Zmodopipe is a tool that can take the stream from certain model of DVRs and provide that stream through a Named Pipe where programs, including Zoneminder (through
zm_ffmpeg_camera.cpp) and ffmpeg can read that stream.
This repository is a fork of zmodopipe created by Daniel Osborne (Phoenix84 on ZoneMinder Forums). This project has not been updated since 2013, but it was documented here[1] and discussed here[2].
Daniel put his work in the public domain, and I wanted to make sure it was stored reliably so that it may continue being used. This repository remains in the public domain as well.
