On this product
IR Night Vision
Black-and-white visibility without visible light, ideal for discreet overnight monitoring.
Dual Light
Uses IR normally, then activates a spotlight for full-color detail when it matters.
Color Night Vision
Retains useful color from ambient light without requiring a visible spotlight.
Ultra Color Night Vision
Advanced low-light processing preserves the clearest color and background detail in very dark scenes.
The examples explain relative viewing modes. Actual brightness, color, and range depend on the camera, placement, and available ambient light.
Night Viewing Range
Centered distance markers show how far this doorbell is rated to view from the porch.
"Up to" is the manufacturer-listed maximum viewing or illumination distance. Recognizable detail may be shorter and varies with lighting, night-vision mode, weather, placement, lens settings, and obstructions.
Description
The Alarm.com ADC-VDB781B Battery Doorbell Camera brings intelligent front-door video to entrances where existing doorbell wiring is unavailable or inconvenient. Its replaceable 6,450 mAh battery supports multi-month operation, charges by USB-C in approximately five hours and can also use compatible doorbell terminals for ongoing charging and chime support.
A 2.4MP color sensor records a square 1536 x 1536 image with a 148-degree horizontal and vertical field of view, helping show both visitors and packages near the doorstep. Infrared illumination reaches approximately 15 feet after dark, while the IP54 enclosure is designed for outdoor operation from -4 to 113 degrees Fahrenheit.
With a compatible Alarm.com video service plan, Video Analytics can distinguish people, vehicles and packages and can provide familiar-face alerts. Perimeter Guard can play an audible warning when selected activity is detected, and two-way talk lets users speak with visitors through the Alarm.com app from home or away.
Dual-band 2.4 and 5 GHz Wi-Fi 5 provides flexible network placement, while Bluetooth 5.4 supports local setup. The camera does not require a separate video hub. A wall plate, mounting hardware, wall spacers and a 5-degree tilt wedge are included to help frame the entry correctly.
