Axis Laser Focus PTZ Tested

Author: Ethan Ace, Published on Aug 14, 2017

Axis has been touting its new Q6155-E laser focus PTZ as 'always in focus' and 'always in color'.

Does it really deliver?

We bought and tested the Q6155-E to see how laser focus worked and whether this "flawless focus" was all marketing hype or offered actual performance gains, testing in:

  • Low light (3-5lx)
  • Dark (0.3-0.5lx)
  • Day (4000+ lx)

Actively tracking a moving subject across 500'+ range.

See our full results and recommendations inside.
