  • IDK how Frigate handles alerts, but Blue Iris will write an alert to MQTT topic if it matches object recog, and I have an app MQTT Alert that watches that and goes nuts if it comes up. The BI android app is underwhelming in its alerts.

    I’d have to figure Frigate has some sort of MQTT capability. I tried using Frigate but it was pretty basic for my needs, so I moved on.















  • 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.
