I WAS going to purchase 4 more cameras but Wyze going back on their original 12 sec, no subscrip promise, makes me wonder what other promise will they next break? IN ADDITION, current saved events delivers audio / video out of sync. It makes me doubt snap shots taken at event trigger, will be useful. Don't know how, or if, I'll be able to incorporate the 4 cameras I already own into a useful on-site system.. Regardless.. No subscription was promised with 12 sec video...
