Not open source, but fairly open standard, I'm in love with Milestone XProtect Essential+[1] because I'm a Windows Server guy.

Free for 8 cameras, has extremely universal support for cameras (you can add in RTSP streams, Onvif, MJPEG/HTTP grab, etc) and some really good SDK support[2] - and a PowerShell module[3] to boot.

And, more importantly, a really good view on ethics[4]:

> We require employees, partners, and customers to comply with applicable laws and to respect human rights. We do not accept discrimination, human rights violations, violations of child labor laws. We have incorporated human rights language into our licensing terms, which were supplemented by the Copenhagen Clause in 2019.
