Ultra-Low Light Operation but Hot Pixels and Poor QC for Sensors Used
2007-05-07I 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.

Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
Advantages Of The DV Camcorder
Introduction
The DV camcorder, or digital video camera, has many advantages to offer consumers. Camcorders have come a long way from even the analog camcorder. There are many benefits to using a digital video camera. Some of the advantages that may send you to the store for your own are its compactness, its quality of picture, and its versatility. You can use your digital video camera to transfer your VHS movies to digital tape. You may find that the technology is also much better with a digital video camera.
A camcorder derives its name from its ability to operate as both a camera and a recorder. This electronic piece of equipment has been used by countless families to record baby's first steps, birthday parties, weddings, graduations, etc. These recordings of sights and sounds have provided many hours of family entertainment as well as amusement to television audiences through the capturing of hilarious antics.
