Nippon America 110V Outdoor Alarm Security Siren (TC-S7545-110), 80W Wired Horn, 120dB Long Range Sound, Wi-Fi Socket Included for Remote Activation, Weather Resistant, 8ft Cable

It's loud, easy to install.

This is very loud. Works great. I hooked it to a WiFi switch for outside. Next time the car thieves come around, they will get horn. Highly recommend.

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.

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 is so loud that you need to wear protective ear covering when plunging it in for the first time. I did not see any reviews for this product but went ahead and purchased it based on the product description. In any event, this seems more than adequate for the job of deterring any would-be intruders. I may update this review in a few days or so, based on further use.

Loud enough only down side is the cable that is described in the details are 8ft long cable, but in reality the one that I got is only 6ft long, very disappointed in this aspect.

This is very good, This is not only helpful for my students to wake up in the morning but also my neighbors are getting up early.thank u Nippon America.

This is Great!!! its LOUD, works with Alexa app. Wish I can use this Siren with my existing home alarm.

Siren arrived three days short of a month. Customs delayed it, I live in alberta Canada, I believe it was shipped from Indiana or someplace in USA... That was a long long long wait. The box was very beat up, post office put a bag around it apologizing saying this is how they got it. Lady at post office said to take pix, which I did. However, upon opening, there was no damage and the unit works. It came with absolutely no screws for mounting unit to wall, but there are several holes... Unit was tested facing down, and I bought two Kasa KP400 dual outlet Wifi smart plugs to activate this siren from my phone.... Found the Kasa App on Apple Store, didnt show up on initial search. Went to Google Store, it was there but it asked me to create an account. Went back somehow through that to Apple Store and searched on diff bar and it showed up. Kasa App asked for location. I allowed it for set up, then deleted access. App is pretty complicated, took a bit going to all menus, but kasa came with setup info, and screws to mount to wall... Had to pair with my internet wifi hub, name the ports, and NO, I dont have Alexa or Google I dont trust a machine recording everything I say, that is big brother shid I dont need. Used a photo of siren to designate plug name, needed access, then deleted camera access and location after install and now I can turn on siren from Kasa app on my phone when away from home. I needed a siren which activated simply by plugging into outlet, and this one fit, so lucky for me, I got what I wanted, for once... Highly recommend... worth the wait. Kasa smart plugs showed up in two days... those are cool and I recommend those as well. Got them on Amazon. KP400 UPDATE: Not as loud as they claim, seriously, my old siren was much louder... depressing after waiting a month.
