What are the differnces between the ADC-V520IR and HD100?

A a diifernt note how can the ADC-V620PT not have night vision. Very disapointing.


  • Made by 2GIG
  • PIR motion detection (better at preventing false events in most cases)
  • Costs less
  • Looks/feels a little more like a consumer product


  • Made by
  • Video motion detection (more difficult to prevent false events but can be more acute and flexible)
  • Costs more
  • Looks feels a little more industrial

They’re both good cameras and work well. I use the HD100 more because of the lower cost and the PIR.
