So you could look at a premier Elite 24 and smart com, or a any hard wired panel that has 5 zones available and has a coms module which can be hard wired or wireless, if hard wired you may want a vonets wireless bridge or similar to use wifi.
The question is do you see yourself having sheds or other areas, like driveway covered in the future, in which case consideration maybe to have an Elite 48 instead of a 24 so you can separate the areas out.
Elite 24 has two areas so the house could be Area A and Garage Area B, although you could have them as A and B as they are joined together and then have Area B spare for sheds or the drive.
Price wise, an Elite 64W kit might work out better, the issue here is only 4 hard wired zones, so if you are using the hardwired keypad kit 086, then you could use the 2 zones on the back of the keypad, which would cover your hard wired zones you already have without any extra expense (ie hardwired expander).
The smart com for remote access and that has hard wired and wifi options built in.
