The camera is small indeed. I installed it inside "CURT Manufacturing 22750 2 In. Black Steel Tube Cover" on the towing receiver. It is well protected there from vandals, bad drivers and environment. The resolution and picture quality is perfect for 800x480 radio (Planet Audio P9640B).
The wide angle (170 degree) is only in horizontal view - vertical it seems less. I tilted the camera just a bit down, so I could see the road about 1ft behind the rear bumper. and the same distance behind each corner.
The guide lines are drawing the area narrower than my Tacoma, I will have to add about 1 ft on each side to make the width of my truck.
Standard backup lights are giving enough light for the camera to see what's behind. The low light picture is a little grainy, but still better from many C-MOS cameras you can buy.
Overall I'm happy.
Update: September 17, 2016
It's about 2 years after the installation. For all that time the camera lenses were exposed to environment: rain, dust, direct sunlight. Now the image is foggy. Not that there is a moisture or scratch on lens itself, but looks like lens material changed it's structure. It became kind of yellowish and a bit foggy under the surface. The image sensor still works great just lens is not that good. Now when the sun is behind the car the screen shows all foggy yellowish white nothing. So I took two stars for durability (I added them back as the issue was not with the camera).
I'm had replaced it with the new camera, and I will see if they got better quality lenses after two years. Yes, I got the the same camera as it is hard to beat the price and image sensor quality in all light conditions.
Pictures show the installation location and the initial quality of the image on car's radio. I show also comparison between lens of the old and new camera as well as the comparison of the same image shown by old and new camera.

I analyzed the old camera. Here are my findings:
1. The camera was very well sealed from both ends with some kind of black silicone. There is no sign of any moisture inside.
2. The imaging chip is clear, as well as a glass shield protecting the chip. No signs of any moisture or damage.
3. The inner side of lenses is clear, free of moisture or any damages.
4. The lenses from outside shows extreme damages. The UV protection layer is gone, the glass itself (yes the lens is glass, not plastic) has mechanically damaged surface. Probably from dust, grain of sand or rocks. The indents in the surface are so deep, that cannot be polished.
My Conclusions:
1. The camera experienced a lot of mechanical abuse. The may it was mounted was the main factor in it. Even when the camera was facing to the back of the car, the dust and sand from under the car picked up by the turbulent air was thrown at the camera lenses.
2. Despite this abuse the camera held up very well. Only exposed lens surface was damaged, no other internal damages at all.
3. I would recommend this camera to anyone with warning to treat is as a camera, not a bumper. It is delicate optical instrument and I would recommend to install it in the place protected from direct mechanical abuse. Especially the lens should be protected. For example if mounted as a front facing camera it should be mounted behind some kind of glass screen that is easy to clean or replace if damaged.
See the images attached comparing the lenses of the new camera with the old one. I also included images of the "guts" of the old camera showing that it is in perfect condition.
