I don't know about that patio. I'm a good industrial machine mechanic / electrician, but I think I would have more than $29.95 in materials alone if I built a camera housing unit with heater / blower like the one I linked, not to mention my time, which is limited these days working 6 and 7 days a week. And I have plenty of 24vdc power supplies available so that won't be any additional cost ("Power Supply: Sold Separately'), in my case. I just need a camera that will fit correctly and last a little longer than 6 months.
