Frequently Asked Questions

  • What's included in a typical commercial security system?

    Most commercial security systems are built around alarm monitoring, but what's actually included can look quite different from one business to the next. Depending on your premises, this might mean motion sensors, entry and exit alerts, or integration with other systems like access control. The right combination really comes down to your site layout, your industry and the specific risks you're trying to cover.

  • How do I know if my current security system is enough for my business?

    It's not always obvious that a system has fallen behind until something goes wrong. Things like the value of assets on-site, how much foot traffic you get, whether you've had incidents in the past, and any compliance requirements for your industry all play a part. Getting a site assessment is usually the easiest way to find out if there are gaps and whether an upgrade makes sense.

  • Can my business security system be professionally monitored?

    Yes, and for a lot of businesses, this ends up being one of the most valuable parts of the system. Professional monitoring means that if your alarm goes off, a monitoring centre is notified straight away, day or night, rather than relying on someone hearing the alarm or noticing something's wrong. It gives you a much faster response than the alarm working on its own.
