We use Arlo cameras around the house where we have wireless internet access. Allows us to see what’s going on and check on the place real time wherever we happen to be. Also gives us voice communication from anywhere we have internet access via phone so if someone is there we can talk to them. Price wasn’t bad, easy setup, and they’ve been quite reliable. Have to charge batteries about 4x/yr.
For the more remote areas we still use game cams. Not real time but at least we know who had been there. Had to call a few neighbors to discuss their activities on our place. They, with one exception that required Sheriff Dept intervention, straighten up pretty quickly with a polite conversation notifying them we have photos of them and their activities.
None of that prevents break ins but it does help to make us a less attractive target. Like a lot of people we didn’t get the cameras or the monitored alarm until AFTER our first break in.
