RDR Data Recorder FAQs

RDR Data Recorder captures radar video, primary and secondary radar tracks, AIS, ADS-B, navigation data, camera video, audio, screen video and arbitrary network packets. Data from all channels is synchronised in a common recording file, so all channels stay synchronised on replay.

• Radar video: ASTERIX CAT-240; turnkey systems with radar input cards can record analogue radar signals
• Plots and tracks: ASTERIX CAT-48
• ADS-B: ASTERIX CAT-21
• AIS and navigation data: NMEA-0183, including over TCP
• Camera video: RTSP network video and DirectShow devices
• Audio: RTP and DirectShow audio
• Screen video: via a lightweight 'Agent' client
• Generic network packets, recorded without interpretation

Recordings can be made to a local hard drive or NAS. See RDR Data Recorder.

RDR Data Recorder has no intrinsic limit on recording length; it is limited by available disk space. For continuous recording, RDR Data Recorder supports rolling recording, where data older than, for example, 30 days is deleted automatically.

The built-in recording scheduler starts sessions at specified dates and times, can repeat them, and deletes sessions older than a specified age, so RDR Data Recorder can keep a continuous record of a set number of previous days. Sessions can also be deleted automatically based on disk usage percentage.

Yes, provided your sensor or system outputs its data on a network. RDR Data Recorder can record generic network packets on an open channel without interpreting them, and replays them like any other channel, synchronised with the radar data.

If your sensor outputs on an RS-232, RS-422 or RS-485 serial channel and your computer has a suitable interface, Cambridge Pixel can also provide a serial-to-network utility so the data can be recorded (see the tools and utilities FAQs).

Use SPx Open Access, which reads and decodes the radar video in Cambridge Pixel Recording (CPR) files made by RDR Data Recorder. Your own C++, .NET or MATLAB code can then analyse the video on Windows or Linux, for a selected time range and channel of the recording.

RDR Data Recorder's replay also outputs each data source in the original recording as a synchronised network stream, so recordings can be fed to other applications.

RDR Data Recorder writes track messages to an SQL database while recording. You can filter the results with SQL queries and export them to a .csv file for analysis in Microsoft Excel or other packages.

Navigation, AIS and ADS-B data are also recorded to the SQL database. The SQL feature and its use are described, with examples, in Section 22 of the RDR Data Recorder user manual.

Both. RDR Data Recorder is available as software for Windows, or as a turnkey PC system supplied with the appropriate radar input/output cards. For system integrators and OEM developers, the software and radar input/output cards are also available as components for a custom system.

For radars with analogue signal outputs, or display equipment that expects analogue radar signals, turnkey systems can be supplied with up to three radar input/output cards installed. For analogue replay, RDR Data Recorder works with the HPx-310 radar output card.

Contact Cambridge Pixel for standard system options, or see RDR Data Recorder.

RDR Data Recorder replays a recording through user-defined output channels, routing each channel's data to a suitable physical output with all channels kept synchronised. For example, AIS data can be replayed on the host's serial port or Ethernet port, whichever one it was recorded from.

• Radar video is replayed as ASTERIX CAT-240, or as analogue radar signals through an HPx-310 card.
• You can jump to specific times or events, and loop replay between start/stop markers set on the timeline.
• Recordings, or sections of recordings, can be exported.

Yes. RDR Data Recorder has a socket-based control interface, so recording and replay can be managed remotely over the network as well as from the local user interface.

Recording sessions can also be started automatically by the built-in scheduler. Events are logged automatically (for example loss of channel data), by the user at the click of a button, or against a location on the overview display.
