Depending on your industry, you may need to install and run video surveillance. And once you have footage, you might be required to store it for a set period of days, months, or even years. This leads to the question: Where are you supposed to keep it all?

Not all storage systems are created equal, so it’s important to weigh the benefits and drawbacks of each option before making a decision. In some cases, government and industry regulations will require you to use a certain type of storage system. Ultimately, you will benefit from knowing how the system functions, what risks are involved, and how to select a technology provider.

This article will help you consider the pros and cons of on-premises, cloud, and hybrid storage systems. As you read, keep in mind that the amount of storage you need for your enterprise will depend on the number of cameras you have, the quality of the video footage, the length of time you are required to retain the footage, and various other factors. 

First Things First: Your Backup Strategy

No matter how or where you store your video surveillance footage, the most important thing you should do is establish a backup strategy that follows the 3-2-1 backup approach. That means you should have three copies of your data on two different media with one stored off-site. In this post, we’ll weigh the pros and cons of whether you keep that off-site copy stored at an off-site location like, say, an Iron Mountain storage facility, a remote office, or data center, or whether you keep that off-site copy in the cloud. 

You might think we’re biased as a cloud provider. Of course, we’d love it if you choose to keep your backups with Backblaze! But the main thing we want to emphasize is that you should have a backup plan for your video surveillance footage (or any data, really!) whether it includes Backblaze or not. And, because you have to store one of those copies off-site, it’s miles easier (pun intended) to store in the cloud than to physically drive or mail hard drives to a secondary location.  

What Is On-Premises Storage?

Storing video footage on-premises means your data is stored on physical media—that is, servers, network attached storage (NAS), storage area network (SAN), LTO tape (linear tape open), etc.—in a physical location on your premises. We’ll talk about two forms of on-premises storage as they pertain to video footage: NAS and SAN.

Are NAS Devices Good for Storing Video Footage?

NAS devices have a large data storage capacity that provides file-based data storage services to other devices on a network. Usually, they also have a client or web portal interface, as well as services like QNAP’s Hybrid Backup Sync or Synology’s Hyper Backup to help manage your files.

One of the benefits of NAS is that it’s easy to set up and use, and you can upgrade internal drives over time. The main drawback when it comes to storing video surveillance footage is that its storage capacity is limited. Even if you buy a bigger device than you need right now, eventually you’ll run out of space and need to buy more, especially if you’re storing large amounts of video surveillance footage.

Is a SAN Good for Storing Video Footage?

On the other end of the spectrum, SANs are engineered for high-performance and mission-critical applications. They function by connecting multiple storage devices, such as disk arrays or tape libraries, to a dedicated network that is separate from the main local area network (LAN).

SANs offer high-speed data access, critical for handling large video streams from multiple cameras and allow for seamless scalability. As video surveillance systems grow, SANs can accommodate additional cameras and storage without disrupting ongoing operations. They also provide enhanced data security by isolating block-level storage within the operating system layer, to protect against failures and unauthorized access. Managing SANs can be a bit complex, necessitating skilled administrators familiar with SAN architecture. Additionally, implementing SANs incurs upfront expenses for hardware, software, and expertise, while their reliance on centralized controllers poses a risk of impacting multiple cameras in case of failure.

What Is Cloud Storage?

Cloud storage enables you to securely store data and files in an off-site location. You can access this data through the public internet.

When you transfer data off-site for storage, the cloud storage provider (CSP) hosts, secures, manages, and maintains the servers and associated infrastructure, ensuring that you have seamless access to your data whenever you need it.

What Are the Benefits of Cloud Storage for Video Surveillance Footage?

1. Scalability: Cloud storage services allow you to dynamically adjust capacity as your video surveillance data volumes fluctuate. 
2. Avoid capital expenses (CapEx): By leveraging cloud storage for video surveillance, your organization benefits from paying for storage technology and capacity as a service, rather than incurring the capital expenses associated with constructing and upkeeping in-house storage networks. As data volumes grow over time, your costs may increase, but there’s no need to overprovision storage networks in anticipation of future data expansion. 
3. Security: Cloud surveillance systems enhance data security with unique user accounts and data encryption ensure that only authorized personnel can access the footage. This controlled access minimizes the risk of unauthorized viewing or tampering.
4. Accessibility: Cloud storage relies on an internet or network connection so authorized users can access surveillance footage remotely from anywhere using smart devices or web browsers. Whether you’re at the office, traveling, or even at home, you can review camera feeds without being physically present on-site. Keep in mind if the connection is lost or disrupted, access to video footage becomes challenging. This dependency can impact real-time monitoring and retrieval of critical data.

Just like our other storage strategies, there are drawbacks to cloud storage. For example, it relies on a stable internet connection. Video surveillance files are large, even when you apply compression techniques, which means that they take time and proper network connections to upload. So, if your internet connection goes down, it takes longer to get data properly stored or backed up than it would with other file types. That means you may not have real-time access to your data, or (in the worst cases) that you potentially risk file corruption if you don’t have a robust enough local storage infrastructure. 

Similarly, businesses should evaluate the privacy and data ownership concerns. Storing video footage in the cloud means entrusting sensitive data to a third-party service provider. Make sure that your CSP meets or exceeds all regulatory or compliance requirements, like SOC 2 or ISO 27001, before you store data on their platforms. 

All things considered, cloud storage offers scalability, ease of access, fine–tuned file control, and minimal maintenance, which are essential when dealing with the complexities of storing video surveillance footage.

Direct-to-Cloud Video Surveillance

Some companies choose to transfer video surveillance off-site to the cloud for backup purposes, while others push video footage directly to the cloud as a primary storage location, especially as there are several camera models and video surveillance solutions that are designed to easily push footage directly to cloud storage. When you’re choosing video surveillance hardware, it’s worth looking into whether they have this functionality, and if so, how much control you have over setting your storage destination to optimize costs. 

And, if you’re using cloud storage as the primary storage for video footage, a multi-cloud setup can be used to ensure the primary copy in the cloud is backed up. A multi-cloud setup involves using multiple cloud service providers simultaneously—so, if your video surveillance platform stores footage in their own cloud, you can still set up a workflow that backs up to a different CSP. For backup and archive purposes, organizations can distribute their data across different clouds to enhance reliability, reduce risk, create geographic diversity in storage locations for disaster recovery purposes, and to comply with data retention policies. This approach ensures data availability even if one cloud provider experiences issues.

What Is Hybrid Cloud Storage?

Hybrid cloud storage combines elements from both public clouds and private clouds (typically on-premises systems). It’s essentially a unified management approach where an integrated infrastructure enables seamless movement of workloads and data between the private and public clouds.

Using a hybrid cloud for video surveillance makes sense for lots of use cases, including backup and archive. Let’s talk about how. 

Backup: To deploy a hybrid approach for a video surveillance backup use case, you’d store all of your video surveillance footage in your on-premises systems, then store your backups in the cloud. Many NAS devices, for example, come with on-board backup utilities that allow you to store backups of your video surveillance footage directly in the cloud. You could also use third-party backup software to automatically back up your systems to the cloud. This hybrid approach gives you fast access to your footage via your on-premises storage, while protecting it with cloud backups.

Archive: To deploy a hybrid approach for a video surveillance archive use case, you’d store recent live recordings of your video surveillance footage on-premises. After a recurring cutoff date—whether in days or months—you then move old footage to a public cloud. This hybrid system allows you to access recent footage quickly while archiving older footage, particularly if you have retention requirements for compliance or cyber insurance purposes. If done right, this system can help your company comply with both short- and long-term industry requirements.

Is Hybrid Cloud Good for Video Surveillance Footage?

Leveraging hybrid cloud storage provides a dual advantage for video surveillance: swift local access to your video surveillance footage while simultaneously safeguarding it through off-site backups or off-loading it through a cloud archive. This strategic approach allows you to harness the strengths of both public and private clouds. Moreover, it offers enhanced scalability and flexibility compared to traditional on-premises solutions.

However, it’s essential to note that implementing a private cloud system can be cost-intensive. It necessitates budgeting for hardware acquisitions and replacements over time. Additionally, you’ll likely need to allocate resources for dedicated staff to maintain servers and backup strategies.

The Verdict: Which Type of Storage Is Best for Video Surveillance?

Choosing the right video surveillance storage solution is a critical decision for any organization. On-premises, cloud, and hybrid cloud each have their merits and drawbacks. While on-premises solutions offer large data storage capacity that is easy to set up and use, they require significant infrastructure investment. Cloud storage provides data accessibility and scales seamlessly while optimizing cost-effectiveness. Hybrid cloud provides both rapid local access to your video surveillance footage and secure off-site backups. 

Ultimately, the choice depends on your specific needs, budget, and long-term strategy. Consider the trade-offs carefully to ensure seamless and reliable video storage for your surveillance system.

We all have things we want to protect, and if you’re responsible for physically or virtually protecting a business from all types of threats, you probably have some kind of system in place to monitor your physical space. If you’ve ever dealt with video surveillance footage, you know managing it can be a monumental task. Ensuring the safety and security of monitored spaces relies on collecting, storing, and analyzing large amounts of data from cameras, sensors, and other devices. The requirements to back up and retain footage to support investigations are only getting more stringent. Anyone dealing with surveillance data, whether in business or security, needs to ensure that surveillance data is not only backed up, but also protected and accessible. 

In this post, we’ll talk through why you should back up surveillance footage, the factors you should consider to understand how much storage you need, and how you can use cloud storage in your video surveillance backup strategy. 

The Importance of Backing Up Video Surveillance Footage

Backup storage plays a critical part in maintaining the security of video surveillance footage. Here’s why it’s so important:

1. Risk Reduction: Without backup storage, surveillance system data stored on a single hard drive or storage device is susceptible to crashes, corruption, or theft. Having a redundant copy ensures that critical footage is not lost in case of system failures or data corruption.
2. Fast Recovery: Video surveillance systems rely on continuous recording to monitor and record all activities. In the event of system failures, backup storage enables swift recovery, minimizing downtime and ensuring uninterrupted surveillance.
3. Compliance and Legal Requirements: Many industries, including security, have legal obligations to retain surveillance footage for a specified duration. Backup storage ensures compliance with these requirements and provides evidence when needed.
4. Verification and Recall: Backup recordings allow you to verify actions, recall events, and keep track of activities. Having access to historical footage is valuable for potential investigations and future decision making.

Each piece of information about video surveillance requirements will affect how much space your video files take up and, consequently, your storage requirements. Let’s walk through each of these general requirements so you don’t end up underestimating how much backup storage you’ll need.

Video Surveillance Storage Considerations

When you’re implementing a backup strategy for video surveillance, there are several factors that can impact your choices. The number and resolution of cameras, frame rates, retention periods, and more can influence how you design your backup storage system. Consider the following factors when thinking about how much storage you’ll need for your video surveillance footage:

• Placement and Coverage: When it comes to video surveillance camera placement, strategic positioning is crucial for optimal security and regulatory compliance. Consider ground floor doors and windows, main stairs or hallways, common areas, and driveways. Install cameras both inside and outside entry points. Generally, the wider the field of view, the fewer cameras you’ll likely need overall. The FBI provides extensive recommendations for setting up your surveillance system properly.
• Resolution: The resolution determines the clarity of the video footage, which is measured in the number of pixels (px). A higher resolution means more pixels and a sharper image. While there’s no universal minimum for admissible surveillance footage, a resolution of 480 x 640 px is recommended. However, mandated minimums can differ based on local regulations and specific use cases. Note that some regulations may not provide a minimum resolution requirement, and some minimum requirements may not meet the intended purpose of surveillance. Often, it’s better to go with a camera that can record at a higher resolution than the mandated minimum.
• Frame Rate: All videos are made up of individual frames. A higher frame rate—measured in frames per second (FPS)—means a smoother, less clunky image. This is because there are more frames being packed into each second. Like your cameras’ resolution, there are no universal requirements specified by regulations. However, it’s better to go with a camera that can record at a higher FPS so that you have more images to choose from if there’s ever an open investigation.
• Recording Length: Surveillance cameras are required to run all day, every day, which requires a lot of storage. To help reduce the instance of storing videos that aren’t of interest, some cameras can come with artificial intelligence (AI) tools that will only record footage when it identifies something of interest, such as movement or a vehicle. But if you’re protecting a business with heavy activity, this use of AI may be moot. 
• Retention Length: Video surveillance retention requirements can vary significantly based on local, state, and federal regulations. These laws dictate how long companies must store their video surveillance footage. For example, medical marijuana dispensaries in Ohio require 24/7 security video to be retained for a minimum of six months, and the footage must be made available to the licensing board upon request. The required length can be prolonged even further if a piece of footage is required for an ongoing investigation. Additionally, backing up your video footage (i.e., saving a copy of it in another area) is different from archiving it for long-term use. You’ll want to be sure that you select a storage system that helps you meet those requirements—more on that later.

Each point on this list affects how much storage capacity you need. More cameras mean more footage being generated, which means more video files. Additionally, a higher resolution and frame rate mean larger file sizes. Multiply this by the round-the-clock operation of surveillance cameras and the required retention length, and you’ll likely have more video data than you know what to do with.

Scoping Video Surveillance Storage: An Example

To illustrate how much footage you can expect to collect, it can be helpful to see an example of how a given business’s video surveillance may operate. Note that this example may not apply to you specifically. You should review your local area’s regulations and consult with an industry professional to make sure you are compliant. 

Let’s say that you need to install surveillance cameras for a bank. Customers enter through the lobby and wait for the next available bank teller to assist them at a teller station. No items are put on display, only the exchange of paper and cash between the teller and the customer. Only authorized employees are allowed within the teller area. After customers complete their transactions, they walk back through the lobby area and exit via the building’s front entry.

As an estimate, let’s say you need at least 10 cameras around your building: one for the entrance; another for the lobby; eight more to cover the general back area, including the door to the teller terminals, the teller terminals themselves, the door to the safe, and inside of the safe; and, of course, one for the room where the surveillance equipment is housed. You may need more than 10 to cover the exterior of your building plus your ATM and drive through banking, but for the sake of an example, we’ll leave it at 10.

Now, suppose all your cameras record at 1080p resolution (1920 x 1080 px), 15 FPS, and a color depth of 14 bits (basically, how many colors the camera captures). For one 24 hour recording on one camera, you’re looking at 4.703 terabytes (TB). Over 30 days of storage, this can grow to 141.1TB. In other words, if the average person today needs a 2TB hard disk for their PC, it will take more than 70 PCs to hold all the information from just one camera.  

How Cloud Storage Can Help Back Up Surveillance Footage

Backing up surveillance footage is essential for ensuring data security and accountability. It provides a reliable record of events, aids in investigations, and helps prevent wrongdoing by acting as a deterrent. But the right backup strategy is key to preserving your footage.

The 3-2-1 backup strategy is an accepted foundational structure that recommends keeping three copies of all important data (one primary copy and two backup copies) on two different media types (to diversify risk) and storing at least one copy off-site. With surveillance data utilizing high-capacity data storage systems, adhering to the 3-2-1 rule is important in order to access footage in case of an investigation. The 3-2-1 rule mitigates single points of failure, enhances data availability, and protects against corruption. By adhering to this rule, you increase the resilience of your surveillance footage, making it easier to recover even in unexpected events or disasters.

Having an on-site backup copy is a great start for the 3-2-1 backup strategy, but having an off-site backup is a key component in having a complete backup strategy. Having a backup copy in the cloud provides an easy to maintain, reliable off-site copy, safeguarding against a host of potential data losses including:

• Natural Disasters: If your business is harmed by a natural disaster, the devices you use for your primary storage or on-site backup may be damaged, resulting in a loss of data.
• Tampering and Theft: Even if someone doesn’t try to steal or manipulate your surveillance footage, an employee can still move, change, or delete files accidentally. You’ll need to safeguard footage with proper security protocols, such as authorization codes, data immutability, and encryption keys. These protocols may require constant, professional, and IT administration and maintenance that are often automatically built into the cloud.
• Lack of Backup and Archive Protocols: Unless your primary storage source uses   specialized software to automatically save copies of your footage or move them to long-term storage, any of your data may be lost.

The cloud has transformed backup strategies and made it easy to ensure the integrity of large data sets, like surveillance footage. Here’s how the cloud helps achieve the 3-2-1 back strategy affordably:

•  Scalability: With the cloud, your backup storage space is no longer limited to what servers you can afford. The cloud provider will continue to build and deploy new servers to keep up with customer demand, meaning you can simply rent out the storage space and pay for more as needed.
• Reliability: Most cloud providers share information on their durability and reliability and are heavily invested in building systems and processes to mitigate the impact of failures. Their systems are built to be fault-tolerant. 
• Security: Cloud providers protect data you store with them with enterprise-grade security measures and offer features like access controls and encryption to allow users the ability to better protect their data.
• Affordability: Cloud storage helps you use your storage budgets effectively by not paying to provision and maintain physical off-site backup locations yourself.
• Disaster Recovery: If unexpected disasters occur, such as natural disasters, theft, or hardware failure, you’ll know exactly where your data lives in the cloud and how to restore it so you can get back up and running quickly.
• Compliance: By adhering to a set of standards and regulations cloud solutions meet compliance requirements to ensure data stored and managed in the cloud is protected and used responsibly.
