TECH TIPS: CO-RELATION OF IR CORRECTED LENS WITH FOCUS AT
DAY/NIGH WITH INFRA RED LIGHT
TECH TIPS: CO-RELATION OF IR CORRECTED LENS WITH FOCUS AT
DAY/NIGH WITH INFRA RED LIGHT
Summary to sum up the above, there are two situations where IR corrected lenses should be
preferred:
1.When the illumination changes between visible and infrared light, e.g. from daylight to IR illumination,
from halogen to fluorescent, or from daylight to high pressure sodium or mercury lamps.
2.When using light composed of a mixture of visible light and IR light, such as sunlight, halogen or
ordinary incandescent light bulbs.
The above is valid when using monochrome or day/night cameras only. When using color cameras,
which are not IR sensitive, the advantage of using IR corrected lenses is limited to being color-
corrected as well, resulting in a slight improvement of the picture quality. It is not possible to modify
standard lenses to make them IR corrected, e.g. just by coating the lens elements – at least not with
optimum results. From the early stages of the design phase IR correction must be considered and
included in the design, special glass must be used for the lens elements and special coating of the lens
element surfaces is required. Previously, this caused IR corrected to be fairly expensive, but new
efficient production technologies have reduced costs dramatically.

The coaxial cable is the most common medium for transmission of video signals and
sometimes video and PTZ data together. It is also known as unbalanced transmission, which comes from
the concept of the coaxial cable ( sometimes called “coax” for short ).A cross section of a coax is shown
above. It is a symmetrical and coaxial construction.
The video signal travels through the center core, while the shield is used to common the
ground potential of the end devices - the camera and the monitor, for example It not only commons the
ground potential, but also serves to protect the center core from external and unwanted electromagnetic
interference ( EMI ). The idea behind the coaxial concept is to have all the unwanted EMI induced in the
shield only. When this is properly grounded, it will discharge the induced noise through the grounds at the
camera and monitor ends. Electrically, the coaxial cable closes the circuit between the source and the
receiver, where the coax core is the signal wire, while the shield is the grounding one. That is why it is called
an unbalanced transmission.

TECHNICAL TIPSTECHNICAL TIPS
If you have a choice of crimping connectors, look for the ones that are likely to last longer
in respect to physical use and corrosion, like silver plated or gold plated BNCs. A good practice would
use “Rubber sleeves” (sometimes called “protective sleeves” ) for further protection of the interior of
the BNC from corrosion and to minimize bending stress by plugging and unplugging.

CARE AND FEED YOUR CCTV INSTALLATION CARE AND FEED YOUR CCTV INSTALLATION
Congratulations on the installation of your new Closed Circuit Television (CCTV) Security
System. It has been installed, tested, and is up and running. What now? What steps do you take to get
the best performance and results from your investment? Does it require any maintenance? How will
you know there is a problem before it's too late and important information has been lost forever? Here
are some tips and guidelines to keep your system operating at peak performance:
CCTV IS NOT LIKE YOUR HOME TV SET.
Besides no commercials, this means many things. For one, it is designed for continuous long-term use. The
components are built to completely different standards.
As an example, commercial broadcast video (TV) uses cameras that cost thousands of dollars, and are not
practical for security use. There are a great variety of cameras for the security market, with many different
uses and features. Most are of high quality and will provide good performance. But they are often installed
in locations that can make them susceptible to outside forces; even simple things like cleaning the lenses
occasionally may be necessary, particularly if they are installed outdoors. The monitor operates differently
from your TV too. It does not receive radio broadcasts, but rather gets its signal directly through a cable
(coax or S-Video, not ESPN or HBO). A normal television can be used as a security monitor, but will usually
have to be replaced 2 or 3 times in the life of one security monitor.
BE AWARE THAT CONDITIONS CHANGE.
All the components of your CCTV system are designed to specific international standards, and are
interdependent on each other for proper operation. Things that affect one component may affect the
performance of an entire CCTV system over time. During wet weather, for instance, your system may be
much more prone to ground loops, which can play havoc with the quality of the video. Simple things like
cables and connectors can deteriorate as they get older. Cables and connectors are often overlooked, and
yet as their age, are capable of causing problems for the entire system. If in doubt, call the installing
company for an inspection.
