I've been working updating the cameras in S7. I've been messing around with them for some time and have finally decided how they should be set up:
Place up to 3 cameras and activate the viewer. Clicking the attack button activates the cameras. Holding the attack button down switches between them.
Note the red circles when the cameras are placed. These show the area covered by the motion sensors. The only thing I don't like is that you get overlapping messages when more than one camera senses motion. I need to figure out how to have more of a delay between messages.
Oh and forgive the font used for the text - that's from Fables which I haven't gotten around to changing yet!
