These days, as cloud technologies continue to grow, more and more cloud-based apps are appearing. But are they really safe? And should they be used in areas like video surveillance or security systems?
Let’s take video surveillance as an example. Many system designers use cloud services regularly. For developers, cloud apps are often easier and faster to build compared to traditional desktop programs.
Cloud Solutions – Pros and Cons
Pros:
- Work on almost any device (PCs, tablets, etc.)
- Not tied to one operating system
- Accessible from anywhere with internet
- Less affected by piracy
These benefits make cloud apps convenient and flexible for many users.
Cons:
- Risk of data leaks or hacking
- Employees can make mistakes that lead to data loss
- Vulnerable to DDoS attacks
- Weak spots in APIs and user interfaces
- Dependence on the service provider (if they shut down, your data may go with them)
- Developers can access usage data
These risks become especially serious when sensitive or confidential information is involved.
Overall, cloud apps are not as secure as those that store everything locally on your own computer—unless you choose to back them up to the cloud yourself.
Desktop (Local) Applications
Pros:
- Data stays on your device
- No need for internet to run
- Keeps working even if the developer goes out of business
Cons:
- Works only on supported devices
- Needs specific hardware and operating system
While desktop apps aren’t always cross-platform, a key benefit is that you own the data. Many now offer cloud backups—but only if you allow it. Some even support collaboration when needed, again with your permission.
So, these programs are often better for users who care about control and privacy.
What About Local-First?
A newer approach called local-first is getting more attention. These apps store and process data directly on the user’s computer, but can also sync with a server when internet is available. This way, you can keep working offline, and everything updates when you’re back online.

Conclusion
If security and privacy are important in your project, traditional desktop software or local-first solutions are usually the better choice. They help reduce the risks of data leaks, service outages, and reliance on internet or third-party providers.
