  2. System Features • Microprocessor Controlled • Uses Windows XP • Touch Screen LCD Display • Multi-channel Analyzer • Broadband Internet Card • High Resolution Digital Camera • 2” x 2” NaI Detector(s) • NEMA enclosure • Strobe & Audio Alarm

  3. User Flexibility • Detector(s), up to 250 feet from monitor • Accommodates up to 9 detectors & cameras • Alarm threshold can be user defined • Alarm details stored on monitor’s hard drive • Optional notice to remote(s) • Photo of event – 1-9 images • Isotope ID plus MCA spectrum • Optional supervisor intervention to reset • Monitor to include or exclude medical isotopes

  4. Monitor Mode Screen • Display counts above average background • Or can be in “Sleeping Watchdog” Mode

  5. Alarm Screenin auto-reset mode

  6. Alarm Screenin manual reset mode

  7. Upon Alarm Activation • Strobe & Audio alarms activate • Counts exceeding background noted on the screen, in red • Date & time is recorded • Picture(s) is taken of the event • Isotope spectrum is analyzed • Isotope ID is made • Detector location is noted • All data & pictures are stored on the HD • Optional Alarm alert(s) are forwarded
