# Introduction
|
|
|
|
Moonfire NVR is an open-source security camera network video recorder, started
|
|
by Scott Lamb <<slamb@slamb.org>>. It saves H.264-over-RTSP streams from
|
|
IP cameras to disk into a hybrid format: video frames in a directory on
|
|
spinning disk, other data in a SQLite3 database on flash. It can construct
|
|
`.mp4` files for arbitrary time ranges on-the-fly. It does not decode,
|
|
analyze, or re-encode video frames, so it requires little CPU. It handles six
|
|
1080p/30fps streams on a [Raspberry Pi
|
|
2](https://www.raspberrypi.org/products/raspberry-pi-2-model-b/), using
|
|
less than 10% of the machine's total CPU.
|
|
|
|
**Help wanted to make it great! Please see the [contributing
|
|
guide](CONTRIBUTING.md).**
|
|
|
|
So far, the web interface is basic: a filterable list of video segments,
|
|
with support for trimming them to arbitrary time ranges. No scrub bar yet.
|
|
There's also an experimental live view UI.
|
|
|
|
<table>
|
|
<tbody>
|
|
<tr valign=top>
|
|
<td><a href="screenshots/list.png"><img src="screenshots/list.png" width=360 height=345 alt="list view screenshot"></a></td>
|
|
<td><a href="screenshots/live.jpg"><img src="screenshots/live.jpg" width=360 height=212 alt="live view screenshot"></a></td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
|
|
There's no support yet for motion detection, no https/TLS support (you'll
|
|
need a proxy server, as described [here](guide/secure.md)), and only a
|
|
console-based (rather than web-based) configuration UI.
|
|
|
|
Moonfire NVR is currently at version 0.6.7. Until version 1.0, there will be no
|
|
compatibility guarantees: configuration and storage formats may change from
|
|
version to version. There is an [upgrade procedure](guide/schema.md) but it is
|
|
not for the faint of heart.
|
|
|
|
I hope to add features such as video analytics. In time, we can build
|
|
a full-featured hobbyist-oriented multi-camera NVR that requires nothing but
|
|
a cheap machine with a big hard drive. There are many exciting techniques we
|
|
could use to make this possible:
|
|
|
|
* avoiding CPU-intensive H.264 encoding in favor of simply continuing to use
|
|
the camera's already-encoded video streams. Cheap IP cameras these days
|
|
provide pre-encoded H.264 streams in both "main" (full-sized) and "sub"
|
|
(lower resolution, compression quality, and/or frame rate) varieties. The
|
|
"sub" stream is more suitable for fast computer vision work as well as
|
|
remote/mobile streaming. Disk space these days is quite cheap (with 4 TB
|
|
drives costing about $100), so we can afford to keep many camera-months
|
|
of both streams on disk.
|
|
* off-loading on-NVR analytics to an inexpensive USB or M.2 neural network
|
|
accelerator and hardware H.264 decoders.
|
|
* taking advantage of on-camera analytics. They're often not as accurate, but
|
|
they're the best way to stretch very inexpensive NVR machines.
