HDTV and megapixel network cameras in action

High security premises

Casinos and airports, together with passport controls,

banks and similar high security premises, are areas

where the requirements on the surveillance cameras

often include high image quality and detail as well as

full frame rate, making HDTV network cameras the

natural choice.

Transportation

Security and safety for both passengers and sta are

highly prioritized issues for public transportation author-

ities around the world. HDTV and megapixel cameras at

stations, terminals and airports as well as onboard buses

and trains, provide valid evidence in the event of criminal

incidents, vandalism and insurance claims.

Retail

In retail, theft and shrinkage can be drastically reduced

through eective video surveillance. HDTV and mega-

pixel network cameras have an important role to play,

for example by giving an overview – without any blind

spots – of stores.

City surveillance

HDTV and megapixel network cameras are typically

used in city surveillance situations to provide high-

resolution video streams from locations where there is

a need to clearly identify people and objects, or get a

larger overview, either while viewing live or recorded

video. Full frame rate, which is a requirement in HDTV

standards, makes it easier to monitor intense and fast

moving trac.

Dierent industry segments put dierent requirements on video surveillance solutions, but one shared challenge is

getting enough image quality to ensure reliable identication of people and objects. HDTV and megapixel network

cameras are used in a number of key industry segments to solve this challenge, including:

Pixels per meter -

a best practice

In the surveillance industry, the best practice for an

overview image is to ensure that a scene has 70 to

100 pixels per meter (20-30 per foot), whereas with

face identification, as much as 500 pixels per meter

(150 per foot) may be required. This means, for ex-

ample, that if you want to be able to accurately

identify people passing through an area that is two

meters wide and two meters high, the camera needs

to provide a resolution of more than 1 megapixel

(1280x1024 pixels).

The Society of Motion Picture and Television Engineers,

SMPTE, has defined the two most important standards:

SMPTE 296M and SMPTE 274M. In short, SMPTE 296M

defines a resolution of 1280x720 pixels using progres-

sive scanning, while SMPTE 274M defines a resolution

of 1920x1080 pixels using either interlaced or progres-

sive scanning. Axis HDTV network cameras comply

with key parts of the SMPTE HDTV standard, which is a

unique property of Axis’ products. A network camera

that follows the HDTV standards is guaranteed to pro-

vide high resolution, 16x9 aspect ratio, full frame rate

and extended color fidelity, thereby ensuring an overall

superb image quality.
