The IntelliSense DUAL TEC DT-400T series motion sensors have been paid the highest compliment possible by being the most copied motion sensor in the world. Based on microwave/PIR technology, the DT-400T series' patented microwave activation circuit provides superior catch performance and virtually eliminates false alarms. For years many manufacturers did not believe that dual technology is the wave of the future. Today, almost all major manufacturers of motion sensors in the security industry have introduced products to directly compete with the industry standard DT-400T series. The DT-400T series motion sensors provide cost-effective, proven performance, and are found in applications from homes to palaces around the world.

• Microwave/PIR Technology
  The use of dual technology provides excellent detection while virtually eliminating false alarms and costly service calls.
• Patented Microwave Activation Circuit
  This exclusive patented feature helps eliminate false alarms by ensuring every infrared-generated signal is confirmed by a solid moving target.
• Microwave Supervision
  Independent circuit supervises microwave against failure.
• Microwave Range Adjustment
  Detection pattern can be easily adjusted to suit each individual application.
• Automatic Temperature Compensation
  No loss of sensitivity as room temperature nears body temperature.
• Patented "Look-Down" Zones
  Superior detection capabilities are provided by detection patterns that begin directly beneath the sensor and extend to its maximum range.
