I brought 6 of these cameras and the IQCCTV DVR after watching Colin's video. I was looking on the internet for 2 or 3 megapixel cameras but came across this site selling these 5 megapixel for near enough the same price. I am glad i called them. They have been installed for two weeks now and the image quality is super sharp. The adjustable lens works really well as some cameras needed wide angle coverage and some needed narrow angles so not to pick up the neighbours garden and driveway.
