| SMART combines three detection technologies; Microwave, Passive Infrared and Active Infrared in a single small product. SMART will trigger an alarm only after it verified the intrusion by means of both technologies- Microwave, and Passive Infrared. As a result, a problem of "false alarms" is eliminated absolutely. By using this technique, a high sensitivity level may be adjusted in both detection technologies without the need of pulse count. SMART will impose "OR" mode in distress. If, from any reason, the PIR detection channel is neutralized (for example, the detector's front was masked), the Microwave detection channel will guard the protected area- even if the detector has been adjusted to work in "AND" mode. While SMART provides highly reliable movement detection, it ensures excellent protection against any attempt to disable its operation by blocking (masking) its near field-of-view, whether the alarm system is Armed or Disarmed. SMART will detect any type of masking material, including transparent - that is even if the lens was sprayed with paint or covered by a sticker. The protection against masking achieved by a continuous scan of active infrared beams. |
