Very easy to set up and install and has usb cable so could charge and set up without solar charging. Love the ease of the remote and one button set up. It was very intuitive. Only complaint is that it is reasonably loud but bought others at the same time and all supposed to be 120 db and this one was the quietest of them all. Would be loud enough at night but may not be during the day with tv on etc. To turn off after it triggers on is a long press of any button on the remote which is handy when wanting to stop the alarm but takes about 2 seconds to turn off so it’s not instant. Another one I bought had an OFF button on the remote so is instant turn off which is a better feature as at night 2 seconds to turn off with an alarm going can be annoying. Can be used indoors as it has usb charger and east to install. Just one screw into wall and hook it on the screw. Easy to remove as well. Overall happy with the purchase but if you want a really loud alarm then don’t buy this one.

Using this device in the driveway. It works great and the price was excellent.

Had and incident where MAGA cultists entered our yard and tore down and stole a Harris Walz 2024 banner over our garage door. Mounted this on a porch post so that no one can approach that area without setting off the alarm and flashing red light. It's not super loud but loud enough that we can easily hear it and respond appropriately. Remote works well and is best kept in your pocket so you can tap any button and shut it down easily. Holding down any button for 5 seconds shut the unit off which is handy. When mounting it somewhere insure that it gets as much sun as possible so it has a good charge and can function. I suggest that no one mess with the internal battery because it's a LiPo and if damaged can give you a small but fiery explosion and fire that you will NOT like. I've seen them go off in airsoft AEGs (guns) and it's a mess.To date the only times it goes off is when the family cats pass it or one of us trips it, but it's loud enough to alert us and easy enough to deal with by remote. After next Tuesday this will be a moot issue but I may redeploy it to a fence section to deter bears that have been raiding the neighbor's garbage can.

I really like this product. It has a hard time operating in winter low light conditions and needs a lot of external charging. Worked great for about a year and this year it just stopped working and will not power on. It appeared to have water inside the device.

Tiene plasticos de calidad aceptable. Me gustó el control para modos de alerta y tiene buen sonido. Lo ocupo para vigilar una casa y es muy efectivo.-Lo que no me gustó es que al sonar la alarma solo dura como 50 segundos.....Deberia sonar hasta desactivarla manualmente .

Product stopped working and I had to open up the back and uninstall the battery and then reinstall the battery for it to function again. This has happened randomly about 5 times now. I have to take it down, open up the back and take the battery out and put it back in for it to function. Extremely inconvenient and most people would most likely just think it was broken. Not sure if it is just a faulty unit but it's definitely something to consider if you plan to purchase this product.

Es una opcion economica para alarma, aunque poco practica porque si no tienes la precaucion de tener a la mano el control y te olvidas cuando pasas cerca se activa. El sonido si es fuerte. Lo que no he logrado averiguar es como apagarla y es que me refiero que en mi caso la necesito solo para usarse en las noches ya que la instale en mi patio, y en el dia como lo comento a veces olvidamos y con el simple hecho de pasae suena.

I purchased two alarms four months ago to help protect my puppies from coyotes insistent on getting to them (pups are well and fine, now 7 mo old). Once set for alarm mode at night and placed into position, they worked very well for my purpose. I only had two spots on my courtyard wall that were low enough from the outside for coyotes to jump, so I placed both alarms in that location. One alarm was simply set on the wall itself, and the other was zip-tied to a pole outside the wall from where a past propane tank gas line had been run and no longer used - simple setup for placement. The alarm was triggered multiple times by the coyotes and appears to have stopped them from jumping my 6-foot outside perimeter fence (as noted by lack of territorial scat markings). I'm thankful to have found an inexpensive solution because the multiple motion sensor spot lights I have throughout the one-acre yard was not doing the trick! Of note, my puppies have also triggered the alarms, which scared them at first. They are no longer afraid of the alarms but steer clear because they don't like the sound, so I'm assuming it works the same way for feral animals, which means they will be trained to stay from a certain area but might try to find a different path. For the price, I am buying more alarms because I live in Arizona near the Mexico border and have a problem with illegals crossing my property and camping out on the two acres below, cutting my barbed wire fence and damaging my property. While I do not have neighbors really close like when living in a housing tract, sound carries here, so I will most likely only use a few alarms in select locations in alarm mode and try out the motion light function in other areas where the sound could bother my nearest neighbors. I doubt anything will stop illegals from coming through my property because it is an ongoing problem, but I'm hoping it deters them from having the time to cause further damage and feel comfortable enough to sleep below my windows!Things that might be questioned;Set up is fairly simple, but I was not successful in linking the remotes no matter what I tried - not a biggie on my part.Remote door needs to be slid down in order to find control buttons.Alarms did not function properly the first week due to needing to charge power again from electrical outlet. Once they were charged a second time, they have worked fine since off of solar. If you live in an area where the sun does not always shine brightly or the alarms are triggered frequently, they might need to be charged from electrical outlet.I have had multiple false alarms due to strong winds and strong rainstorms, which is most likely due to warm air swirling around with the temperature differences. Again, not a biggie where I live because I don't worry about the alarms bothering anyone (they can be annoying to you though).When triggered, the alarm will automatically shut off and go back into sensor mode after about 30 seconds. On one occasion, one of the alarms went a little whacko and kept going off for about 5 minutes. Thankfully, it re-set itself by the time I was going to go out to see why it wasn't shutting off. It appears to be working properly since that time.All in all, I am happy with my purchase and think it was a good buy because the alarms can be moved and used in different areas, so they will most likely be used until they no longer work (hopefully, not for a long time - but if not, still worth the price because they did what they were intended to do).Hope the information helps!

I had the cheaper, smaller, semi-round alarm light, and this is a better product. The old one fell off our fence in the dirt several times and stopped working after a year. This is a stronger design than the cheaper one and works as advertised. I am especially happy that it effectively covers the area behind my garage and trailer storage. It stops at the black metal fence (far left in photo) approx 25 ft. from where it is mounted and does not fire off when when cars or people go by outside the fence.Addenda: it is early Feb. 2021, and the new one is working great!
