The EZVIZ DP2 combines functions of a traditional door spy, IP camera and doorbell system into a single smart device. It offers a 4.3-inch LCD touch screen and a 166-degree HD wide-angle lens, so you have a clear view of who is at the door. The PIR motion alerts for human movement detection will immediately send alarm notifications to your smartphone with a photo via EZVIZ app when detecting potential intruders. The two-way audio function allows you to communicate with visitors via the EZVIZ app. The 5-meter IR distance for night vision allows users to see and record videos even when it's dark outside. EZVIZ DP2 is equipped with a 4600mAh low power consumption, long service life and rechargeable lithium battery.
