when i lived in a city i had a cam and mic along with a speaker. i could see and hear them and they could hear me. just looked at the display and told them to go away. if they took to long the sprinklers somehow came on. if it was a salesman, i never said anything....just the sprinkles would somehow turn on. the :banghead: timers. always coming on with people at the door, also need to fix that one sprinkler head right by the door, as it sprays the doorand walk way, not the plants. now that i live in the hills a long ways from paved rd's nobody bothers me. .
