5.2 Field Of View 

A

 

proper

 

"Field

 

Of

 

View"

 

(FOV)

 

is

 

crucial

 

for

 

optimal

 

Vantage

 

system

 

operation.

 

The

 

following

 

basic

 

FOV

 

guidelines

 

will

 

help

 

the

 

user

 

to

 

obtain

 

optimal

 

Vantage

 

system

 

performance.

 

There

 

are

 

two

 

parts

 

to

 

obtaining

 

an

 

appropriate

 

FOV:

 

 

Physical

 

camera

 

mounting

 

adjustment

 

 

Electronic

 

camera

 

lens

 

adjustment

 

5.2.1 Physical Camera Adjustment 

The

 

camera

 

should

 

be

 

mounted

 

so

 

that

 

it

 

is

 

centered,

 

as

 

much

 

as

 

possible,

 

in

 

relation

 

to

 

the

 

field

 

of

 

view

 

(vehicle

 

approach).

 

Extreme

 

side

 

shooting

 

can

 

result

 

in

 

reduced

 

performance

 

and

 

vehicle

 

occlusion.

 

See

 

the

 

section

 

in

 

this

 

manual

 

on

 

"Occlusion"

information.

Proper Mounting Height 

The

 

camera

 

should

 

be

 

mounted

 

at

 

approximately

 

30

 

feet

 

for

 

optimal

 

system

 

performance.

 

For

 

lower

 

mountings,

 

like

 

a

 

mast

 

arm

 

mount,

 

a

 

suitable

 

camera

 

extension

 

bracket

 

should

 

be

 

used

 

to

 

increase

 

the

 

camera

 

mounting

 

height

 

to

 

a

 

more

 

workable

 

elevation.

 

A

 

camera

 

mounting

 

height

 

of

 

25

 

feet

 

or

 

more

 

can

 

usually

 

be

 

obtained

 

by

 

using

 

an

 

extension

 

bracket.

 

Low

 

mounting

 

heights

 

can

 

result

 

in

 

reduced

 

system

 

performance

 

and

 

vehicle

 

occlusion.

 

See

 

the

 

section

 

in

 

this

 

manual

 

on

 

"Occlusion"

 

for

 

more

 

information.

 

How

 

far

 

can

 

the

 

camera

 

typically

 

see

 

out

 

at

 

a

 

mounting

 

height

 

of

 

30

 

feet?

 

The

 

basic

 

formula

 

for

 

LEVEL

 

ground

 

is:

 

For

 

every

 

one

 

foot

 

of

 

height

 

you

 

can

 

see

 

out

 

10

 

feet.

 

So,

 

on

 

level

 

ground,

 

at

 

a

 

30

 

foot

 

mounting

 

height,

 

you

 

should

 

be

 

able

 

to

 

get

 

accurate

 

detection

 

as

 

far

 

as

 

three

 

hundred

 

feet.

 

This

 

measurement

 

is

 

from

 

the

 

camera

 

mounting

 

location,

 

not

 

from

 

the

 

intersection

 

stop

 

bar

 

area.
