Nippon America High Decibel High Power Outdoor Alarm Security Siren (TC-S7545-110), Long Range, 80 Watts, 120 Decibels, Remotely Activate with Wi-Fi Socket (Sold Separately)

Awesome! So loud! If some is threatening you or your family, this will notify a 1/4 mile radius! Awesome! If you live in a noise sensitive area, get something with an adjustable db level. This is for intruders (don't cry wolf) and to scare away annoying motorcycles or ebikes doing wheelies in front of your property! I already used it to break up two different fights 100 yards away (they immediately broke it up and took off, hope it saved a life). The real deal, water resistant, and easy to use with a power strip, extension cord, and/or smart plug. It is loud and deep. Sooooo worth the money

This arrived quickly and in good condition. It's a sleek, streamlined siren which feels sturdy and definitely makes a good amount of noise when plugged in. It's good to have a variety of options if you suddenly find that you need to sound off to scare away intruders -- some built in on your cameras, some free-standing wi-fi sirens mounted in strategic spots, some sirens with plugs like this one, which could be activated quickly even if someone is using a signal jammer. Couldn't be easier, plug it in for "on" and pull the plug for "off." This one can definitely be controlled with an Alexa plug if that's what you want to do, but remember to choose a device name that won't come up often in ordinary conversation to prevent unfortunate accidental voice activations. It's versatile and not terribly expensive.

I was pleasantly surprised at the quality and loudness. I agree with others it would be nice to have an on/off switch but with a smart socket it works fine. My only other suggestion for improvement is a longer AC cord. I use mine outside under a covered patio and options for placement are limited. At minimum it should be 12 feet long, maybe longer.

I read the info about the alarm carefully and had my own switch to use to turn on the alarm when I needed to, otherwise I have no idea how someone would use it. For my purposes this was exactly what I wanted and had to explain what I was doing when I tested it for a few seconds as it is indeed very loud!

This thing is so loud! Perfect for me. Hooked it to a Wyze smart switch set to go off when it sees someone.

i installed the system extremely easy even using a amazon smart outlet, now i can blast out loud noises against property trespassers from the comfort of anywhere, noise is loud and annoying as an alarm should be

It would be nice if it was possible to change the sound style of the alarm.

I attached this to a toggle switchand then to my Christmas decorations. That way when someone attempted to steal my Christmas decorations when they pulled the decoration, the siren would sound

Loud
