I started here: Panasonic HomeHawk Indoor Wireless/AC on sale for $70 in Nov 18 at Costco.
After reading a lot of customer reviews and product comparisons I could see that no low-end option was going to be perfect. Full “wireless” required recharging batteries periodically - but battery-powered cameras didn’t do detection zones… like that.
Wyze was the hot upstart and the thought was “if there’s no perfect solution, if each will require compromise and troubleshooting/adaptation of some sort, three-cameras-for-the-price-of-one to experiment with is an easy choice.”
