Cloud-Based vs Traditional Security Systems: What’s the Difference?

There are two major types of security systems being widely used today. These are traditional security systems and cloud-based security systems. Understanding the key differences between these two can help both individuals and organisations select the best option for their security needs.

Below we explore the distinctions between traditional and cloud-based security systems, focusing on accessibility, data security, maintenance and scalability to help you decide which is the best option for you.

Accessibility

Accessibility is one of the most obvious differences between traditional and cloud-based security systems. Traditional systems usually rely on hardware such as control panels and local storage devices. This often means that to manage the system, you need to be physically present at the location or at least connected to the local network. This reduces flexibility, especially for business owners or homeowners who are frequently away from their premises.

Cloud-based surveillance systems, however, offer remote access through internet-connected devices like smartphones or computers. Users can monitor their properties, receive real-time notifications and change settings from anywhere with an internet connection.

Data Security

Data security is a major factor in any security system. Traditional systems usually store data locally, on physical devices such as hard drives or servers. This allows users to have direct control over their data. However, local storage also carries inherent risks. Physical damage (from fires or floods) or theft can destroy stored data. This means manual backup procedures are often required, and critical records may be lost or corrupted.

Cloud-based domestic and industrial surveillance camera systems store data on remote servers, usually managed by service providers. They utilise advanced encryption technologies to safeguard data and maintain multiple layers of cybersecurity, including firewalls, intrusion detection and security audits. This may offer a higher level of protection than individuals or small organisations can manage on their own. Additionally, as data is stored off-site, it is protected from physical disasters.

Maintenance

Traditional systems require ongoing hands-on maintenance, including hardware inspections or updates. These need to be installed manually, which can cause delays. Neglecting this maintenance can lead to vulnerabilities and system failures.

Cloud-based security systems simplify maintenance by shifting much of it to the service provider. Updates are automatically deployed to domestic and industrial video surveillance systems without user intervention. Providers also monitor system health, resolving issues before they become serious. Consistently running the latest and most secure software version reduces the risk of breaches.

Scalability

Adding new components to traditional systems, such as cameras or sensors, usually involves additional hardware installation and potential downtime. This can be costly and time-consuming.

Cloud-based systems offer greater scalability as many devices connect through the internet and are managed centrally. New devices can be integrated with minimal physical installation, making cloud-based solutions ideal for growing businesses.

When choosing between traditional and cloud-based security systems, it’s important to weigh the advantages and limitations of each. Traditional systems provide direct control over data and can function without relying heavily on internet connectivity. However, they tend to be less flexible and require more hands-on maintenance.

Cloud-based security systems offer a more adaptable and secure option in today’s digital landscape. Their convenience makes them increasingly popular for both residential and commercial applications.
