SOLO – LDR ReceiverThe LDR (Low Data Rate) system is a digital videotransmission system from Cobham Surveillance.Designed to operate over very long ranges,it features domo technology at its core.The LDR receiver picks up the informational qualityvideo sent by the LDR transmitter at reducedframe rates. The high level of compression andreduced data rate means that the images can besent over great distances.Narrowband digital transmissions - occupyingas little as 50KHz of bandwidth and thereforemore easily used at UHF frequencies - aresent over the system. The LDR receiveris available in a variety of frequencybands from 300MHz to 1GHz - otherfrequencies are available on request.Security is ensured with optional AES128/256 bitencryption.Housed in a robust, water-sealed enclosure and consuming only 3W,the LDR receiver is ideal for long term outdoor deployments.The LDR system will transmit images in a non line of sightenvironment up to 2km, and line of sight to 20km dependingon mode and frequency, further range can be achieved with theoptional clip-on booster PA.Specification:OutputComposite VideoInputRF InputRS232 ControlPowerRFFrequency BandsReceive SensitivityTuning StepsModulationBandwidthsTypeAmphenolTNCAmphenolAmphenol902 to 905MHz,868 to 870MHz,457 to 458MHz (others on request)-112 to -118 dBm12KHz50, 75, 100 or 125KHz selectableCOFDMVideoLine StandardPAL/NTSCResolution SIF (352 * 288) QSIF (176 * 144)Coding ModeMPEG4Delay1 to 1.5 second end-to-endFrame Rate12, 5 or 2 frames/sDecryption FormatAES128/256 selectable (optional)ControlRemote ControlLocal ControlPhysicalDimensionSealingRS232 Control from PC GUI ApplicationFront Panel 8 channel select, RF On/Off,Range mode, Lock, AlarmL 150mm, W 120mm, H 35mmIP67PowerD.C Input10 to 16V Reverse Polarity ProtectedPower Consumption 3.5WEnvironmentTemperature RangeProduct Code:LDRRX-090090LDRRX-086087LDRRX-045045AES256RXAES128RX-20 to +60 deg C38For further information please contact +44 (0)1489 566 750
