Security Alarm Systems from Securi-Guard

We always recommend the best ​security alarm system​ determined by your specific needs, with three main options available.

  • Audible Only Systems:​ Relies on noise and flashing lights to alert passers-by to call the police. Not linked to an ARC, this ​alarm system​ is more suitable for home owners.
  • Monitored Systems:​ Highly recommended for business and commercial customers, they are usually registered with the police via a Unique Reference Number and often have an audible delay to improve the chances of catching an intruder. If an alarm is activated, our ARC operators can notify the police.
