Any one experience with this Dahua cam, IPC-HDW4421EM-AS?

I was trying to compare it to the IPC-HDW4431C-A (which is similar to the 4421C-A) that many here are using. Looks like the only difference is the 4421EM-AS has a 50m rated IR and a built-in SD card slot vs the 4431C-A/4421C-A's 30m rated IR and no built-in SD card slot. The 4421EM-AS is also listed about $30 more.

It's currently showing not available, http://www.aliexpress.com/item/Dahu...2689673194.html?spm=2114.13010308.0.44.4Sa3yA

Also, Dahua's website does not have any information on the IPC-HDW4431C-A and IPC-HDW4421C-A, but they do for the IPC-HDW4421EM-AS

Ignore the 30m / 50m IR rating. It's rubbish.

You are getting a built-in SD Card slot extra, not worth $30 IMO but might be for some users.

Agreed, esp if that's the only difference. So difficult to find info on these things... Thanks!
 
And the seller just got back to me saying there are no differences between the two... :rolleyes:
 
Yes I think it's same as Hikvision

21 means the "Western Stuff" aka 2xx2, 31 means the "Chinese Domestic stuff" aka 2xx5/3xx5

Buyer beware from that seller...he is very unprofessional resorting to name calling of his customer.
 
Yes has the Micro SD card slot. Compared to my other camera which is an IPC-HDBW4421R-AS it was much harder. I had to unscrew the board which had the camera lens attached. It was quite fiddly holding all the bits while I put it in. Saying that it still probably only took me 5-10mins to install the micro SD Card.

Based on g_phill's other thread, the Eco Savvy 2 (4421EM-AS) has a metal base, similar to the Hik's base where once you lock them down, the camera isn't moving anywhere. On the Eco Savvy 3 (4431EM), the base is plastic and the camera can be moved with little effort, even after its been secured into the base.

I took a look at Dahua's catalog, thanks GuitarKin for pointing it out, a noticed the lux rating on the Eco Savvy 3 turrets were much better than the 2's (if we trust the listed ratings).

Then I also noticed they have a "starlight" version: IPC-HDW4231EM-AS but was not able to find it on Aliexpress. This may have already been discussed here, but it's late and I haven't searched yet.
