I have purchased 4 Tapo C425 which are supposed to be the best in the range battery operated , but they are totally useless , beyond 3 meters they do not detect anything , an elephant may be dancing but if it is beyond 3 meters it is not detected , my old blink xt2 detected even up to 7 or 8 meters movements . I wonder what good are cameras like this if , as happened to me , there are intruders but they are not detected.

I have already set all the sensitivities to the maximum , wake-up sensitivity to 10 , motion sensitivity to 10 , but nothing has changed 

So I ask Tapo engineers directly , why not improve the detection ? As it is now it is a totally useless camera as a security camera because it does not detect anything , maybe it could detect if it steals or the camera because they are so close
