battery

poWered

Wireless

cameras

can

include

a storage

device

con?gured

to

store

the

information

at

to

be

poWered

up

to

obtain

A

frame

rate

can

be

obtained

based

on

the

operation

duration

so

that

the

internal

can

last

substantially

for

the

operational

transmission

rate

can

be

based

on

motion

detection,

and

further

Wherein

When

motion

is

detected

in

the

captured

images,

the

image

capture

frame

rate

is

increased,

and

When

motion

is

not

detected

in

the

The

internal

battery

of

the

Wireless

camera

can

be

based

on

one

or

more

of

solar

cells,

fuel

cells,

galvanic

cells,

?oW

cells,

kinetic

poWer

generators,

and

environmental

energy

sources.

The

internal

battery

output

voltage

can

be

boosted

or

regulated

by

an

active

poWer

management

cir

cuitry.

The

internal

battery

can

be

recharged

by

of

rechargeable

battery

cells

con?gured

to

extend

the

useable

lifetime

of

the

rechargeable

array

to

be

greater

than

a

The

useable

lifetime

of

the

internal

battery

can

be

extended

by

controlling

the

current

WithdraWal

of

the

rechargeable

battery

cells

to

Within

a

predetermined

current

limit.

The

controlling

of

current

WithdraWal

from

the

internal

battery

can

be

performed

through

a

high

ef?ciency

regulation

circuit

that

includes

a

sWitching

regulator

for

draWing

a

lim

ited

current

?oW

from

the

battery

cells,

and

a

capacitor

for

temporary

storage

of

energy.

The

internal

battery

can

be

replaced

by

a

high

capacity

capacitor

and

a

charging

circuitry

associated

With

the

capacitor.

The

internal

battery

can

include

at

least

a

high

capacity

capacitor

and

a

rechargeable

battery.

[0028]

Each

of

the

one

or

more

battery

poWered

Wireless

cameras

can

include

a

compression

module

con?gured

to

operate

based

on

periods

that

are

different

from

the

burst

periods.

Each

of

the

one

or

more

battery

poWered

Wireless

cameras

can

capture

and

transmit

audio

information

and

sen

sor

information.

Each

of

the

one

or

more

battery

poWered

Wireless

cameras

can be

surface

mountable

and

can

include

a

housing

that

has

a

solar

panel

con?gured

to

recharge

the

internal

battery.

[0029]

Particular

aspects

can

be

implemented

to

realiZe

one

or

more

of

the

folloWing

potential

advantages.

An

architec

tural

change

in

the

Wireless

camera

can be

implemented

to

obtain

signi?cant

poWer

savings

in

Wireless

netWork

camera

systems.

Such

a

design

change

can

offer

substantial

poWer

savings

over

commonly

understood

poWer-reducing

tech

niques

such

as

using

more

e?icient

electronic

components

in

the radio

transceivers,

image

capture,

and

compression

inte

grated

circuits.

[0030]

An

ultra-loW

poWer

Wireless

camera

canbe

obtained

Without

compromising

the

ability

of

neW

and

existing

client

system

to

access

data

using

standard

IP

connections

and

standard

or

de-facto

application

programming

interfaces

(APls).

In

particular,

the

base

station

code

can

comply

With

Well

established

IP

camera

APl’s.

Additionally,

even

though

the

Wireless

camera

can

operate

at

an

ultra-loW

average

poWer,

during

the

burst

period

When

the

camera

is

transmit

ting

data

to

the

base

station,

the

camera

can

alloW

for

poWer

consumption

in

excess

of

100

mW.

This

is

in

contrast

to

existing

Wireless

sensors

Which

Will

typically

consume

less

than

100

mW

of

poWer

When

transmitting

data.

[0031]

Multiple

Wireless

cameras

(e.g.,

up

to

16

Wireless

cameras)

can

be

assigned

to

a

single

base

station.

The

base

station

and

Wireless

camera

combination

can

deliver

all

the

intelligence

and

features

expected

for

a

commercial

grade

IP

camera

solution.

The

solution

integrates

into

existing

IP

net

Works

and

exposes

standard

video

monitoring

application

interfaces

so

that

popular

video

surveillance

data

applications

can

be

used.

This

makes

for

rapid,

seamless

and

pain

free

deployment.

From

the

netWork

perspective,

the

combo

pro

cessing

ensures

that

all

Wireless

cameras

appear

to

be

100%

compatible

IP cameras.

Video

can

be

delivered

compressed

to

industry

standard

format

such

as

M] PEG

or

MPEG-4,

ready

to

be

accessed

and

managed

by

industry

standard

softWare.

[0032]

The

base

station

can

connect

to

a

regular

Wired

Ethernet

LAN

and

on

to

the

Internet,

just

like

any

IP

surveil

lance

system.

A

seamless

integration

can

occur

over

a

stan

dard

802.1lb/g/n

Wireless

Ethernet

netWork.

Since

it

can be

Wireless

to

the

lntemet

access

point,

the

distance

range

of

the

Wireless

netWork

camera

system can

be

as

Wide

as

today’s

Wireless

systems.

The

user

can

perform

a

Walk-through

WiZ

ard

once,

and

begin

installing

multiple

security

cameras

any

Where

Within

the

range

of

the

base

station.
