If the cameras are mounted on the house, I suggest skipping the wireless option and going for Power-over-Ethernet (PoE).
Drill a small hole to run Ethernet cables to each camera. These cables provide power and data, making them much more reliable in extreme cold. Many PoE cameras are rated for -40°C.

I get it, but how would I run PoE cables to all four sides of the house? Are there better WiFi or mesh options available now?
PoE cables are small and low-voltage, so you could run them discreetly through the eaves or walls.
As for WiFi options, they exist, but many are vulnerable to signal jammers. This has been reported in places like Minnesota and Los Angeles, so security might be a concern.
I recommend Lorex Fusion cameras. In the US, Costco has a great deal on an NVR package with 8 PoE cameras. I use them, and even in winter, they work perfectly (aside from Christmas lights triggering motion occasionally).
The Lorex Home app is free but a bit slow. You can add both wired and wireless cameras to the same app. If you have an NVR with extra channels, you can also record video from wireless cameras. Most Fusion cameras support SD cards too.
A friend in Alaska swears by Axis cameras, especially the “LVE” series for extreme cold. Other brands like Reolink or Dahua tend to fail within a few years in harsh outdoor conditions. Axis cameras last for over 15 years, but they are pricey.
Here’s what I’d recommend:
Avoid their M series; go for P or Q series cameras.
Check eBay or Facebook Marketplace for used models to save money.
For doorways, Axis A-8105E cameras are great. They work as an intercom and handle cold weather well despite being 2MP.
Use surveillance-grade SD cards (32GB should be enough for home use).
Free cloud storage via Axis Edge Cloud is an option.
If you want doorbell functionality, Axis I8116-E is a newer model with object recognition (like identifying vehicles or people). It’s expensive, though.
Pair the cameras with smart locks or a relay for remote door control.
I’ve had this setup for years and love it. My family and I can monitor all four doors remotely via the mobile app, even while traveling.
