I researched RFID tags , but can't use locator to find the stolen item. I looked at GPS tracking, but they need batteries changed frequently, and a monthly fee to be paid like a cell phone bill, any ideas would be greatly appreciated. This set back will eat up two years profit. We have to find a way to catch these thieves. I have in the past hooked up cameras and paid for wifi until the house sold or rented, but setting  up and then cancelling the service was very expensive too. HELP.
