Why Every Entry Point in Your Home Needs a Sensor

Most break-ins happen through doors and windows, the areas sensors are built to protect.

Over 60% of home break-ins happen through a door or window. Front doors, back doors, ground-floor windows, patio doors, and sliding doors are the most common entry points for intruders and the most important areas to monitor.

A standard lock can be forced, a window can be prised open, and a patio door can be bypassed. But a door and window sensor catches all of this the instant it happens. The moment protected entry point is opened, whether by force or by an unlocked latch, the alarm triggers and the response begins

At Brocus, we assess every entry point in your home and install sensors in the right locations to ensure nothing is left unprotected. Everything connects to your security panel and 24/7 monitoring from day one.

Key Features of
Door and Window Sensors

Professional-grade features that keep your home covered around the clock.

Triggers Home Alarm / Siren

The moment a protected door or window is opened unexpectedly while the system is armed, the alarm siren activates immediately, alerting everyone in the home and deterring intruders from going further.

Instant Mobile Alert

Alongside the alarm, a notification is sent directly to your smartphone the moment a sensor is triggered. You know which entry point was opened, and when in real time, wherever you are.

Connected to 24/7 Monitoring Center

Every trigger is reported simultaneously to the professional monitoring center. Trained specialists respond straight away and dispatch emergency services if needed. Without waiting for you to make the call.

Open / Close Status Visible in App

Check the real-time status of every door and window in your home from the mobile app. See at a glance which entry points are open or closed. Useful for everyday peace of mind, not just emergencies.

Works on All Door and Window Types

Sensors are compatible with standard doors and windows, as well as sliding doors, patio doors, and skylights so every entry point in your home can be covered, regardless of its style or design.

Tamper Alert if Sensor Is Removed or Damaged

If anyone attempts to remove, disable, or damage a sensor, you receive an immediate tamper alert on your phone. The system is designed to detect interference and respond to it just as it would to a triggered alarm.

Wireless, No Wiring Required

Sensors are fully wireless and attach easily to door and window frames without any drilling or complex installation. A technician handles full setup after your order is confirmed.

Battery Powered

Running on battery power, door and window sensors operate independently of your home's electricity supply. Low battery alerts are sent to your app in advance so replacements are never a surprise.

Integrates with Security Panel and App

All sensors connect to your home security control panel and mobile app, giving you a complete view of every entry point alongside your cameras, alarms, and other security devices. All from one place.

Where Door and Window Sensors
Make the Most Difference

Every opening in your home is a potential entry point, here's how sensors cover them all.

Front and Back Doors

The most commonly used entry points in any home are also the most targeted. Sensors on your front and back doors provide the first and most important line of defence against unauthorised entry.

Ground-Floor Windows

Ground-floor windows are one of the most common ways intruders enter a home, especially when left unlocked or slightly open. A sensor on each window ensures any unexpected opening triggers an immediate alert.

Patio and Sliding Doors

Patio and sliding doors are frequently targeted because they can be harder to secure with a standard lock. Sensors work on sliding doors and patio frames, closing off this common vulnerability.

Skylights and Roof Windows

Skylights are often overlooked in home security planning but they represent a real entry point. Sensors can be fitted to skylights and roof windows to ensure even these less obvious openings are covered.

How Door and Window Alarm Sensors Work

Small devices, instant response. Protecting every opening in your home.

While the system is armed, any unexpected separation triggers the alarm immediately

The alarm siren activates and an instant alert is sent to your smartphone

The 24/7 monitoring center is notified at the same time and responds straight away

Emergency services are dispatched if needed. Without you needing to make the call

Open and close events are logged in the app so you can review activity history at any time

A small sensor is fitted to the frame and a magnet is placed on the door or window it self, when the two are separated, the sensor detects an opening

When the system is disarmed such as when you're home during the day, doors and windows can be opened normally without triggering the alarm, while the open/close status continues to update in the app.
