Evercam
Evercam is a free, open source, closed-circuit television software application designed to be run as SaaS. Evercam originated as a proprietary VSaaS application in 2010 by Irish company Camba.tv Ltd who published the source code to the public under the Affero General Public License (AGPL) licence in April 2015
Uses of the software include security, supply chain monitoring, and Enterprise Resource Planning integrations.
Evercam earns revenue by providing the Software as a Service, a business model that is increasingly common amongst open source companies.
