Quick Answer
There is no single answer, because two completely different mechanisms are at work. On a cloud platform, retention is a policy: Ring’s US defaults are 60 days for 1080p and 2K cameras and 30 days for 4K, adjustable from 1 to 180 days per device, while Google’s Nest cameras store up to 30 days of event history on the Standard plan or 60 on Advanced. On a local system, retention is arithmetic – drive size divided by how fast your cameras fill it. The one that surprises people: continuous 24/7 recording is held for less time than event clips, not more.
The Answer Depends on Where the Video Lives
“How long does my camera keep footage” gets answered badly because people ask it as if it were a property of the camera. It is not. It is a property of the storage, and the two main storage architectures behave in completely different ways.
Three retention models. Only local storage gives you a number you can change.Cloud storage has a retention window set by the platform and your subscription tier. It does not matter how much footage you generate – a quiet camera and a busy one on the same plan both keep the same number of days. Local storage has no policy at all; footage accumulates until the drive is full, then the oldest is overwritten. A quiet camera on a big drive can hold months; four busy 4K cameras on a small one might hold days.
Cloud Retention Is a Policy, Not a Capacity
Ring publishes its retention behavior in unusual detail, which makes it a useful reference point for the whole category. The US default is 30 days for 4K devices and 60 days for 1080p and 2K devices, and you can set anything from 1 day up to 180 days.
Two details in that arrangement do real work and are easy to miss. The setting is applied per device, so changing it on your doorbell does nothing for the camera over the driveway – each one has to be set individually. And a change applies only to future recordings, so shortening the window and then lengthening it again does not bring back what already aged out.
Ring also describes a state worth knowing about in advance: past events may still appear in your history without being viewable or recoverable. If you have ever seen an event listed and been unable to open it, that is what you are looking at rather than a bug.

Continuous Recording Is Held for Less Time, Not More
This is the finding most likely to change somebody’s purchase, and it runs against intuition. Continuous recording sounds like the premium option, and it produces the shortest-lived footage in these systems.
Ring states that 24/7 Recording footage is stored temporarily in the cloud for up to 14 days, and recommends downloading anything you want to keep beyond that. That is on cameras where event clips may be retained for 60 days by default and up to 180 if you choose. Google’s arrangement is similar in shape: continuous video recording is described as up to 10 days of 24/7 video history, and requires the Advanced plan, against 30 or 60 days of event history.
The reason is straightforward once stated – continuous video is enormously larger than motion clips, so the economics of holding it are different – but nothing about the marketing signals it. If your reason for wanting continuous recording is an incident you might not discover for three weeks, it is the wrong tool, and local storage is the honest answer.
It is also worth knowing what continuous recording costs to enable. Ring requires an eligible camera that is hardwired, plugged in or powered over Ethernet, a Ring Protect subscription, and a separate 24/7 Recording add-on for each camera, capped at 10 devices per location. Our guide to Ring’s subscription plans breaks the tiers down.
Published Retention, Platform by Platform
| Storage type | Event clips | Continuous recording | Set by |
|---|
| Ring cloud | 60 days default for 1080p and 2K, 30 for 4K, 1-180 adjustable | Up to 14 days | Plan policy plus a per-device setting |
| Google Nest cloud | Up to 30 days on Standard, 60 on Advanced | Up to 10 days, Advanced only | Subscription tier |
| Nest, no subscription | Up to 6 hours of event video previews | Not available | The free allowance |
| Local NVR or hard drive | Until the drive fills, then oldest overwritten | Same – continuous is the normal mode | Drive size, camera count, resolution |
| Camera memory card | Until the card fills, then oldest overwritten | Depends on the camera | Card capacity and bitrate |
The row that changes the framing is the third one. Google lists up to 6 hours of event video previews without a subscription on the current Nest Cam – enough to check what happened this morning, not enough to review a weekend. That is the real free-tier retention on a cloud platform, and it is the number worth comparing against a memory card.
Local Storage Is Arithmetic
On a local system there is no retention policy to read. Footage accumulates until the disk is full and then the oldest is overwritten, so “how long” is a calculation with four inputs: drive size, number of cameras, resolution, and whether recording is continuous or motion-triggered.
Reolink’s 8-channel 4K system gives a concrete sense of the scale involved – it ships with a 2TB drive pre-installed, supports capacity up to 16TB, and handles simultaneous live feed and 24/7 recording of all cameras. An eight-fold increase in drive size is an eight-fold increase in retention, which is a lever no cloud plan offers.
What moves the number
1
Drive size
The most direct lever. Reolink’s NVR takes up to 16TB against the 2TB it ships with.
2
Camera count
Four cameras fill a drive roughly four times as fast as one, all else equal.
3
Resolution
4K footage is substantially larger per hour than 1080p. Higher resolution buys detail and costs retention.
4
Continuous or motion-only
Motion-triggered recording can multiply retention several times over, at the risk of missing anything that did not trigger detection.
None of these are set by anybody but you, which is the structural advantage of owning the storage.
The tradeoff is equally structural and worth stating: local footage lives in the building. If the recorder is stolen or destroyed, the evidence goes with it. That is the strongest single argument for cloud storage and no local system answers it – we go through the whole decision in our piece on where footage should live, and our guide to memory cards for security cameras covers the memory-card version of the same question.
If retention is the reason you are considering local storage, the practical entry points are a kit with the recorder built in or a conventional NVR – our guide to camera kits with a built-in monitor covers the all-in-one versions, and our wired system comparison the higher-capability wired route.
What Happens When You Stop Paying
This is the part people discover at the worst moment. On a cloud platform, the subscription is not just paying for new recordings – it is what keeps the existing history accessible.
Ring is explicit that a subscription is required to review recorded video and that events are only recorded after you subscribe. The implication runs both ways: subscribing after an incident does not retroactively capture it, and letting a subscription lapse does not leave you with a read-only archive. A failed card renewal produces a gap in your history that you cannot fill afterwards.
Google’s structure has the same shape with a small free allowance underneath it – up to 6 hours of event previews on the current Nest Cam without a plan. That is enough to notice the subscription lapsed, if you happen to look.
Two failure modes worth guarding against
Cloud
- A lapsed payment silently stops recording entirely
- Cancelling generally ends access to existing history
- Retention is whatever the platform decides next year
- Downloading anything important is on you
Local
- A full drive silently overwrites the oldest footage
- A failed drive takes everything with it
- Theft of the recorder removes the evidence
- Nobody warns you that the retention window has shortened
How Long Do You Actually Need?
Longer is not automatically better, and the honest answer for most households is shorter than the maximum. The useful question is how long it typically takes you to notice something.
A package theft or a damaged car is usually noticed within a day. A break-in, immediately. Those cases are covered comfortably by any of the default windows above, and by almost any local drive. The cases that genuinely need long retention are slower-burning: a boundary dispute, a pattern of minor incidents you only recognize as a pattern after weeks, an insurance claim that surfaces late.
If you are in one of those situations, note that the maximum cloud window is 180 days per device on Ring but only 14 days for continuous recording – so the long-retention answer on a cloud platform is event clips with the window raised, not 24/7 recording. On a local system it is simply a bigger drive. Either way, download anything genuinely important rather than trusting a retention window, which is Ring’s own recommendation for footage you want to keep past the limit.
What to Actually Do
Check your per-device retention setting today, and download anything you already know matters. On Ring that setting is per camera rather than per account, so it is entirely possible for your doorbell to be keeping 60 days while a camera you set up later is on something shorter. It takes a couple of minutes and it is the highest-value thing on this page.
If you need long retention, raise the event-clip window rather than buying continuous recording – Ring allows up to 180 days per device for event clips against a 14-day cap on 24/7 footage, and Google’s continuous option gives 10 days against 30 or 60 for event history. Continuous recording answers “what happened in the gaps between motion events,” not “what happened last month.”
What would change this: if retention is genuinely your primary requirement, a local system is the structurally better answer, because a drive you can enlarge beats a policy you cannot change – Reolink’s NVR taking up to 16TB is a different kind of promise from a plan tier. Accept the tradeoff honestly, though: local footage is in the building, and if the recorder goes, so does everything on it.

Frequently Asked Questions
How long does Ring keep footage?
In the US the default is 60 days for 1080p and 2K cameras and 30 days for 4K, and you can set anything from 1 to 180 days. The setting applies per device rather than to your whole account, so each camera has to be set individually.
How long does Nest keep footage?
Up to 30 days of event history on the Standard plan or 60 days on Advanced, with continuous recording giving up to 10 days of 24/7 history on Advanced only. Without a subscription the current Nest Cam includes up to 6 hours of event video previews.
Why is continuous recording kept for less time than motion clips?
Because continuous video is far larger. Ring caps 24/7 Recording footage at 14 days on cameras whose event clips may be kept for 60 or even 180 days. If you need long retention, continuous recording is the wrong feature to buy.
Can I get footage back after it expires?
No. Cloud retention windows delete permanently, and changing the setting only affects future recordings. Local systems overwrite the oldest footage when the drive fills. Download anything you might need rather than relying on the window.
What happens to my recordings if I cancel my subscription?
On cloud platforms, expect to lose access to the history as well as stop new recordings. Recording only happens while you are subscribed, so a lapsed payment leaves a gap that cannot be filled retroactively.
How long will a 2TB drive record for?
It depends on camera count, resolution and whether recording is continuous or motion-triggered – there is no single answer. The useful point is that it is arithmetic you control: doubling the drive doubles the retention, which no subscription tier lets you do.
Is local storage or cloud storage better for keeping footage longer?
Local, if retention is the priority – a bigger drive is a direct lever and cloud windows are fixed by policy. Cloud is better if survivability matters, because local footage is lost with the recorder if it is stolen or destroyed.
Should I set my retention to the maximum?
There is rarely a reason not to on a cloud plan, since it costs nothing extra. Just do not confuse it with insurance – the setting only affects footage recorded from now on, and anything you genuinely need should be downloaded rather than left in the window.
