  • More Info

    Precision-molded curved lens
    Unlike other thin flat lenses, the NightGUARDIAN lens is molded into a curve, so it is distortion free and water-tight. No false triggering either due to distortion or moisture problems. In fact, the entire NightGuardian unit carries a UL rain-tight rating. Unlike the competition, it does not have to be placed under an eave or in a protected area.

    Advanced surface-mount circuit board for greater reliability and longer life
    Similar to the circuit board circuitry used in personal computers, NightGuardian technology provides reliable, accurate performance from -40°F to 120°F. This means no false triggering due to wind, leaves and swaying branches, snow, rain and hail, barometric pressure changes or sudden temperature changes. The competition often uses 30 year-old technology, using push-through mounting of components onto the circuit board and a layer of solder to make connections between circuits. This type of circuit responds slowly and has to go through many connection points, providing many potential points of failure.

    Built-in surge protection with auto-reset
    Unlike the competition, the NightGUARDIAN resets itself instantly after power surges, outages and shortages. Additionally, if the competitions' product is miswired during installation, the circuitry is generally destroyed. With the NightGUARDIAN, the unit simply resets itself once the wiring connections are corrected.

    No mounting height limitation
    Only NightGUARDIAN can be installed at any height, even above 12 feet. With its UL rain-tight rating, NightGUARDIAN can be placed in open weather... it does not require a protected area.

    Flexible detection coverage
    NightGUARDIAN offers "Sneak-By Guard," which prevents intruders from sneaking under the lens. Minimum coverage distance of 40 feet, even farther in colder temperatures. Views a 140° horizontal angle that adjusts to cover any 140° in a 270° sweep, with a 65° vertical plane adjustment. Zone adjustments made easy with clip-on shrouds that allow split zones. Timing adjustable from 10 seconds to 15 minutes.

    Microprocessor manual override
    The competition's product will often slip into override as a result of power outages or surges, wasting electricity until you notice the unit is in override mode. With the NightGUARDIAN, the unit will automatically return to normal operation after four hours. Additionally, a red indicator light behind the lens lets you know the unit is in manual override mode, eliminating guesswork.

    I have purchased and installed my share of home improvement store motion lights they are usually of questionable quality. The Night Guardian is superior in every way and I am very satisfied with my purchase.
    FRANK -- hampstead, MD   10/15/2012
    Very well made product at a great price. Rapid delivery - well packed.
    LISA A -- fallbrook, CA   9/12/2012
    puts out good light to cover driveway but not over and beyond to the neighbors across street. Nice and bright where the area called for needs to be . . some tweaking for the motion sensor's sensitivity levels but that is expected .. .
    GARY -- kihei, HI   9/1/2011
    Does not have the range of motion I was hoping for. I needed to put in some wedges to get it aimed where I wanted it. Also it would be nice if wind in the branches did not trip the sensor. A motion sensativity control might help on this. Overall a really quality product.
    JAMES -- prescott, AZ   12/5/2008
    Great product and service.
    HAROLD -- morganza, LA   5/17/2006

    CANDACE -- everett, WA   8/6/2005
    The electricians were very impressed and even enthusiastic about the lamp, which I respect since they install a lot of these kinds of lights.
