  1. VICON A&E SUMMIT ‘09 A Short Discussion on High Resolution Cameras

  2. Understand new terms and technology • Discuss megapixel camera benefits • Discuss megapixel camera trade-offs • Overview of new Vicon products • Look at possible product applications Goals

  3. Pixel PICture ELement Pixel count, expressed as megapixels Pixels Per Foot Progressive scan Mega Terms

  4. Megapixel Cameras • Four Major Benefits • Higher definition = greater detail • More coverage with fewer cameras • Different aspect ratio = higher efficiency • Progressive scan = stable picture

  5. Live Viewing After the Fact Multi Views Higher Definition = Greater Detail

  6. Fewer Cameras with Greater Detail

  7. Fewer Cameras with More Detail

  8. 1289 X 1024 VGA 1.3 MP Resolution Relationship 720 X 480 VGA

  9. Record the picture that is needed Different Aspect Ratio = Higher Efficiency

  10. Interlaced Scan vs. Progressive Scan • Interlaced Scan

  11. Megapixel Trade-Offs • Greater bandwidth and storage requirements • Four or more times greater • But … a 3 MP camera can replace up to 3 standard cameras

  12. Megapixel Trade-Offs • Smaller pixels are normally less light sensitive • PixelsPicture Element

  13. Lens Quality • Optics true to the edges • Chip/ Lens Alignment • Back focus New Camera; New Lens

  14. Most sellers of mega pixel cameras are selling “pixels” not image quality* Standard Lenses are made for 489 TV Lines Lens quality needs to equal camera quality Facts about lenses Les Simmonds Security Electronics Magazine

  15. Pixels Per Foot: It’s all about the details • Two ways to get detail. • Get the camera closer • Bigger lens / Move the camera • Collect more data.

  16. How Many Pixels Are Needed? Monitoring 20 PPF Recognition 40 PPF Identification 60 PPF Detail 80 PPF You be the judge…

  22. Megapixel Camera Line • Conventional box • Indoor dome • Indoor cube • Outdoor dome • Outdoor integrated with I/R

  23. I-ONYX Megapixel Cameras: Common Features Frame Rate 2-30 FPS Depending on Resolution Resolution 640 X 480 to 1280 X 1024 Progressive Scan Power 12 VDC Supplied or POE Compression MJPEG Or MPEG 4 Lens Included

  24. I-ONYX MP-950 • f4.2mm / F1.8 megapixel lens • 0.5 Lux at F1.8 • Integrated Mount

  25. Indoor dome camera Lens Included 4.2 mm I-ONYX MPD-955

  26. I-ONYX MPD-955DN-O • Outdoor vandal-proof with IP66 protection • Day and night function with mechanical IR cut filter • Integrated f3.3~12 mm / F1.6 megapixel lens • 0.05 Lux at F1.0 • Surface, flush and wall mount supported

  27. I-ONYX MP-955IR • Day and night function with Mechanical IR Cut Filter • Integrated f3.3~12mm / F1.4 Megapixel lens • IP66 weatherproof • 12 VDC or 24 VAC (POE) • Use V814 AWM Mount

  28. Bottom Line • Vicon 1.3 Mega Pixel Cameras • Three times higher resolution • View larger areas • MJPEG or MPEG 4 compression • 2-8 FPS In Megapixel mode • Progressive scan • POE • Currently electronic iris only • The PTZ and fixed zoom lens is not dead.
