Our camers are green and DH attaches them to a sturdy tree with bugee cords. They are motion detected and he tries to place them where there are not too many branches that move with the wind. They take very good pictures and we take out the SD card and place it into the printer which then sends them to my laptop.
We are not using them to observe wild life...they are just to check for thieves and trespassers! We get pictures of our cats walking through our property and the occasional fox. They snap a series of 3 pictures at a time and will take them in daylight or darkness.
The cameras are very hard to see, unless you are looking for them. The man and woman that we turned over to LE did not even notice them. We had printed out copies of the pics for the LE's and they took the SD cards for evidence. My son is a hunter and he has one at his hunting cabin to see how many deer come on his land to feed. I have a feeling that is what the hunters in Texas use them for.
Hope that explains their use to you.
DEAR GOD...PLEASE BRING HAILEY HOME ALIVE!!
