  • More Info

    The twin beam, adjustable beam interruption time and automatic sensitivity adjustment of this unit minimize false alarms. The sensor will even work down to the point where 99% of the beam strength has been cut due to poor weather. Mount above pet height level and your pets can roam without setting off the alarm. Mounts to 1.66 diameter poles with included clamps or to any flat surface with screws.

    Additional units may be purchased to create an invisible barrier around your entire property. Wires may be shared (see the manual for details and limitations).

    Product looks good (well constructed)from a cursory glance. Instructions are written in the orient I guess...grammatically challenged. I'm an electrical engineer by trade and though I would have no problem setting this headin device up for practical use, I think the average user would find the set up challenging. You'll need to do a field set up for detector (alignment), find a 12vdc power supply, run the alarm output to a suitable notification device... otherwise not bad. It would be great if Smarthome sold a complete kit.
    FRANK -- winter haven, FL   7/9/2011
    Good product but shipping took too long.
    O Z -- fayetteville, NC   11/16/2010
    Very rugged and versatile. A bit complicated for the novice to install. Requires two power supplies which are not provided with this item.
    JOHN -- polkton, NC   9/23/2009
    works and looks great
    daj -- chicago   7/25/2008
    brought an earlier version of the same model. Has been performing well for a few years - in all types of weather. The wiring diagram does need to be updated however. Not entirely accurate
    BEN -- port neches, TX   4/20/2008
    Not as much as the 1st one I got from yall.
    KENNETH -- willseyville, NY   5/24/2007
    Very Easy to install and configure. Work as advertised.
    AC -- tucson, AZ   11/5/2006
    Excellent Device.. Easy to set up and has yet to give a false alarm.. Only advice is to elaborate on your wiring diagrams (* Not accurate*)
    kevin -- Baltimore   3/28/2006
    Mount them above pet level, and you'll get excellent intrusion detection.
    ROBERT -- silver city, NM   12/5/2005
    Work well to detect deer in the yard and turn on the sprinklers.
