I think you are over-estimating the capacity of that car battery. You might be able to run a few LED lights for a few hours a day, like 2 or 3 hours a day maybe, but a constant draw of a cheap wifi camera (often not the most efficient possible power-wise), will kill that battery very quickly.
Let's say you wanted to run 12 Watts of LED lighting for 4 hours a day, and a camera (24 hours a day) which draws ~3 Watts.
12 x 4 = 48 Wh. Not much, but definitely substantial.
3 x 24 = 72 Wh. Again, not much, but substantial. This isn't going to be a 10 Watt panel type of deal here. :P
So, 120 Wh total. Or, ~10 Ah.
You'll need to account for cloudy days, so let's multiply that by 3.
360 Wh usable storage capacity needed, and 300 Wh generation needed each day.
You'll only get ~4 hours of good sun in a day, and panels put out ~60% or there about their rated power in the real world.SO...
360 Wh / 4 = 90 Watts.
90 Watts / 0.60 = 150 Watts.
​
So, you'll need:
1 x ~150 Watt rated solar panel. ( https://www.amazon.com/Newpowa-Moncrystalline-Polycrystalline-Efficiency-Module/dp/B00ZIZ6VY6/ should do.)
1 x PWM charge controller. ( https://www.amazon.com/ALLPOWERS-Charger-Controller-Intelligent-Regulator/dp/B01MU0WMGT/ or similar.)
Wire with MC4 connectors. ( https://www.amazon.com/BougeRV-Extension-Female-Connector-Adaptor/dp/B0753ZLLQB/ )
And battery cables to go from the charge controller to the battery, but you can probably buy some ring terminals at your local hardware store and use some 10 AWG stranded copper wire, don't necessarily need to order special ones if you can make them. :)
EDIT: You'll also want to fuse the positive side of the battery, solar, and load circuits. Choose fuse sizing for the wiring you use.
​
Now, the battery will die in a few months most likely if not sooner being cycled like this since it's not a deep cycle battery, but hey, then you can replace it with a good one. :)
