Instant pan/tilt/zoom
The 3x zoom provides instant, one-click optical zoom functionality. 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
Instant pan/tilt/zoom View large (400kB)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 the use of a unique 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.
The advantages of no moving parts are considerable:
- 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.
- Resolution - Sharp and maintained accross the entire image
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 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.
Oversampling
Oversampling is a technology that uses the advantages of a high-resolution sensor
(2048x1536 pixels) in its full format. This means that, whether in full overview
mode or when zooming in, full 1:1 VGA resolution of 640x480 pixels is maintained
- resulting in a brighter image, more detail and higher contrast. When you zoom
in 3 times, you obtain normal VGA 1:1 resolution
Bandwidth saver
The AXIS 212 PTZ is able to efficiently "window" a specific portion
of the 3 megapixel sensor grid. In doing so, the camera filters out unnecessary
information that offloads your network and storage capacity, and lets you capture
a well-defined "image concentrate".
Resolution Bandwidth Storage
VGA 2.4 Mbit/s 4 GB/day
3 Megapixel 24 Mbit/s 40 GB/day
Example based on Motion JPEG compression. File size of 30 vs 300 kB. Frame rate
for viewing 10 fps, storage 6 fps. Motion detection set at 25%.
