About the eufy Security Video Doorbell 2K (Battery-powered)

Ned O.

Look smart

The eufy Video Doorbell 2K lets you see who's at your door, whether you're at home or away. It also operates as an intercom, so you can tell your friends to come around back, or confirm that it's okay to leave a valuable delivery on your front stoop.

Look smart

The eufy Video Doorbell 2K lets you see who's at your door, whether you're at home or away. It also operates as an intercom, so you can tell your friends to come around back, or confirm that it's okay to leave a valuable delivery on your front stoop.

Onboard AI recognizes and prioritizes human figures, so you'll only get alerts on your smartphone when visitors — or intruders — show up, but not every time the cat saunters by. The built-in camera captures high-def 2K video with wide dynamic range (WDR), so you'll see clear images of whatever it picks up.

Free local storage and flexible power options

One of the biggest advantages of the Doorbell 2K is that all your security footage is privately stored inside your home on a 16GB memory built into the HomeBase. This separate device connects to your network router and also acts as a charging station and intercom. Local storage means there's no monthly fee — although optional monthly cloud storage plans are available.

You can power the Doorbell 2K with the built-in rechargeable battery, which can last up to six months. Or you can connect it to your existing doorbell wiring for hassle-free continuous power.

App and voice control

The eufy Security app for iOS® or Android™ guides you though system setup. Simply connect the HomeBase via Ethernet for the initial connection to your network — after that, it can use your Wi-Fi. Then add your Doorbell 2K and any additional cameras.

The app also allows you to customize several settings. For example, if you live in a busy neighborhood, you can draw up to three Activity Zones, to keep kids playing or neighbors strolling by on the sidewalk from triggering alerts. You can also set the motion detection sensitivity level.

For hands-free control, you can use Google Assistant or Amazon Alexa devices (sold separately). Just ask your voice assistant to show you what's happening at your Doorbell 2K, and see it right there on your smartphone screen.

More details on the eufy Security Video Doorbell 2K (Battery-powered)

Mark G.

Product Research


Overview: The eufy Video Doorbell 2K (Model T8210) lets you see who is at your door in HD clarity. The Video Doorbell can operate on the built-in battery or hardwired into existing doorbell wiring. In addition to the Video Doorbell, the package includes HomeBase 2, which stores your video clips and doubles as the doorbell chime. The camera and HomeBase connect wirelessly to each other, and the HomeBase to Wi-Fi. Using the Eufy Security app, you can receive notifications whenever someone approaches your door, and view live video from the video doorbell on your smartphone or tablet. The Video Doorbell is also compatible with Amazon Alexa and Google Assistant. Dimensions: Width 2.136", Height 5.512", Depth 1.114".

Doorbell Camera: The Video Doorbell 2K is equipped with a Sony image sensor which produces beautiful 2K video. Its 4:3 aspect ratio (2590 x 1920) provides an expanded field of view, particularly vertically, which gives you a full head-to-toe view of your visitors. The camera's Wide Dynamic Range (WDR) lets you see sharp details, especially with a brightly lit background.

Mounting: The doorbell comes with a bracket for surface-mounting the doorbell. The recommended mounting height is 48" from the ground. A 15° mounting wedge is provided to aim the camera toward the center of the door, which may provide a better viewing angle of a visitor at your door. When you have determined the mounting location, you can mark the screw holes using the provided Screw Hole Positioning Card. Screws and wall anchors are provided for mounting the bracket to the wall. Tools required for mounting the doorbell include a Phillips-head screwdriver, a power drill, and a 15/64" drill bit. The Video Doorbell 2K is lightly waterproof, but it is recommended that it be mounted under a shelter.

Smart Detection: Artificial Intelligence (AI) and a sophisticated algorithm built into the system can instantly analyze the body shape and face patterns of approaching visitors to detect only human activity. This helps prevent alerts being sent when the neighbor's dog passes through the yard. In the Eufy Security app, you can draw a customized motion detection Activity Zone to eliminate false alerts from high traffic areas on the street or sidewalks.

Power Options: The Video Doorbell has several power options. For homes with no existing doorbell wiring, you can operate the doorbell on the built-in 6500mAh rechargeable battery. A fully charged battery will last approximately 6 months, based on 10 doorbell events per day, and each recording lasting about 20 seconds on average. You can charge the battery with a 5V USB power port. A charger with a 1A output, it takes about 6 hours to charge the battery from 0% to 100%. With a 2A charger, such as the USB port on the back of the HomeBase 2, the charging time is about 3 hours. Another option if you do not have existing wires would be to purchase a doorbell power adapter for continuously charging the battery. the power adapter should have an output of 24V/500mA, 18V/500mA, or 16V/800mA. If there is existing 8-24VAC, 10VA (or above) doorbell wiring, you can hardwire the doorbell for continuously charging the battery. If the existing wires are too short, two wire jumpers and wire nuts are provided to extending the wiring.

HomeBase 2: The included HomeBase 2 contains 16 GB of built-in storage which can store up to 180 days of video clips (based on thirty 20-second video clips per day). It is not expandable or replaceable, nor is there a slot for a memory card. HomeBase 2 has military-grade 256-bit data encryption to protect your video footage safe during transmission and storage. The Video Doorbell communicates with the HomeBase via SUB 1G Wi-Fi, and should be within 20-30 feet of each other. HomeBase works with 2.4 GHz Wi-Fi (not compatible with 5 GHz band), or connects to your home router via the provided Ethernet cable. HomeBase 2 has a built-in speaker that can be used as the doorbell chime. It is powered by an AC adapter. Dimensions: Width 3.212", Height 5.188", Depth 3.224".

Eufy Security App: The Eufy Security app lets you view live video from your smartphone or tablet, plus engage the visitor at your door through two-way audio. You can also record three instant responses that you can use if you don't want to engage with your visitor live. The app is compatible with Android devices running operating system 5.0 and up, and iOS devices running iOS 11.0 or later. The Video Doorbell can be viewed on a web portal instead of your phone, and on Macs running macOS 11.0 or later and a Mac with Apple M1 chip.

Voice Assistants: The eufy Video Doorbell 2K can be connected to Amazon Alexa or the Google Assistant so you can see what's happening outside your door at any time. Smart displays, such as the Google Nest Hub or the Amazon Echo Show, you can ask Alexa or Google to "show me the front door" and you'll be able to view live video from the Video Doorbell. In addition, any Amazon Echo voice assistant can be used as a doorbell chime, if desired.

How do we prevent thieves from stealing the doorbell away? (Wireless, not wired model)

There's a locking tab that holds the cover in place so the screw heads are not accessible. Comes with a pin tool so you can open the cover if need be.
