I saw this for $109 on amazon awhile back, but haven't seen any mention of it here, yet.



I asked on the amazon page ,"Does it support RTSP and ONVIF?" and a month later, Amcrest Support replied, "Yes."

So now this is interesting. "Featuring the latest Sony Starvis CMOS progressive scanning image sensor (1/2.8")" this is supposed to have better night vision than its predecessor.

I don't need the megapixels, so if I were to run this at 1920 x 1080 (e.g. 1/4 of the native 3840 x 2160), does it bin each 2 x 2 pixel set and give me 4x the sensitivity and/or 1/2 the noise? Or does it crop down and reduce my FOV?

I would be running this out of BI, so the AI and detection features, etc., also are not really of interest to me..

But I'd like to know if it's a worthy upgrade to the $50 - $55 IP5M-T1179EW cameras I've been buying for the last 2 years.

No, these sensors don't bin pixels. You just end up with lower resolution on the same sensor with whatever capabilities as far as sensitivity. With a 1/2.8 sensor @ 4K the 5MP that you have probably are as good or better at night.

Downrezing a camera does not work - It is still using the 8 million pixels - the camera doesn't change the "pixel resolution screen" on the camera when you go from 4MP to 2MP. The sensor still needs 4 times the light going from 8MP to 2MP, so the native 2MP camera will result in a better image at night. The firmware will make some algorithm attempt at downrezing it, but it could be a complete crap image or a somewhat usable image, but if there is a concern that the 4MP isn't performing or wouldn't perform well at night, then it is better to go with the 2MP.

Your existing cameras would perform better at night. And it is probably similar to the Dahua 4K TIOC that is nothing but trouble.

Lot's of threads here where people showed how bad the Dahua 3849 camera is in performing even during the day:

IPC-HDW3849H-AS-PV issues
I put this guy up and for some reason, and I can put my finger on it, this picture just looks strange. The grass kind of looks like digital or something. The camera is on the default settings but I feel like I have tweaked most of them. Any suggestions? IPC-HDW3849H-AS-PV is the camera.


IPC-HDW3849H-AS-PV loses connection/reboots during the day
I have a IPC-HDW3849H-AS-PV (8MP, Full-color night, 1/2.8” CMOS (3840 × 2160) @20 fps). I also have several IPC-HDW5831R-ZE, IPC-HDW2831T-ZS-S2 , and IPC-HDW4431C-A. The IPC-HDW3849H-AS-PV disconnects and reboots during the day, I have no issues during the night. It's my only cam that has this...


Replaced HDW5442TMP-ASE by HFW3849T1P
Hello everybody! I replaced my favourite camera HDW5442TMP-ASE with new HFW3849T1P and I came accorss that HDW5442TMP-ASE has much better picture than newer one. I replaced it because HFW3849T1P 8MP instead of HDW5442TMP-ASE 5Mp and HFW3849T1P is TIOC (three in one camera). I didn't expect so...

IPC-HDW3849H-AS-PV Video Quality
Hi All, I have recently installed Dahua IPC-HDW3849H-AS-PV, 2.8mm (8MP, full color, active deterrence) cameras. The overall video quality is good but I cannot read number plate for cars passing down the road (approx 11 meters away) or identify people properly. Is it the expected behavior? What...
