As far as video doorbells go, the Eufy Video Smart Lock E330 isn’t the best I’ve ever tested. But considering it’s one half of a whole device, it’s pretty decent. The 2K video resolution is clear and detailed with lifelike colours, and the live feed is fast to load. What lets it down is the lack of colour night vision and the limited vertical viewing angle, which means you can’t keep an eye on your doorstep when you’re expecting a package. Plus, as mentioned previously, if you have a particularly deep-set door frame, the horizontal viewing range and night vision will be impacted.
The smart lock half of the E330 is another story. It’s fantastic, incredibly responsive and offers several handy unlocking options. You can unlock your front door using your fingerprint (the fastest and my personal favourite way to unlock), a passcode, the Eufy app, Alexa or Google Assistant (once you’ve linked the device with your chosen smart assistant) and with the good old-fashioned mechanical lock and key, which hides neatly behind the doorbell button. On the downside, there’s no Apple HomeKit support, so you can’t use your Apple Watch or iPhone wallet to unlock.
We had friends staying with us for a few days during the testing period, and it proved a godsend to simply be able to give them a passcode to unlock, allowing them to come and go as they pleased.
In the month that I’ve spent testing the Eufy Video Lock E330, including an average of about three or four locks and unlocks plus around five camera triggers (less than 10 seconds each) per day, the battery remains at 88%. Admittedly, this is considered very light usage. Eufy estimates that it can last up to 120 days with 10 lock/unlock events and 10 motion detection events (up to 20 seconds each) per day. If the battery goes dead before you have a chance to charge it, there is an emergency USB-C slot that can be used with a power bank to get you back inside (assuming you also don’t have a key on you). Plus, the E330’s battery is completely removable, meaning you could simply grab a spare and keep it ready to go.
