How Long Do Security Cameras Keep Footage?
Imagine needing footage of a break-in—only to find it was deleted yesterday
Security cameras help protect homes and businesses, but their footage doesn’t last forever. How long videos stay saved depends on your system’s storage type, settings, and legal requirements. This guide explains what affects retention time and how to keep important footage longer.
What Affects How Long Footage Is Stored?
Several factors determine how long your security camera recordings last:
- Storage Type: SD cards hold footage for days, while hard drives and cloud storage can keep videos for weeks or months.
- Recording Mode: Continuous recording fills storage faster than motion-activated recording.
- Video Quality: High-resolution (4K) videos take up more space than lower-quality footage.
- Storage Capacity: Larger hard drives or cloud plans store more video before deleting old clips.
- Overwrite Settings: Most systems automatically erase old footage unless you manually save it.
How Long Does Footage Last on Different Systems?
Retention times vary based on your camera setup:
- SD Cards (used in doorbells and small cameras) – 1 to 7 days before looping.

For example, a 2TB hard drive with four 1080p cameras recording motion-only can store about 30 days of footage.
How to Keep Security Footage Longer
If you need to extend your camera’s retention time, try these tips:
- Increase Storage – Upgrade to a larger hard drive or expand cloud storage.
- Use Motion Recording – Saves space by only recording when movement is detected.
- Lower Video Quality – Reduces file size if ultra-HD isn’t necessary.
- Back Up Important Clips – Export key footage to an external drive or cloud.
- Check Legal Rules – Some businesses must keep footage for 30+ days.
By adjusting these settings, you can ensure important videos stay available when needed.
Security camera footage retention depends on your system’s setup. To avoid losing critical recordings, review your storage settings and upgrade if needed. Whether for home safety or business security, managing your camera’s storage properly ensures you always have the footage when it matters most.
How Wireless and Wired Security Cameras Store Footage

About How Security Cameras Store Footage
Where exactly does my security camera save the recordings?
Most security cameras store footage in one of two main ways. Wireless cameras typically upload videos to cloud storage through your Wi-Fi network, where they’re kept on secure servers you can access from your phone. Wired systems usually save everything directly to a physical hard drive in a DVR/NVR box, which gives you complete control but requires you to be on-site to access older footage. Some newer models offer both options as a backup.
How long will my camera keep videos before they disappear?
The duration your footage stays available depends on several factors. If you’re using cloud storage, most providers keep videos for 7-30 days unless you pay for extended storage. Local storage on hard drives can last months depending on the size – a 2TB drive might store about a month of continuous HD footage from four cameras. Motion-activated recording stretches this out significantly compared to 24/7 recording. Many systems automatically delete the oldest files when space runs out.
Do I absolutely need internet for my cameras to save footage?
Not necessarily. Traditional wired systems will keep recording to their hard drives without any internet connection at all. Wireless cameras are trickier – most need Wi-Fi to upload to cloud storage, but models with SD card slots can still save footage locally without internet. Just remember you won’t get alerts or remote access when offline.
Are those monthly cloud storage fees unavoidable?
They’re common but not mandatory. Many reputable brands offer free basic cloud plans with limited storage (usually a few days of clips). For serious security needs, paid plans provide longer retention and more features. The alternative is self-contained systems using local storage, which have higher upfront costs but no recurring fees. It’s really about choosing what works for your budget and needs.
What happens if I accidentally delete important footage?
Unfortunately, recovery options are limited. Cloud services sometimes have brief grace periods where deleted files can be restored, but local storage typically erases permanently when space is needed. Your best bet is to immediately download and backup any crucial footage to another device. Some advanced systems have protected folders where important clips won’t auto-delete.
Which storage method gives me the most reliable protection?
Each has strengths. Cloud storage protects against theft or damage to your equipment since footage exists off-site, but depends on your internet connection. Local storage gives you complete physical control and avoids monthly fees, but risks losing everything if the hardware fails or is stolen. Many security experts recommend a hybrid approach – using local storage as your primary with cloud backup for the most critical footage.
