Would recommend
Part of the Eufy Alarm and cctv system. Works very well. I have 2 front and Back. Easy to set up, installation and the app does everything for you. Very loud, never had a problem. Would recommend.

Loud and easy to setup. Great for 2-3 bed standard size house
This siren is a big step up from the Eufy home base alarm – it's noticeably louder and makes the system feel much more effective. I really appreciate that you can add multiple sirens through the Eufy app, which is great if you want alarms both inside and outside, or on different floors for better coverage. While it's not the loudest alarm I’ve ever heard, it's more than sufficient for most 2–3 bedroom homes. Id class it about the same loudness/ possibly slightly louder than a standard house fire alarm. Definitely a worthwhile addition to your Eufy setup so I highly recommend.

Very good siren
I was reluctant to purchase the siren after the reviews I have seen for the product, but I was pleasantly surprised. The siren is quite loud, but of course, it could do to be louder in some circumstances. Indoor use, you won't have a problem with at all, but outdoor use, it can be a little too quiet depending how loud an environment you live in. If you want to make the most of this siren outside, you need multiple, but they are quite affordable for the most part. They released this product originally with a sound that was more like a reversing truck than an actual alarm, but I can say it has since been updated and now sounds like the product it's supposed to be. The settings in the eufy app for this siren are quite lacking; not that an alarm needs that many features, but after initial setup, there isn't even a way to test the loudness without setting off a trigger. At least they have fixed the alarm delay. There is only low and high options, and it is automatically set to low by default. So if you think it is too quiet, do check the settings options first. I will be getting more of these to put outside, both front and back of my house. It is IP65 weather resistant, not waterproof like the rest of their products, so be careful where you decide to place it. But it's well worth it's money, and I am impressed 👍

Good addition the system.
Not as imposing or loud as a traditional alarm box but can certainly be heard and turns the system into a proper alarm. Defiantly worth having.

Loud and gets your attention
Nice and loud! I have triggering when a frost/leak sensor is triggered giving us time to fix the issue before it becomes a crisis. Connected easily and quickly to the base station. Not tested it outside but seems to be specked to be being ip65 weatherproofed , may get another one and mount it on the outside wall.

Good sound, alarm duration not adjustable
The volume of the siren is good, and it seems they have updated the siren alarm tune to be that of an actual siren rather than the “reversing truck” which I saw on previous reviews. However I am very disappointed that you cannot adjust the duration of the alarm. It sounds for about 30 seconds and then switches off which is quite obviously not enough. Even the Homebase and the cameras stop sounding their alarms after 30 seconds. Overall Eufy is not a great solution to use as a security system because of this major flaw, even though it’s quite effective as a monitoring system

My grans dogs rear is louder after leftover Sunday roast.
I was pleased as punch to find out there was a "loud and audible" siren for my security system, was easy to setup as all eufy items are. Going through testing and how dissapojntwd was I, seriously my grand jack russell can produce louder gas than this waste of money. I don't have no doubt my propery is no more secure than before. I really think that I've wasted far to much money on this junk.

Easy and quick to set up
I needed this because I have now set my base station to work on wireless so that it can now be moved to a secure location. This means that any evidence is more likely to be preserved
