With the Blink security doorbell you can answer your front door from anywhere - and put an end to those 'sorry, we missed you' delivery notes. You'll get pinged on your phone when it detects motion or someone rings the bell, and you can tell the driver exactly where to leave your parcel thanks to 2-way talk. You get clear Full HD video, day or night, so you can check the ID of anyone who turns up unannounced. Good to know - You can get alerts and video on your Alexa devices with the Sync Module (sold separately) - Save and share clips in the cloud with a Blink Subscription Plan or locally with the Sync Module 2 and a USB drive (both sold separately) - Connect it to your existing doorbell wiring to use your current chime __________ Please note: - Stand-alone Blink Video Doorbell does not include Sync Module 2. Without a Sync Module, live view and two-way audio are available only in response to a doorbell press or motion event. With a Sync Module or Sync Module 2 get these features any time on demand. - Blink Subscription Plan will require a subscription.
