AI-generated from the text of customer reviews

799 customers mention652 positive147 negative

Customers like the quality of the surveillance systems. They say it works well, has amazing range, and has very few false alarms. The first sensor worked great with no issues, and the new sensor has worked well for a few months. The system works reliably in hot, cold, wet, and dry conditions, and can be used for any number of applications. It works from a long range and can operate at 52 degrees.

"...The mounting plate worked well, I pre-assembled everything and just screwed the mounting plates directly to trees near the driveway using deck..." Read more

"...Update: 3.5.13 - System still working well. The units have endured many storms and direct rainfall and still function properly...." Read more

"...After being in operation over two years, the sensors are working just fine. I'm truly amazed and highly satisfied...." Read more

144 customers mention114 positive30 negative

Customers like the value of the surveillance system. They say it's inexpensive to operate, well-built, and offers very effective coverage. Customers also mention that the sensors are very inexpensive but offer very good coverage. They find it worth it to use lithium batteries in these, as they last twice as long.

"...Awesome value!..." Read more

"...that does what it claims, is affordable and expandable, is inexpensive to operate, and is well-built and withstands the tests of time, then look no..." Read more

"This product does exactly what I was looking for, and at a reasonable price...." Read more

"...NONE are sealed around the lens - no gaskets, no oring, no nothing. The lens just snaps in loosely...." Read more

128 customers mention119 positive9 negative

Customers find the installation of the surveillance systems to be easy. They mention that the units are easy to setup, connect to the base unit, and assemble the sensors. Customers also say that the system is simple and reliable, and pairs easily with the base.

"...No false alarms and no missed trips yet! Super easy to install to tree...." Read more

"...I ordered the base/sensor package and an extra sensor. The setup was extremely easy...." Read more

"Super easy set up and it works better than expected. We have one set up at the front of the driveway and a second on the back deck stairs...." Read more

"Easy to install? Sure. All you need is a brain and a Phillips screwdriver.Motion detection? Great...." Read more

111 customers mention91 positive20 negative

Customers like the range of the surveillance system. They say it has a long range, and has good coverage to the receiver. Some customers say they have never had any problems with distance or triggering of movement. They also say the system transmits perfectly through a heavily wooded area and through several walls. Overall, customers are satisfied with the range and functionality of the product.

"...Reception so far is good...." Read more

"...Signal is tripped by deer, people, and vehicles. No false alarms and no missed trips yet! Super easy to install to tree...." Read more

"...The range is very good on these...my driveway (sensor 1 of 8) s about 125 feet from the receiver and has no problems...." Read more

"...The Good: - Cheap - Good Range - Durable - Good sensitivity..." Read more

139 customers mention79 positive60 negative

Customers are mixed about the alarm. Some mention it has amazing distance and very few false alarms while still accurately detecting critters in the yard. They also appreciate the different number of beeps for each sensor so they know which one is real. However, some customers have reported that the alarm constantly alarms and drains the battery.

"...The beep is loud enough (at high volume) to be heard throughout the house, even on other floors...." Read more

"...It seemed to work well - for awhile. Then it started falseing almost continuously with short periods of silence...." Read more

"...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

110 customers mention38 positive72 negative

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

80 customers mention48 positive32 negative

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

68 customers mention36 positive32 negative

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

Really good, but not quite great without some work.
4 Stars
Really good, but not quite great without some work.
Easy to install? Sure. All you need is a brain and a Phillips screwdriver.Motion detection? Great. Especially if you make use of the integrated distance and sensitivity DIP switches.Distance? Awesome. Unless you need something “extreme,” then yes. These WILL reach.Weatherproof? Ouch. If you mount them at least 1.5’ off the ground and live in an area with zero insects, you’re golden.If you mount them UNDER 1.5’ from the ground and/or have insects where you live, buy a cheap tube of RTV simultaneously.I had rain/humidity corrode batteries in the carrier, and ants creep in the sensor face.Solution? Exactly what the manufacturer could have (read: SHOULD have) done originally. Fill the channel in the face of the sensor plate with RTV sealant/gasket maker. Allow to dry, THEN assemble and deploy.Result: 95% more weatherproof than original. As far as insects, I find a few pellets of ant bait in the assembly is worth its weight in gold. (Otherwise your sensor may go off intermittently AND perpetually. Insects seem to be drawn to the IR/whatever wavelengths.)A cheap can of flat black spray paint may also be valuable; up to you. Just a word to the wise. 🤗
