Ultra-Low Light Operation but Hot Pixels and Poor QC for Sensors Used

I bought two of these in March 2006 for a simple home security system. Both provide exceptional low-light amplification with very little noise. You can almost see in the dark with no need for IR or other illuminators. Both units appear to be very well made and come with power supply, video cable adaptors and a rugged adjustable mounting bracket and aluminum sunshade. They appear to be very high quality on the exterior.

However, one of the units has a very bright dot (actually a tight group of hot pixels) near the top center and a less bright group of pixels just left of center. The other unit has no hot pixels. Hot pixels would be unacceptable to me in a camera used to record precious memories. But for a security system, it is not a show stopper. Getting clear images in all light levels is what's most needed.

I just recently purchased a third unit and found that it too has a couple of hot pixels in the image. Much worse, this third camera also has a very grainy unusable image under even moderately low-light. Poor low-light performance is unacceptable. So, it is on the way back to Amazon for an exchange.

In summary, I've received one perfect sample out of three thus far. Two samples have hot pixels, which may or may not be a big issue, and one sample had much worse low-light image quality. It appears that Lorex has poor QC in checking image quality for these cameras.
