4-6.7
Cost Considerations. The obvious primary cost considerations are the
number of cameras, mounting devices, and the associated wiring. Adding more
cameras will increase the personnel burden required for monitoring those cameras. This
can be alleviated by the proper design of a monitoring system. If cameras are not
monitored, their data should be recorded and stored for use as after-the-fact evidence.
As discussed in the System Displays Section, larger plasma panels or flat screen
displays can be configured to show only cameras that display alarm conditions.
4-6.7.1 Effect on maintenance costs. In general, more cameras and more
monitoring systems are going to result in higher maintenance costs.
4-6.7.2 Order of magnitude cost estimates. While there will be variations with
actual installed constructed cost across the United States based on labor type (union or
nonunion) and labor supply, the following general rules of thumb can be used for
conceptual cost estimating:
4-6.7.3
Interior fixed camera: ,100
4-6.7.4
Interior speed dome camera: ,800
4-6.7.5
Exterior fixed camera with heating equipment: ,600
4-6.7.6
Exterior, pan-tilt-zoom camera: ,600

INTERNET PROTOCOL (IP) ADDRESSABLE CAMERAS
4-7.1
An IP camera captures a video image digitally. The video encoder protocols
have not been standardized within the security industry and therefore these cameras
require up-front care in specifying the correct protocol and viewing software.
4-7.2
Typical System Configuration. The IP camera resides on a local area
network (LAN). Video data is transmitted via the LAN to a video server that routes the
video to end-users and possible mass storage devices (storage server).
4-7.3
Pros and Cons. IP cameras are the least secure CCTV system, but may
have application where remote viewing over a network is desired, or where a high-
bandwidth network may exist. For example, with a typical matrix switcher configuration,
in order to view camera images at a site distant from the actual matrix switcher location,
new cabling must be run between the matrix switcher and the remote site. With an IP
camera system, a network connection between the sites is all that is required to view
any camera image on the system. One drawback to IP cameras is that they cost more
than a standard analog (non-IP) camera. Due to the security concerns with the internet,
IP cameras will generally not be used on DoD projects. The possible exception would
be CCTV surveillance of low priority assets at remote locations.
