No, its not that sensitive. The cameras react only when there is significant movement - you can change the settings to the level of sensitivity you prefer. This makes it better for pet owners such as myself since our dog would always trip the camera. Not entirely sure how it works but our dog wont set off the camera but my 3 year old daughter does. Ours are also linked to our sensor lights too so all the outdoor lights come on if there is a disturbance.
