Question about eufy SoloCam S340

No, you don't necessarily need to buy the base unit (HomeBase S380) to use SoloCam S340. The SoloCam S340 can operate as a standalone device with 8 GB of internal memory to store recordings, and there are no monthly fees or hidden costs.

However, if you want to benefit from additional features such as extended storage memory and BionicMind's ability to analyse and recognise what's going on in your home, purchasing the HomeBase S380 may be worthwhile.
