Driveways, garages and sheds are often overlooked when planning a home security system. Many homeowners focus on the front door and internal rooms, but outdoor areas, garages and detached sheds can be common targets for theft, attempted entry and after-hours activity.
The best security setup for these areas usually combines perimeter protection, outdoor detection, reed switches, sirens, app alerts and, where required, CCTV or monitoring. The right design depends on the property layout, whether the garage or shed is attached, and how the area is used day to day.
In this guide, we explain how to protect driveways, garages and sheds using alarm detectors and brackets, outdoor motion detectors and reed switches.
Why Driveways, Garages and Sheds Need Security
Garages and sheds often contain valuable items such as tools, bikes, garden equipment, sporting gear, ladders, machinery, work materials and sometimes vehicles. Driveways also provide access to cars, garages, side gates and external entry points.
These areas are important because they may:
- Be less visible from inside the home
- Have tools or equipment that are easy to remove
- Contain access points into the house
- Be detached from the main building
- Have roller doors, side doors or windows that need protection
- Be used by trades, family members, tenants or staff
- Have limited lighting or blind spots after dark
A well-designed alarm setup helps detect entry attempts earlier and provides better awareness around these vulnerable areas.
Best Security Setup: Quick Overview
| Area | Recommended Devices | Why It Works |
|---|---|---|
| Driveway | Outdoor motion detector, CCTV, lighting and app alerts where supported | Helps detect movement around vehicles, gates and entry paths. |
| Garage | Roller door reed switch, internal motion detector, siren and keypad/app control | Protects the main access point and detects movement inside the garage. |
| Shed | Door reed switch, wireless detector or outdoor-rated detector, siren and camera where practical | Provides protection for detached storage areas and valuable equipment. |
Security for Driveways
Driveways are important because they are often the first point of approach to the property. A driveway may lead to a garage, side gate, carport, front door, shed or backyard access point.
Good driveway security may include:
- Outdoor motion detection
- Security lighting
- CCTV coverage
- Alarm alerts for after-hours movement
- Gate or garage door contacts where suitable
- Clear visibility from the street or house
Outdoor Motion Detectors for Driveways
An outdoor motion detector can help detect movement around driveways, side paths, garages and perimeter areas. These detectors are designed for external environments and should be positioned carefully to reduce nuisance alarms from pets, passing cars, trees, shadows or weather movement.
Outdoor detectors are useful for:
- Driveway approaches
- Side access paths
- Garage fronts
- Carports
- Backyard access points
- External storage areas

Security for Garages
Garages are one of the most important areas to protect, especially if they have internal access into the house. They may contain cars, tools, bikes, storage, gym equipment, work gear and entry points into the home.
A strong garage security setup may include:
- Heavy-duty reed switch on the roller door
- Reed switch on the internal access door
- Motion detector inside the garage
- Internal siren or screamer
- External siren and strobe
- Smartphone app alerts where supported
- CCTV coverage of the driveway or garage entrance
Reed Switches for Garage Doors
Reed switches are ideal for detecting when a garage door, internal access door or roller door opens. For roller doors, a heavy-duty reed switch is usually more suitable than a standard door contact because the door is larger and the environment may be more demanding.
Reed switches can be used on:
- Garage roller doors
- Internal access doors
- Side garage doors
- Garage windows
- Pedestrian doors
- Detached garage entries

Motion Detectors for Garages
A motion detector inside the garage can provide a second layer of protection if someone gains entry. This is useful for garages that store valuables or connect directly to the house.
Garage detectors should be positioned carefully because garages can be affected by heat, insects, drafts, pets and moving objects. Professional placement helps reduce false alarms and improves detection coverage.
Security for Sheds
Sheds are often detached from the main house, which can make them more vulnerable. They may contain valuable tools, gardening equipment, ladders, bikes, power tools, machinery, pool equipment or work materials.
A shed security setup may include:
- Reed switch on the shed door
- Reed switch on shed windows where suitable
- Motion detector inside the shed
- Outdoor detector covering the approach
- Wireless alarm device where cabling is difficult
- Battery-powered or compatible wireless options where supported
- CCTV coverage if the shed is in a high-risk area
- Strong physical locks and door hardware
Detached Sheds vs Attached Garages
Detached sheds can be harder to cable than attached garages. If running alarm cable is practical, wired devices may provide long-term reliability. If cabling is difficult, wireless alarm devices may be considered where compatible with the alarm system.
| Structure | Security Consideration | Recommended Setup |
|---|---|---|
| Attached Garage | May provide direct access into the home. | Roller door reed switch, internal access door contact and garage motion detector. |
| Detached Garage | May need separate cabling, wireless devices or external detection. | Door contacts, internal detector, siren and outdoor detector on approach. |
| Garden Shed | Often stores tools and equipment but may have limited power or cabling access. | Reed switch, wireless detector where compatible, outdoor lighting and camera coverage where practical. |
Reed Switches vs Outdoor Detectors
Reed switches and outdoor detectors do different jobs. A reed switch protects a specific opening, while an outdoor detector monitors movement in an external area.
| Device | What It Detects | Best Used For |
|---|---|---|
| Reed Switch | A door, window, gate or roller door opening | Garage doors, shed doors, internal access doors and windows. |
| Outdoor Motion Detector | Movement in an external detection area | Driveways, side paths, yards, garage fronts and perimeter areas. |
For the best result, use both where suitable. A reed switch can detect when the garage or shed door opens, while an outdoor detector can detect movement before someone reaches the door.
Outdoor Detection and False Alarm Prevention
Outdoor detectors can be very useful, but placement is important. External areas are exposed to weather, animals, shadows, moving branches, passing vehicles and changing light conditions.
To reduce false alarms, outdoor detectors should be:
- Installed at the correct height
- Aimed away from roads and footpaths where possible
- Positioned away from moving trees or shrubs
- Selected for the environment they are protecting
- Mounted securely using suitable brackets
- Tested during day and night conditions
- Programmed correctly into the alarm system
Detector brackets can help improve the final result by allowing better angle adjustment, cleaner cable entry and more flexible mounting in difficult areas.

Wired vs Wireless Devices for Garages and Sheds
The best choice depends on whether cabling is practical. Attached garages are often easier to cable than detached sheds. Detached structures may need wireless devices, underground cabling, local power, or a different alarm design depending on distance and layout.
Wired Devices
Wired detectors and reed switches are a strong option where cabling can be installed neatly. They are often preferred for attached garages, renovations, new builds and permanent installations.
Wired devices are useful for:
- Attached garages
- New builds
- Renovations
- Commercial garages
- Warehouses and roller doors
- Long-term reliable installations
Wireless Devices
Wireless devices can be useful where running cable is difficult. They may suit detached sheds, finished garages, rental properties or locations where only one or two additional sensors are needed.
Wireless devices should be selected carefully because they depend on compatibility, signal strength and battery maintenance.
Should You Add CCTV?
Alarm sensors detect events, while CCTV provides visual information. For driveways, garages and sheds, CCTV can be useful because it helps you see what caused an alert and review activity after an event.
CCTV is useful for:
- Driveways and parked vehicles
- Garage doors
- Side paths
- Shed entrances
- Tool storage areas
- Delivery or visitor activity
- After-hours movement
For higher-risk properties, combining alarm sensors with CCTV verification can provide stronger awareness and better incident review.
Should You Add Alarm Monitoring?
Alarm monitoring may be worth considering if the garage or shed contains valuable equipment, if the property is often unattended, or if you may not always respond to app alerts.
Monitoring can be useful for:
- Holiday homes
- Investment properties
- Detached garages
- Workshops
- Commercial sheds
- Tool storage areas
- Businesses with after-hours risk
A monitored alarm can follow nominated response instructions when the system activates, rather than relying only on a siren.
