IPC-HDW5231R-Z. It's temp mounted behind a window.
I remember andy saying dahua changed the way they did things, that might make them harder to get lol.
seeing them remotely is a must, and most of the reason I have cameras.yes i remember i got my turrets .now just wait ptzrouter and monitor are on the way 2 more days then will start with VPN so i can see them remotely ...
Clearly getting more pixels on target at the same light sensitivity levels is better. What confuses people is likly the squared / square root difference in pixel to pixel density and the fact that they do not read the light level specifications (assuming they are all done to a standard measurement technique). to double the pixel density of a 2MP camera, you would need an 8 MP camera. If you can buy an 8MP camera with light sensitivity of 0.006 lux or better (lower) for less than the money in your pocket, then you would likely have a better camera for 99% of your viewing pleasure. The 4 MP Hikvision claims to be 0.01lux, which it is not. it is pretty good but not that good. Even with this spec it needs 2x the same about of light (think shutter speed if you will), and there is the DSP clearing things up.

Good explanation.Clearly getting more pixels on target at the same light sensitivity levels is better.

One simple way to look at it is for a reasonably well lit but dim area (say 1 lux), the total light that enters the lens in some fraction of time (say 1/25 sec), either gets divided up to 2M pixels or to 4M pixels. Which one do you think will be clearly presented?
Now if we have a very bright scene, like over 100 lm it is likely that the more pixels on target the better. There are indeed some hours of the year that fall into this category. Getting WDR and shutter speed correct is still needed, but the quality higher MP camera will likely prevail. Here in sunny southern cal i would guess that this accounts for 20% or so of the time in the year and more like 2% of the time that i care about. If i wanted to watch cars go by during the day, i would probably opt for a 4K camera over a 2MP starlight. Good to have more than one camera on target and have the money to get there
It's been 0 for awhile.
the heck are you doing?
, i would like to be able to see machines when they finish i fck hate to go back to work from town just to see machine need 1or 2 hours more to finish hahaha
so would I, should be very easy to do, and totally worth it.cutting stone block in smaller smaller pieces lol
I agree it not a miracle 24x7 solution and that's what I was saying earlier in my other posts.I get all of that. I just think this camera has been sometimes oversold by some as being a miracle 24x7, when IMO its superpowers are mostly at night (and being able to zoom in precisely).
I don't live in a grocery store, but my street isn't nearly as dark as many I've seen posted up. I'm curious how a 3MP/4MP would do here, but not enough to drop the $$$.

There's nothing "wrong" with Nayr's 5231, mine also looks like I'm viewing the scene through a dirty foggy lens during the day.The F2.0 has a larger depth of focus, good for overview shots in the daytime
not alot of difference, IQ seems better on Fixed Lens.. but the Varifocal has taken alot of abuse from the sun being in view.. hope it didnt hurt anything.
Wrong...A 4mp camera will look virtually the same...
Today no news, seems tomorrow can be OK, I will check how many already stock in, because their system freezed around 1 week. Will put on aliexpress stock soon when i have any news.
