Abstract: An anti-theft device for protection of wildlife surveillance camera systems mounted on a tree includes an external housing fitting over the camera system and substantially enclosing it on all sides. On the front side the housing has a frame overlapping the camera and preventing its removal, while leaving a central portion open to allow viewing by the camera and instruments. The housing has two brackets, one integral with a top side and another one integral with a bottom side of the housing, both brackets at a right angle with the side. The brackets are both bent upward so that the bottom one is underneath the body of the housing and the top one is outside of the body. The brackets are both connected by a lag bolt which is made essentially inaccessible and out of sight. In position underneath the housing, the bottom lag bolt is protected by the housing. The top lag bolt has its head located outside of the housing, but protection is provided by a hub and plug lock denying access.

Abstract: A theft prevention device for fixed-position tree stands employs a horizontal plate with ends bent over to engage a pair of upright supports of the tree stand. The plate has a hole at a central location through which a lag bolt extends, securing the plate to a tree. Barriers to access to the bolt along its length and at the bolt head are provided. A barrier underneath the plate takes the form of side plates connected to edges of both sides of the horizontal plate or a hub surrounding the bolt. An outside barrier protecting the bolt head is provided by a hub and a plug lock engaged with the hub.
