How Long Do Security Cameras Keep Footage Before it is Deleted? It’s a question many homeowners and business owners ask after an incident has already happened—or when they're considering installing a system for the first time. Understanding the lifespan of recorded footage is critical, especially when it comes to safety, legal issues, or simply gaining peace of mind.
At Cam Security Surveillance LLC, we’ve helped hundreds of clients across residential and commercial spaces build custom surveillance systems. One of the most frequent concerns we address is: “How far back can I access my security camera footage?” In this post, we’ll walk you through what determines retention time, how footage is deleted, and what you can do to ensure important recordings aren’t lost too soon.
What Determines How Far Security Camera Footage Goes Back?
1. Storage Capacity
The primary factor that affects how long security cameras store footage is the amount of storage available on the system whether that’s an SD card, hard drive (DVR/NVR), or cloud-based service. Once the storage reaches capacity, older footage gets deleted or overwritten.
2. Recording Method
There are two main types of recording:
Continuous recording: Cameras record 24/7, filling up storage space quickly.
Motion-triggered recording: Records only when motion is detected, allowing for longer retention periods.
3. Resolution and Frame Rate
Higher video resolution (e.g., 4K vs. 720p) consumes more storage space. Likewise, higher frame rates (e.g., 60fps vs. 30fps) shorten the amount of time footage can be saved before deletion.
4. System Configuration
Your system’s software or settings will define the exact period video footage is stored before deletion this could range from a few days to several months.
How Long Do CCTV Cameras Record?
If you're wondering how long do CCTV cameras record, the answer varies based on the system setup. Traditional CCTV systems with DVRs usually retain footage for:
7 to 30 days for home or small business use
30 to 90+ days for commercial or legal compliance needs
However, motion detection and smart compression technology can significantly extend this period. At Cam Security Surveillance LLC, we often recommend optimized systems that strike a balance between high-quality recording and efficient storage usage.
Do Security Cameras Delete Footage Automatically?
Yes, most modern systems are programmed to automatically delete or overwrite footage when storage runs out. This function often called loop recording ensures continuous operation.
Here’s how it typically works:
Once the storage device is full, the oldest video files are overwritten with new footage.
Some systems allow you to configure retention settings, enabling you to choose whether footage is kept for a certain number of days or until manually deleted.
For clients looking for Home Security Camera Installation, we always advise reviewing these settings right after installation to prevent accidental data loss.
How Long Is Security Camera Footage Kept?
So, how long is security camera footage kept? Here’s a general idea based on the type of system:
Cloud-based systems (Ring, Nest, etc.): 7 to 30 days (or more with upgraded plans)
DVR/NVR systems: 10 to 90+ days depending on storage capacity and resolution
SD card systems: Usually hold 3 to 10 days of footage
Business-grade systems: Can retain footage for up to a year if required
The key takeaway? Retention time is highly flexible—but only if you know how to configure your system properly. That’s where a trusted name like Cam Security Surveillance LLC comes in. We ensure your camera system matches your needs and expectations, whether you're monitoring your home or managing a commercial property.
How to Extend the Length of Time Footage Is Stored
If you want your security footage to go back further than your current system allows, consider the following tips:
Upgrade Your Storage Capacity:
Choose a DVR/NVR with more terabytes.
Add external storage options if your system allows.
Use Smart Recording:
Switch to motion-detection or scheduled recording modes.
Reduce resolution or frame rate (only if quality is not a top priority).
Back Up to the Cloud:
Combine local storage with a cloud plan for long-term archival.
Cloud footage is usually safer from physical theft or damage.

FAQs
Can I access old footage from my camera system?
That depends on how long your system retains footage. If the footage hasn’t been overwritten or deleted, and you have the right storage capacity, you should be able to access it.
What happens when the storage on my security camera is full?
In most cases, the system automatically deletes the oldest footage to make room for new recordings—unless you’ve backed it up or changed the default settings.
Is it possible to save footage permanently?
Yes. Most systems allow you to manually export important clips to external drives or cloud storage for long-term retention. This is a common recommendation we make during Home Security Camera Installation projects.
