Essential Info

The Safety Technology International 34100 Solar Powered Wireless Driveway Monitor detects when a vehicle enters or leaves your driveway. It uses a solar powered patented magnetometer sensor system which is only triggered by cars and trucks, not people and animals. Movement of any large metallic (iron or steel) object close to the driveway sensor will transmit a signal to the receiver, causing the receiver to chime and flash. The sensor may be placed as far as 1,000 feet (line of sight) away from the receiver in your home. Additional sensors may be required for wide driveways or to monitor an additional driveway.

    Gives 2-3 false chimes daily, usually between 9p-11p, but hasn't missed anyone yet. Sure miss the original model I got several years ago, it was the best!
    Mark -- Upper Michigan   3/9/2013
    Generally works well to announce vehicles, but inexplicably also becomes a low temperature monitor. If the temperature drops to 10°F, it starts repeatedly alarming. Of course this usually happens about 2:30 AM on clear nights, waking up a now barking dog. Unplugging only option to stop. May not be best product for northern latitudes.

    You will need to mount this on a stationary solid post 3 ft tall to make it work. Othewise the wind will make it sound all the time. Directions are confusing at best. Product does work fine if you do these adjustments. Janet IN
    KLEIN PHOTO, -- boulder, CO   6/11/2012
    Wonderfully simple to set up and use, and nice looking product with decent attention to detail. Unfortunately it doesn't work as well as it looks. Having read the directions carefully I placed the sender unit well beyond 25 feet from the nearest road, yet I got at least 10 false alarms a day when cars passed on the road out front. I moved the sender to 45 feet away which isn't near any cars anywhere, and it still falsest at least 3 times a day. I've tried resetting it to "change channels" but no luck. I will be returning the unit in exchange for a more reliable unit.

    This is the second time I purchased this unit. The first worked fairly well for a few years. The only problem was the false signals from large birds and coyotes. This unit has seems to have solved that problem. I now feel confident that it will perform as described, and in fact has been doing so since installation.
