    Great service from Smarthome. I will purchase products from them again. Optex detector installed easily into pre-existing system. No issues or problems. Working as intended.

    Transmitting distance is excellent.
    ERIC -- spokane, WA   4/8/2010
    Works OK. I have another exactly the same as this one that seems to work better. This new one seems to have one side that is lacking the proper sensitivity, but overall I'm still happy with the product.
    CRAIG -- kailua, HI   1/9/2010
    Smarthome ships my orders very quickly and I'm very happy with my products. I will be recommending them to others.

    Very quick delivery.
    MARGARET -- humble, TX   12/28/2009
    Smarthome Service was very good. The product is not as effective as expected. Motion sensing is not sensitive enough especially at longer ranges.
    CYNDAE -- atlanta, GA   11/30/2009
    Great system!!!
    GARY -- sharpsburg, GA   8/24/2009
    Very happy with this product. I didn't expect the range to be as good as it was. But placed beside our driveway (and set to long range) it covers the driveway and half of our front yard, at least 50' and maybe more. The 2nd unit is set on wide range and placed to cover the front door and sidewalk. We had a problem with minor vandalism in our neighborhood, but this product has provided me with peace of mind so I can sleep better. Set-up of the detector and base station was simple.
    BEVERLY -- payson, AZ   2/3/2009
    Fantastic - solved my problem
    DENNIS -- grafton, OH   8/15/2008
    Great product! Working great once I got it set and aimed.
    Tim -- san jose, CA   12/18/2006
    Installed it a week ago on our ranch. Two sensors were installed on trees along a driveway to warn of intruders and cars visiting. They were about 200-ft from the receiver with some trees in between. They have NOT had one false activations. Very impressive. They actually warned us of deer herd moving through that area correctly. All smaller wildlife such as coons, opossum, foxes and smaller pets did not activate the sensors. The receive does not have 1000-ft range when there are trees shielding the receiver. We tried to install at our gate about 800-ft away but the receiver cannot pick up the signal. There is a clump of pine trees about 50-ft thick in between, they may have blocked the signal. The manual was quite clear about this, so we were not surprised. For our purpose, the sensors work very well. Highly recommended.

    The long range Indoor/Outdoor transmitter that I purchased for our farm is great. Since we own a business on our farm and have a major problem with kids trespassing during the night time hours we now know when some one is on our property. Don't know how we ever managed with out it.

    exactly what I wanted
