Can you get footage back after it has been overwritten?

No. Both loop recording and cloud retention are hard deletions, not archives, and no consumer camera brand keeps a hidden copy past the stated window. This is why the practical rule is to download anything that matters the same day you notice it. Most apps have a download or save-to-phone button on the clip; use it before you call anyone, because the clock on the retention window is already running and it does not pause because there is an incident.

How long do police need footage kept?

Long enough to matter, and longer than most default settings allow. Investigations frequently move on a scale of weeks, while a 14-day cloud plan or a small microSD card can overwrite an incident before anyone reviews it. If you are in a neighborhood with a live issue, the two useful moves are to raise retention to at least 30 days and to export clips locally on a schedule. Requirements vary by jurisdiction and by case, so ask the responding officer what they need rather than assuming.

Does higher resolution shorten how long a card holds?

Substantially. Storage is consumed by bitrate, and bitrate roughly tracks resolution and motion in the scene. At the same compression, 2K uses about twice the space of 1080p and 4K about four times, so a card that holds a week of 1080p might hold under two days of 4K. Cameras using H.265 rather than H.264 roughly halve the file size for the same picture, which is the single biggest lever on how many days a card covers.

Is local storage or cloud storage better for retention?

Local storage usually wins on duration and cost, cloud wins on survivability. A 256 GB card or a hard drive in a network video recorder can hold weeks with no monthly fee, but it is in the building — a stolen camera takes its own evidence with it. Cloud footage survives the camera being ripped off the wall but stops the day you stop paying. Households that care about this run both, with a card in the camera and an event-clip plan on top.

Do cameras record when the internet is out?

Cameras with a microSD slot or a local recorder generally keep recording through an outage, because the card is written directly by the camera. Cloud-only cameras do not: with no upload path there is nowhere for the clip to go, and the event is lost. That difference is the strongest argument for choosing a camera with local storage even if you also pay for a cloud plan. We go through the offline behavior in detail in our guide to cameras without Wi-Fi.

Home security cameras typically retain footage for 14 to 180 days on a cloud plan, or roughly 5 to 7 days of continuous 1080p recording on a 128 GB microSD card. Two different limits are at work. Cloud retention is a fixed window set by your subscription tier, after which clips are deleted permanently. Local storage is a loop: the camera overwrites the oldest file when the card fills, so the duration depends on card size, resolution, compression and whether the camera records continuously or only on events. Free tiers are the shortest, often 3 days or none at all.

How long does each cloud plan keep clips?

Retention is set by the plan, not the camera, and the spread across brands is wide. Figures below reflect published US consumer plans as of 2026 — confirm the current terms before buying, because these tiers change and regional plans differ.

Approach	Typical retention	What is stored	Ongoing cost
Budget cloud tier	14 days	Motion and person events only	Low monthly
Mainstream cloud tier	30 days	Event clips, some with AI sorting	Low to mid monthly
Premium cloud tier	60 days events, around 10 days continuous	Events plus a rolling 24/7 buffer	Mid to high monthly
Long-retention tier	Up to 180 days	Event clips	Mid monthly
Free tier, where offered	3 days or live view only	Thumbnails or short clips	None
Local microSD	Until the card loops	Whatever the camera writes	None
Network video recorder	2 weeks to 3 months	Continuous, all channels	None after hardware

How many days fit on a memory card?

Storage is consumed at a fairly predictable rate, so this is arithmetic rather than guesswork. A 1080p stream using H.265 compression runs roughly 1 GB per hour of continuous recording; H.264 is about double that; 2K roughly doubles again and 4K roughly doubles once more. Event-only recording changes the picture completely, because a camera on a quiet side yard may write only a few minutes an hour.

64 GB, 1080p continuous — about 2 to 3 days.
128 GB, 1080p continuous — about 5 to 7 days.
256 GB, 1080p continuous — about 10 to 14 days.
128 GB, 2K continuous — about 2 to 3 days.
128 GB, event-only recording on a moderate-traffic door — commonly 4 to 8 weeks.

Use a card rated for continuous surveillance write cycles. Standard cards are built for occasional photo bursts, and owners consistently report failures within a year when a general-purpose card is left looping day and night in a camera.

How do you keep a clip past the window?

Download it the day you find it. Every retention limit is a deletion, not an archive, and no brand keeps a private copy for you after the window closes. In practice that means opening the clip in the app, using the save or share button to write it to your phone, and moving it somewhere permanent.

Two habits make the difference. First, raise retention before you need it rather than after, because the upgrade does not resurrect clips already deleted. Second, if the camera has a microSD slot, use it alongside the cloud plan — the card keeps recording when your internet drops, which is exactly when a cloud-only camera records nothing at all. Cameras with usable local storage are flagged in our home security camera picks, and the subscription-free options are set out in using a camera without a subscription.

One more variable that quietly shortens retention: cameras set to record continuously rather than on events fill a card many times faster. Whether that trade is worth it is covered in do home security cameras record all the time.
