Heiman Smart Siren HS2WD series vs Netatmo Smart Indoor Siren

The Netatmo Smart Indoor Siren edges ahead overall, winning on price, battery life, sensor coverage, sound level and presence-simulation sounds. The Heiman Smart Siren HS2WD series answers with native Samsung SmartThings and Home Assistant integration, which the Netatmo Smart Indoor Siren lacks entirely.

How each one connects. The Heiman Smart Siren HS2WD series is a Zigbee device that needs a Zigbee hub but then works with Samsung SmartThings or Home Assistant directly. The Netatmo Smart Indoor Siren pairs exclusively over Bluetooth to a Netatmo Smart Indoor Camera and has no other smart home integration.

The Netatmo Smart Indoor Siren includes a vibration sensor to detect deactivation attempts. The Heiman Smart Siren HS2WD series has neither a vibration sensor nor a tamper sensor.

The Netatmo Smart Indoor Siren runs on 4x AA batteries as its primary power source, rated for about 2 years, or can be wired if preferred. The Heiman Smart Siren HS2WD series can be wired for continuous power or run on its built-in battery, rated for about 12 hours rather than long-term standalone use.

Choose the Heiman Smart Siren HS2WD series if you run a Zigbee hub and want a siren with native Samsung SmartThings or Home Assistant support, and you don't need presence-simulation sounds or a vibration sensor.

Choose the Netatmo Smart Indoor Siren if you already own a Netatmo Smart Indoor Camera and want a louder, more feature-rich alarm with vibration sensing and presence-simulation sounds, and you don't need third-party smart home integration.
