How do Wireless Doorbells Work?

Wireless doorbells integrate with your existing doorbell system and smart home technologies to detect and record activity at your doorstep. Typically installed at the front door or any desired entry point, these devices connect via Bluetooth or Wi-Fi to a central hub or smartphone for real-time monitoring.

Modern wireless video doorbells are accessible and cost-effective, making them a popular choice for homeowners. Unlike traditional doorbells, they don’t require an indoor chime box to alert you.

Do Doorbell Cameras Record All the Time?

Doorbells are always on, but they only record when they detect movement or audio. When the camera captures footage, it often includes a few seconds before and after the event that prompted recording to start for context. For example, if a car parks in the driveway, the camera will also capture footage of the car approaching, allowing it to determine which direction the car came from.

This means the camera is always on and working. Users can access a live stream from their connected mobile apps, and some apps even allow users to manually control recording. Recorded footage is transferred to secure cloud storage.

How Long Do Doorbell Cameras Keep Footage?

This timeline varies depending on user preferences, as well as the manufacturer. Often, cameras themselves don’t save footage, and it is instead kept in cloud storage for anywhere from 10 to 90 days.
