Product Research
Features
Overview: The Reolink Battery Wi-Fi Video Doorbell (Model D340B) lets you see who is at your door in 2K head-to-toe clarity. The Video Doorbell operates on a built-in rechargeable battery with an option for hardwiring to your existing doorbell wiring. The Video Doorbell can send instant notifications through the Reolink app, and is also compatible with Amazon Alexa and Google Assistant. The package includes a plug-in Doorbell Chime to provide audible alerts inside your home. In addition to the doorbell and chime, a 64 GB microSD card is provided for storing your video footage. The Video Doorbell is covered by a 2-year warranty.
Doorbell Camera: The Wi-Fi Video Doorbell has a wide and high viewing angle with a 1:1 aspect ratio to provide a head-to-toe view at your door. The camera's 1/3.11" CMOS image sensor produces 4 megapixel video with a resolution of 2048 x 2048. The 1.2mm F1.8 fixed lens offers a field of view of 150° Horizontal, 150° Vertical, and 180° Diagonal so you get a full view in front of your door. It has a built-in microphone and speaker to enable clear two-way communication with echo suppression and noise reduction.
Advanced Motion Detection: The Reolink Battery Wi-Fi Video Doorbell can accurately detect and identify people, vehicles, and packages, and provide detailed notifications to your smartphone and Reolink app when motion is detected. The PIR motion detector has a range of approximately 22 feet (7 meters).
Video Storage: The Video Doorbell is equipped with a microSD card slot for storing your video storage locally. A 64 GB microSD card is included, and the doorbell supports cards up to 256 GB. You can also pair the camera with the optional Reolink Home Hub (sold separately by the manufacturer) that supports two microSD cards (up to 512 GB each).
Dual Band Wi-Fi: The Video Doorbell supports 2.4GHz/5GHz dual-band Wi-Fi (802.11a/b/g/n) with its upgraded connectivity and security. The 2.4 GHz band offers long range coverage that reaches far beyond the doorbell placed outside your home, while the 5 GHz band delivers rapid network speeds for fast, effective security.
Mounting: The package includes a bracket and hardware 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 holes using the provided screw hole template. The Video Doorbell is IP65-certified weatherproof, and can operate in extreme temperatures between 14°F and +131°F (-10°C to 55°C).
Power Options: The Reolink Video Doorbell is powered by a built-in 7000 mAh rechargeable battery. A fully charged battery will last approximately 5 months, based on 20 doorbell events per day, and each recording lasting about 8 seconds on average. You can charge the battery with a USB power adapter (minimum 5V 2A output). If you are replacing an existing wired doorbell (8-24V AC wiring), you can connect the doorbell to the existing wiring. The battery remains charged at all times to provide power in case of an outage.
Chime: The included Reolink Chime plugs directly into a nearby electrical outlet and pairs with the Video Doorbell via a 915 MHz wireless frequency. Up to 5 Chimes can be paired with the doorbell camera so you can hear alerts in multiple rooms. You can choose from 10 selectable ringtones or melodies. You can set the volume of the chime in 5 levels: mute (0dB), low, moderate, loud, and very loud (100dB). The LED ring indicator also flashes when the doorbell is pressed or a motion detection alert is received from the video doorbell.
Voice Assistants: The Reolink Battery Video Doorbell can be paired with Amazon Alexa or the Google Assistant so you can hear alerts or see what's happening outside your door at any time. Smart displays, such as the Google Nest Hub or the Amazon Echo Show, can display images from the camera when asked via voice command.
Reolink App: The Reolink App (iOS 13.4+, Android 8.0+) is an easy-to-use mobile app that lets you view live video and recordings from your Reolink video doorbells, cameras, NVRs, or Home Hub. The Reolink App & Client works with your Windows or Mac desktops and laptops (Windows 7 or later, macOS 10.9 or later). You can also access your footage through web browsers, such as Edge, Google Chrome, and Firefox. The app features pre-recorded Quick Replies that can speak for you when someone is at your door.
