This will depend on your individual situation and feel free to message us to make sure you're getting the right pledge. Essentially, you would choose one "base" reward and then add on another package depending on the number of cameras and base stations you're looking for (plus any applicable shipping).
Typical add-ons are as follows: $135 for each additional Home Cam (no Base Station), $45 for each VAVA Solar Panel, $7 for each additional Home Cam cover. You also have the option of adding a Dash Cam as a supporting reward for $149.
For example, if you had an Early Bird Duo ($289 - 2 Home Cams + 1 Base Station) -- but you wanted 3 Home Cams but 2 Base Stations, you would add on the Early Bird Home Cam reward ($159), plus an additional $10 for shipping (half of what it would have been for the individual Early Bird reward).
