any way to stop SYSTEM SET IR LIGHT ON / off log msgs

hi folks is there any way to stop SYSTEM SET IR LIGHT ON / off log msgs? they cause a recording and an email to be sent which i'd rather it not.
thanks

FurryNutz:
Leave the IR enabled always or disabled always. Kind of a inconvenience however just happens when it switches during this operation.  :-\

turnbui:
ok thanks. i figured nothing could be done.

FurryNutz:
 ;)

Right.  It's not the log messages that are the issue, it's the fact that the IR light is going on and off per your settings. 

The way motion detection works with these cameras (unless you are using the PIR sensor to detect motion) is that, more or less, the camera analyzes the pixels in the motion detection area (which you set) for changes.  If, to stay general, a bunch of pixels go from white to black (say, because a lamp turned off), this may be a big enough change in the image (depending on the sensitivity settings, which you also set) to trigger an alert.  The camera actually doesn't see "motion", it just sees changes in the image that it is looking at.  If the change is bigger than the threshold you configure the camera for, it decides that must be motion and it alerts you.

That's what is happening when the IR light goes on and off.  The entire image changes from normal spectrum to infrared and vice-versa.  That by definition is a large change in the image, so you'll almost always get an alert (unless your settings are such that it is ignored, but then the camera probably would not ever alert you to anything). 

So, the only way to completely avoid this is to disable the IR lamp completely.  Then the change from ambient dark to light and back will probably be gradual enough (unless, again, there is a lamp going off and on nearby) that the camera will not notice anything, and no alert.  Of course, it won't be able to see in the dark pretty much at all in that case.  That could be OK depending on your needs.  The other possibility is to experiment with setting the sensitivity levels really low and see if that stops the IR motion trigger, but still captures some motion you want to get.  (My guess is that will be a difficult or impossible balance to strike unless your detection area is really small.)
