Tests in this review note that live video from the Nest battery doorbell closely follows real time movement while some competitors like Arlo show several seconds of delay, giving owners quicker awareness when someone approaches or rings the bell.
Compared with other video doorbells, the G4 is frequently praised for extremely low latency, with the time from button press to live video and two way talk among the fastest many testers have experienced.
Testing shows that the Ring Video Doorbell Wired reacts almost instantly when the button is pressed and sends alerts without noticeable delay, indicating minimal lag between activity at the door and notifications or chimes on connected devices.
Reviewers report that live view and doorbell-press connections on the Pro 2 generally load quickly in the Ring app, with minimal lag between a notification and seeing or speaking to the visitor.
Live view loads quickly over 2.4GHz Wi Fi and motion triggered recordings usually start a second or two earlier than older Ring models, reducing the chance of missing someone approaching the door.
Live view performance is generally praised for having minimal lag and quick connection times, making real-time viewing responsive despite other software issues.
Long term feedback suggests live view and audio connect within a few seconds but with noticeable delay compared with wired systems, and this review similarly experienced roughly two second delays from a press to notification, keeping latency present but relatively low for a battery operated doorbell.
