Mailboxes face the street, away from the house. Ours is in a brick column. If "line of sight" is important, will it work?

Yes... Line of sight actually is not required. This is a radio signal that will defract and bounce. It will attenuate some with dense materials, but mainly the low power will limit distance. Mine works over 35 yards or so.

It should just make sure you follow the directions.. the brick should be ok.. concrete I would not be absolutely sure..I taped mine with duct tape to the face of the box. And made sure the antenna had breathing room to the LOS to the home.. Had some crooks stealing mail in area.. and I noticed 2AM the light came on.. we had nothing in the box but they tried with Valentines day near.

Vertical placement seems to work best, but if horizontal, aim the sensor end of the bulb toward where outside visitors approach from, is my guess.

The privacy screen does not completely block the view of the old cars on the other side of my chainlink fence. When the sun is just right you can see right through it. Would not work for a "peeping neighbor" situation except when the sun is on your side. It really depends on the location of the sun.

Absolutely. Mine is a large standard metal box, about 200 feet away from my house. Works flawlessly.

It should, as long as there isn't any metal in the walls, like rebar. I can't try it, but I have a radio/radar background, and plain cement block doesn't interfere. In our house we have a set between the bedroom at one end and the kitchen at the other end, 50 feet away through several walls, and it works fine.

Make sure there are no large metal objects between( line of sight) the two units. The metal object could be a refrigerator inside the house or a car parked outside. Also, the mail box itself can block the signal if it is metal. I had to extend the antennal wire on the transmitter a few inches outside my metal mailbox to cure intermittent operation.

If you have an electric drill, you could adapt it. I had to make some adjustments on my mail box, but once installed, it works fine. Saves me a lot of useless trips to the mailbox.

Well, the unit itself cannot, but the radio signal that it uses will make it through with significant attenuation. The unit was designed to work its best with a line-of-sight signal path, but if you can tolerate a much reduced distance, it will work with obstacles in the way. DON'T count on much signal getting through a metal barrier like aluminum or steel siding.

Our front yard is 2/3 acre, our house is brick with double paned windows, our mailbox is across the street, and have no problems with signal reception... We've had it less than a year and don't know how it will work during Winter months, but I don't think any issues will arise.

We are out of US and have concrete walls other systems would not work. We have doorbell button mounted on thick wood gate which is 40 yards away from the receiver. The motion detector is about 35 yards. They work great together and currently we are waiting on another receiver that someone is bringing to us to be able to put in another location so we can hear it by the back pool. We tested the first receiver and it went that far throught the solid block walls - 60 yards

No. Our mailbox is about 80 feet from the receiver and the signal has to go through two walls and a metal garage door.it works great. We love this thing.

In my case, I think that the metal mailbox shielded the signal from reaching the house. Perhaps it would have worked had the house been only a few feet from the box.

I have one of my camers located outside behind a security gate at my front entrance. My receiver is located in my master bedroom which is about 30ft away. My house is Hardy Plank and I have no issues with the picture. As a matter of fact, it will pick up any bugs flying in the entrance way at night without any light. I hope this may help.

it needs a direct line with no obstacles between it and the dog. It worked great when mounted flush with a wood fence and I bored appropriate-sized holes for the sensor and speaker to pick up the barking clearly and respond with the ultrasonic sound to a neighbor's nonstop barker. It was mounted about 20" from the ground and was pointed into their yard, where the barker resided most of the time.

It all depends on the construction of the buildings. The instructions advise against placing units in different buildings or in unheated spaces. My basement unit will network with the ones on the second floor. By line of site, they mean an electronic signal must be able to make it. The units don't actually have to be optically visible to each other.

It should....we used to take ours to our neighbors house for Bon fires on the weekends and never had an issue with range. We were obviously outside so it only was going through our house walls and our sons room was on the side of our house closest to our neighbor so that helped. Going through 2 sets of walls will reduce the range more than 1 set, but I'd definitely try it, if it doesn't work, amazons return policy is great!

It can be hidden, it does not have to have a direct line of sight. It actually has a pretty good range.
