Door bell D230 cannot draw difference detection zone
I have two C420 outdoor cameras and one D230 doorbell. C420 is very good and allow m to draw difference activity zone on the screen to setup difference zone like person and motion (photo 1). However, for the D230, it only allow me to draw a motion activity zone. I have no option to draw the person activity zone to separate motion and person activity zone (photo 2). I only allow to select enable or disable person detection but can't draw it. If I select enable person detection zone, it will be full screen. May I know how to draw difference activity zone on door bell like outdoor camera? Thank you.
