Choosing the right video
surveillance system
Choosing the right video surveillance
system can be a daunting task. One of the ways to simplify
the process is to choose one of our complete systems.
These systems assemble all of the parts and pieces that
you need for a complete video surveillance solution.
There are a number of factors to consider when choosing
a system.
One of the first things to consider
is whether to choose a wired or wireless video surveillance
system. A wired system can transmit the video signal
over greater distances, with less signal interference
than a wireless system. On the other hand, a wireless
system is much easier to install, since you do not have
to run all of the video cabling. A wired system will
cost less than a wireless system, but this cost savings
can be easily overcome because of labor costs for installation.
Generally speaking, a wireless system can be used in
situations where the distance between the cameras and
the display or recording device is less than several
hundred feet.
The next factor you will need to consider
when purchasing a video surveillance system is the number
and type of cameras to use. Systems are available with
4, 8 and 16 cameras. Cameras can be color or black and
white. There are advantages to both types. Color cameras
furnish more information about the subject of the image,
such as the color of a person's clothing or the color
of an automobile. On the other hand, black and white
cameras furnish more detail (have a higher resolution)
and can operate with less available lighting. Let's
look a bit more closely at resolution and low-light
operation.
Resolution for video surveillance systems
is typically specified as the number of horizontal lines
the cameras use to "paint" the image. Typical
resolutions are 380 lines for color cameras and 420
lines for black and white models. Low-light operation
is typically specified using the LUX value. Typical
values are 1 LUX for color cameras and .05 LUX for black
and white models. By way of comparison, 1 LUX is about
the amount of light available late in the evening, around
dusk. And .1 LUX is about the amount of light in a well-lit
parking lot at night. And a camera that can "see"
down to .05 LUX can actually record images better than
the unaided human eye.
Another factor to consider when purchasing
a video surveillance system is the type of recording
device used. VHS recorders are already a thing of the
past, with state-of-the-art DVRs (Digital Video Recorders)
now being the norm. There are two types of DVRs available
- standalone and PC-based. The standalone types have
a built-in display and hard drive all in one unit. The
PC-based units have a DVR card in them, with software
used to turn the PC into a DVR. Look for the ability
to view your images over the internet when choosing
a DVR - this will allow you to view your site from literally
anywhere in the world where you can log on to an internet
PC.
As you can see, there are quite a few
things to consider when choosing a video surveillance
