I fully charged the battery 2 weeks ago. The WCO captures about 25 - 30 clips a day. I occasionally check the live feed as well, some days I do not. I do not utilize the night vision. I actived Person detection when I noticed the option earlier this week.
I have a Ring Doorbell camera that picks up 15 to 20 clips a day. The battery lasts about 90 days per charge before I am alerted to recharge it.
