GENERAL
INFORMATION
Many years ago
there were only about five types of Cameras available in the security systems market. Today
things have changed considerably. At one time there were only tube
security cameras. Today all of the cameras we use
for closed circuit television (CCTV) use a special
computer chip called a CCD. These cameras are a lot more dependable
than their tube counterparts, and produce a much better picture.
These chip Cameras are much less expensive to
produce as well. All of these factors have made the use of CCTV much
more affordable and practical for a wider variety of applications
than ever before.
Lenses
The lens of a camera is like the cornea of your eye. Without it you can
not see, and neither can the camera. There are many
different types of security lenses in the security camera market.
The first division between lenses are the wide angle and the zoom
lens. The next division is between the auto iris, manual iris, or no
iris at all. These choices and others depend on the intended use of
your security camera system. Correct camera lens choice should be
determined with your CCTV technician
There are many factors
involved in choosing suitable lenses for your Cameras are given on
the CCTV Camera
Lenses.
Security Camera Resolution
Camera resolution is a measurement of the cameras clarity. The resolution is determined by the number of horizontal video lines (like 400 or 430 lines) that the camera needs in order to reproduce the desired image. The higher the resolution number, the sharper the image will be. Although resolution is important when considering which camera to purchase, the quality of the cameras components is much MORE important. We only sell high resolution, name brand, quality Cameras.
LUX How it affects picture quality
Lux (1/10 of a foot candle) is a standardized method by which to measure a camera's sensitivity to light. The lower the number, the less light it will take to reproduce a clear image. For example: A camera that sees down to 1 LUX, means it generally has the ability to see an image during early evening hours or just before dusk. A security camera that's down to .1 has the ability to see an image in let's say, a well lit parking lot. A rating of .05, the ability to clearly view an image in a dimly lit area at night. A .05 image can usually enable a camera to actually see better than the human eye at night!
