real-time.

Since

the

cameras

are

temporary,

the builder

can

re-use

the

cameras

at

other

neW

construction

site,

decreasing

the

initial

investment

for

a

total

security

system

to

cover

all

construction

projects.

Mobile

Transportation

[0054]

Without

proper

measures,

public

transit

vehicles,

school

buses,

light

rail

cars,

and

trains

can

be

affected

by

security issues

involving

passengers

and

operators.

Problems

such

as

vandalism,

assault

and

even

suspicious

liability

claims

can

affect

or

disrupt

an

operation.

While

there

are

mobile

surveillance

systems,

they

require

an

on-board

DVR

Which

can

be

cumbersome

and

dif?cult

to

retro?t

into

an

existing

transportation

vehicle.

In

addition,

the

existing

sys

tem

may

not

provide

real-time

information

to

a

central

moni

toring

station.

The

Wireless

netWork

camera

systems

described

herein

can

alleviate

this

problem

With

a

loW

instal

lation

cost,

and

very

little

additional

equipment

to

install.

[0055]

With

protected

dome

cameras

at

multiple

locations

on

the

transportation

vehicle,

a

broad

coverage

can

be

enabled,

While

providing

an

avenue

for

central

monitoring

through

a

3G

IP

based

data

netWork.

The

base

station

can

store

images

temporarily

should

an

interruption

occur

through

the

3G

netWork

preventing

immediately

transfer

of

images.

With

the

temporary

storage

at

the

base

station,

a

near

real-time

video

security

monitoring

can

still

be

obtained

With

a

very

cost

effective

system.

Video

recording

can

be

done

at

the

central

location,

providing

the

bene?ts

of

immediate

access

to

security

of?cials,

elimination

of

daily

video

transfer

for

historical

recordkeeping

and

leveraging

loWer

storage

costs

at

the

central

facility.

[0056]

Military

and

Border

Patrol

[0057]

In

a

War

Zone,

there

is

no

time

and

too

much

risk

to

install

video

surveillance

systems.

In

terms

of

security,

there

is

no

greater

need

than

in

military

applications

for

quick,

reliable

and

secure

mobile

video

security

systems

that

can

be

centrally

monitored.

Lives

can

be

saved

in

identifying

rogue

activity

and

quickly

responding

to

potentially

dangerous

sce

narios

before

an

enemy

can

act.

In

most

regions

of

interest,

there

is

no

poWer

availability

and

the

lack

of

a

surveillance

capability

can be

detrimental

to

securing

the

perimeter.

If

a

security

threat

cannot

be

identi?ed

and

responded

to

before

it

is

too

late,

then

the

effort

for

enforcing

barriers

and

prevent

ing

unauthorized

access

can

be

severely

hampered.

Using

the

Wireless

netWork

camera

systems

described

herein,

the

perimeter

can be

visually

monitored

Without

risk

to

military

personnel.

[0058]

With

the

vast

expanses

that

a

border

patrol

monitors,

it

is

impossible

to

visually

monitor

all

activity

using

border

patrol

agents.

Using

the

Wireless

netWork

camera

systems

described

herein,

remote

monitoring

of

border

regions

can

be

achieved.

A

larger

number

of

vital

regions

of

the

border

can

be

monitored

for

unauthoriZed

access

using

the

same

number

of

border

agents,

providing

cost

savings

While

improving

e?i

ciency.

By

integrating

internal

video

analytics

softWare,

dynamic

frame

and

bit

rate

control

(e.g.,

alloWing

for

sloWer

frame

and

bit

rates

When

nothing

is

happening,

but

sWitching

to

faster

frame

and

bit

rates

for

improved

video

quality

during

critical

events),

and

satellite

IP access

into

the

base

station,

border

regions

can

be

covered.

[0059]

Mining

and

Underground

Applications

[0060]

Underground

mine

safety

has

emerged

as

a

pressing

issue

WorldWide.

Various

countries

and

states

have

begun

using

communication

technologies

to

improve

mine

safety.

One

primary

objective

is

to

maintain

and

ascertain

the

health

Jun.

2012

and

Well-being

of

mining

personnel during

normal

and

emer

gency

conditions.

NeW

technologies

are

applied

to

address

voice

communications,

hoWever,

video

surveillance

and

monitoring

can

provide

additional

avenues

to

increase

safety.

Furthermore,

video

surveillance

can be

used

to

gather

infor

mation

and

improve

the

ef?ciency

and

reduce

doWn

time

for

mining

production.

HoWever,

the

inherent

nature

of

mining

is

not

conducive

to

Wired

camera

deployment.

The

Wireless

camera

system

described

herein

can

be

implemented

to

moni

tor

underground

and

mining

by

video

surveillance.

[0061]

Di?icult

Environments

[0062]

In

many

environments

(e.g.,

near

or

under

Water

or

haZardous

chemical

environments),

access

to

Wired

poWer

supplies

can

be

dif?cult

if

not

impossible.

One

example

can

be

the

environment

in

and

around

sWimming

pools.

In

such

environment,

Wireless

camera

systems

described

herein

can

be

implemented

to

monitor

pool

safety

by

video

surveillance.

Additionally,

in

a

chemical

plant

or

processing

plants

Where

caustic

or

haZardous

material

conditions

may

not alloW

poWer

cabling

to

exist

or

Where

the

installation

of

poWer

cabling

may

be

impractical,

the

Wireless

camera

system

described

herein

can

be

implemented

to

monitor

plant

safety

by

video

surveillance.

[0063]

Alarm

Veri?cation

[0064]

Due

to

the

number

of

false

alarms

created

by

secu

rity

systems,

many

police

departments

are

reluctant

to

respond

to

alarms

unless

there

has

been

“visual

veri?cation”

that

the

situation

merits

a

response.

The

Wireless

netWork

camera

systems

described

herein

can

provides

an

easy

to

install

(no

poWer

needed)

camera

system

to

alloW

for

remote

visual

alarm

veri?cation

[0065]

FIG.

1

is

a

block

diagram

of

a

battery

poWered

Wireless

camera

100

for

a

Wireless

netWork

camera

system.

One

energy-saving

feature

of

the

battery

poWered

Wireless

camera

100

is

that

the

Web

server

has

been

removed

from

the

camera 100

itself

By

not

having

the

Web

server

functionality

in

the

Wireless

camera

100,

the

camera 100

need

not

con

stantly

be

ready

to

respond

to

access

from

remote

clients,

Which

access

the

Web

server

to

initiate

data

transmission.

In

one

implementation,

the

Wireless

netWork

camera 100

can

be

poWered

for

many

months

using

an

internal

battery

102.

The

battery

102

can

include,

e.g.,

solar

cells,

galvanic

cells,

?oW

cells,

fuel

cells,

kinetic

poWer

generators,

or

other

environ

mental energy

sources.

[0066]

Battery

poWered

Wireless

netWork

camera

operation

can be

achieved,

for

example,

at

full-motion

frame

rates

in

excess

of

10

frames

per

second

at

a resolution

of

320x240

pixels.

The

Wireless

camera

100

can

be

connected

through

a

Wireless

netWork

150

With

a

base

station

160.

The

Wireless

camera 100

includes

a

high-bandWidth

radio

frequency

(RF)

transceiver

104

and

a

loW-bandWidth

RF

transceiver

106

for

communicating

With

the

base

station

160

through

the

Wireless

link

150.

The

Wireless

camera

100

also

includes

a

central

processing

unit

(CPU)

110

for

controlling

various

function

alities

associated

With

the

camera.

[0067]

In

certain

implementations,

the

CPU

110

can be

replaced

by

a

simpli?ed

micro-coded

engine

or

state

machine,

or a

hard-coded

state

machine.

For

example,

the

micro-coded

engine

or

state

machine

can

be

similar

to

that

of

an

RF

ID

tag

With

limited

response

to

input.

This

is

because

the

Wireless

camera

100

can

perform

a limited

number

of

prede?ne

functions

and

those

functions

can be

programmed

into

the

micro-coded

engine

or

hard-coded

state

machine.

In

this

manner,

the

poWer

requirement

and

the

cost

of

the

camera
