Burglars often enter residences via the main entrance during intrusions. A video doorbell serves as an essential security measure, and the Eufy Video Doorbell E340 offers this safeguard at a reduced price of $90 during Cyber Monday.

Normally priced at $150, this device boasts numerous capabilities, including a 2K main lens paired with an additional downward-facing camera designed to monitor parcels placed at the doorstep. According to our evaluation, the E340 excels in minimizing erroneous motion notifications, aided by its integrated thermal sensor that detects human body warmth.

For homes with a pre-installed doorbell power supply, the Eufy E340 can wire directly to it, eliminating battery recharging concerns. Lacking such a setup is not an issue, as it includes a built-in 6500mAh battery. With 8GB of internal memory, users can access event footage without a paid service plan. Alternatively, if equipped with Eufy's HomeBase 3 NAS unit, the device can save videos there.

The Eufy E340 has limited integration with Google Home devices and lacks support for Apple Home, though it integrates seamlessly with Amazon Echo speakers and screens.
