With a driveway that is over 300’ feet long it’s a little difficult to hear someone pulling up to our house until they are literally at our door. Even in the boonies we sometimes get unexpected visits, so it’s nice to know when someone is on our property for safety reasons.
To solve this problem, the hubs purchased a wireless battery operated system with a range of 300-400 feet. He attached the sensor to a tree along the driveway. Unless you’re looking for it, you don’t even notice it when you drive by.
The base unit sits in the office window, where it gets a good signal from the sensor and can be heard throughout the house.
Now that we’ve had the system for a while, the dogs have figured out that when they hear the chime it means someone is coming, which prompts them to either stand guard at the front door or dash out the doggie door to investigate from the fence line. Needless to say, if someone ever planned to sneak up to our house and break in they’ve got a crowd of fur expecting them by the time they get to the porch!
The one downside to the system is that it just senses movement, but can’t distinguish what kind of movement it is. So when the neighborhood moose wander through the yard they sometimes come close enough to trip the sensor. Guess that’s just life in Alaska.
