VIGILAIRE
I spent quite a while writing up solutions to your query, and then pressed the wrong button!!
Please excuse the abbreviated version.
Double check all your settings. The lidl control box takes a bit of getting used to.
Bring folding saw, secateurs and lopping shears to your site. Clear everything that moves in cam line of sight.
What height are you set at ? Remember these cams can be stuck on the side of a building and still work. The pic's in #74 were taking with chest high cam on fence post, slightly below willow branches. I've reset cam 2 foot higher to get better background view and had to do a lot more trimming as a result.
Adjust downward angle of cam by inserting twigs between unit and whatever you are attaching to.
Deer can cover a lot of ground in the 1.2 seconds trigger time. Try to get an angled view of them, and set camera so they are a few yards away. Consider bringing fence post or similar in order to put cam in optimum spot. I put a cam on a field headland looking out and got a lot of blanks because the deer were travelling along the headland too close to cam.
Sod's law says there will be a chorus line of deer passing between shots so consider setting cam to take multiple pic's at shorter intervals. If there is more than one deer then one is bound to walk into view sooner rather than later.
Pick a spot where the deer are likely to stop, even if it is only to look at the camera!
Face cam north or use shade to avoid overexposure from low sun
At this point you have probably tried setting the cam up at home. Once the cam is set for deer avoid the temptation to check it too often. Your scent could spook them. I was lucky that I saw deer before I sited the cam, and the first pic's were less than 24 hours later, but it was 8 days before I went back to check. I have had to wade through 600 plus photos of weanling bullocks before now as a result of staying away but the delete button on the computer helps.
Be patient and you will make your luck.
