the turret is alot bigger than the normal version. its not only the turret, you need different mounting brackets... only for 1 model ?
in my opinion even the 5442 dahua turrets are not as good as the bullets.
to my knowledge the bullets have all 4 LEDs and you can set near/far illumination.
turrets only 2 without any near/far settings...
if you need the built in LEDs you will see the difference at night.
also for some reason the vario turret tends to go out of focus for some reason, so need a script for autofocus each day. if your mounting cannot give you reliable autofocus, then good look
