Easy Installation
Supports Four IP and Four MAC Addresses* 2
The four-channel models, including the blade encoders,
support four IP and four MAC addresses. This enables you to
monitor your video cameras via the SNT-EX/EP Series using
each camera’s unique IP address. Furthermore, defining an IP
address for each camera is very simple, so system setup can
be achieved quickly.
Remember Function* 3
MAC address information is stored on the 1U and 3U rack
stations. After installing the blade and assigning the IP
address, the IP address is then stored in the rack station.
In the event of a failure on a blade encoder, you can simply
replace the card with a new one and be up and running very
quickly.
ONVIF Conformance
(Open Network Video Interface Forum)
In line with Sony’s commitment to open standards, the
SNT-EX/EP Series conforms to ONVIF™ software specifications.
ONVIF defines a common protocol for the exchange of
information between different network video devices
regardless of manufacturer, and realizes greater
interoperability in multi-vendor network video systems.
Support for IPv6
The SNT-EX/EP Series supports Internet Protocol Version 6 (IPv6).
Versatile Interfaces
Third-party PTZ Control via Serial Interface RS-422* 4 /485* 5
The SNT-EX Series has an RS-422/485 serial interface. It also
has built-in protocols to support the control of third-party
analog Pan/Tilt/Zoom (PTZ) cameras, plus support of some
setting adjustments. For further ease of installation, the
camera ID of the PTZ camera can be set on the SNT-EX Series,
so there is no need to manually change or set the camera
address.
Coaxitron Protocol Support* 1
The SNT-EX Series supports the Coaxitron Protocol, which
allows both video and command signals to be transmitted
with just a single BNC cable. This means the SNT-EX Series
can support a wider variety of monitoring environments.
Local Storage * 6
Stream Support* 7
Video can be stored on optional USB memory and then
streamed by using RTP/RTCP/RTSP protocol.
USB Port for External Data Storage
Data storage capacity is available with USB flash memory,
onto which all the compressed video formats − MPEG-4, JPEG,
and H.264 − can be recorded. Periodic recording is possible
and pre-/post-alarm images can also be recorded.

• Tamper Alarm
When an attempt is made to tamper with the camera, such
as spray-painting the lens, the SNT-EX Series detects this and
triggers an alarm. This event can be used to activate the
camera relays, or even to start the Voice Alert function.
• Advanced Audio Detection* 7
Unlike conventional audio detection where an alarm is
triggered based on a simple preset audio level, the SNT-EX
Series takes into account the ambient sound levels as well as
its associated frequencies to establish a threshold where any
audio level above this is treated as an alarm.
Audio Functions* 1 (SNT-EX Series)
Voice Alert
The SNT-EX Series can store up to three pre-recorded audio
files. Upon initiation, either manually or via an alarm, these
video encoders can play out one of the three pre-recorded
audio files via a locally connected active speaker.
Ambient Sound Filter
The SNT-EX Series is capable of learning ambient sound and
suppressing extraneous noise.
Dynamic Range Compressor* 7
To prevent audio clipping from occurring due to high audio
levels, these video encoders employ the dynamic range
compressor, which dynamically controls the gain to maintain
incoming audio at a proper level.
Echo Cancellation
The SNT-EX Series has an echo-cancellation capability. This
feature cancels the echo that would otherwise occur
between the operator site and the video encoder site, when
speakers and microphones are used in the system.
