Dual Encoding Capability
The SNC-RZ50P is equipped with a dual encoding
capability that enables the camera to generate both
MPEG-4 and JPEG images simultaneously. For example,
you can set up your system to transfer MPEG-4 images
over a WAN or an Internet VPN, where network
bandwidth is limited, while storing high-resolution JPEG
images on a server configured on the LAN.

Image Stabiliser

The image stabiliser function minimises the appearance
of shaky images caused by low-frequency vibration so
that stable and sharp images are provided. This function
is useful for outdoor surveillance and traffic monitoring
applications.

Day/Night Function

The SNC-RZ50P offers a Day/Night function to provide
optimised sensitivity in both day and night environments.
As the scene darkens, the infrared cut filter is automati-
cally replaced with a clear filter and the camera switches
to B/W mode, requiring a minimum illumination of less
than 0.3 lx. In this mode, the camera is also sensitive to
near IR illuminators, allowing it to operate even in 0 lx*
conditions.
*2 0 lx means absence of visible light to the naked eye.

Alarm Functions

Intelligent Motion Detection
The SNC-RZ50P is equipped with a built-in Intelligent
Motion Detection function that can trigger a variety of
actions such as storing and transferring images or that
can trigger an external device through its output relays.
Unlike conventional motion detection schemes where the
current image is compared to the previous frame, the
SNC-RZ50P utilises the last 15 frames to perform motion
analysis and to trigger the alarm. This prevents unwanted
noise components from accidentally triggering an alarm,
providing a more robust detection method, thus reducing
the number of false alarms.
Intelligent Object Detection*
The SNC-RZ50P can detect objects that have been left in
one place for a specified duration. Up to four detection
areas can be designated. This feature can be useful for
applications such as detecting suspicious objects left in
public spaces, or for detecting stalled cars or accidents
on the road.
*3 The Intelligent Object Detection function and Intelligent Motion
Detection function cannot be used simultaneously.
Sensor in/Alarm out
Equipped with two sensor inputs, the SNC-RZ50P can
receive triggers from external sensors. Two alarm outputs
can also be used to trigger other devices to perform a
variety of actions.
Pre-/Post-Alarm Image Storage
The SNC-RZ50P is capable of storing both pre-and
post-alarm images on removable media when an alarm is
triggered.
Image Transfer Using FTP/SMTP*
All of the pre-/post-alarm images stored at the time of an
alarm event can be transferred to an FTP server for later
viewing. Also, a still image at the time of an alarm event
can be sent to a designated e-mail address.
*4 All images transferred using SMTP are in JPEG format.
Anti-tampering Function*
Incorporating a digital signature technology using Public Key
Infrastructure (PKI), the SNC-RZ50P allows users to verify the
origin of images and ensure the integrity of images against
tampering. This is done by creating a digital certificate for
each camera manufactured and applying digital signatures in
the form of metadata to all images produced by that camera;
this combination assures that an image produced by a
camera is unique to that camera.
*5 This function is available with a software upgrade. For more details
please contact your nearest Sony dealer.
