Product Overview
The Reolink Wireless Doorbell (Battery-Powered Version) is designed to work without wired installation: it runs on a 7000mAh battery and connects via Wi-Fi, while also supporting existing 8-24V AC/24V DC doorbell wiring. Its image uses a 1:1 square format, with an official resolution of 2048×2048 (4 megapixels) @15fps, with both horizontal and vertical viewing angles at 150° and a diagonal viewing angle of 180°.
The square field of view is a key design feature for a doorbell: when a visitor stands at the door, their entire body from head to toe, along with packages on the ground, can be captured in one shot without relying on a wide-angle fisheye lens that distorts the image. The official lens is a fixed-focus f=1.2mm F1.8 lens paired with a 1/3.11" CMOS sensor.
For audio, the official specifications state that it has 2 built-in microphones and 1 speaker, with support for two-way audio, noise reduction, and echo cancellation — a difference that is particularly noticeable during actual conversations. It supports up to 256GB microSD cards, has an IP65 rating, and weighs 231g.

1:1 Square Image and 150° Field of View
The 2048×2048 square image provides a 150° horizontal and 150° vertical field of view, with a 180° diagonal viewing angle. This means a person standing 1 meter from the door is captured from head to toe, while packages placed on the ground are also visible without needing to deliberately angle the lens downward.
The advantage of the square format is that it does not waste pixels on the walls to the left and right. Traditional 16:9 doorbells often let you “see the person but not their feet”; this model avoids that problem.

7000mAh Battery and Dual Power Supply Options
The 7000mAh battery is rechargeable via USB Type-C, while the doorbell also supports 8-24V AC/24V DC wired power. If your home already has a doorbell transformer and wiring, you can connect it directly without having to remove the device periodically for charging.
This is often overlooked when choosing a doorbell: a wired setup does not require charging, but you need to confirm that your existing doorbell transformer's voltage is within the 8-24V AC range. Before placing an order, you can send us a photo of the transformer label for verification.
- 7000mAh Rechargeable Battery
- Supports 8-24V AC/24V DC Wired Power
- USB Type-C Charging
Dual Microphones and Noise Reduction
The official specifications state that it has 2 built-in microphones and 1 speaker, with support for two-way audio, noise reduction, and echo cancellation. The two microphones help focus audio pickup and reduce ambient noise, allowing the other party to hear more clearly during actual conversations.
A doorbell’s audio quality often has a greater impact on the user experience than image quality: when there is traffic noise, wind, or corridor echo outside the door, single-microphone models can make conversations difficult to hear. This model’s dual-microphone design is intended to address exactly that issue.
- 2 Built-in Microphones+1 Speaker
- Noise Reduction and Echo Cancellation
- Supports Quick Replies
Detection, Notifications, and Quick Replies
Official smart detection includes motion, person, vehicle, and package detection, and supports visitor notifications and Rich Notification (requires a Reolink Cloud subscription). Package detection is especially useful for online-shopping households in Hong Kong — you’ll be notified when someone leaves a package at your door.
Quick Replies let you play a preset voice message when you’re unable to answer, such as "Please leave it at the door, thank you."
- Person / vehicle / package detection
- Rich Notification (requires cloud subscription)
- Preset voice messages for Quick Replies
Storage & App
Supports up to 256GB microSD, with recording triggered by detected events. Can be used with Reolink Cloud (in selected regions) for cloud backup.
The App supports live viewing, two-way audio, playback, push notifications, and Quick Replies; compatible with Google Assistant and Alexa; Wi-Fi supports 2.4GHz / 5GHz.
- Up to 256GB microSD
- Google Assistant / Alexa
- Dual-band Wi-Fi
IP65, Dimensions & Installation
Officially marked IP65 certified and suitable for outdoor use; dimensions are 160×48×29.5mm and weight is 231g. It is slightly thicker than most doorbells, so make sure there is enough flat surface beside the door frame before installation.
Operating temperature: -10°C to 55°C; humidity: 10%-90%. Hong Kong is humid, so adding waterproof sealant around the wiring is recommended. For the battery version, make sure the rubber plug on the charging port is securely closed.
- IP65 certified
- 160×48×29.5mm/231g

Frequently Asked Questions
What is the main difference between the battery-powered and PoE versions?
Power supply and wiring. The battery-powered version uses a 7000mAh battery or existing 8-24V AC doorbell wiring and connects via Wi-Fi; the PoE version requires a single Ethernet cable for both power and data transmission. If there is no network cable outside your door, choose the battery-powered version; if you can run an Ethernet cable, the PoE version is more stable.
What are the benefits of the 2048×2048 square format?
With both horizontal and vertical viewing angles of 150°, visitors are captured from head to toe, and packages on the ground remain in view. There is no need to deliberately tilt the camera downward, and unlike 16:9 models, you will not see the person but miss their feet.
Does it have to be charged? Can it be connected to an existing doorbell wire?
It supports 8-24V AC/24V DC wired power. If your existing transformer is within this range, regular charging is not required. Before placing your order, send us a photo of the transformer label so we can confirm the compatibility.
Do dual microphones make a real difference?
Yes. When there is traffic noise, wind noise, or corridor echo at the door, the dual microphones and noise reduction help the other party hear more clearly. This is one of the most underestimated aspects of the doorbell experience.
How does package detection work?
Package detection is officially supported and notifications are sent when a package is detected. Rich Notification requires a Reolink Cloud subscription (in some regions). If you frequently shop online, this feature is very useful.
What recording mode does it use?
Motion-triggered recording, not 24/7 continuous recording. Continuous recording is not practical for the battery-powered version.
What is the maximum microSD card capacity supported?
The official maximum capacity is 256GB. A high-endurance surveillance-grade card is recommended.
Can IP65 be used fully outdoors?
Yes, it can be used outdoors, but basic shelter is recommended, such as a door canopy. Avoid prolonged direct exposure to rain, and make sure the rubber covers on the ports are securely closed.
Does Wi-Fi use 2.4G or 5G?
It supports dual-band Wi-Fi. If the door is far from the router, 2.4GHz is recommended for more stable wall penetration.
Is it compatible with Google/Alexa?
It supports Google Assistant and Alexa. Some models can display the door view on smart displays. Actual support depends on the model and region.
Want to confirm whether the battery-powered or PoE version is right for your door?
Send us a photo of your doorway, including the doorbell location and door frame, and let us know whether existing doorbell wiring is available. We will recommend the right version and installation method.
