Can a video doorbell record 24/7?

A few wired models offer a continuous mode, usually on a premium subscription tier or to a local recorder, but it is uncommon and it is never available on battery power. The reason is straightforward: continuous recording requires the image sensor, encoder and radio to stay awake, which turns months of battery runtime into hours. If you genuinely need continuous coverage of the front of the house, the practical arrangement is a wired camera nearby doing that job while the doorbell handles the door.

What is pre-roll and do I need it?

Pre-roll is a short buffer, usually three to six seconds, that the doorbell keeps in memory so the saved clip starts before the trigger fired. It matters because without it the first frames of a clip often show someone already at the door rather than approaching it. Wired doorbells manage it easily since they have power to spare; some battery models offer a low-resolution version at a cost to runtime. It is one of the more genuinely useful features on the spec sheet.

Does the doorbell record when someone just walks past?

Only if a motion zone covers the sidewalk, and you almost certainly do not want it to. Doorbells sited near a street or a shared path generate constant alerts unless the zones are trimmed back to the walkway and the porch. Most apps let you draw exclusion areas and set a sensitivity level, and person-only detection filters out cars and animals. Spending ten minutes on zones is the difference between useful notifications and an app you mute.

Is my doorbell recording audio too?

Yes, on essentially all models, and this is where the law differs by state. Some US states require the consent of all parties to record a conversation, and a doorbell capturing audio from a porch or sidewalk can raise questions that video alone does not. Most apps allow audio recording to be turned off. If your doorbell overlooks a shared hallway, a neighbor door or a public path, check your state rules and consider disabling audio.

Do doorbells stop recording when the internet goes down?

Cloud-only doorbells do, because there is nowhere to send the clip. Models with a microSD slot or a local hub keep recording to that storage and sync later, which is the strongest argument for choosing one with local storage even if you also pay for a plan. The chime and the button still work regardless if the doorbell is wired to an existing transformer, since that circuit is independent of your network.

No. Video doorbells record in short clips triggered by motion or a button press, typically 10 to 60 seconds each, rather than continuously. Battery-powered doorbells cannot record around the clock at all — the sensor sleeps between events to preserve runtime, and keeping it awake would reduce months of battery life to hours. A handful of hardwired models offer continuous recording on a premium plan or to local storage, but it is the exception. What the doorbell does maintain at all times is live view on demand, which you can open from the app whether or not anything is being recorded.

What actually triggers a recording?

Three things, and understanding which one fired explains most of the missed clips people complain about.

The button. Always recorded, always reliable, and the one event that never depends on detection settings.
Passive infrared motion sensing. A heat sensor watching for a warm body crossing its field. It uses almost no power, which is what makes battery doorbells possible, but it misses subjects moving straight toward the lens and struggles when the ambient temperature approaches body temperature on hot afternoons.
Video motion analysis with person detection. The camera compares frames and classifies what changed. More sensitive and much better at catching approaches, but it needs the sensor awake — so it is generally a wired-doorbell capability, and person filtering is usually the paid tier.

If your doorbell keeps missing people, the cause is usually zones and sensitivity rather than the hardware. Trim the motion zone to the walkway and the porch, raise sensitivity, and check that nothing warm and moving sits inside the zone all day.

How do wired and battery doorbells compare on recording?

Power is the whole story. A doorbell on an existing transformer can afford to keep its sensor running; one on a rechargeable pack cannot.

Capability	Battery doorbell	Hardwired doorbell
Event clip recording	Yes	Yes
Pre-roll before the trigger	Sometimes, low resolution, costs runtime	Yes, full quality
Continuous 24/7 recording	No	On some models and tiers
Video motion detection	Rarely	Yes
Snapshot capture between events	Occasionally	Yes
Wake-up delay	1–3 seconds	Near instant
Recording during an internet outage	Only with local storage	Only with local storage

That wake-up delay is the practical difference people notice most: a battery doorbell often shows the visitor already at the door, while a wired one with pre-roll shows them walking up the path. If you have existing doorbell wiring, use it — the installation is covered in how to install a video doorbell, and the trade-offs in full are in wired vs wireless video doorbell.

Where do the clips go, and for how long?

To a cloud plan, to a microSD card or local hub, or both. Cloud retention on consumer plans runs from around 14 days at the budget end to 180 days on long-retention tiers, and free tiers are typically 3 days or live view only. Local storage loops instead, overwriting the oldest clip when the card fills — a card in a doorbell recording events on a moderately busy street commonly covers several weeks. The full figures and the arithmetic are in how long security cameras store footage.

The important habit either way: download anything that matters the same day. Retention windows are deletions, not archives.
