There was a problem filtering reviews right now. Please try again later.
One thing that really stands out with this system versus other PIR models is that the sensor was specifically designed as a driveway alarm sensor. All the others take a standard indoor security sensor and modify it to be a driveway alarm. This makes a big difference in false alarms. I haven't had any with mine. Following the installation instructions closely is key here.
Another useful feature is that on battery backup you can carry the receiver with you while you walk or drive around. This allows you to test the system as you make adjustments or try different detection scenarios.
Things you might not like:
It needs 8 AA alkaline batteries (4 are optional for receiver backup). But they should last a long time.
The alert sound is a coarse sounding double beep. You quickly get used to it.
The volume is adequate for me. But I'm surprised it wasn't designed with more available volume. This seems to be the main complaint in reviews.
The power LED on the receiver stays on when the receiver is on battery backup, wasting battery life. This is just dumb.
Notes:
If you are in a very cold climate you might upgrade to lithium batteries, at least in the sensor.
If you have a large home you can buy unlimited extra receivers and place them in remote locations.
Up to 8 sensors can be paired with one receiver.
PIR Systems in general:
Keep in mind that PIR (passive infrared) sensors like this one will detect all moving objects, including people and animals. I actually like the fact that it detects people walking up my driveway, so this is a plus for me.
If this is a problem for you and you need to detect only large metallic objects such as vehicles, you should go with a magnetic system instead. I have tried these and have had poor luck with them. They are unstable and detection is inconsistent. It is difficult to get satisfactory performance from them. Also I find they don't have enough detection range. If there is rebar in your driveway this could interfere with the detector. There are other types of systems available also such as rubber hose and break beam types. They are more expensive and installation is more involved.
Summary:
In summary I am very pleased with this product and would recommend it to anyone.
UPDATE: I have had this now for 6 months and couldn't be happier with it. It is very stable and reliable.
The reviews that talk about heat and partial detection are correct, placement and aiming is really important. I installed these at the end of a driveway that runs east-west in an open field, so road traffic and the sun were factors. I placed two units, one each on opposite sides of the driveway, facing towards the driveway at about a 45 degree angle away from the road. Each unit was secured to a tree about 18" off the ground. I placed two opposing units because for one, I was concerned about reliability based on some reviews, and two, on cold days it does need to see something hot so I wanted to capture exhaust heat regardless of where it was placed on the vehicle.
Each sensor is placed approximately 12-15 feet from the driveway, which is about 12' wide itself. This seemed to be the perfect placement; movement anywhere on the driveway activates both sensors; if you get a few fee off the driveway it only activates the nearest sensor.
So far this has a 100% accuracy rate. I haven't had any confirmed false alarms; out of the handful of non-vehicle alerts we've had, a few were confirmed to be deer or dogs and others just couldn't be confirmed in the darkness. It does pick up humans; it had no problem detecting me walking down the driveway on hot days nor when I was thoroughly bundled up from head to toe on cold days. I've had no issues with the sun nor passing road traffic interfering with the sensors.
The sensors have a green LED that activates and is visible through the PIR lens for about 1 second when they detect motion. It's usually not a big deal, but on a dark night while driving towards the sensors the green light stands out and quickly draws attention to the unit. If you're going for a covert installation, keep this in mind.
A previous homeowner had one of these units installed very near where I installed my new units. It showed signs of corrosion, and based on other reviews I agree that water intrusion seems to be an issue. So, when I assembled my units (yes, some basic assembly is required but its not rocket science), I used clear silicone to make a good seal around the face plate, including the antenna hole and screw holes. I installed the included sun/rain shade above the units too. When I change the batteries next time I'll see how they're doing at keeping weather and bugs out. I wish I'd had some Lithium AA batteries to use when I assembled these; instead I had only alkaline batteries on hand. I'll hopefully provide an update here on how long the batteries lasted and how well they're keeping dry.
The mounting plate worked well, I pre-assembled everything and just screwed the mounting plates directly to trees near the driveway using deck screws.
Reception so far is good. These 2 units are placed right at 100 yards from the residence, across an open field with no obstructions aside from a few small ornamental trees. The signal then has to pass through concrete siding and 4 interior gypsum walls. The beep is loud enough (at high volume) to be heard throughout the house, even on other floors. Pairing the units with the receiver was easy enough.
Things I wish were different on these:
The beep when a sensor activates is a long sort of whiny squeal versus a quick chirp, and its a little irritating. Not necessarily bad for an alert, but it happens to closely mimic the washer and dryer beeps. Each sensor that is paired with the receiver gets a corresponding number of beeps. With 8 units, that's an awfully long series of irritating beeps.It would be great if the alert beeps could be adjusted (pitch of tone and length of the beep).
It would be good if there was an aux output (dry relay contact) built in to the unit so this could be tied to a variety of other systems. Even better would be 8 discreet relay contacts (one for each sensor). Best would be throwing in a Z-Wave or similar smart module so you could really integrate this with other systems.
With a simple sequential beep for the sensor zone number (1 beep for zone 1, 2 beeps for zone 2, etc), you run into some problems. For example, if sensors 1 and 2 activate at nearly the same time, you get 3 beeps. Well, was that sensors 1 $ 2 going off, or sensor 3? Did sensor 4 activate or was that sensor 2 twice? You get the idea. If the sensors had a unique beep pattern (for example, a high pitched tone followed by a number of low pitch tones for each sensor) it would be easier to distinguish the different sensors. In this case 'hi-low-hi-low-low' would easily be distinguishable as sensors 1&2 versus the 'hi-low-low-low' of sensor #3. The point is, the current system can be confusing across zones and there are many answers to this problem, but the manufacturer should pick one and implement it.

01/08/2013 for a full refund including postage but this has not yet been received.
Seems to consistently work well.
Only complaint is that the tone only sounds once on each activation and is not as loud as it could be.
If the volume was turned up more and /or had a different sound other that just a beep, it would be better for our purposes.
A chime like a door bell, or longer sound would be a lot better for us that may be a little hard of hearing.
