Hi everyone, I'm a newbie from China

I have been monitoring this area for a long time, and found a track of a badger and a civet cat. I have placed my camera for a week, but nothing has been photographed.

Welcome to the forum. I'm looking forward to see the results of your camera trap. What camera and motion sensor are you using?

Today I found that there is a very weak electric sound after turning it on. I don’t know if it will affect the animals.
