Capture video and communicate with visitors at your front door with the DB1 3MP Wi-Fi Smart Doorbell from ezviz. This dual-band Wi-Fi device uses a 1/2.8" starlight sensor to capture 2048 x 1536 resolution video at 30 fps. The 2.2mm fixed lens delivers a 180° vertical field of view for full-body visibility of visitors at your door. The DB1 provides up to 16' of night vision, along with up to 16' of human detection thanks to a PIR sensor. A built-in omnidirectional microphone and loudspeaker enable two-way audio communication. This device replaces a wired doorbell and uses the existing doorbell wiring. It has a built-in memory card slot that accepts microSD cards up to 128GB (available separately). Remote viewing, real-time talk, and instant alerts are possible via the EZVIZ app for iOS and Android. The DB1 has an IP65-rated enclosure for protection against dust and water.
