Operation
By default, the radar provides a 1280x720, two frames per second (FPS) stream using the MJPEG
codec. Higher resolution, frame rate, and quality requires more bandwidth. Use the default values
initially, and then modify and test them incrementally to determine when bandwidth and quality
requirements are met.
The video stream uses a protocol generally referred to as Real-time Transport Protocol (RTP), but
there are actually many protocols involved, including Real-Time Transport Control Protocol (RTCP)
and Real Time Streaming Protocol (RTSP). The video stream URL incorporates the IP address of
the radar. Using the radar’s default IP address, the URL is rtsp://192.168.0.250:554/map.
Accessing the radar’s video stream requires authentication. You can use the name and password for
any of the radar’s users. See

Radar Page
On the Radar page, you can define:
•
The radar’s scan rate: 2 Hz, 5 Hz, or 10 Hz
There is a correlation between scan rate, detection range, fast moving object detection, and
tracking performance. 2 Hz provides more detection range and better human detection. 10 Hz
provides less detection range, but better fast moving object detection and better tracking
performance. For example, at the 10 Hz scan rate, the radar tracks fast traveling cars more
accurately and declares those tracks more quickly.
•
Whether the radar is On or in Standby mode.
•
The radar’s range: for US model, 800 m; for EU
model, selectable.
•
The radar’s sensitivity: Low, Mid, or High. Lower
sensitivity can reduce false alarms or small-object
detection, but could miss some objects.
•
Whether you are using this radar on its own or in
conjunction with other radars. If you are using this
radar in conjunction with one or more other radars,
under Standalone, select No, and then define a
Chirp Slot for this radar. Specify a unique chirp slot
value for this radar to prevent interference from other
radar beams.
•
Alarm regions: Detection is enabled and alarms are
triggered; appear in the radar display with red
borders.
•
Exclusion regions: Detection is disabled and alarms
are not triggered; appear in the radar display with yellow borders.
•
Detection regions: Detection is enabled but alarms are not triggered; appear in the radar display
with pale green borders (the radar’s range appears as bright green).
