Not a stand alone device. Receiver only works with Hosmart Solar Sensor
I really like that Hosmart is offering a sensor with the Solar charging feature so I don't have to be concerned with manually recharging the batteries. Fortunately, they also retained the "USB charging port" should the weather not provide enough ambient light to activate solar charge feature (extended periods of dense fog, heavy snow, etc.). The battery pack they are using is Li-Ion which has some integrated circuitry that probably is a charge controller function so the batteries receive proper charge & do not over charge. I think of it as a "smart battery pack". Battery pack It is very well packaged in foil/cellophane which should protect it from any condensation, etc.
I have "temporarily located" this sensor in full sunshine area on top of a well-head on an embankment overlooking our driveway. If that location proves to be ideal I will remove the rear mounting plate and use industrial Velcro on bottom to attach it on well-head cap. If not, I might paint the sensor black (after masking off the solar panel, eye and USB plug) and locate it on my black gate post at driveway entrance so it blends in with gate (stealth). The distances I have tested it at are 300' and 700' and it trips the receiver alarm reliably. Tip: If you don't want the red led light to display when triggered you can use channel 3 or 4 which are stealth modes (no light emitted through eye).
I don't normally write reviews but after this morning I had to write one for this driveway alarm. I was woken up at 5:50 this morning by my driveway alarm going off. I almost didn't get up thinking it was a squirrel since they set if off occasionally. Thankfully I woke up, looked out the window and saw the interior light on in my vehicle. Long story short, my vehicles were broken into and the thief had entered my yard from the neighbors yard but exited through my driveway setting off the driveway alarm and waking me up. Thankfully, he was caught shortly after exiting my driveway, but not before making his way a mile down my street and breaking into numerous vehicles. If it wasn't for this driveway alarm, my house wouldn't have been the last one he hit and he probably would have gotten away with it. Needless to say, my neighbors are all asking for the link for this item so they can order one as well.
The driveway motion detector worked really well. The problem with it is that if a neighbor has the same unit you will get each others alarms. I sent Hosmart a message about this issue and they sent me a different model. That corrected the problem as long as another neighbor does not buy the same model as mine. I would think that one could be developed that would use different frequencies. Hosmart was very quick and helpful in helping me solve this issue.
This company is the best , I had trouble with the one I bought and they had their guy call me about it . I had a new one in less then a week . This works so good we had to set the sensitivity down the rain drops coming off dish was setting it off .
Used this product as an automatic door alert. My home has a metal roof and other models were very problematic on wireless signals being received at base station. This unit was easy to install and has the added feature of solar charging. Chime is a pleasant tone and easily recognized among the other tones in the home and is heard throughout the home and can be turned down for conversation. Excellent for use in an RV or Camper where security of the area is required.
