Smart, scalable access control systems for offices, warehouses and multi-site operations. Designed, installed and supported by trusted commercial security specialists. Backed by 25+ years of experience and chosen by some of Australia’s most recognised brands.








From single-door offices to multi-site operations across Australia and New Zealand, we design access control systems around the specific needs of your business.
Staff-only zones, roller door control, contractor access, delivery management
Front-of-house, server rooms, executive areas, after-hours access
Back-of-house, stockroom, multi-location staff management
Restricted plant areas, hazardous zones, contractor compliance
Drug storage, restricted clinical areas, audit trail for compliance
Lift access, car park entry, common areas, resident management
Mechanical keys cost businesses far more than most realise. Here are the most common reasons our commercial clients move to a modern access control system, or upgrade an outdated one.
A single lost master key can cost thousands in re-keying every lock in the building. Electronic credentials are simply deactivated and reissued in seconds.
When a staff member or contractor leaves, mechanical keys are rarely returned. Electronic access is revoked instantly, including remotely if needed.
Mechanical locks give you no audit trail. Modern access control logs every entry, exit, and denied attempt for compliance, investigations, and HR.
Operating across multiple sites? Cloud-based access control gives you a single dashboard to manage every door, every user, every site, from anywhere.
Some areas need to stay restricted: server rooms, drug storage, stockrooms, executive areas. Access control lets you grant access by person, by time, by area.
Need to let a cleaner in at 6am, or a contractor on a Saturday? Time-based access permissions let you grant exactly the access needed, exactly when needed, without handing out keys.
We design every access control system around the layout of your site, the way your team works, and how you want to manage access day-to-day. Whether you need to lock down a single back-of-house door or manage thousands of users across multiple sites, our systems are built to scale with your business.

OUR 5-STEP COMMERCIAL ACCESS CONTROL PROCESS
No two commercial sites are alike. Our process is built around understanding your operations, designing a system that fits, and delivering it with minimal disruption to your business. From your first call through to ongoing support, here’s exactly how it works.

Call us on 1300 73 83 93 or submit an online enquiry. We respond within one business day to discuss your site, your security concerns, and the outcomes you need.
For most projects, this short conversation is enough to confirm scope and book the next step.
Timeframe: Response within 1 business day
A licensed security specialist reviews your site, identifies vulnerabilities, considers any existing infrastructure, and confirms exactly what’s required. Most assessments are conducted on-site so we can walk the premises with you and plan around the realities of your space, including cabling routes, after-hours access, and integration with existing systems. Where appropriate, particularly for standard product installs or sites outside Melbourne, we can also complete this stage remotely.
For access control projects, we assess door schedules, user groups and permissions, credential type (cards, fobs, biometric or mobile), and integration requirements with your CCTV, intercom, or HR system.
Timeframe: Booked within 3 to 5 business days of your enquiry
We design the system around your site, your operations, and your budget. You receive a written proposal showing equipment specifications, placement, integration points, project timeline, and a fixed price. Because commercial systems are rarely off-the-shelf, we take the time to get the design right, no surprise costs after the fact.
For access control, your proposal includes door controller layout, reader placement, user and group permissions, audit log requirements, and multi-site management capability if you operate across multiple locations.
Timeframe: Tailored to project complexity. We’ll confirm a clear delivery date during your site assessment.
Our licensed technicians install the system at a time that suits your operations, including after-hours or weekend installs where required to avoid disrupting your business. On completion, we hand over as-built documentation, user credentials, and training for nominated staff, so your team can use the system confidently from day one.
For access control installs, this includes mounting readers, fitting electric or magnetic locks, controller commissioning, credential enrolment for your staff, and admin training on adding, removing, and managing users yourself.
Timeframe: Scheduled at your earliest convenience after quote approval
A security system is only as reliable as its maintenance. We keep full records of your installed equipment, offer lifetime phone support, and provide optional maintenance programs to keep your system performing to Australian Standards.
When a technician is required on site, you’ll have someone already familiar with your exact setup.
Timeframe: Lifetime phone support, with optional 24/7 monitoring available.

Phil arrived well ahead of schedule and did a fantastic job. He was very knowledgeable and friendly and efficient. Would like to thank him for a job well donePosted on Google John Tame26/02/2025Trustindex verifies that the original source of the review is Google. The service fella arrived on time, introduced himself and his apprentice, then got on with the job. Serviced our system, cleaned the smoke alarm and all was good. As we signed yo to a 60 month agreement, there was no charge for the service call and there wont be for the next 5 years. We have always been very happy with the service and if there was a reason for the to think there was a problem at our house, they were always quickly on the ball
A simple single-door install can be completed in a day. Larger multi-door or multi-site projects are typically completed within 2 to 5 days, scheduled in stages to avoid disrupting your operations. We’ll confirm the exact timeline in your quote.
We support the full range: RFID cards and fobs, PIN codes, mobile credentials (phone-based access), and biometric readers including fingerprint and facial recognition. Most businesses use a mix depending on the security level of each area. We’ll recommend the right combination during your site assessment.
Yes. Modern cloud-based platforms let nominated admins manage every door, every user, every site, from a single dashboard, on desktop or mobile. Add a new starter on Monday, revoke access on Friday, lock down a specific door instantly, all without calling a technician.
Yes. Cloud-based access control platforms can integrate with most modern HR systems and identity providers (Microsoft Entra ID, Google Workspace, BambooHR and similar) so new starters are automatically provisioned with the right access on day one, and departing staff are deactivated automatically on their last day. We’ll confirm specific integration options during your site assessment.
Yes, and we’d recommend it. Integration gives you a single source of truth: a card swipe at a door triggers a camera recording, an alarm activation can automatically lock specific doors. We work with all major commercial platforms and will confirm integration capability during your site assessment.
Every system we install logs every entry, exit, and denied attempt against the user and credential used. Reports can be generated for compliance audits, HR investigations, or facility management. Some industries (healthcare, finance, government, ISO 27001 certified businesses) have specific audit requirements, which we’ll factor into the system design.
Most office and warehouse changeovers happen with minimal disruption. We install hardware out of hours where required, enrol staff credentials in batches, and run a short orientation so your team knows how to use the new system from day one. Mechanical keys can be kept as emergency override if needed.
All commercial access control systems we install include backup power, so doors continue to operate during outages. We also configure fail-safe and fail-secure settings per door based on its role: fire-rated egress doors fail open for life safety, while server room doors typically fail secure.
Signal Security supports commercial clients across Australia and New Zealand, from single-site businesses to multi-site enterprise operations. Whether you’re a single location or operating across multiple states or both sides of the Tasman, get in touch and we’ll discuss how we can support your sites.
Costs depend on the platform you choose. Cloud-based platforms typically include a subscription fee per door or user, which covers remote management, automatic software updates, and multi-site visibility. On-premise systems have no subscription but require more hands-on administration. Most commercial clients also choose a maintenance program for priority support. We’ll outline all ongoing costs clearly in your quote so you can choose what suits your business.
