Top 7 Security Companies in Perth for 2026

You're probably doing what most Perth buyers do at the start. Opening tabs, comparing websites that all say “quality service”, and trying to work out which security company will answer the phone, install neatly, and support the system after handover. That confusion is normal. Security buying in Perth isn't just about choosing a camera brand or an alarm app. It's about choosing the team that will design, install, maintain, and troubleshoot the system you'll rely on when something goes wrong.

That matters even more in a city the size of Perth. Greater Perth's resident population was estimated at about 2.16 million in June 2024, which helps explain why the local market covers everything from homes and strata complexes to warehouses, schools, offices, and industrial sites across the metro area and beyond, according to the Perth security market overview. In a market this broad, the right provider for a family home in Joondalup often isn't the right provider for a multi-tenant commercial site in Canning Vale.

This guide gets to the point. You'll find a practical shortlist of security companies in Perth, clear trade-offs between them, and buying guidance that helps you compare quotes properly instead of guessing from glossy marketing.

1. Securitec Security

Securitec Security is the strongest all-round pick here if you want a Perth specialist that can handle both straightforward residential jobs and more involved commercial or strata work without treating every site like a cookie-cutter install. The business is family-run, licensed, police-cleared, and focused on security technology rather than trying to be everything to everyone.

The practical advantage is breadth with accountability. Securitec handles planning, design, installation, repairs, and maintenance for CCTV, alarm systems, access control, and intercoms. That sounds standard on paper, but in the field it matters. Plenty of providers can install a system. Fewer are organised enough to return later, diagnose faults properly, and keep the whole setup reliable.

Securitec states it has over 30 years of local experience, with more than 5,621 properties protected and 4,207 satisfied clients on record. Those figures come from the company profile and should be read as social proof rather than a substitute for checking scope, service response, and fit for your site.

Where Securitec fits best

This is a good option for homeowners who want a clean, user-friendly system without ending up with overcomplicated hardware. It's also a strong fit for SMEs, strata, and industrial clients that need integrated systems across cameras, alarms, access control, and intercoms.

If you're comparing vendors, Securitec's residential and commercial security systems in Perth page gives a useful view of the range they cover.

Practical rule: The best installer for a home isn't always the best integrator for a warehouse or strata site. Ask who does the design, who does the commissioning, and who handles faults after handover.

Pros and trade-offs

• Best for end-to-end delivery: Securitec covers design, install, repair, and ongoing servicing, which reduces the handoff problems that happen when sales, installation, and support are split.
• Strong local fit: The company is Perth-focused, which usually means better familiarity with local site types, councils, trades, and service expectations.
• Broad project range: Homes, businesses, strata, and industrial sites all sit comfortably within its core offering.
• Main drawback: Pricing isn't published online, so you'll need a custom quote.
• Another limitation: If you need a national provider with interstate standardisation, a Perth-focused firm may not match that operating model.

For buyers who care about reliability more than marketing noise, this is the kind of provider worth speaking to early.

2. Castle Security

Castle Security stands out as a long-running WA family business with a broad electronic security offering. It covers CCTV, intruder alarms, access control, intercoms, and cloud-managed systems, and it also offers monitoring from its Landsdale base. If you want one supplier to unify several systems, Castle is an obvious name to include on your shortlist.

What I like about this type of provider is the full-stack approach. For a business with multiple doors, cameras, users, and maybe more than one site, fragmented systems become painful fast. Separate apps, separate service contacts, and no clear fault ownership usually lead to downtime and confusion.

Best use case

Castle makes sense for buyers who want integration more than bargain pricing. A retail group, office, warehouse, or school that needs CCTV tied to access control and remote management will usually get better long-term value from a provider that can build a unified platform.

If access permissions are a major part of your brief, it's also worth understanding how access control systems in Perth should be designed around user management, doors, audit trails, and future changes, not just hardware at the entry point.

If a provider can't explain how cameras, alarms, and door access will work together, they're selling components, not a system.

Pros and trade-offs

• Good integration capability: Better suited than many installers for combining multiple systems under one support model.
• Monitoring options: Useful if you want either self-monitoring or professional monitoring depending on risk and budget.
• Commercial strength: Cloud CCTV and cloud access control are especially relevant for multi-site operators.
• Main drawback: Pricing is quote-based.
• Watch-out: Lead times may stretch on larger commercial jobs, especially where design and staging are more involved.

Castle is a sensible choice when the brief is bigger than “install four cameras and leave”.

3. Crown Security

Crown Security leans more toward bespoke commercial and enterprise work than mainstream domestic installs. Based in Joondalup, it's better known for customized solutions involving CCTV, intrusion systems, access control, and systems integration. If your project needs analytics, custom workflows, or a less standard design, Crown deserves attention.

This is not the vendor I'd call first for a basic home package. It's the one I'd call when the site has operational complexity. Car parks, shared commercial spaces, higher-risk assets, or projects where video data needs to do more than just record footage all fall into that category.

Why some buyers will prefer Crown

The standout point is its analytics and integration angle. Many security companies in Perth can mount cameras and connect them to a recorder. Far fewer can turn video into something operationally useful.

For businesses thinking beyond passive surveillance, it helps to look at security systems monitoring as an ongoing operational function, not just a camera feed you check after an incident.

Pros and trade-offs

• Commercial focus: Better aligned to business, enterprise, and organisational projects than basic residential jobs.
• Analytics capability: A stronger fit when CCTV needs to support vehicle management, site rules, or workflow visibility.
• Custom design: Good when off-the-shelf packages won't suit the site.
• Main drawback: Public pricing and package detail are limited.
• Another trade-off: Buyers wanting a quick, simple, low-cost install may find Crown more complex than they require.

Crown is for projects where the design brief matters as much as the hardware list.

4. Securus

Securus is a solid option if monitoring quality is high on your priority list. The key differentiator is its ASIAL Grade A1 monitoring centre in WA, alongside supply, installation, servicing, managed monitoring, and response capability across home, commercial, industrial, and healthcare environments.

That local monitoring angle matters because many buyers still compare providers only on hardware. In practice, the response model often matters more than the camera model. A decent system with strong support and monitoring will usually outperform a technically impressive system that nobody actively manages.

Where Securus is strongest

Securus suits clients who want one company to supply the gear and remain involved after commissioning. It's also a practical fit for sites where verification, alarm handling, and remote oversight matter just as much as installation quality.

The broader Perth market is also moving in that direction. Independent local listings show buyers are already familiar with managed services and cyber-security support, with GoodFirms listing 34 cyber-security companies in Perth. That's relevant because modern CCTV, access control, and alarm systems increasingly sit on networked infrastructure and need secure remote support.

A modern security provider should be able to talk about firmware, remote access, network segregation, and incident response. If they can't, the system may be exposed even if the camera coverage is good.

Pros and trade-offs

• Monitoring-led value: Strong fit if you want local professional monitoring as part of the package.
• Broad sector coverage: Homes, industrial sites, and healthcare facilities all sit within its service range.
• End-to-end service: Better continuity than using separate installers and monitoring providers.
• Main drawback: Pricing isn't listed publicly.
• Watch-out: Product tiers and brand choices are typically discussed case by case, so ask detailed questions during quoting.

5. Smart Security

Smart Security takes a more flexible approach than most of the names on this list. It offers installed systems for CCTV, alarms, access control, and intercoms, but it also supplies DIY components. That split makes it appealing to homeowners and small business buyers who want more control over budget or already have some technical confidence.

This flexibility is useful, but it comes with a clear trade-off. DIY can save money upfront, yet it also shifts design, placement, commissioning, and fault-finding onto the customer. That's fine for some sites. It's a poor fit for properties where reliability is the whole point.

When Smart Security makes sense

If you're securing a standard home, small shop, or office and you want options rather than a fully managed integrator model, Smart Security is worth considering. It also offers personal and medical alarm products, which broadens its relevance beyond conventional intrusion protection.

A buyer who knows exactly what they want may appreciate that freedom. A buyer who doesn't may end up with mismatched devices, poor camera angles, weak Wi-Fi performance, or no clear support path.

Pros and trade-offs

• Flexible buying path: You can choose professional installation or supply-only, depending on budget and confidence.
• Good residential and SME fit: The offering feels more practical for straightforward sites than highly engineered projects.
• Broader safety range: Personal safety and medical alarm options may suit households with vulnerable occupants.
• Main drawback: DIY places more responsibility on the customer.
• Important caution: Monitoring, service inclusions, and post-install support should be clarified before you commit.

Cheap hardware is expensive when the app setup fails, remote access breaks, or the footage you need isn't usable. That's where professionally designed systems usually earn their keep.

6. Casa Security

Casa Security is a WA-owned provider with a long local presence, serving domestic, commercial, and government clients. It offers intruder alarms, CCTV, monitoring, and end-to-end service from design through to installation and ongoing support. For buyers who value local longevity, Casa has that established-market feel.

This kind of company often appeals to clients who want a known Perth operator rather than a flashy national sales machine. That's a reasonable instinct. Security is one of those services where stable local support often matters more than polished branding.

What to watch during quoting

Casa's website gives a decent sense of brands and solution areas, but buyers should ask for more detail on actual integration architecture. That's especially important for commercial and multi-user sites where cameras, alarms, and access control need to behave as one system rather than three separate products.

That issue matters across the wider industry. In Western Australia, buyers should verify licence class, installer credentials, and whether the work also requires electrical or data-communications capability under the state's licensing framework, as outlined in this WA security provider licensing discussion.

Pros and trade-offs

• Established local presence: Longevity is useful when you want confidence the provider understands Perth conditions and client types.
• Cross-sector experience: Domestic, commercial, and government work suggests range.
• End-to-end model: Design, install, and monitoring under one roof is generally a positive.
• Main drawback: Limited public detail on package pricing and service levels.
• Buyer tip: Request a clear system design, support scope, and maintenance terms in writing.

7. Tecsec Security Solutions

A clinic needs CCTV at the entry, a duress button at reception, controlled access to staff areas, and a PA system that ties into incident response. That is the kind of job where Tecsec Security Solutions makes more sense than a standard alarm installer.

Tecsec sits further up the integration chain than many Perth residential providers. Along with CCTV, monitored alarms, access control, and intercoms, it also handles duress, hold-up, door release, public-address, and AV or communications systems. For sites with front-of-house staff, public access, or higher duty-of-care requirements, that broader scope can reduce coordination problems and avoid the usual blame shifting between separate contractors.

The practical trade-off is straightforward. A basic home alarm and a few cameras do not usually need this level of design input. A school, medical practice, office with after-hours access, or mixed-use commercial site often does.

Best fit

Tecsec is worth shortlisting where security needs to work alongside communications and day-to-day site operations. One integrator taking responsibility for CCTV, entry control, duress, and related low-voltage systems usually produces a cleaner result than stitching together multiple vendors after the fact.

That matters more as buyers ask for systems that share events, recordings, alerts, and access rules across one setup rather than isolated devices. Analysts at Expert Market Research note continued growth in the sector in their Australia security market forecast. In practice, Perth buyers should read that as a reason to compare integration quality, service capability, and quoting clarity, not just hardware brands.

Pros and trade-offs

• Strong specialist scope: Good fit for duress, hold-up, PA, door release, and multi-system low-voltage work.
• Better for operational sites: Suits clinics, schools, offices, and commercial premises with staff-safety or access-management needs.
• Useful metro position: West Perth base should help with central and inner-metro service coverage.
• Main drawback: Quotes are project-based, so buyers need to pin down scope, programming, commissioning, and training line by line.
• Buyer tip: Ask who owns the system programming, what ongoing support includes, and whether future add-ons can be done without replacing the core platform.

Top 7 Security Companies in Perth, Comparison

Final Thoughts

A buyer in Perth usually reaches the same point fast. Two quotes can look similar on paper, both promise cameras, alarms, app access, and support, yet the long-term result can be very different. The gap usually shows up later, in false alarms, patchy remote access, slow fault response, or a system that never quite fits the site.

A practical short list should start with a few key questions. Is the provider licensed for the work being quoted? Do they install and service their own systems, or hand parts of the job to others? Can they explain how monitoring, firmware updates, remote access, data storage, and callout response work on your site, in plain language? Clear answers here usually matter more than a polished sales pitch.

Perth buyers also need to treat security as connected infrastructure, not just hardware. Many current systems rely on apps, IP networks, cloud services, and remote administration, which means the installer's approach to passwords, user permissions, firmware management, and router setup affects day-to-day reliability. As summarised in this Perth cyber and integrated security market snapshot, the local market now includes a visible mix of cyber-focused and integrated service providers. For homes this may be a smaller issue. For businesses, strata sites, medical practices, and warehouses, it often becomes part of the buying decision.

Pricing is where confusion usually starts.

Fixed prices are rare because good quoting depends on site conditions. Cable runs, switch capacity, recorder storage, access control hardware, intercom needs, after-hours access, and whether the job is a retrofit or a clean install all change the scope. A useful quote should break out hardware, labour, commissioning, training, warranty terms, and any ongoing maintenance or monitoring fees. If one quote is much cheaper, check what has been left out.

The better question is not "How much for four cameras?" It is "Who will maintain this system properly, and will it still suit the site in two years?" That question helps separate a workable buy from a system that becomes a recurring problem.

If you want a customised recommendation instead of another generic quote, Securitec Security is a strong place to start. They work across homes, businesses, strata, and industrial sites in Perth, and they handle the full process from design to installation, repairs, and ongoing servicing.
