So thought I would also post important info for anyone that might be thinking about using IPA it's very flammable and Toxic and if you don't use correctly it maybe harmful to your health. I use a fume extraction system and Nitrile gloves.

While I have this black one apart thought I would show my lens, now while I may have said irc these cameras use ICR and are interchangeable so from time to time I might call it what I last remember seeing lol, anyway the ICR lens holder you can see 2 screws that is on camera board side as normal but that is what I was talking about, after removing camera from the connecter plate, 2 screws the ICR comes up from PCB and exposes the sensor. Then install good unit put in screws and no need to worry about trying to get the lens out of holder seeing they are glued in. Trying to break the lens free might break the housing. Plus lens would need to be set for focus. Me sending ICR and lens complete it's just remove and install no adjustments needed. Would just send whole camera PCB but already used a few parts from the PCB to repair a couple of other cameras lol...

Thank you for the offer and comprehensive follow-up. Been very sidetracked and apologize for the delayed reply.

I'll be back with an actual response when opportunity permits.

[Revo2Maxx]

No need to apologize, Life is what life is and everyone needs to live life outside the forum. Just wanted to post some things for others that might follow the thread..

Something I thought I might mention, 99% isn't always needed for everyone and for others that don't live my life lol may not need to worry about buying 99% as you can source 91% from big box or other places. Mine is from 2018 and this is the last bottle of 4 that came in a box. If you happen to have 99% and didn't know you can dilute it to make 91% and even lower, Normally I do 12fl oz of IPA and 2teaspoon with 2 tablespoon of Distilled water is around 90% and is what I use most days for most projects.. I have some other that I use for different type of flux and something people need to keep in mind is that the Potency over time can dminish, Alcohol evaporates before the water will and on a 70% that was exposed to the air over time and is what happened to what I used the first time I tried to clean my cameras. Now the last picture is the first camera I tried to clean and it was much worse then the first black camera I posted the picture of. Leaving the cap off the 70% for upto about a day could have dropped that down to around 50%.. IPA is most effective between 60 and 90% as a disinfectant. 70% IPA and electronics require longer drying time and can cause corrosion if it isn't fully evaporated before powering on a device after cleaning. So using 90 to 99% is best because of faster drying time and minimal moisture residue. Again might not be useful info to everyone but others again that might be following along might benifit from the info..

Do you by any chance have the specs on the clock battery? I need to replace it in one of my cameras. Thanks!

[Revo2Maxx]

@SpudsMac Hello and Welcome to the Forum.
This is the battery this is on Ebay I don't know them never bought from them and don't endorse them. I am purely showing you the type of battery and after taking one apart by pulling the plate that was spot welded on the battery off so I could see the whole battery + side. That battery can be found on Digikey as well however it seems they have a different solder pad setup then the one that is in this ebay listing that we need for the cameras.. https://www.ebay.com/itm/232282460193
Or if you prefer Alibaba you can find it here.. https://www.alibaba.com/product-detail/ ... 76045.html

Well now I know what type of battery I need and have source lol. before I was just using a 3v pack style seeing I couldn't find at the time any batteries that fit the one I had removed last time.. All I could make out on the battery case was 3v and Japan. Looks like the battery is a 3.3v

Also keep in mind this battery is Solder on and the area where the battery is placed is on the other side of the PCB. So would need to take off bottom, Remove 1 scew that hold the PCB and 4 connecters 2 for motors 1 for mic and other for Camera, then the battery would be on the motor side of the corner very small soldering area, I used a Hakko K tip and the side connected on the motor cut out side is larger area then on the other side so it is easy to access if using the right type of soldering hardware. If you have a hard time you can peel back the top spot welded plate back to make it so only 1 area is contacting the PCB to make it easier to remove the SMD battery..

Here is a few pictures, 1 of the current 841 with top peeled back to gain access to the battery marking. This time as I said the camera has more then the others that I replaced. This is one of my newest 841W from 2018 Sold in 2019 seeing the motor date is 11-29-2018 so by the time it was built and put for sale would have been 2019.. Anyway after peeling this one back it was clearly marked you can see in pictures.. I also posted 2 pictures of my hakko tips, 1 the K that is better for moving the battery and the other my most used BC2 tip to show why the Knife tip is better.. right click view in tab to see full picture

Also word of caution. If you look at the last picture where it shows the white area of the battery ground side. That whole white area is the ground, So when you flow the solder on the + pad you will want to make sure not to over flow it because the area between the 2 is really close.. I will show a picture of what the battery looks like without the battery just the 2 tabs..

Cool to come back to all the new pics and info. Well covered and nicely done, Revo.

So a week after the alcohol (91%) treatment has had time to set (or dissolve things) I'm happy to report zero new visable goo or residue. Still nice and clean and shiny.

After playing around with the firmware (and updating to 2019) I'm pleasantly surprised at the capabilities of the little rascal. I was happy with the early firmware but it wouldn't retain 1080p or 30fps settings. Showed as saved and worked at the desired settings but reverted to 720p defaults after just exiting the menu to do something else and/or an exit. Same with immediately rebooting after setting everything to 1080 and saving accordingly. Back to 720 after reboot. (Yes. I did a couple factory resets with no change in the behavior.)

I seem to recall reading somewhere that the latest firmware could be problematic so opted for the 2019 verion right before it. Unfortunately it exhibits the same problem. Haven't experimented with the various 1080 config permutations and it may well be a restriction/limitation imposed somewhere there, but 1080/30fps/4096bps/CBR/1sec I-frame (value of 30) seems pretty vanilla to me. Any tips there would be welcomed.

As for the lens, I'm certainly game for swapping it out as the image quality defintely suffers with the current one. PM inbound to make arrangements.

Thanks, man.
