Cam battery suddenly drops

We have three Outdoor Cams and a base station.

Several times one of the batteries suddenly jumps to zero. Others seem to lost charge rather quickly. I wantbthem to stay up at least a week so I can mount them high.

Today after charging them all night I set them up and disabled motion detection, seeing if they would hold a charge longer. For a while they seemed to stay in the high 90s. Then one dropped to zero and the others dropped to 44% and 26%,

Any ideas? I can’t live with this kind of erratice battery performance.

Could it have anything to do with the oitage at Wyze?

The cams are on WiFi to centralize the signal.
