This alert system is compact and very effective. The one that I am replacing lasted for approx. 6 years. I've come to heavily depend on this particular driveway alert system. By experience I learned early on that you have to shelter the outdoor part of this unit as rain/snow can wipe it out pretty quickly. Because I wanted secrecy, I covered the little 'red' light on the outside part so that intruders were unaware that I was monitoring for trespassers; consequently no one comes near my cabin without me knowing it. Unfortunately, they also alert when animals pass by them. This system has a volume control switch (high/low) so that's a good thing. Bunker Hill is a good brand, but I would suggest that customers buy the better batteries for them as they last way longer - meaning that you don't have to make as many trips outdoors to replace them. With good batteries I can usually go about a year without changing them out. Highly recommend this product. Read full review

If you walk in front of it 5 times it might only activate once or twice. There were many false alarms for no reason. My porch is closed in and locked at night, yet it would activate and would not shut off until I removed the battery. This always seemed to occur when the weather turned colder. I have others units from a different company that work great, so I know how to properly use them.

Great little device, I have been using Bunker Hill wireless alert system for 4 years now, and for the price, that's an unbeatable deal. The battery last for over a year and the outdoor sensors works on all weather conditions. I am very pleased and I have recommend it to many of my friends.

I own a small business and every time I would walk to the back, someone would always come in the front. I never knew they were there until I would see them leaving or here them yelling for service. The door chime works great. No more surprises. Steve W.

Armadillo constantly forage in our yard here in Florida. They are so strong that they break out of the live trap I set and damage the door so I use this to tell me as soon as one enters. Works great, although wife doesn't appreciate the nighttime alarm, and no more damage to the trap or lawn.

This is the best security product on the market. Buy a couple before the prices soar when everyone finds out how great it is. I have a wide driveway, somewhat hidden from indoors so having the indoor 'bing-bong' sound is fantastic as it alerts me to someone driving or walking up to my home. No cameras needed! Super simple to install- small and no one can reach it- I purchased 2 more for each side of my yard (back to front), and a 4th for across the back yard. Easily turned off and on, battery lasts a very long time, I am 100% secure on 4 sides for about $80. I have given 3 of these as house-warming gifts- it my all time favorite and most useful item for any homeowner or renter. No need for the new "doorbell"- no need to speak to strangers! They are always well received! Bunker Hill is the brand- Perfection! I have not tried the others. My first one is working day and night very well at the age of 8 years or so! I heartily recommend!Read full review

This Bunker Hill system works flawlessly . Second one purchased over a three year period for a friend. Accurate as long as the motion detector is out of direct bright sunlight and no insects or wall climbing lizards,passing cars and people and such are not false activating the sensor. A lot of alert for little money.

First leave me respond to the guy who says they are junk and sound on there own. Birds and squarles set mine off all the time. I have 1 at my front door, I have 1 at both my gates going into my back yard and I have 1 on my back yard fence covering my entire yard and I have 1 in the peak of my roof covering my two cars in the driveway. I love these things. My property is totally covered. I also hooked up my daughters house with these and they love them. This is an inexpensive way to protect your home or property. One word of advice, use good batteries. If you use cheap harbor freight batteries they will leak in the battery compartment and it seeps out of the cover onto what ever you have them setting on.

This is not an alarm system but it does let me know when someone drives into my drive way and walks onto my porch. I like that if I look out and don't know who it is, they can hear the alarm chiming as they move around my porch. I never open the door to anyone I don't know.

when it works, it's fine. About 50% of the time it fails to alarm. If a white vehicle passes on the street on a sunny day, it alarms. worst of all, two - three times a day it goes crazy and won't stop alarming. I turn it off for about five minutes and it will go back to working right. TOTALLY UNDEPENDABLE!
