CPVAN 125dB Loud Motion Sensor Alarm with 328ft Remote Control (40ft PIR Detector, Batteries), Indoor Wireless Infrared Security Motion Detector with Siren for Home Garage Van (CP2 Pro, Black)

I am so happy I bought this. Despite having two clean cat boxes to choose from, one of my three cats kept pooping in the same living room corner. This alarm was easy to set up. When the cat walks by the sensor it beeps twice and they move along. So far in 16 days no poop! It has two settings, the 2 beeps, and then a very loud, wake up your house is on fire alarm that I accidentally set off once, that one you have to physically turn off. The two beeps one goes off and resets itself with no problem, it's set and done. A simple, inexpensive solution for me.

These alarms are great. I just bought my 2nd one recently. The range is good--I have them high up near the ceiling in a high-ceiling studio apartment and they detect movement without a problem. They are extremely loud and make the normal alarm sound you’d hear if you had a higher-end alarm system. These remotes are excellent, too, because they can arm/disarm these from outside the residence, through walls. There is no need for line-of-sight. I arm/disarm these while in my vehicle in the driveway with zero issues. Pairing remotes to another unit is very easy; as well, so you only need to use one remote for multiple alarms, which allows you to give another remote to someone else that would need it. The only downfall is if you plan to use batteries for the power source you’ll be replacing them about once a month (that was my experience using name-brand batteries and arming/disarming pretty frequently). I suggest you do what I did and get a USB-Micro USB (https://www.amazon.com/Micro-USB-to-Cable/dp/B004GETLY2); you’ll also need a USB wall charger. Or, you could an ac power adapter. Either way, I wouldn’t use the batteries as the primary power source, as it’s worth investing in a constant power source, and leaving the batteries in just in case power goes out.

Easy to install. Set up requires a bit of trial/effort because the remote included does not match the remote in the instruction booklet. The icons on the buttons are different than the illustration and therefore have different functions than given in the instructions. I am using this in the ceiling of an outdoor pavilion to scare away raccoons that have been doing a lot of property damage. This sensor is probably meant to detect humans much larger than a raccoon, but it did eventually sense the raccoon at about 12 ft away. The alarm sound is quite loud and stunned the raccoon for a couple seconds before running away (got it on video). The light is just a red flashing light that is not very alarming at all. I was hoping for something like a blinding strobe but couldn't find the loud alarm and flood light in one unit anywhere. I have a very sensitive camera in the same area that senses the critters quicker than this alarm does, but with the remote I can manually set off the sound alarm without going outside. The remote seems to have a good strong PIR. It works from inside closed windows, across 30ft of yard and through the pavilion curtains. Handy on these very cold winter nights.

LOVE THIS!! I got three motion detectors to protect my empty rental while I was waiting to find new tenants and the new tenants moved in. I am on good terms with the neighbors around my rental property, so they knew if they heard something to call or text me. There was a time or two I did set these off, initially to make sure they worked and then once accidentally when I went over to check on something in the garage. My motion alarm in the garage, it blended in nicely with other items on the garage's work bench so IF it had been someone breaking in to steal my new kitchen appliances or whatever nefarious goals a burglar might have had, it would surely scare them off. I was sure scared when I did it by accident!The kitchen and front door alarms were not so well hidden since my rental property was empty waiting on tenants to occupy. However, I kept the front door alarm turn off remote at my own home with me, and then had the alarm remote for the next in series sort of near the next to be turned off so I could make my way through the home without setting it off. However, the time I set alarm off accidentally was my own fault for not remembering to get that last on/off button and turning off the garage-based alarm before I went out there.There are so many uses for these! I highly recommend these.In case Amazon puts similar products together, this is my product's description:CPVAN 125dB Loud Motion Sensor Alarm with 328ft Remote Control (40ft PIR Detector, Batteries), Indoor Wireless Infrared Security Motion Detector with Siren for Home Garage Van (CP2 Pro, Black)I hope this review helps others.

This alarm is super affordable and super easy to set-up. The on and off symbol on the remote are very hard to tell apart, but the deal-breaker for me was the false alarms. I was using it to provide coverage near my bedroom as part of a larger (but wired) security system. It randomly went off in the middle of the night and thank goodness I didn't call the police. Nothing triggered the wired system and I was able to verify it was a false alarm which is completely unacceptable for my particular use.For outside to scare away raccoons or as a chime, where a false alarm is only a nuisance, this would be a good purchase. But not when your personal safety is involved...
