My favorite for the lower level back patio is a Speco CVC-7700DN which has IR leds for night time. The camera gives a great picture in all lighting conditions. Highly recommended.
I have a Pelco Spectra II PTZ for the front of the house, but it can also look over the roofline to the east side. Excellent daytime images, not real great at night - but there is little light available. I'm planning to install an IR source, which I hope will improve it.
