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

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.

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.

I bought the Siren to add to my existing Eufy security setup, and overall, I’m happy with it. Setup was incredibly easy and it connected to my HomeBase straight away. It’s also compact and doesn’t stand out too much, which is great for discreet placement. A lot of reviews mention the volume, and yes, it’s not the loudest siren out there. If you're expecting an ear-piercing alarm, this might not be for you if you want to use it outside but indoors it definitely is loud enough. That said, it’s still loud enough to grab attention, especially indoors. I also like that you can adjust the volume and change the alarm tone, so it’s not overly harsh. One thing I appreciate is that it runs on battery backup as well, so it won’t stop working in a power cut. It also reacts instantly when triggered, and because it’s wireless, there’s no complicated installation. If you already have a Eufy security system and just want and extra layer of security, this is a decent addition. It’s not the most powerful siren but pacts a punch.

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.

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.

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.

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.

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.

Die Sirene funktioniert einwandfrei und erfüllt ihren Zweck zuverlässig. Die Einbindung in die HomeBase 3 verlief problemlos. Ich bin sehr zufrieden und würde die Sirene jederzeit wieder kaufen. Nachtrag nach über 4 Monaten Nutzung: Die Sirene arbeitet weiterhin absolut zuverlässig. Es gab bislang keinerlei Verbindungsabbrüche zur HomeBase 3. Ich nutze sie bewusst als zusätzliche Absicherung, falls eine Push-Benachrichtigung einer Kamera einmal ausbleiben sollte. Die Sirene ist zentral in der Wohnung platziert, die Lautstärke steht auf „niedrig“ und ist dennoch vollkommen ausreichend. Im Modus „Zuhause“ ist die Sirene bei allen Kameras aktiviert. So werde ich – insbesondere nachts – zuverlässig über Bewegungsalarme informiert. Voraussetzung ist dabei die eigene Anwesenheit, da es sich um eine akustische Zusatzabsicherung handelt. Die sehr laute Sirene der HomeBase 3 setze ich bewusst nur im Modus „Alle-Nacht-Alarm“ ein. Für den Alltagsbetrieb ist die separate Sirene für mich die deutlich angenehmere Lösung und eine sehr sinnvolle Ergänzung zum Eufy-System.

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.
