Video Doorbell vs Intercom
The difference between a video doorbell and an intercom is that a video doorbell provides both audio and video communication with the visitor, while an intercom only allows audio communication. Video doorbells are used in buildings, apartments, and houses to provide security and to check the visitor, and grant access to unlock the door. The intercom allows only speech conversation between two parties on either side of the intercom.
A video doorbell is a device that is used in the security system of houses, apartments, offices, and other buildings and provides a view of the outside of the house where the device with the camera is placed. You can check who is visiting you through the monitor on your end and can also grant or deny access to the person in your house.
An intercom (also known as an intercommunication device) is used for communication between two parties, each on one side of the intercommunication device. It is used in offices, buildings, apartments, hotels, and also in vehicles. It can also be connected to walky-talky, public communication systems, or computers.
