So why do I get them all night long and the first hours of daylight and last hours of daylight, but not midday?
I don't know the main reasons why you don't, other than cam placements, and where placed, less deer movement during midday.
My main point is that, contrary to popular thought, deer, particularly mature bucks, do in fact move around quite a bit during mid-day . . . . . . generally speaking. However, outside heavier cover, they are more likely to flat out run from Point A to Point B, which can result in triggering a cam, yet the cam has no deer pic (or maybe just the blurry butt end of a deer).
As to trail cams not picking up mid-day deer, I stand by the earlier statement that our cams are less sensitive during mid-day (no matter how you have them set). Worse, we tend to get more false triggerings during mid-day from wind & sun, which then can cause us to miss a deer while the cam is "down" for a few seconds to a few minutes (typically).
If you set your cam for a 30-second delay between triggering events, that cam may be non-functional for a full minute from a false triggering event. Those false triggering events generally don't happen at night, nor much during early morning or late evening.
I've never - NEVER - seen a deer walk near one of my trail-cams and not get their picture taken. I've never - NEVER - walked near a trail-cam and not gotten my picture taken.
TOUCHÉ . . . . . The BSK
Obviously, you have -
NEVER - used a Tactacam -
NEVER, EVER.
Stick with those Brownings, and you'll never feel our pain
