Good to hear that! If all stock in we always ship fast, i think after Christmas shipping speed will be faster. In NOV. we can do 3days from China to US, but here can't.
What did you end up going with for your front door camera? I am also considering the 5231 but thinking I may not need the varifocal lense there. I would like something with as wide a view as possible.
you say that now but then you end up being like this guy: Where to install turret camera I'm about to purchase?
for some reason all noobs think they want wide angle; then pretty soon regret the decision entirely.. thats what makes the varifocals so great; that and they have even better low light capabilities over the fixed variants; even if u wanted to run it at full zoom out.. the Varifocals outperform the Fixed lenses by a large margin.
Varifocal Starlights in this lineup have a F1.4 Auto-Aperture
PTZ Starlights in this lineup have a F1.6 Auto-Aperture
Fixed Lens Starlights in this lineup have a F2.0 Fixed Aperture
Bigger the F-Number the less light it will gather..

I am definitely ordering the 5231 after reading everything here, I just wasn't sure if it was the right pick for the front door. Once I get it I will just mount it up and check it out. Just waiting on Andy to send me a paypal invoice so I can get the discount.
and here is a back to back comparison between a Dahua 2MP Starlight Fixed Lens and Varifocal:
Dahua 2MP Starlight MiniDome (F2.0 3.6mm Fixed Aperture)
Dahua 2MP Starlight Varifocal Turret (F1.4 3.6mm Auto Aperture)
Both cameras were configured identically (1/30 Shutter, No Backlight, Gain 50%) and all IR disabled; the only differences between the two cameras were the optics as they are pretty much the same cameras in different housings.

I am throughly confused about what to buy. Based on the insanely good reviews of nayr, it has to be starlight. Now the question is whether to buy bullet or turret. Application is 3 outdoor cameras - one on front porch, one on rear deck under a slight overhang and 3rd on a wall, exposed fully to the elements. Can turrets really be used outdoors? I am guessing turrets would be fine on the front porch but bullets better for fully exposed cameras? Any thoughts are very much appreciated.

Turret are just as whether resistant as bullets... Not sure why you would think otherwise...
Many thanks! I wasn't sure what to think hence the question and usual, your answer is to the point fenderman! Cheers.
Very interesting. On the top video there appears to be a visible seam where the kids toy house is. Anyone else see that or is it just me.
ideally it should be three 60 degree fov @ ~5.8mm but im betting they have some overlap and stitching the streams together, without the video its very hard to even tell.
really wish that camera had a 1080 vertical resolution.

just install all turrets at this point, the only thing the bullet has over this is alarm input for real motion sensors and stuff; thats cool stuff but alot more complicated than just recording 24/7.
@nbstl68, bout ~$600USD.. not bad given cost of 3x cameras in one housing..
On aliexpress below $600 it seems.
The form factor is better than 3 seperate turrets or mini bullit units with 3.6 lens mounted next to each other i guess when looks mean something.
I will consider one for my back garden. I wanted minimptz everywhere, but this 180 degree one for overview, and a multifocal turret at each door for details seems a good way to have nice overview and close enough details when they do try to break in. Support of large ptz from above is also there, perhaps one with auto tracking for the graden only.

looks like the US site got another Starlight Varifocal Bullet in the Super Category: DH-IPC-HFW82A1EN-Z(I)
this has 140dB SuperWDR, and .001 Lux better spec that may account for additional IR range.

What you think would be the reason for theat limited resolution vertically ?
I assume if they stitch the images together they need some pixels to adjust. For example to have the optical path alligned and not to make a too costly hardware setup, and just move it together in software ?
im betting the 4096 wide was the limiting factor; perhaps encoding limitations.
honestly id rather have 3x1080p streams w/no bind spots, more standard. no dewarping easy to work with.

Fixed 4 mm camera's might be cheaper indeed. Will check them out.
Edit:
So the fixed IPC-HDW4231EM-As is like €125 ar BEC store. Empire is more expensive
So to compare:
3x camera IPC-HDW4231EM-AS = 375€
3 x conduit = 210€
3x bracker = 60€
3x cat6 cable = 60€.
Total a out 705€
Andy sent me a PM that is is 640$ so about 625€, and than it needs one conduit 70€' 1 bracker 20€ one cable 20€ = 735€
Well i would need 2 more POE ports on a switch, so total the price shoudl be about the same..
