Been seeing this item advertise for the last month or so, so finally got around and contacted SPYPOINT via email......They said it works off of VERIZON or AT&T your choice, it will work with almost any camera all cameras, I asked about my model a Moultrie 888i and they YES it will work. Release date will be June 15th, I placed a Pre-Order from B&H Photo, with tax just under $64.00 FREE SHIPPING.....
