Optex RC-20U 3 Channel Receiver Chimebox w/ Relay

Excellent product

Bought this to set up another chimebox in the shop at my work. Works great

Works excellent used for 2 outdoor areas. It must be adjusted for distance from door. A few times the dogs trip it off. Great for security.

I have three of these now...they really work great. We live at the end of the road and back up to the National Forest. I have one receiver on the upper floor, one on the basement floor, and that allows us to hear it on the main floor as well as the other two. I have two of the transmitters set up in fake bird houses along the long drive and it picks up vehicles as well as large animals. Another transmitter is mounted covering the width of the rear of the house, and this alerts us to bears on the wrap-around porch. I have this receiver and a fourth transmitter covering the access road to my shop and boat, and this is at my sisters house a mile away. You cant go wrong with these!

Oh, it works great but after a while of the sheep passing by it one at a time it gets kind of old.

Difficult company to work with and impossible to return unwanted item.

have two of the same units --so I new it was A good product

put it by your driveway, back doors, near your car in the driveway and it will wake you up in the night to let you know something is moving around nearby. The batteries in the outdoor sensor last well over a year, though out all temps.

Got it for work, and it works great.

Purchased to notify when someone opened the front door. The alarm actually is in an adjacent building not too far away. We were concerned it would reach the distance going through 3 walls. Luckily it works fine. Simple to install and use.
