Eufy Video Smart Lock E330 review

As someone who reviews security tech like smart locks and video doorbells for a living, I have a constantly rotating roster of devices that deck out my front door. While it is fun to test all these gadgets, keeping track of which one uses which app can get a little confusing, and not all of them play nicely together. So you can imagine how excited I was to try the Eufy Video Smart Lock E330, which promised to combine both a smart lock and video doorbell in one, thus leaving you with less clutter on the front door and just one app to manage all its functions. The only problem is that this product is really only suitable for a particular niche, and if your front door setup doesn’t meet all the requirements, you’ll be left with some serious compromises.

The Eufy Video Smart Lock E330 is remarkably sleek and compact for a two-in-one device. It’s not any bulkier than your standard smart lock or video doorbell, which is a pretty impressive feat. It’s rated IP65 weatherproof and can operate in temperatures up to 70°C, so it can comfortably handle hot Aussie summers and rainy days. The only design aspect I’m not a fan of is that it’s hard to see the keypad and to find the doorbell button when it’s dark, as the keypad needs to be touched to light up, so nighttime visitors may get a little confused.

Thankfully, installing the E330 is pretty foolproof—especially if you have experience installing smart locks. Simply remove your existing deadlock then follow the instructions via the Eufy app to install both the interior thumb turn panel and the exterior panel, which houses the keypad, mechanical keyhole, fingerprint scanner and camera. All in all, it took me about 10 minutes from start to finish. However, you will need to give the unit a good charge before installation.

The big issue with the Eufy Video Smart Lock E330 is that it requires a particular front door setup to work as it should. In addition to having a standard door and deadbolt, that deadbolt must be at least 45mm vertical distance between it and your door’s handle. Additionally, the camera’s night vision quality and horizontal viewing range will be compromised if you have a particularly deep door jamb. Worst of all (but not surprising), the Video Smart Lock isn’t compatible with screen doors. Unfortunately, I, like many Australians, do have a screen door. As such, the only way for me to properly test the E330 was to leave the screen door open at all times, which obviously isn’t an ideal solution.

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.

I really wanted the Eufy Video Lock E330 to be the solution to all my cluttered-door, multiple-app problems. For the lucky few who have the ideal front door setup, it absolutely will be. The smart lock is snappy and versatile, the camera is great quality and the device itself is stylish and simple to install. Unfortunately for my screen-door-having self, I’ll still have to keep my lock and my video doorbell separate.
