Dummy alarm box blue flashing light affecting night vision

Hi all, I’ve installed a Stick up cam to the front of my garage and I also have a Dummy alarm box which flashes with a blue LED light. But if I look at live view the the view I see keeps flashing on and Off, I disabled “Infrared Lights for Night Vision” and now the flashing on and off of the view has gone but I can’t see my driveway. Do you think its the Blue light that causing the problem? Tomorrow I will remove the batteries from the Dummy box and see if that cures it, if it does do you think that replacing the Dummy box with a red flashing light would do the trick, or just get rid of it
