This 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 can alert you when a person is detected while 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 know who is there, even in the dark. The Reolink Video Doorbell WiFi features built-in microphones and a speaker. Take your time to greet the visitor before rushing to the door, deter unwanted visitors without delay, or speak live with visiting friends when you are not home. The doorbell camera starts recording before the actual detection occurs. Six seconds of color video footage before the alarm can help you understand potential causes or increase 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 are concerned about losing the storage media, you can also save events to Reolink Cloud.
