Review: Works Just like I hoped it Would - We have a female cat who unfortunately attracts a lot of Tom Cats. Even though she's been desexed still attracts the toms. And toms like to spray. It smells worse than a public urinal on a hot day. Our cat is only small so often leave my sliding door open just enough for her to come and go and have some where to escape from unwanted attention. Yeh, I spoil her. Not too long ago she attracted the attention of a particularly determined tom. Now I love cats and would never do anything to hurt one no matter what. But in an effort to deter them I use a can of cheap fly spray. The sound is a bit like a cat hissing and the chemical smell is very unpleasant. It worked for years until this particular cat came into our area. No matter what I did even throwing a tennis ball in its direction when I was lucky enough to catch it. I live in a sort of granny flat detached from the main house. The entry is by a sliding door. So at night when I left the door open just enough for our cat to come and go this tom started coming in and spraying. He would spray all around the doorway in and outside. Around the outside of my room and on the walls of the main house. On the water tanks. On the cars. Anyway this tom got quicker and sneakier and short of installing an expensive video surveillance system there was no way I was going to catch it until I setup a Chamberlain motion sensor system. I bought three extra sensors with the main unit giving me four altogether. So far I've only needed to setup three though. Which has given me fair warning when there are cats around and according to how many beeps I know from which direction they are coming from. So now all cats keep their distance and pretty much stay off the property and patrol the perimeter. So for the price I paid for the whole setup it's been an absolute bargain and works better than I expected considering some of the negative reviews I had read prior to buying it. All units take four AA batteries and the main unit has a transformer for using mains power. I live in Australia so had to buy another transformer to suit our power system which is a bit higher than U.S. Only cost $20 more. Still a bargain. As far as setting it up goes it's pretty easy. The instruction manual is very basic. Just a printed and folded sheet of paper. All you have to do is with the motion sensor close to the base station is press the learn button on the base and within 60 seconds press the learn button on the inside of the motion sensor after installing the batteries. And make sure you get them all the right way round or it will make the base station beep every ten seconds or so. Be careful not to nip the antennae when you fasten the cover of the motion sensors. I left all the settings on the two switches in the motion sensors at default. And I thought the volume adjustment was just right for my application. As the Base Unit had battery power as well as mains I could always unplug and keep it in close proximity when needed. As I gained confidence I had the cats under control I didn't have to worry about keeping it with me. As the motion sensors were never more than 10 to 15 meters from the base at any given time never had a problem with distance.
Review: 1,000 feet, -33 degrees F, no line of sight. Works great!!! - Although I just set this unit up today, I just wanted to write up a quick review of a few things I learned or think might be helpful for others that own this unit or and considering purchasing it. So far I am very impressed with this unit. I will update my review after I spend some more time with the unit. As for my setup. I have this unit setup on a remote heavily wooded 40 acres. The air temperature here is currently -33 F. My driveway is 1,300 feet long. I have the PIR sensor (motion sensor) mounted 4 feet high on the trunk of a tree. I have the base unit sitting on my kitchen counter approximately 1,000 feet from the PIR sensor. I do not have the base unit by a window. I have it stuck in the corner on top of my counter. It is too cold out right now to measure the exact distance between the base unit and the PIR sensor, but 1,000 feet is a very good estimate. As I said before the acreage is heavily wooded. The woods are so thick that in the winter with all the leaves off the trees you are still hard pressed to even see 30 feet into the woods. The unit works excellent in these conditions! I was actually very surprised because of the cold temperatures, distance between the base unit and the PIR sensor and the fact that I have nothing even close to line of sight between the two. As for the test. I drove my ATV up and down the driveway three times and every single time it signaled an alert. I used my cell phone to tap into an IP cameras microphone I have in the kitchen by the base unit and could hear the alert tone come from the base. The base never signaled an alert while driving toward the PIR sensor but did signal every time I drove away from the sensor. More on this later. The take away from this. The unit has OUTSTANDING range at my 1,000 foot distance. In cold climates such as mine, use Lithium ion batteries. Normal alkaline batteries (lose power) in cold conditions. Although lithium ion batteries are a little more expensive they are absolutely critical in cold conditions so don't cheap out on this!!! Now finally positioning and understanding of how the PIR sensor (motion sensor) works are also critical. The PIR sensor detects inferred radiation. The best way to explain what that means is to think of the PIR sensor as a sensor that actually doesn't detect motion but detects heat motion. The PIR sensor looks for something in its view that is a different temperature from its surroundings. This gets back to why the PIR sensor did not detect me driving an ATV toward the PIR sensor but detected the ATV every time when I drove away from the PIR sensor. The PIR sensor could not detect any temperature differences between me and the ATV I was driving and the surrounding temperature. The ATV is parked in a unheated garage so the entire ATV is the same temperature as the surroundings.......-33 degrees F. The PIR sensor didn't detect me while driving the ATV either because I was wearing boots, snow pants, jacket, gloves and face mask. All of these coverings were also -33 degrees F. Making my temperature the same as my surroundings. The PIR sensor did however detect me driving the ATV away from the PIR sensor after passing it. This is because the PIR sensor had a clear view of the exhaust and exhaust pipe system which was probably a couple hundred degrees hotter than the surrounding tempature therefore triggering an alert. The biggest mistake I see people making with this unit is positioning the PIR sensor at 90 degree angle to the driveway. Try positioning the PIR sensor to have a view up the driveway to maximize the time the vehicle is in the view of the PIR sensor and it also gives the PIR sensor a good view of the back of the vehicle to detect the heat signatures coming off the exhaust system of the vehicle. I will try to clean up this review up soon. Sorry if it's a little choppy. I am writing it with my three little rug rats running all over the place.

### ⭐⭐⭐⭐ Almost (but not quite) Excellent...
*by E***E on October 20, 2013*

I'm not sure just why I'm bothering to write this,(I usually wouldn't) but in the light of, (in my opinion)a number of unfair reviews, my latent altruism won out. I have had a 'Reporter' alarm (with two sensors)for the past fifteen years. It still operates well, or rather, did until I backed my truck into one of the sensors. I was left with only one that worked, and in my situation, this was not going to be satisfactory. A workable system needs a minimum of two sensors because this allows for a 'sequence' of signals to be signalled at the base station and makes 'false' alarms (caused mainly by animals) easy to recognize. If I hear any one of my three sensors activate I try not to be too concerned but listen-out for the next one. Any animal setting the alarm off is unlikely to set another (different) sensor off as well. A progression of beeps is a sure sign that a human is coming. I have the 'three buzzer' set as the first one in my driveway. This, hopefully stirs me if I'm asleep - and I'm awake enough to hear the next 'two beep' then 'one beep'. It's possible you might wake to a single beep, but you probably won't hear the one that wakes you. So, you just lie there,zombie-like, wondering why you're awake. Then, it's likely you won't hear anything else until it beeps, ten minutes later as they depart with your possessions. This why more than one sensor is a good idea. I have read other reviews, complaining about lack of range etc, but can only say this - the sensors require a bit of 'fiddling' to find the best positions,heights and angles, etc. They do seem to work best, about car wheel/exhaust-height and angled obliquely across a driveway to catch the rear of any approaching vehicle, as it passes. They also need to be as close as possible to the roadway and preferably where a vehicle naturally slows down. Sometimes, when I drive out of my property and the vehicle isn't 'warm' I can get past the sensors without them detecting me. This isn't a big deal, because most intruders will probably turn up, coming the other way, in 'hot' vehicles. Or they'll be walking and spend more time passing the sensor than a car would. And don't worry about 'disguising' the sensors - people just don't seem to notice them, even when I point them out. And although they 'blink' when activated, they blink after the vehicle/person has passed. I know these things are arguable, but I've had great trouble-free service from a set up like this for fifteen years. The only thing I have to do reasonably regularly is clear spiders out of the sensor window - they just seem to like to make it home. My signal (from the new Chamberlain)seems to easily get back to the base from the farthest sensor, a quarter mile away through trees and shrubs. Criticisms regarding the difficulty in replacing batteries aren't really justified, in my opinion. Using good-quality AA batteries the sensor can actually go for years without attention. And there is a 'warning' when batteries are running low. Replacing batteries is easily done, without removing the unit, by unscrewing the four screws on the front panel. Make sure they're tight otherwise water might get into the electronics. One small difficulty I have found is that the clip carrying the batteries can slop around inside the unit. This can cause a bit of head-scratching if the tiny connector that links the batteries with the circuit- board loosens, making the sensor appear dead. This happened to me with one of the units.To overcome the 'slop' I packed a small wad of paper inside the box to prevent any movement of this battery pack. I have seen other contributors be very critical about the lack of volume coming from the base as it 'beeps'. To me, this is not the problem. At night, when you really want to hear it whenever it sounds, it is audible enough - the problem is more the fact that the beep isn't 'distinctive' enough. The beep sounds like a large number of other beeps made by various appliances around the house- dishwasher, washing machine, microwave, etc. If you are relying on picking-up just a single beep it could be very difficult to differentiate from other very similar ones. The old 'Reporter' was only a little louder than the Chamberlain but it had what could be called a 'unique buzz' -it was distinctive and noticeable and if it was any louder might've almost been annoying. So, all in all, I think that this unit is good value for the money but would be so much better if it sounded-off with a 'buzz' like the old model, rather than a 'chirp'. The only real criticism I'd make is that the product description does not make it at all clear that there is one sensor as part of the package, along with the base unit. Calling the System 'black' and then showing only the base as black (and the sensor beige)adds to the confusion. (Or did I miss something somewhere?) The other thing not made clear is that there is a 'transformer' unit with the package, allowing the base to run from a power outlet. Is this sometimes not included because I notice some customers complaining about how quickly it empties batteries? The batteries, I thought were just for emergency backup and personally I wouldn't worry about batteries in the base unit, unless that was the only option. ps. Great service too. I received the parcel in New Zealand (by the cheapest ordinary freight)five days after I ordered it. Well, done Amazon.
