Eufy Security Siren vs Heiman Smart Siren HS2WD series

The Eufy Security Siren wins overall on price, battery life and rated sound level. The Heiman Smart Siren HS2WD series answers with broader smart home integrations, supporting both Samsung SmartThings and Home Assistant, where the Eufy Security Siren has none.

How each connects to a smart home. The Eufy Security Siren only works as an add-on to a Eufy HomeBase, with no third-party integration at all. The Heiman Smart Siren HS2WD series is a Zigbee device that needs a Zigbee hub but then plugs into Samsung SmartThings or Home Assistant directly.

The Eufy Security Siren runs on 2x CR123 batteries rated for about 2 years, with no wired option. The Heiman Smart Siren HS2WD series can be wired for continuous power or run on its built-in battery, which is rated for about 12 hours rather than long-term standalone use.

The Eufy Security Siren, rated up to 105dB, is louder on paper than the Heiman Smart Siren HS2WD series' rated 95dB. The Heiman Smart Siren HS2WD series adds a flashing red LED as a visual alert, a light component the Eufy Security Siren does not have at all.

Choose the Eufy Security Siren if you already run a Eufy HomeBase and want a cheap, longer-lasting, louder-rated companion alarm, and you do not need native SmartThings or Home Assistant support.

Choose the Heiman Smart Siren HS2WD series if you run a Zigbee hub and want a siren that plugs directly into Samsung SmartThings or Home Assistant, and you are comfortable buying a device with no established owner review track record yet.
