  • Yah, that’s a PWM charger. You’d likely see up to another third more power stored with an MPPT at temperatures below freezing from my experience running various offgrid livestock pumping systems over the years. I still use old PWM controllers on things like fencers because they’re pretty low draw, but I haven’t bought a PWM for years now since MPPT prices came down to earth.

    Just a suggestion, idk what your particular scenario is but it sounds like you’re running out of power pretty quick. And for batteries, I’ve personally moved to LFP with heaters in insulated boxes for the sheer life expectancy, power density and reliability compared to LA in cold temperatures. But I wouldn’t say it’s the cheapest way to do things.


  • Well, I guess whatever camera you get should give you a power requirement and you can work backwards from there as to storage and panel requirement. My off the cuff notion would say you’ll need a deep cycle or a group 31 of 100aH to last for a day or two depending on weather and length of day, and lithium batteries will get plating if you try to charge below freezing so they’re out.

    It’s all in the math, then double it because nature hates you.



  • Grab a regular ethernet connected camera with 12V supply and ONVIF compatible (most PTZ cameras like Amcrest or Vikylon are 12V), and a OpenWRT router like GLiNet’s cheapo units in bridge mode. They have a wireguard VPN active already, you just need to get it set up. Then you specify what subnet the inside of that router is so you can get to the camera, and access it via IP.

    Put down a car battery, a cheap MPPT charger and a panel or two. The PowMr charge controllers have a couple of USB ports on them to power the router and they’re $50.






  • They don’t obfuscate the filesystem, it’s right there in clear folder trees under each username in the chosen data folder with all the filenames you see in the UI, you can do whatever you want with it.

    I hear this bullshit constantly and I go back to check just to make sure I’m not fooling myself and there it is. Where do people get this from, do you not know how to navigate a filesystem?

    I’d have to look at Frigate again, but I’ve used BI for a few years now for myself and neighbors that I’ve installed livestock monitoring cameras for. The phone app is quite good, it does very reliable recognition via Deepstack, it’s compatible with so many cameras it isn’t funny, and the automations are very extensive. Setting up schedules is pretty intuitive.

    The geofencing is terrible, but that’s about my biggest complaint with it, besides having to install it on a Windows VM. I did have it working in Wine years ago, but it wasn’t very stable.

    Make sure any cameras you get are ONVIF compatible. That’ll give you the widest usability.

    And while it’s great to be self-hosted, I’ve never found anything as good as BlueIris for camera software, even if it does cost $50/yr. I run it in a Dockurr/windows container, there’s a few projects out there that make Dockur easier to set up.




  • If you do a zfs list from the Proxmox server command line, you’ll now see a dataset named something like rpool/vm100-data-disk1 and that the second virtual disk in your VM. Now you operate on the virtualdisk however you like, format it with EXT4 or something (don’t use ZFS). It’s still a ZFS volume and Proxmox will be able to snapshot it, replicate it etc, or you could do it manually on the host. But as far as the VM is concerned, it’s a raw disk that you do normal disk stuff with.

    I couldn’t sleep at night if I didn’t have my data backed up in 6 different places. I spent way too many years as a sysadmin to deal with 2 backups.

    ZFS mirrors on my Proxmox server with multiple nodes replicating to each other. Replications of those datasets to zfs.rent. Proxmox backup server taking hourly snapshots and doing it to multiple drives. Rotating USB drives on that PBS server. Backups of the data for each VM and each docker container stack via rsync. Borg backup. Multiple Nextcloud clients with each having their file syncs held locally, then rsynced to a secondary drive.

    I could probably come up with a couple more that I’ve forgotten I have running. I got burned once and it made me mad.
