3)
Very Low-Light Cameras.  Very low-light level cameras are also
available. Such cameras can function at 2 x 10E-5 lumens per square meter.
Very low-light level cameras find application where "blackout" conditions are
to be maintained at a facility.  Such cameras use Silicon Intensifier Target
or Intensified Silicon Intensifier Target tubes.  These cameras are
expensive, roughly 20 to 30 times the cost of a standard video camera.  As a
result, it may be more cost-effective to upgrade lighting than to use such
tubes.  Designers may encounter applications where such cameras fulfill a
special requirement.
4)
Solid-State Cameras.  These cameras use charge-coupled solid-
state devices that function like the vidicon tube of a conventional camera.
Elimination of the tube increases reliability and minimizes maintenance
requirements.  Its small size and high reliability are very desirable
features.
4.6.4.2
CCTV Monitors.  Monitors are devices upon which a CCTV scene is
projected and viewed.  For access control monitoring, a 19-inch (0.5-m)
monitor is preferred.  A 9-inch (0.3-m) monitor is typically used for
security alarm assessment.  One operator can effectively handle up to eight
monitors (four sets of two stacked vertically).  It is desirable that
monitors for alarm assessment remain blank until an alarm occurs.  If the
system is also being used for surveillance of an area when an alarm occurs,
the alarmed zone scene should automatically replace the surveillance scene.

Exterior Security Lighting
4.7.1
Introduction.  This section summarizes the kinds of lighting
deployed to enhance the security of DoD facilities.  Specifications are
provided for both direct guard-visual and CCTV surveillance.
Function and Location.  Security lighting aids threat detection,
4.7.2
assessment, and interdiction.  Lighting may also have value as a deterrent.
Security lighting increases the effectiveness of guards and CCTV by
increasing the visual range during periods of darkness or by illuminating an
area where natural light is insufficient.  Exterior security lighting is
typically located along exterior perimeters and entry points of the site and
buildings. Each facility presents its particular deployment problems based on
physical layout, terrain, weather conditions, and security requirements.  The
remainder of this section discusses standard types of lighting, lighting
concepts, lighting for CCTV, and surveillance and related lighting issues
(energy and legal).
4.7.3
Standard Exterior Lighting Configurations.
Lighting may operate
continuously or on a standby basis.
4.7.3.1
Continuous Lighting.  Continuous lighting (the stationary
luminaire) is the most common security lighting system.  It consists of a
series of fixed luminaires arranged to flood a given area continuously during
