这条信息后 就再也没SD的信息了。SD卡休眠时是不掉电的。麻烦大家看下 是什么问题。

4G低功耗摄像头秒级快速唤醒休眠应用方案
一无网无电，应用摄像头，必须需要低功耗！ 在疫情期间，比较有空，所以跟大家分享一下今年必将火爆的一个行业，4G低功耗摄像头的应用！相信很多安防类的公司，都在做此类产品，但是怎么样在产品中脱颖而出，是个难题！ 首先，功耗要够低！这个是产品的卖点，也是亮点，作为一个在无网无电环境下，供电就是靠电池！如果能做到低功耗？其实，关键在于选用的4G模块，我们大家都知道，目前4G平均功耗在30ma左右，这么大的功耗做4G摄像头，无疑是做不了的，电池一下就没有电了，这样的产品投放市场，是失败的！ 所以寻寻觅觅了很久，找到了合方圆的4G低 功耗模块G8100,实测了一下，他们的平均功耗在5ma左右，很理想，功耗
