Get a good face shot!
Use Higher quality cameras at entry areas Doors, gates and other
entry areas need a good quality, high resolution camera to
record a good 'face shot.' The video from this camera should be
considered a highly valuable since it can be used as evidence in
identifying a person in a court of law.
Wide Angle Cameras for large surveillance areas
Once you can get a good shot of a persons face, you should use a
wider angle camera lens for the interior surveillance spaces of
the building. Using color cameras inside your building is a good
idea because you can readily identify a person by the clothes
they are wearing. Used in conjunction with the face shot at the
entry point, you have an excellent record of all people and
activities in your surveillance areas.

at less than $80 and good color cams start at $150. When it
comes to budgets, having a low cost black & white camera is
better than no camera at all.
Black and white cameras have advantages over color security
Most B/W cameras can see in lower light and have higher
resolution than color cameras. If most of your surveillance
goals are at night and your budget is limited, a black & white
camera may actually be your best solution.
Professional and Standard C-Mount Cameras
If your budget permits, a c-mount camera, which is more commonly
referred to as a
standard body camera
, can offer a big advantage
over other cctv cameras.
C-Mount or CS-Mount?

real difference is the way the lens mounts to the camera. And
that's not a problem since the adapter to convert 'C-Mount' to
'CS-Mount' comes with the camera. This enables the camera to use
either C-Mount or CS-Mount lenses.

C-Mount cameras can use a varifocal lens. This is a huge
advantage because you can adjust zoom and focus. With Varifocal
lenses the focus can be varied from 5mm to 20mm or more.
Even after installed, the varifocal camera lens can be adjusted
to choose a variety of focal distances and angles of view. An
example of where you might use a varifocal lens is outside (or
inside) a warehouse or parking lot where you need more distance
than 35 feet.

and zoom in on anything or anybody within the sight of the lens.

look at. The duration that the camera looks at a given set point
can be adjusted from less than a second to as long as you would
