Dome cameras are small board cameras, mounted on a base
under a clear plastic dome. They are specifically designed
to be mounted on ceilings, although other mounting options
are possible. There are a number of factors to consider
when choosing dome cameras.
One of the first factors to consider
is where the dome cameras are to be mounted. If the
cameras are to be mounted in an exposed outdoor location,
then you need to choose a weatherproof model. Also,
if there are extreme outdoor temperatures in your area
(-10 to + 110 degrees F for color cameras, -10 to +122
degree F for black and white models), then you need
to consider choosing a model that has a built-in fan
and heater.
All of our dome cameras are wired,
rather than wireless, for professional installation
in commercial applications including retail stores,
warehouses and apartment buildings. Wired installation
gives the best possible images with the least amount
of interference.
Another factor to consider when choosing
board cameras is whether to choose color or black and
white cameras. There are advantages to both types. For
example, a color camera can provide 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, a black and white camera can provide
better overall resolution and operate using less available
lighting. Let's examine resolution and low-light operation
a little more closely.
Resolution for dome cameras is usually
specified as the number of horizontal lines the camera
uses to "paint" the image on the display or
recording device. Typical good quality resolutions are
380 lines for color cameras and 420 lines for black
and white models. Low-light operation is usually specified
using the LUX value. Typical LUX values are 1 or .5
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 at night, around
dusk. And .1 LUX is about the amount of light available
in a well-lit parking lot at night. And a camera that
can "see" down to .05 LUX can actually record
an image better than the unaided human eye - enabling
the camera to actually "see in the dark" !
For best overall results, choose one of our dual-mode
day/night models. These models operate in color mode
during the day, and switch to black and white operation
at night when there is less available lighting.
Another factor to consider when choosing
dome cameras is whether or not the cameras will be mounted
in a location that is reachable to burglars or vandals.
If so, then consider one of our special armor dome camers
- these cameras have a vandal-proof plastic dome that
can withstand the impact of a hammer. This is necessary
because burglars or vandals often attempt to disable
any security cameras that they spot. Also, look for
dome cameras that are Plug n Play - these models use
a standard video jack for connections.
