The EZVIZ DP2C combines a smart doorbell and a surveillance camera with an indoor screen for your home's comfort and security. It installs in place of the traditional peephole and gives you a wide 155° viewing angle and a 1080p Full HD ultra-clear lens, enabling you to clearly see visitors at your front door anytime. A 4.3-inch color screen inside the house displays the image instantly when the doorbell is pressed. You can also receive alerts and converse via your smartphone using the EZVIZ app. The device operates on a rechargeable 4600 mAh lithium battery for long operating hours and features clear night vision up to approx. 3m. It supports storage on a microSD card up to 512 GB or in the cloud. The device's design is suitable for doors with a thickness/peephole range between 15.5 to 50 mm and for doors with a diameter between 35 to 105 mm. It provides advanced security, easier control, and a smart experience for daily use. Why choose EZVIZ HP4?
