I installed this on back of property to detect any intruders trying to gain access, detection works flawlessly. Batteries have maintained a charge even with many days of overcast. I Highly recommend them.

Purchased this product to try it out and to recommend it to other customers because I was tired of outdoor PIR sensors that was unreliable. I've had it installed for about a month now, and it has not missed an event yet. It gets used 3-5 times a day. Also, only one possible false trigger during a heavy snow storm, but we also have deer around here that could of tripped it. It's a little hard to set up, but once zeroed in it appears to be very very reliable. I changed it to the high sensitivity, which isn't the easiest to do. I just purchased a second set of sensor for the other driveway. I am concerned because the placement of these 2nd set does not allow direct sun to hit the vertical photocells for charging the batteries. It would be nice if there was an optional remote photo array for charging the batteries. I also use the receivers relay outputs to trigger other security and smart home devices. So far, I'm very satisfied with these!

Like this product a lot. It is exactly what I needed. We live in the country and have a long driveway. We don't get many visitors but when they do come they surprise me when they ring the door bell. Now I know when someone is coming. The base is about 300 ft from the sensors inside our block house and we have never had a problem with receiving the signal. It took some work to get the sensors installed and aligned but it wasn't hard, just tedious. The sensors have a view hole to check the alignment and a digital indicator to show how well they are aligned. I really appreciated the mounting hardware included that provide for many mounting options. Included was a sheet from the vendor with links to Youtube videos and an email for contacting them. They were very responsive to a curious question I had. I am a satisfied customer.

I set-up my alarm system about a year ago using HTZSafe as the core for the alarm system. I have the HTZSafe laser at the front gate about 400 feet from the controller that goes through about 5 walls. I have the HTZSafe radar detectors mounted around the house that transmit between 3 walls up to 5 walls. I purchased a auto dialer shown in my pictures. It actually sends SMS text messages through the internet to multiple cell phones when the front gate laser detector is triggered. The auto dialer also has the capability to send out voice messages when triggered. To trigger the auto dialer I use the 12 volts DC produced by the HTZSafe controller. Additionally at a later date I can add more auto dialers to be triggered when the HTZSafe radar detectors are triggered. I did take the HTZSafe controller apart and soldered a audio wire to run the tones through a 4 speaker Lepy amplifier. I then installed in ceiling speakers that the Lepy controller is connected to. When the HTZSafe plays its tones you can hear them through-out the house. I then installed a relay that is triggered when the HTZSafe controller is sent an alarm signal. It causes lights to flash and supplies power to a 12 vDC power supply that triggers audible sirens. I then use MyQ switch connected to our Chamberlain garage door opener that allows me to turn on/off the alarm system via the MyQ application on my iPhone. I then use the SV3C cameras sold on Amazon to check the house out if I get an alarm signal via the auto-dialer. We had tons of theft after I installed my alarm system no more theft. Totally shut the theft down. No one can get even close to the premise before the alarm system going off. The HTZSafe laser detector is rock solid. It HAS never had false signal. If it signals the HTZSafe controller a person/car has triggered it. The advantage I have using the SV3C cameras is they can play through our ROKU Tv's as well as our iPhones and a free ware application called iSpy that runs under Windows. This allows a excellent solution for video security. The SV3C cameras also have motion detection capability as well as 2 way audio so you can listen and talk through the cameras. On a motion detection I'll get an alert on my iPhone.

This product does very well detecting an intruder breaking the invisible beam. I don't yet know if the solar panels will keep the internal battery sufficiently charged. So far so good on that score. Setup was relatively easy. Instruction sheet clear enough.

The supplied mounting hardware was a disappointment, but easily corrected with replacement hardware from the home improvement store. Specifically the holes in the sheet metal didn't line up and were too small for the supplied machine screws. Not all of the nuts supplied with the screws fit.

Knowing this I would buy it again and recommend it to a friend.
