Understanding how long security cameras store footage is crucial for effective security, especially when it comes to your business. Missing important footage can leave gaps in addressing incidents. This article explains why the right storage duration matters for spotting threats, analyzing trends, and maintaining a strong security system.
How long do security cameras keep footage on average?
Different types of business have different video retention needs, but as a general guideline footage recorded by security systems should be retained for a minimum of 30 days. Certain industries, for example cannabis or financial services, may be required to maintain more than a year of security footage on-site and/or in the cloud.
Furthermore, businesses may choose to retain, for example, 90 days of standard definition (SD) video but only 14 days of high-definition (HD) video. This gives them the long-term coverage needed for internal theft investigations as well as the time required to save and share major incidents with law enforcement, insurance companies, and any other stakeholders.
Retention of security footage can help in many different ways. It isn’t only theft or shrinkage where video retention can help, security camera systems can also record events related to liability. For example, if an employee or customer is injured, security footage can be pivotal to demonstrate who was at fault. Liability issues often do not surface for several months, making longer video retention a practical way to protect your business from unforeseen risks.
Where can security camera footage be stored?
Security camera footage can be stored in several ways, each offering distinct benefits:
- On-site storage: Footage is stored on physical devices such as DVRs (Digital Video Recorders) or NVRs (Network Video Recorders) located at your business. This method provides quick access to recent recordings but can be at risk of theft, tampering, or damage due to events like fires or floods.
- Cloud storage: Footage is stored on remote servers accessed via the internet. This method offers secure, scalable storage and allows you to access footage from anywhere with an internet connection. Cloud storage is ideal for protecting data from physical damage or theft and often includes automatic backups and enhanced security features.
- Hybrid storage: Combines on-site and cloud storage. Critical footage is stored on-site for immediate access, while backups are kept in the cloud for long-term security. This approach provides the benefits of both methods, ensuring quick access to important footage while maintaining a secure backup off-site.
Choosing the right storage method depends on your business needs, budget, and security requirements. Assess your priorities to decide which option offers the best balance of accessibility and safety for your security footage.
Retention time for each individual storage type
Here’s a breakdown of different storage options and their typical retention times:
On-site storage | 7 days to several months | Footage stored on physical devices (DVR/NVR) at your location. Retention time depends on storage capacity and recording settings. Quick access but vulnerable to theft or damage. |
Cloud storage | 30 days to several years | Footage stored on remote servers, accessible via the internet. Secure, scalable, and protected from physical damage. Often includes automatic backups and enhanced security. |
Hybrid storage | Same as above | Combines on-site and cloud storage. Critical footage is stored on-site for quick access, with secure backups in the cloud for long-term protection. Flexible and enhances data security. |
Key elements affecting camera storage capacity
Several factors influence the storage capacity of security cameras:
Resolution: Higher resolution footage requires more storage space. Cameras recording in 4K will use more storage compared to those recording in 1080p or 720p.
Frame rate: Higher frame rates (e.g., 30 fps) create smoother videos but consume more storage than lower frame rates (e.g., 15 fps).
Compression technology: Advanced compression formats like H.265 reduce file sizes more efficiently than older formats like H.264, extending storage capacity without sacrificing quality.
Recording settings: Continuous recording uses more storage than motion-triggered or scheduled recording. Adjusting these settings can help manage storage needs.
Number of cameras: More cameras recording simultaneously will require more storage space. The combined data from all cameras must be factored into overall capacity planning.
Retention period: Longer retention times require more storage. Decide how long you need to keep footage based on your business needs and legal requirements.
Storage hardware capacity: The physical capacity of DVR, NVR, or cloud storage plans impacts how much footage can be stored. Larger hard drives or higher-tier cloud plans offer more storage space.
By understanding and managing these factors, businesses can optimize their storage solutions to meet their security needs efficiently.
Tactics to keep security camera footage for longer
To extend the retention period of your security camera footage, consider the following tactics:
Optimize resolution and frame rate: Lowering the resolution and frame rate of your recordings can significantly reduce storage requirements, allowing you to keep footage for longer periods.
Use advanced compression: Implement advanced compression technologies like H.265, which reduce file sizes more efficiently than older formats such as H.264, extending your storage capacity without sacrificing video quality.
Enable motion detection recording: Configure your cameras to record only when motion is detected. This minimizes the amount of footage stored, conserving space and extending retention times.
Invest in additional storage: Upgrade your DVR, NVR, or cloud storage plan to a higher capacity option. Larger storage solutions can hold more footage, allowing for longer retention periods.
Regularly archive important footage: Periodically review and archive critical footage to external storage devices or cloud services. This frees up space for new recordings while preserving important data for long-term use.
Adjust retention settings: Tailor your retention settings based on your business needs. Determine the optimal balance between retention time and available storage, and adjust settings accordingly.
Use hybrid storage solutions: Combine on-site storage with cloud backups. Store immediate access footage locally while keeping long-term backups in the cloud, ensuring extended retention without compromising accessibility.
Implementing these strategies can help maximize your storage efficiency and ensure that you retain important security footage for as long as necessary.
Conclusion
Understanding how long the average security camera stores footage is vital for effective security management. Implementing the right storage strategy ensures that critical footage is available when needed, enhancing overall security and peace of mind.
