I have the wireless day/night, B/W monitor w/ sound. Everytime someone walk between the monitor and the camera (Otherside of the wall, in the attached garage) the picture flutters. Same thing happens when any R/F device starts. Like a vacuum, cell phone, cordless phone, etc. Both units have to be plugged into 110v. Maybe I'd be happier if the camera was waterproof, and I could mount it outside, but it'd still need 110. Overall, I'd give it a 4 out of 10. Maybe I should cut in a window.....
I also have one of those driveway alerts that beep. That works about 60% of the time.
For the pole barn, I think it's out of the question. Too easy to look up and see lights if I had a window. If the lights are on in the shop, then the passer-bys would see it the light shine through. Again, too easy.
You have to remember who you're dealing with here! I'd forget to chage the stop light thing, and guys would pull in when I'm snuggled up to the wife in bed!!
DOES ANYONE HAVE AN EXTRA RADIO SHACK WIRED intercom? I have an old one and 2 newer ones. I need one of the newer ones. They have been discontinued, and all use wireless. I hate the wireless. Its based on your power source. My shops are on a separate power source than the house.
