Building a security surveillance system for home or business security, often cost a large sum of money, that include hardware, software, setup, and maintenance.

Security surveillance software solutions like CCTV systems, IP camera monitoring programs, DVR apps and NVR apps, are regularly commercial programs. Which means they cost money for subscription or buying a version that you need to pay more to upgrade or renewing the license.

As they vary in price and features, we put together open source and free alternatives to setup your security system without the need to worry about license or vendor lock-in.

Here, in this list we offer you the best open-source and free solution that can help you use old USB cameras, even your old mobile phone camera to setup a strong surveillance system.
