Trip wires for bear

[Nuts]

I have been investigating using trip wires with alarms to place around meat or late day kills in AK for bear protection. Knowing from a distance something is messing with things would be helpful besides scaring them off. I am not a fan of the 209 primer or 12gauge ones unless its in front of a buddies tent after he goes to bed. Its once and done as a detergent and the audible alarm keeps going. Has any one used these? Any recommendations.
