Recording by input status

I have a site that requires recording on a number of cameras, based on the status of an input that is connected to the system.

I have been testing this on my own system, using an I/O module.

I have created a system rule, that says to start recording when the input is triggered, and to remain recording for the duration of the event. This seems to be working OK, but I’m wondering if we can improve on it at all.

As I only want those cameras to record when the input is triggered, should I set the cameras to ‘Do not record’ under the schedule within the setting for the relevant camera?

This is what I’ve done for now. My main concern is that doing this seems to mean that the smart motion search does not work, on the footage recorded when the input is triggered. I guess it just reverts to ‘record always’ while the condition in the rule is met, but does this necessarily have to mean that we can't have any motion searching on that recorded footage?

Is there a way around this? I am very much open to suggestions on this matter.

Thanks
