How do I build a long range motion detector?

I am interested in building a motion detector with an alarm that reaches approximately 200 yards from my house. I have a bait station set up to attract coyotes and want to be alerted during the night when they show. In the past I have installed security systems but have limited knowledge of circuitry and am interested in a relatively simple set up. I was picturing a wired system and am interested in hearing some options.

200 yards will be hard to achieve. A local alarm and some long wires will work better.

Why does it have to be long range when you can set it up at your bait station? What is the objective of the station? What good is getting an alert? You could set up a game camera that will snap pictures when they show up.
