IP2M-841B firmware 2/17/20 update problem

Post by sgrayban »

So I just got my new IP2M-841B from Amazon and tried to upgrade the firmware. I downloaded the version V2.420.AC00.18.R 2/17/20 which says on the download page that it is for the IP2M-841B, IP2M-841W and IP2M-841S V1 & V2

firmware filename - Amcrest_IPC-AWXX_Eng_N_AMCREST_V2.420.AC00.18.R.20200217.bin

When I try to upgrade it throws a error.... File unmatch, Upgrade failed! Some functions have been closed,reboot device now?

I have downloaded the file 3 times are all 4 times it does this. Any help?

Hello and Welcome to the Forum

Are you sure your using the right device? This don't happen if your using the right machine..

Well I then see that you said you get this from Amazon.. That might be first issue.. Heard they can do some funny business and sale as new when it wasn't

So please report back what your Camera info looks like right now? Like one of my cameras that still has on older FW looks like this


Software Version 2.520.AC00.18.R, Build Date: 2017-06-29
WEB Version 3.2.1.453504
ONVIF Version 2.42(V2.2.2.428697)

Here is what one of my 2019 that is same type of FW as the 2020 your trying to DL looks like

Software VersionV2.420.AC00.18.R, Build Date: 2019-08-03
WEB Version3.2.1.619604
ONVIF Version16.12(V2.4.1.513183)

These are both the same type 841 cameras just different FW installed in them

I don't think this camera has custom FW just for Amazon. Now this is a IP2M-841B NOT IP2M-841

This is what I have...

Software VersionV2.800.0000000.1.R, Build Date: 2019-09-27
WEB VersionV3.2.1.794592
ONVIF Version18.06(V2.4.5.782676)

It looks like your Web/ONVIF version is older then mine though even with the update....

Sadly that is the issue...

Your 841 isn't an 841 at all.. it is A V3 841 and is on a different Hardware platform..

That is why the 841 software you trying to install isn't working

Notice the FW numbers in my listing that is for the 841 by the way B W and S mean nothing but to confuse you and others that just means the color of your unit.. I don't use B S or W most times because it mean nothing...

What means something is that your unit if you look at the Back has no Alarm in or out ports and no Audio in and out ports that is because the 841B your talking about is a 841B-V3 you will want to make sure that your trying to install V3 FW and not normal 841B, S or W v1 or v2 FW looking at your VER v2.800.000000.1.R is a First Version software for the Camera it is installed in Sadly the 1.R for yours might never change as they stopped doing FW numbers in order of being able to track the version of FW update.. Mind you the 841 has been out since 2015 and before maybe but the oldest one I have is form 2015 and when the first FW came out for it that 18.R that is there now was at one point a 1.R as well and might been even a different number before because I updated a 1.R from 2015 however I had a older then that camera bought used with different FW already installed pre dates my 2015 unit I can tell by SN and by Mac Number

Anyway just so you know Sorry I said 841 as that is just short for any 841 V1 or V2 I even have a 841 is while it is a B it is Special because it would matter seeing it is a EB and requires different FW from normal 841B, S, or W..

Black B
White W
Silver S

Black EB is POE Version Not really Special just mean DIFFERENT as it is POE NO WIFI

I asked them about it and some of the file names that was listed from older version even though the new one was able to be DL last Friday and was looked over and fixed for most part before they went hope Friday so yes the V3 2021 FW is now online again. So not sure if there was an issue and server was restored to some older state or what the issue was but current fW is listed right now..
