just waiting for costs to go down even more before attempting this worthy data collection project. Right now there are units you can stick a SIM card in and basically makes it a mobile phone, you can use GPS real time and have the unit text you when its outside set perimeters. You can also call the unit and listen to sounds. No camera though and expensive + needs cell service sub.

Soon, though. I will know all their secrets.

cant find the little unit you can call.. i remember it because of the size.. most pet trackers are dog sized for hunting dogs, etc.
