Top complaints
eufy Security Video Doorbell E340
- Battery drains fast
Wirecutter says the internal battery died in less than two weeks, probably because of the two lenses. Several low-star Walmart reviews say it doesn't last a month, including one that needed a recharge 17 days after install.
- Overheating, chime and Wi-Fi trouble
Two 1-star Walmart reviews say it overheats in the sun, shuts down and goes offline. Other Walmart owners report the chime not ringing and failed Wi-Fi setup. Amazon's summary calls reliability mixed.
- Middling privacy score and a past security incident
Consumer Reports gives it only midlevel privacy and video scores. In December 2022, TechRadar reported that Anker confirmed security flaws in its eufy cameras: the Doorbell Dual's live feed could be opened via a URL with no password, and push-notification thumbnails went through the cloud. PCMag also notes there's no HomeKit or IFTTT support.
Arlo Video Doorbell 2K (2nd Gen)
- Subscription needed to see recordings
PCMag says local storage isn't an option, and you need an Arlo Secure plan to view recordings and unlock smart alerts. Consumer Reports says there's no free cloud storage and many smart features need a plan. Walmart 1-star reviewers complain about subscription charges.
- Connection, pairing and battery failures
Amazon's summary says some owners report frequent internet connection issues, faster-than-expected battery drain, and units that stopped working after a few weeks. Low-star Walmart reviews describe failed pairing, random disconnects, a battery that wouldn't charge, and no luck with an existing chime.
- Weak privacy, no color night vision
Consumer Reports gives it top marks for security but calls its privacy weak. PCMag notes there's no color night vision and no Apple HomeKit support.
