Vacant Property Security for Developers – Melbourne
In Melbourne’s fast-paced real estate market, vacant buildings and development sites are a frequent sight as projects await approval, construction, or sale. But even a brief vacancy can expose developers and investors to major risks that go far beyond inconvenience.
The Hidden Risks of Vacant Property in Melbourne
Vacant properties attract vandals, metal thieves, and trespassers. Damage to interiors, copper wiring, and air conditioning units can cost owners thousands.

Why Traditional Security Measures Often Fail
The Limits of Traditional Security for Vacant Sites
Patrols only visit on schedule, leaving long gaps where break-ins or theft can go undetected for hours.
Cameras often just record incidents but can’t stop them. Without 24/7 monitoring, footage is only evidence after the fact.
Old wired alarms can be disabled or cause too many false alarms, making staff less alert to real threats.
Physical security guards and patrols become expensive for large or multi-site properties over time.
To truly safeguard vacant properties in Melbourne, developers and owners need more than just traditional measures. Ajax offers a smart, reliable, and affordable solution — deterring intruders and delivering real-time alerts the moment a threat arises.

Ajax for Multi-Site Developer Portfolios
Managing security across multiple vacant properties simultaneously is one of the biggest operational challenges for Melbourne developers. Ajax solves this with a single unified platform that scales effortlessly from one site to dozens.
- One app, every site: Monitor all your Melbourne properties from a single Ajax account — arm, disarm, and review event logs without switching between systems.
- Rapid redeployment: When a site sells or construction begins, the wireless system is removed and reinstalled at the next vacant property in under an hour.
- Scalable user access: Grant site managers, contractors, or agents time-limited access to individual properties without compromising your master account.
- Consolidated reporting: Full event history per site for insurance documentation, due diligence, and investor reporting.
View live status, battery levels, and recent events for every site in your portfolio from one screen — desktop or mobile.
Assign different permission levels to project managers, real estate agents, and contractors — each with their own PIN or key fob.
Ajax devices pair to a new hub in minutes. Move your security investment from a settled property to the next vacant site without purchasing new hardware.
Every arm, disarm, alert, and access event is logged with a timestamp — providing the documented security history insurers and solicitors require.
How Ajax Handles Power Outages at Vacant Properties
A vacant property has no one on-site to notice when the power goes out. Ajax is engineered specifically for this scenario — with three independent layers of resilience that keep your security active regardless of what happens to the mains supply.
Built-In Backup Battery
Every Ajax hub contains an internal backup battery that activates the instant mains power is lost. The system continues operating normally — detecting, alerting, and communicating — without any interruption or manual intervention.
4G Cellular Failover
Ajax hubs operate on dual communication paths — Ethernet and 4G simultaneously. If the internet connection drops alongside the power, the system automatically switches to the 4G cellular network, maintaining the live link to your phone and the monitoring centre.
Wireless Sensors — No Mains Required
All Ajax detectors, door contacts, and sirens run entirely on long-life batteries. There are no wired sensor runs that depend on the building’s power supply, so a complete mains failure has zero effect on detection coverage across the property.
What Happens During a Power Outage — Step by Step
- ✓ Mains power is lost at the vacant property — Ajax hub switches to internal backup battery instantly, with no gap in coverage.
- ✓ If the NBN or router also loses power, the hub’s 4G SIM takes over all communications automatically.
- ✓ You receive a push notification on your phone alerting you to the power loss event — so you know immediately.
- ✓ All motion sensors, door contacts, and glass break detectors continue operating on their own batteries, unaffected.
- ✓ The monitoring centre remains connected via 4G and can dispatch a response if any intrusion is detected during the outage.
- ✓ When mains power is restored, the hub automatically reverts to primary communication paths and logs the full outage event with timestamps.
Protecting Heritage & Period Buildings in Melbourne
Melbourne’s heritage-listed and period buildings present a unique security challenge. Planning permits, heritage overlays, and strict conservation guidelines often prohibit drilling, cable runs, or any modification to original fabric — making traditional wired alarm systems completely unsuitable. Ajax solves this without compromise.
- Zero drilling required: Ajax devices mount with adhesive pads or minimal surface fixings — no penetrations through original plasterwork, timber, or masonry.
- No cable runs: Fully wireless communication between every device means no chasing cables through heritage walls or ceilings.
- Fully reversible: Every Ajax device can be removed cleanly, leaving the building fabric exactly as found — critical for heritage compliance and resale.
- Discreet form factor: Compact white devices blend into period interiors without the visual intrusion of bulky wired hardware or conduit.
- Council & permit friendly: Wireless installation typically falls outside the scope of works requiring a heritage permit, simplifying the approval process for developers.
Ajax wireless installation avoids the structural interventions that trigger heritage overlay permit requirements under Melbourne’s planning scheme — keeping your project on schedule.
Ajax sensors include built-in tamper detection that triggers an alert if a device is removed or repositioned — providing physical security accountability without any permanent fixings.
Period buildings often feature large original sash windows and leadlight glass. Ajax glass break detectors protect these irreplaceable elements without any contact with the glazing itself.
A full Ajax system can be installed in a heritage building in under two hours and removed just as quickly when the property sells or development commences — with zero trace left behind.
Full event logs and professional installation certificates satisfy heritage property insurers who require evidence of active, monitored security as a condition of cover.
Ajax Integration with Real Estate Agents & Property Managers
Vacant properties need regular access — for inspections, valuations, contractor visits, and open homes. Ajax makes this seamless without ever compromising the owner’s security or handing over master credentials.
Granular User Permissions
Add agents and property managers as secondary users with precisely defined access rights. They can arm and disarm the system for their visits without seeing event history, modifying settings, or accessing other properties in your portfolio.
Key Fob & Keypad Access
Issue individual Ajax Space Control key fobs or unique keypad codes to agents. Each fob or code is logged independently — so you always know exactly who disarmed the system, at what time, and for how long the property was unsecured.
Time-Limited Access Windows
Set access permissions to be active only during specific hours or date ranges — for example, Saturday 10am–12pm for an open home. Outside those windows, the agent’s credentials are automatically inactive and the system remains fully armed.
Instant Owner Notifications
Every arm and disarm event triggers a push notification to the property owner. You are immediately informed when an agent enters, how long they stayed, and when the system was re-armed — all without needing to call anyone.
The property owner can arm the system remotely via the Ajax app the moment an inspection ends — even if the agent forgets. No more relying on a third party to secure your vacant asset after every visit.
Issue temporary codes to plumbers, electricians, or cleaners attending the property. Codes expire automatically after the job window, eliminating the risk of unauthorised re-entry using old credentials.
Every entry and exit is timestamped and stored in the Ajax event log. This provides a complete, verifiable record of who accessed the property — valuable for insurance claims, disputes, and due diligence.
Agents and managers never need the master account credentials. Each user operates within their own permission boundary, keeping the owner in full control of the system at all times.
When a listing changes agents or a contractor’s job is complete, access is revoked from the app in seconds — no need to change locks, collect keys, or visit the property.
Agent Notifies Owner
Agent confirms inspection time via phone or email.
Owner Activates Access
Owner enables the agent’s key fob or code for the inspection window via the Ajax app.
Agent Disarms on Arrival
Agent uses their fob or code to disarm. Owner receives an instant push notification.
System Re-Armed Remotely
Owner re-arms the property via the app the moment the inspection ends — from anywhere.
