1 May 2008 Zilog and EE-SGI Present epir TM The Next Generation of PIR Motion Detector Technology (Over View) 1

2 The epir TM Statement epir TM is a revolutionary technology used for passive infrared (PIR) based motion detection. epir TM is a technology that has significantly better reliability & performance than (high end current) Digital PIR detectors. Provides a dramatic improvement in both sensitivity and stability (false alarm & pet immunity). Meets or exceeds all applicable standards (present and proposed). Enables additional features without additional cost. White Light Immunity Auto LED Real time Diagnostics (self test) and more 2

3 Traditional PIR Detectors Traditional PIR s are a commodity sold largely on price Differentiation from competitors is difficult Designs are mature in nature Little room for improvements Inherent limitations remain High component count (low MTBF) Bulky electrolytic capacitors required Time consuming to assemble and test Band-Aids applied to overcome design pitfalls 3

4 What makes epir TM possible? New MCU product families with advanced capabilities have allowed a revised look at the overall PIR detector design Unique software techniques have been developed that overcome previous limitations This fresh look has produced a revolutionary step in PIR detector technology called the epir TM with Sigma-Delta Technology 4

5 The epir TM Technology Advanced new Zilog Z8 XP MCU allows the hardware to be greatly simplified Supports powerful new software techniques developed by EE-SGI 5

8 PCB Comparison Bottom Side Top Side Traditional epir TM Traditional epir TM Fewer components means simpler layout and no electrolytic capacitors 8

9 epir TM Sensitivity Based on statistical information, not signal amplitude Typically exceeds comparative benchmarks Creep detection well bellow 0.1 MPS Speed detection exceeds 5 MPS Excellent delta temperature performance Performs better near 35C ambient temperature (R.B.T.) Sensitivity controllable in epir TM software Supports user selectable sensitivity for the application Not required to counter false alarm problems 9

10 epir TM Stability Extremely stable Exceeds comparative benchmarks Tested under worst case conditions Maximum sensitivity Minimal pulse count setting Minimal pet immunity setting Cycling temperatures Variable sunlight and other factors Field data confirms internal test results Dramatic improvement in false alarm immunity Increased stability AND lower system cost! 10

12 epir TM Pet Immunity Pet immunity tested to over 48 Kg Production product can be rated to 40Kg Consistently exceeds comparative benchmarks Minimum pet immunity (15 to 20 Kg) inherent without any degradation of catch performance Alternate lens or masking not required epir TM utilizes sharp frequency discrimination and waveform shape analysis 12

13 epir TM White Light Immunity Exceeds 10,000 Lux White Light Immunity Pulsed Swept Continuous Target motion still detected under strong white light Can not be blinded KEY requirement for outdoor motion detection! No filtering or additional components required Advanced software analysis with inputs from Ambient light level obtained from LED in reverse mode Pyroelectric sensor DC offset and signal 13

14 epir TM AUTOLED Feature The unique method of enabling Walk Test LED jumper now ON and AUTO (instead of OFF) LED = ON works the same way (LED always active) LED = AUTO controls the LED automatically LED is normally off until action taken LED (for walk test) is enabled by shining light on detector Eliminates removal of the detector cover for walk testing Guarantees LED will be disabled for normal operation AUTOLED function can be customized as required 14

15 epir TM Approvals EMC EN EN CFR, FCC part 15:06 Sub B CISPR 22 ICES-003 Product Safety EN (CE mark) epir expected to meet or exceed 6 GHz requirement for EMC radiated immunity without additional hardware or cost Current requirement = 2 GHz (effective Sep 2007) Future requirement = 6 GHz (required in 2 to 4 years) 15

16 The epir TM Advantage Significantly improved performance & reliability Can drop into existing plastics & optics Superior sensitivity and range Extreme false alarm immunity Eliminates electrolytic capacitors Exceptional pet immunity Tested to 48Kg Integral white light immunity (without cost) Exceeds 10,000 Lux White Light Immunity Pulsed / Swept / Continuous Detector remains non-blinded AUTO LED feature (without cost) Full environmental compensation Meets the current 2GHz EMC standard Projected to meet future 6GHz standards as well Outperforms digital solutions at an analog price! 16
