CCTV storage: local vs cloud
We all know how important CCTV footage is when it comes to public and private security, but when it comes to keeping the actual video footage safe, what’s the best way to store data? Generally speaking, there are two main options: local storage and cloud storage. In this article, we'll explore the differences between these two options and help you determine which one is right for your needs.
What is local storage?
Local storage refers to the practice of storing CCTV footage on-site, typically using a digital video recorder (DVR) or network video recorder (NVR). These devices are connected directly to the cameras and store the footage on hard drives or other storage media.
Typical local storage solutions
Common local storage solutions for CCTV footage include DVRs with built-in hard drives, NVRs with external storage devices, and dedicated servers with large storage capacities.
What is cloud storage?
Cloud storage, on the other hand, involves storing CCTV footage on remote servers accessed via the internet. This allows users to access their footage from anywhere with an internet connection, without the need for on-site storage infrastructure.
How cloud storage works
When using cloud storage for CCTV footage, the cameras stream their video to a remote server, where it is stored and can be accessed by authorised users. This process typically involves encoding the video stream, uploading the encoded video to the cloud server, storing the video on the server's storage infrastructure, and providing access to authorised users via a web interface or mobile app.
Pros and cons of local storage for CCTV footage
Pros of local storage
One of the main advantages of local storage is that there are no recurring costs once you've invested in the necessary hardware. Additionally, local storage doesn't require an internet connection, making it suitable for areas with poor or unreliable connectivity. With local storage, you have complete control over your data and can ensure it remains secure and private.
Cons of local storage
However, local storage devices have finite storage capacity, which may require frequent overwriting of older footage. They’re also susceptible to physical damage, theft, or malfunction, which could result in data loss. Accessing locally stored footage remotely can be challenging and may require additional hardware or software.
Plus, in some cases you may need to blur a video online before sharing it with others to protect the privacy of individuals captured in the footage, so consolidating everything in a digital space might be more helpful.
Pros and cons of cloud storage for CCTV footage
Pros of cloud storage
Cloud storage offers scalability, allowing it to easily accommodate growing storage needs without requiring additional hardware investments. It also enables remote access, allowing access-privileged users to access footage from anywhere with an internet connection, making it ideal for monitoring multiple locations. Cloud storage providers also typically offer automatic backup and redundancy, ensuring that footage is always available even if one server fails.
Cons of cloud storage
On the downside, cloud storage often involves ongoing subscription fees, which can add up over time. It also requires a stable and fast internet connection, which may not be available in all locations. Storing footage on remote servers may additionally raise security and privacy concerns, particularly if the cloud provider experiences a data breach.
Which is better: local or cloud storage?
Factors to consider
When deciding between local and cloud storage for your CCTV footage, consider the size and complexity of your CCTV system, your budget for upfront costs and ongoing expenses, the availability and reliability of internet connectivity at your location, your security and privacy requirements, and the level of technical expertise available to manage your storage solution.
Making the right choice for your needs
When choosing between local and cloud storage for your CCTV footage, consider the following factors to ensure you make the best decision for your organisation's needs:
Assess the size and complexity of your CCTV system. If you have a large, multi-site operation, cloud storage may be more suitable due to its scalability and remote access capabilities. However, if you have a smaller, single-site setup, local storage might be sufficient and more cost-effective.
Evaluate your budget for both upfront costs and ongoing expenses. Local storage requires a larger initial investment in hardware but has no recurring costs, while cloud storage has lower upfront costs but involves ongoing subscription fees.
Consider the availability and reliability of internet connectivity at your location. If your area has poor or unreliable internet, local storage may be a more practical choice. Cloud storage, on the other hand, requires a stable and fast internet connection to function effectively.
Prioritise your security and privacy requirements. If you have strict data protection policies or handle sensitive information, local storage provides complete control over your data. However, reputable cloud storage providers often employ robust security measures to safeguard your footage.
Evaluate the level of technical expertise available within your organisation. Local storage may require more in-house technical knowledge to set up and maintain, while cloud storage is typically managed by the provider, requiring less technical expertise on your end.
Final thoughts
As CCTV cameras become increasingly common, it's important to have a reliable and secure storage solution for the footage they generate. And whether you choose local or cloud storage, investing in a robust CCTV storage solution is essential for protecting your property and ensuring the safety of your community. By simply understanding the differences between local and cloud storage, you can make an informed decision that meets your security needs and budget.
