First camera works well. tracking doesn't seem to follow all the way. Also the chat help on the app doesn't work at all. It won't answer even the basic questions they provide as thier own suggested questions and doesn't recognize your email as valid ever so you can't email them either. I can't figure out for the life of me how to add a 2nd camera. and you have to pay the monthly subscription to have a 2nd camera which is ridiculous. I bought internal SD cards to avoid a monthly fee.
