CCTV - Ubuntu Server with VRC7016 Capture card

So a lot of this info will be old but good for reference, I did get this project to sort of  working version using bt878 on ubuntu 18 and another server using ubuntu 20. I say "sort of" because most of what I got back from the video was distorted showing a green over most of it and I believe was from a bad board. That might have been why I got it so cheap and it was a non-returnable item through eBay. However, it was enough to see an example of what's possible with old computer boards and cheap cameras. I have since moved onto IP cameras and a lot of what I'm doing now is localized as well as working in 4k. Still I had a lot of fun working on this project.

Commands:

v4l2-ctl --list-devices

Other Ideas 

I had plans to make this project work across my desktop using x-11, but because the images/video was distorted it didnt make sense for the effort. Also was looking into make it work with ZoneMinder..

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable. Make sure port 27017 is open. Then check this  linux - Connection refused to MongoDB e...

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
