Anybody seen/used these - seem to be new for 2019/20? From the "Lite" starlight range.

How do they compare with the 2431 4MP or the older 2MP starlight?
Presumably they are at least somewhat better than the Chinese market HDW4431C-A, HDW4433C-A or HDW4631C-A with their 1/3" and 1/2.9" sensors?

Datasheet for IPC-HDW2531TM-AS-S2: (or from in French) which claims:
20fps @5MP; 25/30fps @4MP
H.265 and H.264
0.008 Lux @ F1.6
With IR LED ("30m")
Metal casing
PF130-E or PFB203W mounting

Appears to be a western-markets model so should be firmware-upgradable and compatible with latest NVR firmwares?

Any ideas what (if any) differences would be between the normal and -S2 variant?

Don't follow the megapixel bandwagon. The 2mp and 4mp Starlight cameras frequently discussed on this forum are the way to. You'll spend a little more extra, but at the end of the day, you will be happy with the decision made
 
Maybe not everyone cares much about the night images.
I have talked to my neighbor, who has a Cosco kit installed for a while, and he wants to upgrade to 4k. I have recommended him these Dahua cams and he replied, that he cares only about day time images.
 
That's kind of like saying I only drive my car during the day so why do I need headlights. There will come a time that good night vision will be important to your friend and he won't have it. Murphy says so, and Murphy is always right.

The thing is that he is an LA cop.
 
When he will need some footage, he will come to me ;)
 
Even so, there'll come a time and he'll need that night vision and won't have it. Now he can alleviate that problem IF he uses some external IR illuminators. That's kind of a bandaid solution, but will help provide much more reasonable night vision. Personally, I'd say to spend the extra bucks and got the the 5442 series from Dahua.
 
That is what I have told him, but most likely, he is stuck on the pixel bandwagon. 4K is the king, right?! good marketing.
 
Take him to Best Buy. Show him a 2K and a 4K picture on a TV and ask him to identify which is which. Bet he can't see a difference. He's hung on 4K because it's the "latest and greatest", I have a SIL like that. I have convinced him the megapixels in cameras, that us normal mortals can afford, aren't worth chasing. You could also ask him if he's producing a TV show or movie or is he trying to find out who did what.

Relay to him how much MORE storage the 4k will require.
Send him this to read: Cliff Notes

The kicker is, that he is familiar with BI. And he still purchased an all in a box unit.
 
His argument is, that these days they (police) have a very good facial recognition software. He needs a good image and with that, they can find him/her.

I'm guessing that he works days so isn't concerned about getting a good image at night because he'll be home to deal with it personally.
 
Yeah, if he can either see it or hear it. Plan that's bound to fail, plus I'll bet he stays home, all night, every night and never goes out at all just waiting for something to happen.

------------------------------
My standard welcome to the forum message.

Please read the IP Cam Talk Cliff Notes and other items in the IP Cam Talk Wiki. (read on a real computer, not a phone). The wiki is in the blue bar at the top of the page.

Read How to Secure Your Network (Don't Get Hacked!) in the wiki also.

Quick start
1) If you do not have a wired monitored alarm system, get that first
2) Use Dahua starlight cameras or Hikvision darkfighter cameras if you need good low light cameras.
3) use a VPN to access home network (openVPN)
4) Do not use wifi cameras.
5) Do not use cloud storage
6) Do Not use uPNP, P2P, QR, do not open ports,
7) More megapixel is not necessarily better.
8) Avoid chinese hacked cameras (most ebay, amazon, aliexpress cameras(not all, but most))
9) Do not use reolink, ring, nest, Arlo cameras (they are junk), no cloud cameras
10) If possible use a turret camera , bullet collect spiders, dome collect dirt and reflect light (IR)
11) Use only solid copper, AWG 23 or 24 ethernet wire. , no CCA (Copper Clad Aluminum)
12) use a test mount to verify the camera mount location. My test rig: rev.2
13) (Looney2ns)If you want to be able to ID faces, don't mount cams higher than 8ft. You want to know who did it, not just what happened.
14) Use a router that has openVPN built in (Most ASUS, Some NetGear....)
15) camera placement use the calculator... IPVM Camera Calculator V3
16) POE list PoE Switch Suggestion List

So is this AMCREST the re-branded version of the OP camera?
I wonder if the Dahua firmware of the OP camera will work on this.
