*Video Door Phone: A video door phone is a security and communication system that allows you to see and talk to visitors at your entrance from a monitor inside your home or a smartphone, even when you're away. It consists of an outdoor unit with a camera and speaker to capture visitors and an indoor unit with a display and microphone for the resident to communicate and potentially grant access. These systems offer enhanced home security by providing visual confirmation of visitors and enabling remote interaction, functioning like a video calling doorbell.
*Electronic Door Lock: An electronic lock is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock.
