I tried the Harbor Freight device, over this past weekend, and it was a complete and utter fail. Now I got to go back and hopefully just get a refund. To get there is another city in another county.
Failed:
> 6vdc input to run it off of a wall wart transformer - total fail despite trying several different transformers.
> 400' range? ha.
I couldn't get it to respond across the rear of the house, at 25', clear open eyesight from sensor to receiver.
It would not respond in another direct line of sight from perhaps 100' away when I tried it on the front of the house, as a driveway dinger, and with an object as large as a moving car. In this instance, I mistakenly thought that it might be able to broadcast signal that distance, and through a single pane of window glass.
Failed.
