3. It can either be connected directly to the Wi-Fi or paired with the HomeBase 3 to use additional functions such as advanced face recognition.
You can also operate it with Wi-Fi only. In this case, the internal memory is used until it is full. Then it will be overwritten. And the connection of the cameras then depends on the distance to your router and not on the base station.
Thanks for the tip, I have just reported the error. The eufy S220s connect via WLAN. If we have the item twice in the range (possibly due to an import version), I would of course simply order the cheaper version.
No. It only requires an app from eufy.
The advantages and disadvantages are individual, as it is better this way for one person and that way for another.
My opinion: a Home Base would be an additional device. Therefore more of a disadvantage.
