Same summary

The Eufy eufyCam E40 two-camera security set allows you to monitor both indoor and outdoor spaces without the need for a constant electrical connection, as it runs on powerful batteries. The higher resolution of 3K recording is suitable for situations where the visibility of people or larger details is important, such as front doors, yards or garages. Battery power and the option of wired or wireless connection bring flexibility in terms of placement, but with intensive recording, it is necessary to plan for regular charging or replacing the batteries. The camera is not best suited for environments where completely continuous use is required without interruptions to maintain power.
