Vibration Sensors

Vibration sensors are designed to detect impact, shock or vibration on a protected surface. Instead of waiting for a door or window to fully open, these sensors can help detect attempted forced entry earlier, such as someone striking, levering, drilling or tampering with a door, window, cabinet or glass panel.

Browse vibration sensors and shock detectors from trusted alarm brands. Always check compatibility with your alarm panel, wireless hub or receiver before purchasing.

Vibration sensors are commonly used where early detection of impact or tampering is important. They can add another layer of protection to areas that may be vulnerable to forced entry.

• Windows and glass entry points
• Front doors, rear doors and side doors
• Garage doors and roller doors
• Shopfronts and commercial premises
• Cabinets and storage areas
• Sheds and external access points
• High-risk entry points
• Selected safes, walls or protected surfaces

Shock detectors can help provide earlier warning of a break-in attempt by detecting impact or vibration before an intruder fully enters the property. They are often used alongside reed switches, motion detectors and break glass sensors for layered alarm protection.

• Detects vibration, impact and attempted forced entry
• Helps provide earlier warning before full entry occurs
• Suitable for residential and commercial alarm systems
• Available in wired and wireless options
• Compatible with selected Hikvision, Bosch and DSC alarm systems
• Useful for windows, doors, garage doors and commercial shopfronts
• Supports layered security when used with reed switches and motion detectors
• Helps protect vulnerable entry points where forced entry is a risk

The terms vibration sensor, shock detector and seismic detector are sometimes used across similar product categories, but the best choice depends on what you are protecting. Vibration sensors and shock detectors are commonly used on doors, windows and building entry points, while seismic detectors are often associated with higher-risk surfaces, safes, walls, cabinets or specialised security applications.

What does a vibration sensor do?
A vibration sensor detects impact, vibration or tampering on a protected surface and can trigger a compatible alarm system when forced-entry activity is detected.

Are vibration sensors the same as shock detectors?
The terms are often used together. Shock detectors are commonly used to describe sensors that detect impact or forced-entry attempts on doors, windows and panels.

What is a seismic detector?
A seismic detector is a specialised sensor designed to detect vibration or attack on high-risk surfaces such as safes, cabinets, walls or protected structures, depending on the model.

Where should vibration sensors be installed?
They are commonly installed on windows, doors, garage doors, shopfronts, cabinets and other vulnerable entry points.

Do vibration sensors replace reed switches?
Not always. Reed switches detect when a door or window opens, while vibration sensors detect impact or forced-entry attempts. Many alarm systems use both for layered protection.
