CCTV, What can it do for your Security?
According to the 2002 National Retail Security
Survey report, retail businesses in the US suffered $31 billion
in losses from "Inventory Shrinkage. Inventory Shrinkage includes
employee theft, shoplifting, administrative error, and vendor fraud.
80.2 percent of the total loss was attributed to employee theft and
shoplifting.
There are many CCTV system
applications for residential property as well. These could include a
"video door bell" system, viewing outbuildings, swimming pools, hot
tubs, trampolines, driveways, the nursery, or children's play areas etc.
Keeping track of household employees or services.
One of the most effective deterrents to both
of these risks, is adequate surveillance of warehouses, retail spaces,
point of sale and receiving locations. This surveillance could be
conducted by live guards, however this solution would be very costly and
not nearly as effective as a good quality and properly installed CCTV
system.
CCTV components and
controls have evolved in the last few
years, making quantum leaps in quality, features and capabilities, while
at the same time dropping dramatically in price. As an example, the most
basic DVR (a recording device) would have cost in the 5 digit range just
a few years ago, today modern DVR's cost fractions of those prices and
offer many more functions and features, so much so that VCR recording
devices are quickly becoming obsolete. Viewing your systems from any
computer, via the Internet, or even from your cell phone are both now
available options.
When designing and specifying your system we
need to know a few things about what you want to accomplish;
-
Is your goal to be able it identify people,
or just watch assets?
-
If you are watching assets a black and
white system will probably be fine and with provide higher
resolution and clarity.
-
If you are watching people, and may have
the need to identify them, a color system will be the best choice,
especially if your surveillance could end up in court. Color
identification is almost always required to make a positive Id, a
red shirt for example would show as gray in black and white.
-
When choosing cameras, we need to know
exactly what area you want to see, and what detail within that area
you want to see.
-
Lighting conditions and how they change
throughout the day will determine what kind of camera/lens combination
is needed. If you are watching a dark area, infrared cameras may be
required.
-
How far cameras are located from recording
devices and monitors will dictate what kind a cabling may be needed.
-
How much information you want to archive
will help determine what recording device you will need.
These are just a few of the items that need to
be considered for configuring your CCTV system. Doing it right at the
start will save money and insure that you get the right components.
What about the low cost packaged systems
advertised at "big box retailers"? Here are a few questions to ask.
-
Why is this not the same system the store
uses to watch their own property.
-
Who will service components if needed?
-
What if I need installation help?
