A trail camera having one or more hinges to provide pivoting of the trail camera after mounting to a fixed object is disclosed. The sensor device include a support structure, a sensing element mounted on the support substrate for sensing optical radiation and generating an electrical output signal in response thereto, and an encapsulant encapsulating the sensing element on the support structure. The transporting pump may alternatively be provided between the first compartment and the solution tank. The safety guardrail also comprises one or more four-walled non-linear diverters defining a path between an open anterior end and open posterior end, the one or more diverters connected to the one or more support plates. The path average dispersion of the transmission line portion is: D=D1S2-D2S1S2-S1. The device comprises a transportable chassis, a reservoir and hollow dispensing tines.
