Adimec on Smaller Pixels in Security

Adimec blog's recent post discusses the benefits and issues of using smartphone-style small pixels in 24/7 security camera applications. The pros and cons of small pixels are:

  • Lower costs and weight through smaller sensors, optics, and cameras
  • Increased resolution with same sensor size and optics
  • Sensitivity in dim light is acceptable
  • Color reproduction can be good enough

  • Give up global shutter (get rolling shutter)
  • Slower frame rates
  • More noise
  • Lower full well capacity
  • Lower MTF
  • Optical/Electrical crosstalk
  • Lower quality available optics
