Record It Locally

Your cameras work fine until the subscription email arrives, or until you need the clip from six days ago and the history stops at three. The footage of your own front door lives on somebody else's server, under terms they can change. There is another way to build this, and it is not harder — it is just different. A local-first system means the camera produces a standard video stream on your network, and a recorder you own writes it to a disk you own. No subscription. Nothing leaving the building. Cameras that keep recording when the internet is down. This book walks you through the whole build, in order: how to tell an open camera from a locked one before you buy, where cameras actually have to be mounted to identify a face instead of just proving somebody was there, how to size a disk with arithmetic instead of guesswork, how to put cameras on your network without exposing them to the internet, and how to tune object detection until you have alerts you still trust a month later. It is written for someone practical who is not a network engineer. You will be told plainly what this costs you in effort, where a beginner should stop and hire out, and what a camera system honestly can and cannot do. By the end you will own a stream, a recorder, and a disk — and nobody can change the terms on you.
