In order to help manage CPU load, I've set up each camera with two monitors, one high resolution and framerate on the main stream, set to "nodect" and one low resolution, lower frame rate set to "modect" on the secondary stream from the same camera. I do motion detection on the secondary, low-res stream, and link the higher fidelity monitor to that alarm for recording.

This seems to work quite well, I've got my CPU load under control, and I end up with nice looking recordings from the higher quality monitor. However, I end up with two recordings of everything, which I don't need. One from the lo-res stream and one from the hi-res stream.

There doesn't seem to be a "do motion detection but don't record" setting. It's a bit unclear if tweaking the buffer sizes affects the recording or also the motion detection analysis. And as I'm not one for randomly playing with parameters without really understanding what I'm doing, I'd rather just ask if there's a straightforward way to achieve this.

Thoughts?

Set a filter to delete the recordings, based on the monitor, you do not want.

While that's a possibility, I would prefer a solution that doesn't load the machine at the same time it's trying to record a high fidelity image, just to have the results thrown away.

Is there no way to actually not do the recording?

It would be great to have a "motion detect only" mode! I could use my low-res cameras like you are.

I second. I really like the way you are using your cameras. But double recording is a bust. My system also acts as a plex server and a home automation server. Like saving processor power.
