Super Low Lux Geovision Minidome Tested

Author: Derek Ward, Published on Apr 10, 2014

'Super' low light cameras have become increasingly common in box and full size cameras. However, no one we know has offered them in a minidome, the most common form factor for many users, valued for their small size, aesthetics and low cost.

Recently, Geovision released its Aurora line of 'Super Low Lux' cameras. A member alerted us to this promotional video:

He asked whether this was too good to be true. Were these claims simply manufacturer marketing hype?

We bought their GV-MFD1501-1F minidome, a 1.3MP, 1/3" imager camera and put it to the test against leading minidomes from Axis, Bosch, Dahua and Hikvision to see if Geovision was telling the truth and whether it could match up against them.
