For thick walls and weak home Wi-Fi, a dedicated non Wi-Fi monitor is usually more reliable through walls and better for privacy. Wi-Fi models depend on your router and can lag or drop at the edges of coverage, especially outdoors.
I recommend 2K 3000ft with a claimed 3000 ft range and a 6000 mAh battery. Night vision is clear enough to see movement and day to day the direct link stays connected without app hassles.
i'm with you that for older homes with thick walls and spotty Wi Fi, a non Wi Fi monitor is the safer call for reliability and privacy. That pick fits your setup because it uses a direct link instead of your router, so it stays solid through walls and when you walk into the yard, with no app lag or random disconnects. We're in a 1950s place with plaster and lath and it behaves exactly like that day to day. Battery life comfortably covers naps plus evenings without babysitting the charger, and the night vision is clear enough to see breathing and small movements so you know whether to head in or let them settle.
