My shealth cam (MC1-DRT2) came with a lock plate that is fed thru where the strap goes and the bar has hole on each end to pass a chain thru so you can chain it to the tree. However, if they find the camera and they are the type of person who would steal it no lock or chain is going to stop them. I don't know if all Shealth cam come with the lock plate but it is my guess they do. Here is their phone # 1 877 269 8490 if you want to call them.
