End to interlace problems

>
Interlaced scan

>
Each image formed from two interlace fields

>
Blurriness from capturing moving objects,


even when connected to a DVR

>
Benefits



Superior image quality


Full image details


Precise, accurate information

Crystal clear

images even

with a high

degree of motion

in the scene

Power over Ethernet

Both network cameras with and

without built
-
in support for PoE

can take advantage of a UPS device

Megapixel resolution

>
Stuck with NTSC/PAL resolution

>
0.4 Megapixel at 4CIF and 0.1 at CIF

>
Limited image details

Many resolutions

Different aspect ratios

1 megapixel is 10x the

resolution of CIF,

2 megapixel is 20x!

Digital PTZ

>

Benefits


More details, easy identification


Digital PTZ, higher reliability and


simultaneous pan/tilt

Integrated PTZ input/output control

>
Cabling separate from the video signal

>
Costly and cumbersome

>

Benefits


Less cabling, cost savings, increased functionality

and integration potential

Integrated I/O

can trigger

anything and be

triggered by anything

PTZ commands

sent over the

IP network

PTZ control over

the same network

that transports

the video

Integrated PTZ input/output control

Example: Typical I/O use


integration with alarm

6



Integrated
audio

Audio captured at

the camera

Synchronized with

the video

Can be integrated into

the same video stream

Two
-
way audio (duplex,


half duplex, simplex)

>

Benefits


Many possibilities: simplex, half duplex, full duplex


Synchronized audio and video


Easy to install, cost savings

>
Only possible with separate audio lines to
the DVR

Integrated
audio

>
Entrance control



Remote dialog and gate/door control

>
Listen in on remote sounds


Audio surveillance

>
Provide audio feedback

to surveillance scenes


Example: Communicate and

open a door remotely

Secure communication

>
No encryption

>
No authentication

>
Anyone can tap into the video or replace the


signal from a camera with another video signal

Video encryption

Authentication using

encrypted certificates

Authorization: to verify

and approve the identity

of the device

Privacy

>

Benefits


Secure image capture


Secure transmission


Evidence trail secured

Examples of achieving privacy


VPN


SSL/TLS (HTTPS)

Flexible, cost
-
effective
infrastructure choices

www.axis.com

>

Benefits


Image quality, flexibility, scalability, future
-
proof


Resulting costs comparatively low

>
Expensive coax, proprietary fiber, wireless

>
Distance affects image quality

>
Adding power, I/O and audio further complicates


this situation

Flexible, cost
-
effective infrastructure choices

IP = established,

standardized,

interoperable

Digital images =

no quality reduction

Many streams

transmitted

over the same line

A single network wire =

hundreds of simultaneous

full frame rate video streams

True digital solution

>
With every conversion image quality is lost:


Analog signal digitized in camera’s DSP


Digital signal converted back to analog for
transport over coax


Signal once again digitized at the DVR for
recording

>

Benefits


Superior image quality

Images digitalized once

Stay digital

No unnecessary

conversions

No image degradation

The cost per channel

>
Flexibility and performance


CONSIDER

>
Back end applications and storage

>
Industry standard, open
-
system based
servers vs. proprietary hardware like a DVR

>
Infrastructure used


Can it be leveraged for other applications?
