Hi my mare is due to foal in a month too and we got this camera. http://www.pcworld.co.uk/gbuk/netwo...7774!&ef_id=VSw7jQAAAbSELBHJ:20150413215629:s We wanted a couple of others for about the place so it made sense to get four. Two in stable do we can see each side of her and two for else where.
They work great and even with the lights off I can see everything going on in her stable, inc dust floating about! 😳
Good luck 🍀
Look at infra red cctv cameras on ebay and there are complete setups on there that are a lot cheaper than the ones that say foaling since anything related to horses seems to have a few hundred £ added to the price. if you want wireless you may need to provide a sim card as well but thats easy to do
