L series home can be used as a home but its designed to be cellular, you need an active plan to access many of the settings , time date , hi res images etc - if you dont wan ot run it that way, you can buy a monthly plan, set everything the way you want it and cancel the plan, in that respect it will cost you $15 to set everything up the way you want it but then its done. The other option is to make one of your remote cameras the home in link menu, then you can set the time on that unit and the rest will sync to it and it wont cost you anything, if you plug the L cell home into it the remainder will sync to its time and it wont be correct . the L home units are sold at a loss with the idea the cell plan will help pay for the cost since it has a cell modem and a link radio in it but retails for the same as the remote cameras.
