  1. Samuel Collins –

    I bought this Dahua indoor siren from apsardze24.lv for my home setup. It’s surprisingly compact but packs a punch at 105dB—it’s seriously loud! Setup was a breeze with the wireless connection, and I love that it also measures room temperature. Very satisfied with the quick delivery from the store, too.

    Samuel Collins –

Can I integrate the Dahua ARA12-W2 with third-party smart home hubs?

Compatibility with third-party systems depends entirely on the specific protocols supported by your existing controller. To ensure you have the correct configuration for your specific setup, we recommend contacting our technical support team at [email protected] with your hub's model information for professional advice.

How loud is the ARA12-W2 Dahua wireless indoor siren and will it be audible throughout my home?

The ARA12-W2 produces a sound pressure level of 105dB (±3dB). From our experience, this is exceptionally loud for an indoor device—comparable to the sound of a power drill or a motorcycle engine at close range. For a standard residential or office layout, this volume is more than sufficient to alert occupants and effectively deter intruders.

Is the wireless communication signal of the ARA12-W2 secure against hacking or jamming?

Yes, this siren utilizes 868MHz two-way communication protected by AES128 encryption, which is the technical standard for high-level data security. The ARA12-W2 also features frequency hopping technology to prevent signal interference and jamming, ensuring a stable and secure connection to your alarm hub within a range of up to 1,000 meters in open space.

Where is the ARA12-W2 shipped from and how fast can I expect delivery?

All our stock is held in our local warehouse in Riga, meaning there are no long waits from foreign distributors. Once your order for the ARA12-W2 is processed, delivery to addresses in Latvia, Lithuania, or Estonia typically takes only 1-2 working days.

How long do the batteries last on the Dahua ARA12-W2 and how will I know when they need replacing?

The device is powered by two CR123A batteries, providing a lifespan of approximately 2.5 years based on typical usage (triggered twice weekly). The ARA12-W2 includes a built-in low battery alarm and signal strength detection, so you will receive a notification via your security system well before the power is depleted.

What are the benefits of buying the ARA12-W2 from an official partner like Apsardze24.lv?

Purchasing official equipment ensures you receive the version specifically intended for the Baltic region, which guarantees full cloud security and stable firmware updates. As an Official Platinum Partner, Apsardze24.lv provides only certified goods, so you can be certain your device will remain compatible with official apps and local server updates.

What happens if my Dahua ARA12-W2 develops a fault after installation?

We provide a comprehensive 2-year warranty on the ARA12-W2. If you encounter any technical issues, the warranty service is managed locally in Riga. This provides peace of mind and a much faster resolution compared to 'grey market' devices that often require shipping back to international sellers for repair.
