How Long Do Security Cameras Keep Footage: Key Factors

When it comes to video surveillance, understanding what controls how long your footage is retained is vital. Limited storage capacity is a common constraint, especially for smaller systems, and often determines the maximum duration footage can be kept. Whether you want your home camera to capture footage of suspicious activity or need business footage archived for compliance, several technical and operational factors play a role. From the type of system you use to the resolution settings and industry-specific regulations, each component affects how long your security system can store footage before it gets overwritten. Selecting the right storage system and storage option is essential to ensure your retention needs are met.

Learn What to Look for in a Home Security Camera System

Type of Security Camera System

Security systems vary widely in how they store footage:

• CCTV cameras are commonly used in business and public surveillance, with storage capacity depending on system configuration, such as the type of recorder and storage method.
• Cloud-based Security Camera Systems store footage on remote servers and typically offer 7 to 90 days of storage based on subscription level. Some premium plans extend that to 180 days or even a full year.
• DVR/NVR Systems (Digital/Network Video Recorders) store data locally and can retain 30 to 90 days or more, depending on the hard drive capacity. Digital video recorders (DVRs) are used with analog CCTV cameras and connect via coaxial cables, making them a cost-effective choice for basic security systems. Network video recorders (NVRs) are designed for IP cameras and can manage multiple IP cameras simultaneously, allowing centralized storage and management of surveillance footage. These systems are ideal for large setups with multiple cameras and long retention needs.
• SD Card Storage is common in standalone or battery-operated cameras, offering 7 to 30 days of retention. These systems are convenient for limited coverage areas or homes with minimal surveillance needs.

Storage Capacity & File Size

How long footage can be retained heavily depends on the size of the storage drive and how big each video file is. The following factors influence file size:

• Video resolution: 1080p requires less space than 4K video quality. The higher the resolution, the more detail and improved image quality—but also the more storage required.
• Frame rate: Higher frame rates (like 60fps) create smoother video but consume more space than lower rates (like 15fps).
• Video compression: Modern codecs like H.265 can reduce file size by half compared to H.264, increasing your storage efficiency significantly.

By optimizing compression methods and adjusting resolution, you can maximize storage capacity without compromising video quality.

Recording Mode

The camera’s recording behavior can also affect retention:

• Continuous Recording captures 24/7 footage, quickly filling up storage.
• Motion-activated Recording only records when movement is detected, preserving space and extending retention. Motion detection cameras can be configured to record solely when movement is detected, optimizing storage. Users can also adjust motion detection settings to tailor recording to specific areas or movement patterns, reducing false alarms and managing storage more efficiently. This mode is particularly effective in low-traffic areas or at night.
• Scheduled Recording allows users to set cameras to record only during specific times, such as at night, which further extends storage capacity by avoiding unnecessary footage.

Local vs. Cloud Storage Differences

• Local storage such as DVR/NVR systems or SD cards gives you physical control over your footage but is limited by the installed hardware’s capacity. There’s no subscription, but upgrading storage may involve hardware replacement.
• Cloud storage offers virtually unlimited space based on your plan. It provides added security via off-site backups and is ideal for remote monitoring, but it comes with recurring costs and relies on a stable internet connection. Cloud storage solutions also offer enhanced accessibility and security for stored footage, making them a popular choice for both businesses and homeowners.

Retention Settings & Overwriting Mechanism

Many security camera systems, regardless of type, use loop recording, which means the oldest footage is overwritten once storage is full. In this process, older footage is automatically deleted or overwritten to make space for new recordings. The retention period, or the specific duration for which footage is stored before being deleted or overwritten, can often be configured to comply with legal or organizational requirements. However, you can often configure these settings. Some systems allow:

• Disabling overwriting altogether (until storage is full)
• Setting alerts when storage nears capacity
• Exporting or backing up important clips before they are deleted

Legal & Industry Regulations on Footage Storage

For businesses, especially in regulated industries, retention periods are often mandated by law:

• Retail and hospitality typically store footage for 30 to 90 days.
• Healthcare facilities may require 30 days to several years of footage, depending on HIPAA or equivalent laws.
• Banks and casinos often must retain footage from 6 months to 1 year or longer.

Organizations typically retain footage for periods ranging from 30 days to several years, depending on industry standards and legal mandates.

Failing to comply with these regulations could result in fines or liability in case of legal proceedings. As such, it’s critical for commercial entities to plan retention periods that meet or exceed industry norms

How Long Different Types of Security Cameras Store Footage

When evaluating how long different types of security cameras store footage, it helps to compare systems side by side. While most security camera footage is typically stored between 30 and 90 days, storage time still depends heavily on the system's purpose, storage method, and configuration settings. Below is a simplified table highlighting typical retention periods and notable characteristics across popular camera types:
