Have the set day and night use in. Had on the first night more than 400 recordings, the cameras have then placed on the sensitivity of high to medium and only my dog and people on the monitor. In my case I have installed several cameras around the house (older building, no steel girders installed) and have good reception. The camera is even more than 25 meters across the yard and around the corner but it was enough. On the day very good picture, even at night is still there, I have installed motion lights. I am using the Quattsecure IP Starter very satisfied .. 03/12/2015 P. Schmidt
