"...As with the 1st sensor, I have experienced no false alarms or missed trips. Great, reliable, affordable security system...." Read more
"...and do not get much driveway traffic, but the darn thing kept going off with false alerts and that ran the batteries down...." Read more
Customers are mixed about the battery life of the surveillance system. Some mention that the batteries have lasted several months, much longer than expected. They say the system is easy to install and operate, and runs on batteries. However, other customers say that the last one only lasted a few weeks, the battery begins to fail in any sensor, and the system died in less than 3 months.
"...- Low Battery Warning Is USELESS. When a battery gets low on one of the sensors you get a small bep from the monitor every few minutes...." Read more
"...Those batteries withstand much colder temperatures, last well over a year, and are the only way to go...." Read more
"...the unit on the nearest distance and least sensitive, but it still kept going off when no one was coming up the drive...." Read more
"...Otherwise your sensor may go off intermittently AND perpetually. Insects seem to be drawn to the IR/whatever wavelengths.)..." Read more
Customers are mixed about the sensor. Some mention that the unit is sensitive enough to alert when other boats or persons go near the pier. However, others say that the sensors are not perfect, work most often, and go wild when it detects someone. The system with the caveat that failures of the sensors can be problematic.
"...So far this has a 100% accuracy rate...." Read more
"...and sender unit as a package, but in less than a year, the sensor unit crapped out...." Read more
"...The unit is so sensitive, it was picking up the movement of the grasses in the breeze...." Read more
"...The Good: - Cheap - Good Range - Durable - Good sensitivity..." Read more
Customers have mixed opinions about the motion detection of the surveillance system. Some mention that it works great and picks up movement well, while others say that it's erratic and fails to detect motion at distances over 3 feet. Some customers also say that the sensor senses some types of movement much more strongly than others, and seems to miss slow moving objects. However, sometimes it picks movement 50 yards away.
"...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..." Read more
"...limitations of the outside sensors is that it senses some types of movement much more strongly than others...." Read more
"...I have one at entrance, and one 200 ft from house. They always pick up vehicles unless vehicle is speeding...." Read more
"...The old model sensor did OK but missed several door movements...." Read more

There was a problem filtering reviews right now. Please try again later.
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.
Update: 11.10.12 - Recieved 2nd sensor. Put in batteries (4 AA). Press learn button on base unit, wait for the beep, press learn button on sensor and wait for beep. Screw on plate cover and you're done. No adjustment on the 1st sensor needed. Now my first sensor is located 600' up the driveway, and the second sensor is located 300' up the driveway. 1st sensor beeps twice when tripped, 2nd sensor beeps three times when tripped. Perfect early warning system. Deer trip my first sensor when crossong my driveway but because they do not walk down the driveway they do not trip the 2nd sensor. Now I know when someone is walking or driving down my driveway. As with the 1st sensor, I have experienced no false alarms or missed trips. Great, reliable, affordable security system.
Update: 3.5.13 - System still working well. The units have endured many storms and direct rainfall and still function properly. The freezing cold temperatures seem to have no effect on these little gems. I keep meaning to get out there and install a little plywood roof over each device but haven't done it yet. Just ordered 2 more sensors for a total of 4 so far. Like others I have noticed that a fast-moving object may not trip the sensor. 1 tip, install a 'Private Property' or 'No Trespassing' or 'Slow - Children Playing' sign near each sensor, this makes visitors slow down a little and ensures sensors will activate. Still very pleased with this low-cost security system.
