Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

[nayr]

they are the same cameras; there is no such model as an s2.. those numbers are only seen on Dahua CVI (analouge) systems; the seller is incorrect, probably confused.

Thanks Nayr.. always the reliable source of accurate info.

firmware different, this S2 using the Oct. firmware. No big change. The first guy get the camera is S1, seems i only sell 1pcs for this one, others all S2.

 

[nayr]

When in doubt always check out the Dahua Naming Convention wiki page, as you can see the S2 suffix is not used on IPC's, only the HDCVI NVR's..

might as well give up my sources, its not like I know all this stuff.. I just know how to find it all heh

guess your right; double checked my picture of the label on the camera in the first post and it does say S2, never caught my eye.. mebe they print the shipped firmware revisions on the labels.

i was right about em being same cameras at least; but I can admit when im wrong.. I do it from time to time.

Thanks to Nayr I bought two of these cameras. $169.19 each with free shipping via DHL. I used the mobile site to get that price.
BEC technology was the seller.

I have been meaning to ask, do both of the IR LEDs get used at the same time, or is one a wide angle and the other narrow so the camera can switch between them depending on zoom level, like a lot of PTZs do?

Correct, please use the APP, then more discounts.

no it does not; both are always on.

 

[hotwire]

Is there a setting in the software to turn off the IR if you don't want it on?

yes of course, I didnt mean to imply the IR is always on 24/7.. just its always on depending on zoom level in response to his question.



and of course its always turned off when its in color mode and the IR Cut filter is in place.

I want to buy this camera sometime. If a 3A IR illuminator is placed a few feet above the camera, will peoples faces be "whited out" do to the bright IR light? I will keep the IR beam parallel to the camera to avoid blinding the camera, but how far away should IR illuminators be away from the camera?

Reading (lurking) through this entire thread, and I think I'll be returning my newly purchased 4MP Dahua (IPC-HDBW4431R-AS) for this 2MP one. So weird to say that...sounds like I'm taking a step backward...but you can't argue with the comparison footage that @nayr posted. The night time clarity is really amazing!

Now I'm just waiting for Empire's store to be back in stock.

My suggestion is not to buy those models can't search on dahua official website, because all these cheap models selling on Aliexpress. Firmware can/t be updated.
I always tell our client for this if they buy this kind of cameras, but if they no care for this, then also can use well.

Nice!
I'd been wanting varifocal turrets just b\c I'm new with this and was not sure what focal length to buy for different situations. So this would make it an easy choice. 2.6-12mm means I could use this one camera model pretty much anywhere I'd think.

You mentioned buying the bullets above...I've read a lot of pro\cons on this site about the various types and it seems bullets get the least love.
That said, what situation would the bullet version be a better choice, or do you just want it to test for the heck of it?

Have you done any tests at full zoom to see how much that might affect clarity?

I have a large junction box with multiple bullets mounted to it; it wont take multiple turrets without making the box much much larger.. I also am using external alarm inputs/outputs hooked to security sensors to trigger alarms.. turrets dont come with external alarm hookups..

since it uses optical zoom, it has absolutely no impact on image clarity when zoomed in..

Wonder if the starlight cameras would be helpful at night for license plates ?

 

[nayr]

i cant possibly see how; license plates are plenty bright at night.. the'll just be brighter with a starlight.

you can only read plates at night with a camera dedicated to the job.
