I go about this a little differently. I don't try to find a buck's bed, because if I do find it, he will likely move once he has been found. I just like to hunt at places that appear to be the best opportunities for a shot, with the intention of never getting close enough to his bedding to spook him.
All of my cameras are out in the open, and I never put one close to bedding. It doesn't bother me if all of the pictures are nighttime unless all of them are in the middle of the night. If they are, he is probably bedding far away on another property. If that's the case, there's not much you can do in the short term to change that. For the long term, you might try to improve bedding opportunities on your land.
That's a good looking deer. I wish you the best with him in the future.
PS - The deer I killed this year was on camera over 2 miles from my property 4 days before I shot him. Hard to say how many beds that deer had.
