For 30 years we have been based on the needs of consumers and their lifestyles to think and manufacture affordable and high-performance products.

We are Siera, a company developed by highly experienced engineers, sharing knowledge, experience, and a passion for quality and excellence.

With our own manufacturing and design (first in Portugal, then in Korea, and now from our headquarters in Hong Kong), we develop products based on the needs and lifestyles of our customers, providing innovation, comfort, and security to consumers.

In the 1990s, electronic technology expanded and diversified into various areas. Since 1995, Siera has been strongly focused on the then-emerging Electronic Security segment, with a clear objective: to make Siera a benchmark in the sector, providing innovative, affordable products and a highly qualified, personalized after-sales service.

Determined to follow our own path, our mission is to change the game in the world of Electronic Security by manufacturing quality products at competitive prices, with the great advantage of support and respect for commercial agreements.
