Void Property Security Solutions

A void property carries risks that simply do not exist in an occupied one. Without regular activity, early warning signs go unnoticed — a small water leak develops into serious damage, indoor temperatures fall below freezing, intruders enter undetected, and even the early stages of a fire can go unreported for hours. The longer an empty property sits unoccupied, the greater the exposure to loss and structural damage.

What makes void property security different from standard alarm systems?

Conventional alarm systems are poorly suited to empty buildings. Most depend on a broadband connection, a landline, or continuous mains power — services that are often disconnected or entirely absent in a vacant property. Unlike conventional systems, Mobeye devices require no broadband, no landline, and no fixed wiring, making them suitable where utilities are unavailable or cut off.

The Mobeye range is designed specifically for these conditions. Each device is battery powered and communicates via the 4G mobile network, requiring no fixed wiring or on-site engineer — installation takes only minutes. The devices operate autonomously, continuing to monitor a void or vacant property even when utilities are unavailable. Battery life is typically over a year, depending on device type and trigger frequency, meaning extended protection without regular site visits.

When a sensor detects a problem, an alert is sent immediately through the Mobeye Messages app, by SMS, or directly to an Alarm Receiving Centre — ensuring property owners, landlords, and managers are informed the moment an issue arises.

Because the devices are portable, they can be moved between sites as properties change status, making them a practical choice for landlords, developers, and facilities managers responsible for multiple empty buildings.

What is a void property?

A void property is a building that is temporarily unoccupied — between tenants, undergoing refurbishment, awaiting sale, or standing empty before redevelopment. Void periods create specific risks that require dedicated monitoring rather than a standard burglar alarm.

Choosing the right protection

Every vacant property presents different risks. Effective monitoring begins with identifying the most likely threats.

  • Intruder detection indoors: The MiniPir iCM41 monitors internal movement and sends an immediate alert if someone enters the building.
  • Outdoor perimeter protection: The 4G Outdoor Alarm CMVXI-R provides intrusion detection for external areas, yards, and building perimeters.
  • Independent fire detection: The Smoke Detector CM4400 detects fire without the need for a wired fire alarm panel or active power supply.
  • Power failure monitoring: The PowerGuard CM4100 monitors mains electricity and sends an alert the moment power is lost — an early sign of tampering or a wider site problem.
  • Frost and temperature monitoring: The ThermoGuard CM4200 tracks indoor temperature and warns when levels approach freezing, protecting against burst pipes and structural frost damage.
  • Leak and flood detection: The Mobeye WaterGuard Detectors detect water ingress and flooding, helping prevent costly structural damage in unattended buildings.

These devices operate continuously and only require attention when an alert is triggered. Once an empty property is reoccupied, the same equipment can be reused or redeployed at another vacant building.

Where void property monitoring is used

Void property security systems are used across a wide range of situations:

  • Residential properties left unattended for extended periods
  • Commercial and industrial buildings between tenancies
  • Properties undergoing refurbishment or planned maintenance
  • Construction sites and new-build developments before permanent infrastructure is installed
  • Large commercial portfolios of vacant buildings managed by facilities teams

The same monitoring approach works equally for a single residential property and a portfolio of commercial buildings.

Frequently Asked Questions

Do I need a phone line or broadband connection to remotely monitor my property?
No. Mobeye devices connect via the 4G mobile network. A mobile signal at the property is sufficient — no landline or broadband connection is required.

How long do the batteries last?
Battery life is typically up to twelve months, depending on the device and how frequently sensors are triggered. Units are designed for extended operation without a site visit.

Can I monitor more than one property?
Yes. The Mobeye Messages app supports multiple devices across different properties from a single login, making it straightforward to manage an entire portfolio of vacant buildings.

Do insurers recognise monitored alarms for unoccupied properties?
Many UK insurers require a monitored alarm as a condition of void property cover. A Mobeye system may help satisfy those requirements — confirm the specific conditions with your insurer directly.
