This wired WiFi doorbell supports both the 2.4 GHz and 5 GHz WiFi bands to ensure a more stable connection. Simply place it anywhere within WiFi range. You can also connect it to your existing doorbell wiring. A 15° wedge is included to help you adjust the angle. The doorbell will only alert you when a person is detected, ignoring insignificant, non-human passersby. You can also set a motion zone to darken areas that are prone to unnecessary alerts. The infrared LEDs enable high-quality night recordings, so you can see who is there, even in the dark. The Reolink Video Doorbell WiFi features built-in microphones and a speaker. The doorbell camera starts recording before the actual detection occurs. Six seconds of color video footage before the alarm can greatly assist you in understanding potential causes or increasing the likelihood of criminal identification. Flexible storage options: You can store your recordings locally on a microSD card (up to 256 GB) or on a Reolink NVR. If you're concerned about losing the storage media, you can also save events in the Reolink Cloud. Package includes: 1x Video Doorbell D340W, 1x Chime, 1x Mounting Plate, 1x Wedge, 1x Template for Mounting Holes, 1x 1.5 Meter Power Adapter, 1x 1 Meter Network Cable, 1x 4.5 Meter/10 Meter Extension Cable, 1x Bridge Cable, 1x Pack of Screws, 1x Quick Start Guide.
