Alarm Functions

Advanced Video Motion Detection
The SNC-RX550 is equipped with a built-in advanced
video 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 with conventional motion
detection, the SNC-RX550 utilizes the last 15 frames
to calculate motion detection information and to
trigger the alarm when motion is detected. This
prevents unwanted noise components from
accidentally triggering an alarm, providing more
accurate detection and reducing the number of false
triggers.
Unattended Object Detection
The SNC-RX550 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.
The unattended object detection function and motion

detection function cannot be used simultaneously.
Sensor IN/Alarm OUT ports
Equipped with two sensor inputs, the SNC-RX550
can receive triggers from external sensors. Also, two
alarm outputs can be used to trigger other devices to
perform a variety of actions.
Pre-/Post-Alarm Image Storage
The SNC-RX550 is capable of storing both pre-and
post-alarm images on removable media such as ATA
memory cards and Memory Stick

Image Transfer Using FTP/SMTP

alarm event can be sent to a designated e-mail
address.
