Hi, I would love if someone could help me. I own a mobile food vending business here in NYC. I currently have a security system with 4 cameras. I am on the AT&T network. I know they have a I2Gold Plan for 3$ a month that locks the IP address. During my season we are on the streets 7 days a week almost 14 hour days. I really need some help if anyone could tell me what I have to do or how to set it up. I use a night owl DVR with 4 cameras on it. 3 watching the outside and 1 on the inside over my draw. If anyone could help me please. Thank you. Andrew
