eufy Security Video Smart Lock E330 with Chime: features and who it suits

The eufy Security Video Smart Lock E330 combines three things that usually sit separately at a front door: a fingerprint smart lock, a camera and a video doorbell. This pack also includes an indoor chime. eufy's aim is to let you see who is at the door, talk to them and open the lock from one device.

Three devices in one

According to eufy, the E330 brings together a fingerprint smart lock, a 2K HD camera with an f/1.6 lens, and a doorbell. A wide aperture such as f/1.6 lets in more light, which generally helps in dim conditions, and eufy says it gives clear visibility at night. Putting all three functions in one unit means fewer devices to mount and fewer apps.

Five ways to unlock

eufy lists five methods. The fingerprint reader uses what the brand calls an efficient chip and a slim fingerprint film to recognise you quickly. The others are the eufy Security app, voice control through Alexa or Google Assistant, the keypad, and physical keys. The mix of options means guests, family members and you can each use whichever way suits.

Remote control

With the eufy Security app, you can see who is at the door through the doorbell camera, manage the lock and handle access for visitors from anywhere with a connection. eufy notes that push notifications with thumbnail previews need thumbnail images to be temporarily stored in the cloud. That is worth reading in the privacy section of the app before you rely on them.

The indoor chime

The included chime plays through your home when someone rings the doorbell, or when motion is detected at the door, which eufy says is so you never miss a visitor. It has 8 chime tones to choose from, and you can set the volume that suits your home. A plug-in chime is helpful in larger houses where a phone notification could be missed.

Installation and compatibility

The listing doesn't give installation steps or door compatibility details, so use the manual. In general, a lock with a camera built in is larger than a plain deadbolt, so door thickness and clearance around the frame matter.

What to check before you buy

• Door fit: confirm the lock suits your door's thickness, bolt and frame, as the manual describes.
• Wi-Fi at the door: make sure signal reaches your entry point.
• Power: check how it is powered and how battery levels are reported.
• Backup access: keep a physical key somewhere reliable.
• Privacy: think about what the camera sees, including neighbours, and follow local rules on recording.
• Codes and manual: follow local building and fire codes and the manufacturer's instructions for exit doors.
