FULL OVERVIEW
Conventional PTZ cameras allow the user to pan, tilt and zoom,
but not to see the whole video scene – just one portion at a
time. The AXIS 212 PTZ gives the user the whole picture, then
allows instant pan/tilt/zoom to get the details.
The dotted lines show the limited area covered by conventional PTZ cameras.
If the man on the left was shoplifting, he would be out of view.
The AXIS 212 PTZ lets you view the entire monitored area. There are no
hidden areas.
INSTANT PAN/TILT/ZOOM
The 3x zoom provides instant, one-click optical zoom func-
tionality. Consequently, from the overview image, a security
officer can zoom in 3 times on any suspicious behavior by
just clicking on the part of the image where it's happening.
No other PTZ camera can zoom in instantly on off-centered
action. And since there is no movement in the lens system, the
camera instantly changes the field of view.
It's this simple:
> Overview of the whole scene in perfect image quality
> Pan, tilt and zoom with one click
> Follow a visitor with one click
> Return to overview with one click
Whether in overview or fully zoomed in, you get up to 30 frames per second in
VGA resolution. Zooming – the instant, one-click, 3x zoom – does not decrease
the image quality. Edges do not become jagged. More importantly, when you
zoom in on suspicious behavior, you increase your chances of being able to
identify what is happening and who is involved.
NO MOVING PARTS
The AXIS 212 PTZ achieves full overview as well as instant
pan/tilt/zoom without any moving parts, which means no
wear and tear. This unique feature is based on two determining
factors:
The advantages of no moving parts are considerable:
RESOLUTION –
SHARP AND MAINTAINED
Many cameras cannot deliver an overview with sharp
resolution, nor maintain resolution when zooming. The
AXIS 212 PTZ can, because it has such outstanding image
resolution to start with.
OVERVIEW – THE STARTING POINT
By having a full overview of 140° (pan), the AXIS 212 PTZ
wastes no pixels. This means that the full image sensor
can be used for image quality purposes – and the difference
is astonishing.
180/360° degree cameras cover a bigger area, but at the expense of spreading
the amount of available pixels (resolution) over areas that are often of no
3x zoom
interest. With the AXIS 212 PTZ, you see everything you need to see, and the
image is sharper.
SUPERIOR IMAGE QUALITY
The AXIS 212 PTZ offers progressive scan and advanced signal
processing based on a 3 megapixel CMOS sensor.
> A wide-angle lens combined with a 3 megapixel sensor
> Utilization of the full "windowing" possibilities:
the camera captures predetermined sections of the
overview without mechanical motion.
> No wear and tear – and a level of durability and
reliability far ahead of conventional PTZ.
> No noise – thus making the camera even more discreet.
> No way to tell where the camera is looking. In fact,
the camera seems to follow anyone on the premises.
> No delay for mechanical movement – enabling instant
pan/tilt/zoom, and thus no time lag in the images.
