Bunker Hill Wireless Security Driveway Alert System

My father in law has dementia, so it's used to alarm us when he gets up and wonders in the middle of the night

I like the signal distance as the motion sensor is installed at the front of the house and I have the alarm inside in the back of the house.

I would highly recommend as this works very well, but ours stopped working after two years because bugs got in it outside.

I put the 3 batteries into the receiver, it gave me a signal as described in the manual.I put a new 9v battery into the sensor. No action at all, dead. No alarm or LED indication. Useless.Update: I selected to have a duplicate product sent instead of a refund. The 2nd unit works fine.I placed the transmitter in my boat at the dock, 225 feet from the receiver in my house. The signal passes through the fiberglass hull and through 2 walls in the house. It senses and alarms when anyone in the boat moves.

I bought this unit on October 11, 2012 from Homesafe. I mounted it outside, under the roof of a carport and facing my driveway. The range seems to be only about 30 feet, which is far less than what was advertised but works great for me because it didn't respond to traffic on my street beyond the end of my driveway. That kept false alarms to a minimum; they only occurred a few times over a 7-month period (using the alarm perhaps 10 hours per week on average) when deer or ground squirrels walked within range of the sensor.The alarm on the receiver is plenty loud when set to the High setting (I can actually hear it sound when I'm on a different floor in my two-story house). The 9-volt battery for the outdoor unit (the transmitter and motion sensor) lasted for four months before it needed replacing, great performance considering this spanned the autumn and winter months in Central Oregon (where it regularly gets down to the teens and twenties and can get down to below zero on occasion during the winter). This leads me to conclude that the system is very efficient in its power usage.Unfortunately, the system stopped working a few days ago. I replaced the three C batteries for the receiver and the 9-volt battery for the motion sensor/transmitter, but the alarm still doesn't sound when I walk directly in front of the sensor. The LED for the motion sensor still lights when it detects motion, and the alarm still sounds when I turn the receiver on, so the sensor and speaker are evidently still good. I suspect the receiver's chip has died.Aside from the premature failure, this is a good unit that I would recommend to anyone who needs a driveway alarm with very limited sensor range. Other reviewers have noted better range, so manufacturing tolerances are evidently at work here, and your mileage may vary.Postscript: I ordered a replacement system by the same name ("Driveway Alert System") from True Power. What I received was slightly different from what I"d received before (same form factor, but different switch configuration), perhaps an updated version. It worked intermittently for 24 hours, after which time it consistently failed to work: The sensor's LED would light when a person or car crossed its beam path from only several feet away, but the alarm wouldn't sound even with the receiver only 40 feet away with a clear line of sight (no walls or windows obstructing the signal path) and no RF-producing equipment within at least 30 feet. To their credit, True Power sent a replacement without requiring me to return the defective unit.Postscript: The replacement system failed also. It worked twice, then consistently failed to trigger thereafter. I replaced batteries in both units, but that didn't help. Both sets of batteries for both sets of units -- transmitter and receiver -- were fresh/new EverReady Gold batteries with expiration dates in 2018. So I can categorically rule out that spent batteries are the problem. Also, once the system failed (after two successful alarms), it would not trigger no matter how close together I had the transmitter and receiver. Whether placed indoors or outdoors (far away from the house and from any potential RF; there is no above-ground telephone or electrical wiring on streets in my development), the two units would not trigger even when they were literally less than one foot away from each other and when walking directly in front of the sensor from less than two feet away (in all cases, the sensor's red LED would light, but the receiver wouldn't respond).Postscript 7/17/13: True Power refunded my money, including shipping, for the defective units. They maintained they could not get the returned units to fail in operation, so the units' failure on my end is a mystery (especially because I've since bought a different brand/model of driveway alarm, and it has consistently worked reliably from the start). True Power's customer service and communication were excellent. I would do business with them again.

I’ve had one before and I know I loved the way it workedGreat product and not a bad price either!

Product works well.

I purchased two of these in Jan. 2020 around 2 weeks apart. The first one was identical to the security alarm I bought through Publisher's Clearing House around 1.5 years ago. The sensor even triggered the same receiver. There are three chimes each time the sensor is triggered, and the light on the receiver stays on all the time. I returned the first unit from Amazon because one of the bolt holes for the battery cover on the sensor was stripped from the factory, because the hole is just plastic and the screw is self-tapping.The second unit I received from Amazon two weeks later is quite different and probably the 'new' model. The sensor no longer triggered my old receiver. In addition, the light on the receiver turns off and does not stay on all the time. One thing I don't like is there is only two chimes each time the sensor is triggered (I prefer three like on the old unit). But I see two improvements on the sensor: they beefed up the 9-volt battery clip as the old one was flimsy and easy to tear. Moreover, they use steel inserts for the screws on the battery cover, so there is no fear of stripping the soft plastic on the housing. It also seems the HI chime is a lot louder than the old unit (too loud actually).Anyway this sums up the confusion some people due to discrepancies on how their units behave. Here are some improvements I would like to see if the manufacturer is reading this:1. Would like a large, blinking sensor light when it is triggered. This is more visible should a burglar notice it when casing your property. The current light is too small and it is hard to see it blink when triggered. If the burglar thinks they have triggered the sensor, you can bet he will leave the property pronto!2. Again, go back to three chimes rather than two, when the sensor is triggered.Update: This product I purchased in Jan. 2020 already failed 3 months later. It's a piece of junk!

Arrived earlier than we expected and it works perfectly!

We bought this Bunker Hill alarm on Mar 22/ 2022. It worked for approximately 3 weeks, now although the batteries were and are new, and each seprate unit is working., they won’t communicate to each other. Very disappointed in this product.

ordered two, one finally worked after some fiddling, the other did not work so it is being returned. Asked for a replacement and the company said they don't have a replacement but I can reorder ?!

Works well.

the product itself works as indicated.It provides for an ac hookup but does not provide the cord. I was concerned that my card was charged in advance of shipment (which they said would not happen). From time of the charge to my card to actual receipt of package was three weeks. Not what we expected. First timer to amazon shopping and was led to expect a bit faster turn around. No invoice was provided with product. Would like to have one for my records.
