ORIGINAL REVIEW
They sell these locally at Harbor Freight stores, so if you live near one just drop in, they are $17.99 plus tax. I was having problems with my wireless doorbells working reliably so it occurred to me that one of these would cover both my front doors plus let me know when the mailman or UPS had been by. Also, from a security standpoint, hearing an alert when anyone was on the property approaching my front door was a big plus. For $20 I honestly didn't expect much.
The sensor and receiver are nothing fancy but SURPRISEthey work perfectly! In fact, the sensor was TOO sensitive and was picking up cars going by in the street (about 20-25 feet away). I had to change the sensor position to facing across the property in front of the house instead of facing the street. So far it works flawlessly. It was been out in the bitter New England cold about a week. Give yourself a day or so to test it out before permanently fastening it in one location. That way you can be sure it is adequately covering the area you want it to without a lot of false alarms.
I secured it to a railing on the front steps with two plastic locking cable ties. If you are worried about someone removing it, use a metal clamp from the plumbing section in Home Depot. It comes with two screws and a hole on the back of the sensor to mount it on a wall-that didn't look very secure to me at all and it would be too easily removed. There is a small flashing red light on the front of the sensor that gos off when it "sees" you. If you like, cover it with tape to make it less visible especially at night). I bet you could hide one of these in a bird house or something like that if you really wanted to conceal it. It didn't try this though as its not necessary for me.
The receiver is pretty loud on the high setting and can be heard through the house. It has a low and off setting too so you or whoever's in the house don't go insane if you are using a monitored area a lot for the day. (Just ask my teenager who was "trying to sleep" during my installation and testing phase on Saturday morning).
I realize this unit is still new and has not been through any major rain or snow yet. I will return in a few months to update this review. I was happy enough to buy a second one to put on the back deck that has a glass sliding door. I read there is a way to get two sensors to sound on one receiver but I figure if I leave one set on high volume and the other on low volume, I will know which one is actually sensing something. I hope this helps you decide. Don't let the low price fool you, this thing really works!

I just wanted to post a review/comment because I see people making reviews and comments that are rediculous. These units are an excellent low cost security motion sensor unit.I use these in the mountains and most are there 6 months out of the year and they endure all the weather the mountains can throw at them. To this day I have never had one gliche yet and some of mine are over 3 years old. Battery life with them is also excellent.
You need to pay attention to the product information, the motion sensor is NOT water proof, they are weather resistant. that means DONT put them where they will get soaked or filled with rain or water....DUH...
Also, people mention that it will continue to chime or alarm, the sensor has a wide angle fresnal lense, that means it will pick up motion in a very wide area horozontally and vertically. Also, they are heat sensitive, so if it is in direct sun light or where it will see moving shadows from the sun it will trigger the motion sensor. It will trigger from motion and heat, a small tree branch moving to a butterfly flying across in front of the sensor can and will trigger it.
Here is a tip, you can cut down the amount of area the motion sensor picks up by just putting a couple small strips of masking tape vertically along the edges of the motion sensor fresnal lense, you can also do this across the top and bottom of the lense to narrow the detection field vertically. Simple thinking and it works like a charm.
To water proof a sensor, use some silicone around the outside of the sensor casing along the seam, then put a small bead of silicone around the outside edge of the fresnal lense. this will help protect it even more from wet weather. The best way to protect it is to place it under an eave or under some sort of cover so it doesnt get soaked. very simple.
These units also come in different channels, so you can get many units using the same frequency. Place one chime/reciever where you want to hear it and then place as many of the sensors outdoors as you want, you will have extra chimes/receivers but who cares, for the price you cant beat these units.
For the record, I would not buy any other type, these have served me well over the years and I will continue to use them as long as they continue to make them. An excellent product and I recommend them to anyone that is on a budget for security or would just like a low cost peice of mind for around there home or business.
Ya gotta be smarter than the box they come in.This driveway alert works great. Has already worked for us when a person was trying to sneak up our drive way to check out our vehicles with robbery in mind. Worth every penny.I purchased this unit about a month ago. For the first couple of days, the unit worked fine, and then it rained. The unit filled with water and stopped working. I took the battery out and let the unit dry for a few days, and it did work again, briefly. It stopped working again, and after checking, moisture again....would not recommend for outdoor use unless you have the unit encased in something to protect it from the elements.
