Question: Does this work better if placed where car doesn't run between sensor and receceiver? or does it matter if car passes between sensor and receiver?
Document: Nice concept but quality contol problems mean you should keep looking for a better solution. The sensor was missing a stake. I contacted the company for a stake and they told me I had to work it out with amazon. Amazon gladly replaced the whole sensor. I got the Lamp controller and while it would turn on the lamp, the timer function did not work. Amazon replaced the lamp control with one that works. I bought a second sensors for my 650 ft driveway.
This driveway monitor did not work well on my properly with steep slopes on either side of the driveway. It probably does much better on a flatter surface.
One sensor will miss a car while the other sensor will catch it. I added a motion sensor to catch the cars the sensor misses which defeats the purpose of using this sensor.
Safety Technology International STI-34150 Battery Powered Wireless Driveway MonitorI have had the unit now for 8 or 9 months and have given up on getting this thing to work properly. My original intention was to mount the transimitter some 800 feet from the driveway to the receiver in my house but could not even get it to sync up at 250 line of sight feet. (not the 1000 feet that's advertised).
I had high hopes that this model would work as well as the one I had owned previously which has been discontinued. I have had it only 6 months and have returned the receiver for replacement and it still does not work. It will intermittantly make weird sounds but none purposely. I feel this was a gross waste of money and would not recommend it to anyone. I am back in the market to find a Driveway alarm that will work. Any suggestions !! !
I first purchased STI's earlier version of this item. It did not work very well at all maybe 20% of the time. I tried working with it to give it the benifit of the doubt, but no luck in improvement.I worked with the STI email technical support and they spent a lot of time communicating with me to reprogram, etc. No luck. I finally told STI that I wanted a new unit. They sent a new receiver only and that did not resolve the problems.
We needed a driveway alert for the house to advise us of visitors. Tried the "motion detector" type using passive infrared technology, only to have wandering night time animals, wind, leaves, etc., constantly set it off. The STI sensor is a "magnetic field disturbance" type of device. A car, motorcycle,  bicycle, or something with a sufficient metal mass is needed to signal an alert. (I did drive my wife nuts one day using a wheelbarrow by it).
I bought the sti-34104 battery operated wireless alert system in April worked great for about six days, the started going off every few minutes for no reason. I had to clear receiver memory and reactivate, worked okay for another five or six days and I had to repeat same procedure every five or six days. I called tech. support and they had me do the same thing. I had to do this three times and it still would only work five or six days.
Did not work as advertised. Had to place sensor so close to house that it defeated the purpose of buying it (I have a 250 ft. driveway). Then the in-house alarm would trigger and continue for no reason whatsoever despite resetting. Waste of money and time.
So far they are working great. My sensor is 300 feet from the receiver. Don't know about durability, only had them for a few months.
