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.

Easy to sync with Eufyh app and is loud when triggered
I needed something to sound an alarm outside if something triggered my shed PIR sensors...this is just the job. Paired with the Eufy app within seconds and after setting the app to sound the siren if wither of the PIR's were triggerd the siren was good to go. Using the template provided it was easy to drill the holes to mount the siren on the outside wall next to the shed. I tested it by triggering the PIR in the shed and the alarm is more than loud enough to do the job as intended. Quality feels good and with a 2 year battery life it's just what I needed. 100% 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 👍

Very happy with it
Was hunting for it for awhile while and read very mixed reviews until i decided to buy it and i dont regret. Very solid and sturdy item. Regarding the sound, well yes its not that loud what you would expect but to be honest its loud enough in the quite night. So yes very good. Price, you have to hunt for a sale.

Loud and reliable !
Another great addition to my security system. Easy to set up like all Eufy products, easy to mount thanks to a swivel on feature. Includes 2yr batteries. I like you can amend the sound level as it is loud which is exactly what I wanted. Compliments a single camera as an alarm or a full system. This works with my 8 cameras and door sensors perfectly.

Adds a much needed sound upgrade to the Eufy system
This siren turns the Eufy security system into an actual usable product - without it the pathetic homebase alarm isn't loud enough to even scare off a cat. This punches out a nice high-pitched siren - not very loud, it won't alert the whole street, but loud enough to alarm an intruder and wake up your next door neighbour. Like all Eufy products adding it into the mix is a breeze - quick and easy with the app. My big issue with this is it says install in a sheltered location as it's weather-resistant not waterproof. That's a big down side for me, as the whole point of a siren is surely to install it in an external location.

Save your money
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.

Seguridad garantizada
Esta marca es sinónimo de calidad. Yo tengo todo el sistema de seguridad de eufy y productos de su otra marca que es Anker. Sirena que deja graduar el nivel sonoro y muy fácil de instalar y emparejar. Recomendable

Luid alarm om inbrekers af te schrikken
Omdat ik al een aantal Eufy-camera's in gebruik heb, zocht ik een manier om het alarmsignaal goed hoorbaar te maken naast de app-notificatie. Een inbreker moet immers ook afgeschrikt worden. Deze eufy Security Sirene is daarvoor de perfecte uitbreiding. De installatie via de app was binnen een minuut gebeurd. Hij koppelde moeiteloos met mijn HomeBase 3. In de app kun je eenvoudig automatiseringsregels instellen, zodat de sirene direct afgaat zodra een van de camera's of bewegingsmelders personen detecteren. Met 105 dB is het geluid behoorlijk hard en indringend; dit schrikt eventuele ongewenste gasten direct af. Ik heb hem binnen hangen, maar als je heb buiten hangt (hij heeft immers IP-65-certificering), dan horen de buren het ook meteen. De batterijduur belooft 2 jaar mee te gaan, wat erg fijn is omdat je er lange tijd geen omkijken naar hebt. Ik heb hem al ruim een jaar in gebruik en hij lijkt die belofte waar te maken. Ik heb nog geen batterij hoeven vervangen. Voor deze prijs een onmisbare upgrade voor je beveiliging.
