eufy Security Siren, 105 dB Wireless Alarm, IP65 Weatherproof, Remote Alerts, 2-Year Battery Life, HomeBase Required, Compatible with HomeBase S380 and S280, App Control, Easy to Install

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.

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.

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 👍

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.

Works well very loud ,easy to install

Total rubbish. They are supposed to have a smoke alarm listener in the box - there isn't. The unit is supposed to "hear" smoke alarms and then be set off. My two failed to do this. Also even if they did work you would then have to have them indoors - defeating the whole point of having them! Mount them outside and you lose that functionality. The siren is no louder than the homebase 3 built in alarm. These are just cheap and nasty noise extenders - save your money. Mine are being returned. I've spent days talking to tech support - no help at all.

Not at loud as other brands but it's the only one that works with the eufy system.

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.

Jeden z produktów eufy na którym się nieco zawiodłem,syrena jak na syrenę jest zwyczajnie cicha.

Prodotto di Ottima Qualità, così come tutti i prodotti Eufy.

Perfectamente sincronizada con Home base 2. No entiendo todavía porque no se comercializa la sirena. Funciona perfectamente.

Uppfyller helt mina förväntningar. Snabb leverans.
