Wuloo1800 Ft Wireless Outside Driveway Alarm Outdoor Motion Sensor & Detector Driveway Alert System, Rechargeable Battery/Weatherproof/Mute Mode/Clock and Alarm Functional (1&4-Camouflage)

I followed the directions and fully charged all sensors until the green light came on for each of them. I installed all four sensors and they worked fine. However, the next morning none of the sensors would work. I live in a remote area of Alaska and it was hovering on zero degrees Fahrenheit . I assumed that something happened and the batteries lost their charge, perhaps due to the cold temperature. I brought all four sensors inside and lo and behold after an hour, all four sensors began working . Obviously the cold kept them from working outside. There was nothing in the enclosed literature identifying what temperature range they would work in. Thanks to Amazons return policy I was able to initiate a return.

I purchased this product as I live out in a rural area. I have placed one at my driveway entrance and others around my property near other entrances. These are extremely sensitive (which I love) and seem to reach much, much further than the 33' suggested. The higher up these sensors are placed the further they reach so play around with the height. I set them then walked around with the base to see where motion/I was picked up etc. Very easy to install - very easy to use. They do take a long time to charge being as there is only one charger included with a special end to fit each sensor. Each one took quite a few hours to fully charge. They will 'chime' if wildlife passes by - and also if they pick up branches or leaves blowing in the wind. One can set the chimes to different rings so you'll always know which area has detected motion if you cannot see the base. With an 1800' range these will work for most properties.

I live in a rural location and want to be alerted when I have visitors (wanted or unwanted). I purchased a set of these to place at my driveway entrance and around my house. They worked great. So several months later I purchased more of these and placed them around my barn and other areas outside my home. They work great.Make sure you read the instructions, place them properly and then adjust the sensitivity. Very few false alarms and the two sets work together for up to 8 cameras. Many different alarm tones to chose from, so I can tell just by the sound which sensor is being triggered. Solar works great and batteries too.

I like knowing that my homes surroundings are safe by the use of this alarm system.It’s easy and to the point to install.I recommend this driveway alarm to anyone that would consider the extra layer of protection you get from getting a heads up from any movement around the house.Place sensors in areas that are not directly facing traffic. Use it as a trip wire type of setup to avoid unwanted alarms throughout the day.

The sensors did not work more the 5ft from the base reciever. And when sensors next to base Station, they were not work consistently. Do not buy this product.
