Wire-free and worry-free front door protection
It's the new go-to video doorbell for any apartment dweller or villa owner. The EZVIZ DB2-B Pro features ultra-sharp 2K⁺ resolution, wide field-of-view, large battery capacity, and extremely easy installation. Users can enjoy an extra-layer of privacy protection using the voice changer feature, and set up no-filming privacy zones.
Clear, vivid view with EZVIZ’s 2K⁺ video doorbell
Featuring the top resolution of its kind, the DB2-B Pro renders crisp, clear video to capture every vivid detail of the visitors, and provides 5-meter infrared night vision for 24/7 protection.
A well-thought-out solution in one kit
To make sure you hear the ring even from afar, EZVIZ pairs it with an indoor chime. What’s better, the chime can help extend your Wi-Fi signal, and boost the network for the doorbell to ensure it get connected stably – which many wireless doorbells may struggle with.
Set up in minutes, and use for about 4 months
If you are less than a stellar electrician, this wireless, wire-free and weatherproof DB2-B Pro could be your best option – stick it anywhere and enjoy long-lasting performance.
See ultra-wide to get the whole picture
With a 176-degree viewing angle, you can easily see the postman from head to toe and know where he places your package. The doorbell also comes with several different mounting plates in the package, which can help adjust the angle of installation to optimize the doorbell’s vision.
A smart doorkeeper to keep you in the know
With both human-shape and PIR detection capabilities, the device is smart enough to distinguish people from pets or objects. You can customize the alert trigger conditions³ to adjust its sensibility.
Talk, before you get the door
Respond to friends or deliveries with only a simple tap. If you live alone and prefer to stay unidentified to a stranger, just use the voice changer for extra peace-of-mind.
Easy to use but hard to tamper with
In case the doorbell is forcibly removed, a sharp alarm will sound and a mobile alert will be instantly sent to you. What’s more, the DB2-B Pro prohibits unauthorized use after theft, thanks to the account binding restriction.
Enhanced viewing pleasure with smaller video files
Compared to the prevailing H.264 video compression technology, H.265 creates a more fluid viewing experience with recorded videos. Meanwhile, you won’t have to worry about large video files taking up too much of your storage space – H.265 technology reduces their sizes by up to 50%⁴.
Safe, flexible storage options
You can insert a microSD card onto the indoor chime to save your recordings locally, without worrying about any data loss even if the doorbell is damaged or lost. You can also subscribe to EZVIZ CloudPlay for unlimited storage space and an additional layer of data protection.
One app for everyday, everything
EZVIZ App will always connect you to your home, even if you are far away from it.
