Re: [Motion-user] Looking for outdoor wireless camera w/night vision

But there's a step between mjpeg and h264, correct?

For that reason I configured Motion to quickly send snapshots on the SFTP server while actual recording stayed on the local machine, but it always ended up crashing the router due to connections overload (more than 4000 at a time), as it didn't close them after uploading. Motion was completely useless then.

In an enclosure, there is going to be additional warmth from the electronics (and AC adapter, if you put it in there), so take that into consideration. If you are using wired ethernet or wifi, the USB won't be needed.

Nothing about temperature and humidity levels? I think the board can bear it, but would like to be sure, especially to avoid fogging the exterior-facing glass.

If you want to use a different motion detection approach, you could simply use the h264 from raspivid, which takes advantage of the hardware encoding via OpenMax. I don't know of anyone doing dual streaming, though I won't say you can't do it. You could always come up with a dual streaming approach on your own, though be advised that would fall into the 'tinkering and tweaking' category you want to avoid.
