Bandwidth vs Low Light Shootout - Avigilon, Axis, Bosch, Dahua, Geovision, Hanwha, Hikvision, Uniview, Vivotek

By: IPVM Team, Published on Feb 08, 2019

Nighttime bandwidth spikes are a major concern in video surveillance, but do all manufacturers' cameras perform the same? Are some more consistent from day to night than others? And do manufacturer models all similar?

To find out we shot out and compiled results from over 50 cameras from 9 manufacturers - Avigilon, Axis, Bosch, Dahua, Geovision, Hanwha, Hikvision, Uniview, Vivotek - to see how each did, what was average, and who was worst and best and how much performance has improved in the past several years.
