I've never explored this type of need before, but love trying to problem solve stuff like this.

Search Amazon for item below. Battery operated with 1/2 mile range. You would have to work with the sensor to set it to alert you when hogs are in the corral. Not expensive at all to give it a try.

A review that sounds applicable

Well, you decide? By Red Ball Jets - November 1, 2012 Amazon Verified Purchase Your level of satisfaction with this product will be based solely on your application. First, let me explain how this product works. This product senses motion between two different temperatures. The outside air and anything warmer or cooler than that air. So, thankfully swaying tree branches do not trigger it. If you're looking to be alerted to humans or animals, this product does that very well. If you're looking to be alerted to vehicles (which is why I bought it) there will be some limitations

Also, trying looking for a wireless swimming pool gate alarm. Similar application to what you're looking for. Distance involved may be an issue though.

Update us on the outcome. I enjoy seeing what solution ultimately solved the problem.

why not just run a doorbell switch with 300-400 feet of light wire from the trap to the cabin. door closes bell rings inside. there are also wireless door bell set ups but have no clue as too range

thanks for the ideas guys. those seem to be viable options. i see a lot of issues created by not running wireless. something like this would be great, but the range (non-destructed line of sight) is only about 250-300. if I could find something like this with more range, that would solve it.
