Open Source NVR
A camera system records the most sensitive footage you own - the inside of your home or office, around the clock - so the real question is not picture quality but where those frames live, and a vendor cloud means your private video sits on hardware you do not control. The open source NVR software here ingests and records standard camera streams to storage on your own network, so the footage stays local, the retention is yours to set, and no subscription stands between you and your own recordings.
