Stemar Shop (originally launched as AjaxAlarm.co.za in 2019) is the official online store of Stemar Security Systems. While we continue to offer technical services to our local communities in Johannesburg and Cape Town, our online product range is gradually being consolidated into one website. During this transition, you are welcome to shop on either website until the migration is complete. We appreciate your continued support.
