I have this set up and it has worked for me.I have the foal alert system, and yes they work, but be aware if they just lay down for a little nap the beeper will still go off! I used this system for two years by itself, then decided that running to the barn everytime it went off was a pain, and I ran the risk of actually stopping labor by disrupting things. So I installed a camera system, and using the two together works great. The beeper will wake me, and I can check the mares without disrupting them, OR running to the barn!
