I have a starlight camera and yes they blur on moving objects.

Thanks.

It doesn't use long shutter times but integrates many frames (512 max I
think).

Sure ... but that worked as a practical overview of *why* it happens.
;-)

It's because there's little or no light.



I don't use it as a security cam.

Ok.

The PIR light is probably the best if the camera can switch to daytime
colour fast enough.

... depending on how long the subject is there to view or how much
footage (can I say that or should I say 'megabytes of video data' g)
you have captured to review?

and the sensor isnl;t sensitive enough to 'see' the light.


I would like a Starlight camera to play with but not sure if there any
VFM models worth having (I believe my recorder (Alien MEGAHero)
supports 1080p FWIW).

Star light camera to me, means the 'camera' has to have an image
intensifier attached to it, these can be expensive, the sort of thing
you'll get in military binocluars and gun sights.
Modern smartphones can use clever algorithims to artificaly lighten a
subject.

They dont artificially lighten the subject, they combine multiple
images, much closer to a long exposure but without the smearing.

The othe roption is to illuminate the subject with a IR
lamp, this is the sort of thing they use for security cameras.

Not sure which would be easist to set up for what yuo want to do,
but here they do describe things a little better than purhaps I have.
