Most security cameras keep footage for 7 to 90 days, depending on your setup. Home systems typically keep recordings for 7 to 30 days. Businesses usually hold onto video for 14 to 90 days. High-security locations like banks or government buildings can store footage for 6 months to a full year.
That said, the exact length depends on a few key factors — like how much storage you have, your camera’s resolution, and whether you’re using a cloud plan or a local hard drive.
Key Takeaways:
- Home systems usually keep footage for 7 to 30 days
- Small businesses typically store video for 14 to 90 days
- High-security sites (banks, warehouses, government buildings) often keep footage for 90 days to 1 year
- Storage space, video quality, and recording settings all affect how long your footage lasts
- Cloud storage retention depends on your subscription plan
- Local storage (DVR/NVR) auto-deletes old footage once the drive is full
- 30 days is the sweet spot for most homeowners
How Long Do Most Security Cameras Actually Store Video?
The average security camera doesn’t keep footage forever — and that’s by design. Old recordings get replaced by new ones once storage fills up. This process is called overwriting, and it’s the most common way footage gets deleted.
Here’s a quick breakdown of typical retention periods by setting:
| Setting | Typical Retention |
|---|---|
| Home security | 7 – 30 days |
| Small business | 14 – 90 days |
| Retail / commercial | 30 – 90 days |
| High-security (banks, hospitals) | 90 days – 1 year |
| Cloud (basic plan) | 7 – 30 days |
| Cloud (premium plan) | 30 – 90+ days |
If you’re setting up home security cameras for the first time, a 30-day retention window is a solid target. It gives you plenty of time to catch a missed delivery, resolve a dispute with a neighbor, or review an incident on your property.
What Affects How Long Footage Is Stored?
Several things control how many days of video your system can actually hold. Understanding these factors helps you get the most out of your setup.
Storage Capacity
More storage = more footage. A basic 1TB hard drive holds far less than a 4TB or 8TB drive. Systems with larger DVR or NVR drives can store weeks more video than smaller ones.
Video Resolution
Higher resolution means bigger file sizes. A 4K camera eats up storage much faster than a 1080p or 720p camera. If long-term storage matters to you, lower resolution cameras — or mixed setups — can be a smart tradeoff.
Frame Rate
More frames per second (FPS) means smoother video — but also larger files. Cameras set to 30 FPS generate more data than those set to 15 FPS or lower.
Number of Cameras
The more cameras you have, the faster your storage fills up. A 4-camera system uses storage four times as fast as a single-camera setup (all else being equal).
Recording Mode
- Continuous recording captures everything 24/7 — uses the most storage
- Motion-triggered recording only saves video when movement is detected — stretches your storage significantly longer
Most modern home security systems use motion detection by default, which is why many homeowners can hold onto 30 days of footage even with modest hard drives.
Local Storage vs. Cloud Storage: What’s the Difference?
How your footage is stored makes a big difference in how long it sticks around.
Local Storage (DVR/NVR)
Local storage systems record directly onto a hard drive in a DVR (Digital Video Recorder) or NVR (Network Video Recorder). Once the drive gets full, the system automatically overwrites the oldest footage with new recordings. There are no ongoing fees, but if the drive fails or gets stolen, the footage is gone.
- No monthly subscription
- Footage is stored on-site
- Old video is automatically overwritten
- Consider a professional installation for optimal setup
Cloud Storage
Cloud-based security cameras upload footage to remote servers. How long it stays there depends on your subscription plan:
| Plan Tier | Typical Retention |
|---|---|
| Free / basic | 3 – 7 days |
| Standard | 14 – 30 days |
| Premium | 30 – 90 days |
| Enterprise | 90 days or more |
Cloud storage gives you remote access from anywhere, and footage isn’t lost if hardware is damaged or stolen. The tradeoff? Ongoing monthly costs and data privacy considerations.
How Long Should You Keep Security Camera Footage?
For most homeowners, 30 days is the sweet spot. Here’s why:
- Package deliveries typically show up within a few days
- Disputes or incidents usually get reported within 1 to 2 weeks
- Insurance claims often need to be filed within 30 days of an incident
Businesses may need to hold onto footage longer. Retail stores, for example, often review video weeks after a shoplifting incident is first noticed. Financial institutions and healthcare facilities typically follow strict regulatory requirements — often 90 days or more.
If you’re not sure your current system is keeping up, it may be worth looking into a security system upgrade to expand your storage or add cloud backup.
Does Old Footage Get Deleted Automatically?
Yes — in most cases, it does. Here’s how that usually works:
- Local DVR/NVR systems: Once the hard drive hits capacity, the system loops back and records over the oldest footage. No manual action needed.
- Cloud systems: Footage older than your plan’s retention window is automatically deleted from the server.
- SD card cameras: Same loop-and-overwrite behavior as local systems.
If you need to save footage permanently, most systems let you manually export clips to a USB drive, external hard drive, or cloud folder before they get overwritten.
If your system isn’t recording correctly or footage seems to disappear faster than expected, it may be time for a security camera repair or checkup.
Additional Details Worth Knowing
- Some states and countries have legal requirements for how long businesses must retain surveillance footage. For example, casinos in many U.S. states are required to keep footage for a minimum of 30 to 90 days.
- HIPAA-regulated facilities (hospitals, clinics) often require 90 days or more of security camera footage.
- Cameras connected to 24/7 alarm monitoring services may have their own footage retention rules tied to the monitoring plan.
- Some newer AI-powered cameras only save “events” (motion clips, faces, packages) rather than full continuous footage — which can dramatically extend effective storage life.
- Deleting footage you’re legally required to keep can create serious liability issues for businesses.
FAQs About Security Camera Footage
How long do home security cameras keep footage?
Most home security cameras store footage for 7 to 30 days. Systems with larger hard drives or cloud plans may keep recordings for longer. Motion-triggered recording helps stretch storage life significantly.
Do security cameras record all the time?
Not always. Many cameras offer both continuous recording and motion-triggered recording. Motion-only mode uses far less storage and can extend your footage retention window by weeks.
What happens when security camera storage is full?
On local DVR/NVR systems, the oldest footage is automatically overwritten when storage fills up. Cloud systems delete recordings past your subscription’s retention window. Either way, old footage disappears to make room for new video.
Can you recover deleted security camera footage?
In most cases, no — once overwritten, local footage is gone for good. Some data recovery tools can help in certain situations, but results aren’t guaranteed. The best approach is to export important clips before they’re overwritten.
How long do businesses need to keep security footage?
It depends on the industry and location. Most small businesses keep footage for 30 to 90 days. Banks, hospitals, and government buildings often keep recordings for 6 months to a year. Some industries have specific legal requirements that vary by state or country.
Bottom Line: Know How Long Your Cameras Are Saving Footage
Security camera retention isn’t one-size-fits-all. Your home system might hold 10 days of footage, while a business across town keeps 90. What matters is that your setup fits your actual needs — whether that’s catching porch pirates, protecting a retail store, or meeting regulatory requirements.
The good news? Getting the right retention length isn’t complicated. It usually comes down to the right storage size, a smart recording mode, and — for businesses — possibly a cloud backup plan.
