PGST Tuya PIR Horn Siren: Smart outdoor alarm – affordable, effective, and with no hidden fees

A secure home brings peace of mind. Yet many people still believe that a reliable alarm system is expensive, complicated, or only suitable for large houses. Fortunately, in 2025, smart home security has become affordable, easy to install, and extremely effective. The PGST Tuya PIR Horn Siren is a great example of modern technology made accessible for everyday households. For just €19.69 including VAT, you get a powerful siren with motion detection, waterproof housing, and support for well-known smart platforms such as Alexa, Tuya, and Google Assistant.

What makes this siren unique is that it can be used as a standalone solution or as part of a full PGST alarm system. Many users connect it to a central hub, but you can also use it alone as a deterrent. Customer reviews highlight that the siren is very loud and reliable. Outdoors, this is essential – a loud alarm often stops an intrusion before it happens.

Reliable detection – day and night

The motion sensor uses infrared technology and triggers the siren or sends a notification when movement is detected. This creates a smart combination of passive monitoring and active security. Ideal for driveways, gardens, garages, sheds, or business properties.

In addition, the system is waterproof, making it suitable for rain, wind, and winter cold. This is an important feature that many cheap alternatives lack.

Smart integrations – less hassle

This siren works with popular platforms such as Tuya, Alexa, and Google Assistant. You can integrate it into routines, automations, or receive notifications directly on your phone. Two versions are available:
– “No PIR Horn” – siren only
– “With PIR Horn” – siren + motion sensor

A customer from Spain wrote:
“Product conforms to the description, associated without problems with the PGST control unit. Very loud sound.”

That’s exactly what you want: no hassle, real results.

No hidden fees – customs stress is over

In the past, ordering from AliExpress could come with unpleasant surprises: customs fees, handling charges, and delays could increase the cost. Today, AliExpress calculates and includes VAT and any fees upfront, so you don’t face unexpected costs upon delivery. The price of €19.69 already includes VAT and you won’t pay extra customs or administrative fees. Check the current price here: https://s.click.aliexpress.com/e/_c4tT7IVJ

In addition, AliExpress often offers free returns, while dropshippers charge high fees and sell this same product for €49 or more. Don’t overpay on unknown websites.

Smart security at a smart price

The original price is €66.42, but you now save €46.73. The promotion runs until December 14 at 23:59 MET. There is also an additional coupon of €2 off purchases over €15. See the offer here: https://s.click.aliexpress.com/e/_c4tT7IVJ

In practice, this means that for just a few euros you get a powerful, professional outdoor alarm module for your home or business.

For businesses – without monthly fees

Many businesses use expensive alarm systems with monthly subscriptions. This siren is a great alternative:
– Self-installation
– No monthly costs
– Immediate deterrence

Compatibility?
Yes, according to users, it works with PG107 and PG108 systems, and pairing is easy through the app.

Tip: avoid paying more at dropshippers

More and more dropshippers resell AliExpress products with 300–800% markup and poor return policies. Shop smart and buy directly. Official link: https://s.click.aliexpress.com/e/_c4tT7IVJ
