Reolink PoE 4MP HD Indoor/Outdoor Surveillance Camera, Night Vision/Audion/Remote Access/Motion Detection. RLC-410 $54.99 Amazon (purchased 1 to start, but will immediately buy more after seeing how great these are and how easy it is to setup!)

Purchased CAT6 (GET ROUND CABLES/NOT FLAT CABLES!) PoE cabling 150ft to milkroom plus multiple 5-7ft sections for connections between Switch & Camera's. About $35 for all the cabling
Purchased NetGear 5-Port Gigabit Ethernet Switch (GS305P), installed in the milk, via 150ft CAT6 cable from home to barn. $59.99
SUPER EASY SETUP!!! Just plugged in the CAT6 from my router to the NetGear switch, from the NetGear Switch to the ReoLink Camera, downloaded the Reolink App on my iphone and setup an account. Poof everything works GREAT!! Plus it has some seriously awesome night vision! I forgot to turn on the lights the first night, but when I checked the camera feed it was great! No additional like was necessary! Pic is nice and clear and I can tell every animal even in the pitch black!
* NOTE: REMOVE THE MOTION DETECTION because it seriously screeches out alarms like crazy and send notices!! Ugh! For some reason I do have to unclick the audio Mute every time I check it on my phone. Not sure why??
