During nighttime monitoring applications, camera
sensitivity is one of the most important factors in
capturing a clear image.
Sony cameras that incorporate SuperExwave technology
achieve extremely high sensitivity levels especially in the
near infrared wavelength region of the electromagnetic
spectrum. As a result, sensitivity levels in the visible
wavelength region are increased by approximately 10 %,
while the sensitivity in the near infrared region is increased
by approximately 50 % when compared to Exwave HAD
technology. Sony SuperExwave cameras employ advanced
photo-diode sensors capable of capturing a great amount
of light in the near infrared region while efficiently
converting this light to electric signals thus achieving highsensitivity levels.

DynaView™ Technology
(SSC-DC590 series/SSC-DC570 series)
Newly developed DynaView technology achieves an
incredible dynamic range that is 128 times wider than
conventional cameras. Users can capture clear images
even in extreme high-contrast lighting environments. By
activating the DynaView mode, the camera will capture
the same image twice - first with a normal shutter speed,
and then with a high shutter speed. The newly developed
LSI technology then combines the dark areas captured at
normal shutter speed with the bright areas captured at
high shutter speed to create one image.
The result is an extremely high-contrast picture that is
unattainable with a conventional camera. (See Fig. 3)
Additionally, DynaView technology allows the cameras to
achieve more powerful Back- Light Compensation (BLC).
While conventional BLC can result in over exposure when
capturing background images, DynaView reduces this to a
minimum by using a high shutter speed for the
background, which consequently provides optimum
exposure for both the subject and the background.

*This chart has been simplified to show the difference in sensitivity between
SuperExwave and Exwave HAD. The values are for reference only.
Fig.2 SuperExwave vs Exwave HAD Spectral Sensitivity Comparison
Users can choose from four preset gamma curves,
including two unique gamma curves, so that the brightness
levels of captured images are controlled precisely. Images
in their entirety can be displayed clearly and accurately.
(i.e. not too bright and not too dark). (See Fig. 4)
One of the two unique gamma curves reduces the
brightness level of the dark portions of the image, while
increasing the brightness level of the bright portions of the
image, which is ideal for scenes that have very little
contrast (SCENE2; See Fig. 5).
The other unique gamma curve increases the brightness
level of the dark portions of the image, while reducing the
brightness level of the bright portions of the image
(SCENE3; See Fig. 5).
By selecting a gamma curve that is appropriate for a given
scene, captured images can be reproduced clearly and
sharply.

JPEG vs. MPEG-4
JPEG compression, which is conventionally used in
surveillance and monitoring systems is very good for
capturing high-quality still images. MPEG-4, on the other
hand, is ideal for image transfer over a network while
maintaining high-quality moving images. This is because
MPEG-4 requires a relatively small amount of network
bandwidth as a result of its structure as can be seen
below.

Activity Detection vs. Motion Detection
(SNC Series Cameras)
The following is a brief explanation outlining the
differences between Motion Detection and Activity
Detection: The general difference in concept between the
two detection methods is that Motion Detection utilizes
vector information associated with movement while
Activity Detection utilizes the difference in illumination
between frames. Activity Detection is available with JPEG
compression while Motion Detection is available with
MPEG-4 compression.
Activity Detection
Sony Activity Detection systems utilize hardware that
performs difference calculations in luminance between
frames. The absolute value of the difference in luminace
of each pixel is taken from one frame to the next. If the
sum of the difference is greater than a preset threshold,
then an alarm is triggered.
Note: Each frame in MPEG-4 is referred to as a Video Object Plane (VOP).
A Group of VOPs (GOV) comprises of one second* of video. An I-VOP is the
first (Initial) “frame” of a GOV and is often referred to as an “anchor.” The
I-VOP is similar to a JPEG image. P-VOPs are “Predictive” VOPs and only
“captures” movement relative to the previous VOP.
*The default GOV setting for Sony MPEG-4 cameras is one second.
The length of a GOV can be set between one and five seconds.
Rough Calculation of Data Size
JPEG
With JPEG at 30 fps, 1 sec = 30 images. Assuming each
JPEG image is 30 KB in size, then one second of video is
900 KB. At 8 bits per Byte, this translates to 7.2 Mb/s
MPEG-4
With MPEG-4, the I-VOP is approximately 30 KB in size.
Assuming there is little movement in the image, each
P-VOP is approximately 2 KB in size. This means that 1
second of data is approximately 88 KB. Again, using the
same calculations as above, this translates to
704 Kb/s. This is approximately 1/10th the size of
JPEG data.
4
Motion Detection
Motion Detection systems utilize a Sony advanced
algorithm to determine whether or not there is actual
movement in the camera viewing area. This algorithm is
based on vector information available and inherent in
MPEG-4 compression. The vector information is
determined based on the amount of movement in 16 x 16
pixel-areas in the grid.
Motion Detection has an advantage over Activity
Detection because it can reduce the number of false
alarms caused by noise. Other advantages of Sony
systems that use Motion Detection are that up to four
distinct Motion Detection areas can be assigned, and real
time indicators are available to monitor sensitivity and
threshold levels.

Adaptive Rate Control (ARC)
ARC is a feature that adjusts the compression bit rate and
the frame rate of MPEG-4 data in order to meet changing
traffic conditions over a network. Round Trip Time (RTT)
and actual IP packet loss are both monitored to determine
traffic conditions, and the bit rate and frame rate are
adjusted automatically. “Drop Outs” (a breakup in
transmitted images) can be avoided when a system is
equipped with the ARC feature. The following is a
graphical representation of how ARC works:
Without an ARC feature, as the available network
bandwidth is reduced due to high-traffic conditions, "Drop
Outs" occur.
With ARC, as the available network bandwidth is reduced
due to high-traffic conditions, the MPEG-4 data bit rate is
reduced. This lowers image resolution slightly, but smooth
moving images are still transferred.
If network traffic conditions continue to increase, then the
ARC feature lowers the frame rate of the data so that
dropouts do not occur and a continuous image stream is
transferred. This method still provides smooth moving
images at a lower frame rate.
