Product Description:
eufy Security Video Doorbell Dual Camera (Battery Powered) provides a much-needed second camera to the system to provide you the full story instead of having blindspots in your security recordings. It also stores every moment locally on HomeBase inside your home behind military-grade AES128 data encryption. It ensures your footage is kept private on transmission and storage. If someone were to forcibly remove the doorbell, all your data will remain secure.

• Dual-motion detection
  The advanced PIR and radar motion sensors are able to distinguish both near and far subjects and reduce 95% of false alarms.
• Delivery Guard
  Get instantly notified when your package arrives with Delivery Guard. Plus, you'll receive pick-up reminders and alerts if someone approaches your package.
• Family recognition
  Video Doorbell Dual recognizes your loved ones and can be programmed to only alert you when you get visitors you don’t know.
• 2K with HDR
  Quad HD surveillance ensures visitors can be identified from the smallest details. And thanks to high dynamic range, visitors who are backlit by the sun can be seen in perfect color and clarity.
• No monthly fee
  Designed to protect your home as well as your wallet, eufy Security products are one-time purchases that combine security with convenience. All your data is stored locally meaning you will never have to pay for cloud storage.
• Works with voice assistant
