Motion detection setup

Hi,

I'm pretty sure this was discussed before, but I'm unable to find a clear conclusion on it.

Which way is better for motion detection for cameras with 2 streams? Having low-res as modect and high resolution as nodect and linked or perform directly modect on high resolution stream? In my setup load never goes under 1.7 no matter on how the setup is. Only if I completely shutdown the HI-res stream but that is nonsense.

Also for zones, is better to have multiple and smaller zones or one bigger? I'm monitoring a contiguous area. I just realised I have better motion detection on blobs if I have multiple areas. Still don't see any major improvement on load.

I'm asking because I need to add more cameras and I'm afraid my old Dell Optiplex 980 (i5 cpu) will not be able to handle them.

I will really appreciate if you can point me in the right direction. Thank you in advance.

Multiple zones let you avoid false trigger areas. I use that method to avoid shadows that trigger, tree limbs, etc.
Just plan on spending time tuning the zones.
I have not toyed with the idea of triggering off a lower resolution stream.

Thanks. For now I'm with modect on low-stream and nodect in high-stream. multiple zones only on what I need to see. But still load is always ~1.7.
