motion on flood light vrs spotlight cam

We purchased a spotlight cam battery and and a floodlight cam hard wired. The flood ight cam I am able to adjust the motion using a box like adjustment that works really well. I am having trouble adujusting the spotlight cam. I have it on the front of the house and it is going off for every car that dvies by. When I pull back the motion on the 3 sections ( it will not allow me to adujust one that I can see) then it no longer covers my walk way. Any suggestions. Do any of the other cameras have the adujustmen that the floodlight camera has but a battery camera as I don't have electicity where it is located.
