    After having some security issues that mandated motion sensors I bought three of these units to replace another popular/competitive sensor that failed to achieve it's advertised potential. These Optex sensors are great. They have a good, usable distance, especially if set on the beam setting, and don't produce a lot of false alarms. They will pick up birds or small game if placed in an area of activity or on the ground but set at 12-24 inches above the ground they work great. The beam will catch anything out to about 60 feet and the fan setting is good to about 18 feet. So far all good.

    Replacement for a transmitter bought years ago and damaged by squirrels.

    Easy to set up. Linked with both of my existing receivers. Requires batteries about twice per year - otherwise no adjustments or maintenance necessary.

    The earlier model did not work well in the rain. This one seems to work fine in all weather.

    Overall an excellent product.
