Does this have to be mounted to the wall or can I set it down on a bookcase that is exactly eye level

Asked by: Mar65
This unit does not need to be wall mounted. I have mine on a bookcase and it's even better if it's at eye-level. The tiny green led blinks one per minute to show it's functioning. At eye level it's really easy to see the blink, if you're looking that way.

Does the unit have to be mounted? The package says portable?

Does the unit have to be mounted? The package says portable?
Asked by: Mary
I guess it could be activated without mounting it to anything, so that would make it portable
