INSTALLATION

Site Survey

Before installing the MiniBox-4, you should conduct

a physical survey of the site where the unit is to be

installed. The purpose of the survey is to determine

the proper height and position of the unit relative to

the primary subject to be observed. You should also

consider 110 VAC power availability (and cable or DSL

availability if applicable).

Determining the optimum position for the MiniBox-

4 involves several considerations including the focal

length of the lens, the upper and lower limits of travel,

and the distance between the mounting site and the

object under surveillance.

For rule-of-thumb purposes, you might think of the

viewable area this way for a reasonable approximation:

At 10 feet high the blind spot on the ground will be

approximately 10 feet inward and the viewable width

will be approximately 10 feet out. At 20 feet high the

blind spot on the ground will be approximately 20 feet

inward and the viewable width will be approximately 20

feet out.

Items outside of the Utility Box’s viewable limits will

not be visible. See the example at left. A subject close to

the bottom of the pole would not be visible to the Utility

Box. You should set-up and test the Utility Box at an

alternate site but under similar conditions in advance

of your mission. This is the best way to ensure that you

will know what to expect once you have deployed the

Utility Box at the actual surveillance site.
