I'm not sure how you've implemented the "continuously recording"
(perhaps by setting 'emulate_motion on'?)? but you could just add
scripts to 'on_camera_lost' and 'on_camera_found' which turns off and on
the option being used via the webcontrol.
e.g.
!#/bin/bash
curl http://{yourip}:{port}/{threadid}/config/set?emulate_motion=on

You can also try the despeckle filter
https://motion-project.github.io/motion_config.html#despeckle_filter
It could also be helpful to save a night time false-positive movie file
and then send it back through motion as a static file with the
setup_mode on.? This would allow you to see the motion which is
triggering it in the 'motion' stream.
https://motion-project.github.io/motion_config.html#Basic_Setup_Static
https://motion-project.github.io/motion_config.html#setup_mode
(Note that if you are building from source, some of this is a bit easier
in the latest master branch.)

I did for a while...USB camera outdoors and connected to a PI that was
indoors and then put the images/movies into the house. It worked but
generally poor performance with low resolution. Then tried a more
powerful computer and hooked all the USB cameras to that computer...only
to find that the USB bus hits the maximum bandwidth with only one
camera.? Plan on only one camera per USB bus.? Ultimately, I upgraded to
POE IP cameras as they were much cheaper in aggregate and at the same
time provided higher resolution/performance.
Wish I had just done the IPs from the start as the USB cameras and PIs
are now pretty much just in a shoe box.

ELP makes a nice USB security camera for about $40. Works with one
Orange Pi One per camera but need to limit frame rate or drop
resolution if using motion. Camera on outside, computer inside attic
space. Using POE and POE adapter can be cheaper than having an
electrician add sockets to get AC power to provide the 5V.
The bottleneck seems to be poor encoder on most low end SoC. Nearly
impossible to get a VP8/VP9 encoder today. Seems to be improving but
might take a few years. For now lossy h264 packed into avi seems to
be called for, which is pretty much what you get from the SoC built
into the camera, whether USB or IP camera.
