Answer: 
No, it does not. The transmitter works up to 400 ft. away from the receiver. It senses magnetic disturbances & does not need to be in a line of sight with the receiver.

Answer: 
I'd say no, because it works upstairs in a back bedroom where there is no line of sight from one to the other. Hope that helps. My transmitter is in a bush, which has been cut back. This summer I am going to find out if it needs to be trimmed down again or if the bush doesn't affect it.

Rated 3.8 out of 5 by 221 reviewers.
Rated 2.0 out of 5.0 by Not impressed so far... Unit worked fine at first but since has been working sporadically. At the moment it signals when a car leaves our property but does not signal when a car arrives. That isn't very helpful. It may be that when going in one direction the vehicle blocks the signal. Unfortunately need to experiment more with sensor, transmitter and receiver placement. August 22, 2016
Rated 4.0 out of 5.0 by Excellent Product I had looked at different types of these products. Some of the products were motion sensitive. Reviews indicated there were many false alarms. This product eliminates this. I would like to see a higher volume control. It is difficult to hear it at the other end of the house. I place it in the kitchen during the day. Move it near my bedroom at night. August 16, 2016
Rated 5.0 out of 5.0 by Great product This is my second unit. Cut the wire on my old unit. Now I have 2 base units in different parts of the house! Works great! August 16, 2016
Rated 5.0 out of 5.0 by Easy to install and set up. This product was very easy to install and set up. The alarm sound is not too loud and can be heard throughout the house. August 23, 2016
Rated 5.0 out of 5.0 by Excellent product Install instructions were simply, product does exactly what is says it will do August 7, 2016
Rated 1.0 out of 5.0 by Does Not Work I followed the directions for installation, but I have not yet been able to get this device to work. I would not recommend it. August 6, 2016
Rated 5.0 out of 5.0 by Works as advertised.Great! Very simple sensitivity adjustment. Works even better than the "Mighty Mule" company claimed August 2, 2016
Rated 2.0 out of 5.0 by Driveway Alarm This unit is very limited in range. 400 feet doesn't mean much if you have to have a clear unobstructed view. By the time a car triggers the unit it can already be heard and seen coming up the driveway. May be useful in some situation. Save your money and buy a similar unit on line that has a half mile range. Works much better. The price is more, but less expensive than buy one that doesn't work well and then buying the other one. The unit does not have additional outputs for a relay or additional alerts. July 12, 2016
