Office security alarm systems are often the first line of defence. These systems are designed to promptly detect intrusions and unauthorised movement, then alert people to the danger.

A typical alarm setup for an office includes door and window contact sensors (which trigger if opened unexpectedly), motion detectors inside rooms or hallways, and a control panel or keypad to arm/disarm the system.

Modern business alarm systems can do much more than just make noise; many are connected to 24/7 monitoring services or directly to the business owner’s phone. With professional monitoring, the moment an alarm goes off, a security team or call centre is notified.

Office building security systems extend the same principles used in a single office to a bigger scale and often integrate multiple technologies for complete coverage. In a multi-tenant or multi department building, you may need to protect common entrances, lobbies, corridors, parking areas, and each individual office unit.

This usually involves combining CCTV surveillance, intruder alarms, and access control across the whole premises in a coordinated way. Large office buildings often require multiple cameras to cover all entrances, hallways, and exterior perimeters. Office building access control might involve a secured main entrance (e.g. requiring a key card or visitor sign in at reception).
