Imperial Security & Fire
Owner Brett visits every job in person before quoting — and one researcher found his prices well below most competitors.
That's a specific data point worth weighing if you've received quotes elsewhere and found pricing confusing or inconsistent. Frank the technician draws repeat mention for tackling work that other operators might decline, particularly on older or unusual equipment. The sample is too small to draw firm conclusions about response times or how the business handles problems post-install, so it's worth asking Brett directly about callout availability and what happens if a system needs attention after the job is done.

About Imperial Security & Fire
Brett Cavanagh, the owner of Imperial Security & Fire, stands out for doing something many security companies skip: visiting in person before quoting, so the scope of work and pricing reflects the actual job rather than a ballpark figure. Frank is the technician named in reviews, praised specifically for patience and problem-solving on unusual hardware — including recalibrating a retail security tag sensor so old that Frank had no prior experience with the model, yet got it working. The business handles both alarm systems and CCTV installations for residential properties, with reviews noting that older or legacy systems are within their wheelhouse rather than something they'd turn away. On pricing, one reviewer who contacted multiple competitors and conducted independent product research found Imperial noticeably more competitive — not marginally, but by a gap they described as hard to comprehend. Brett is also noted for being genuinely open to customer-requested changes during installation, which matters for homeowners who want a system configured to their specific layout rather than a standard package. With roughly 22 years in operation and GST registration as a company, this is a structured business rather than a sole trader, which affects things like warranty accountability and the ability to service what they install long-term.
Best for: residential alarm and CCTV installations where you want an in-person quote, homeowners with older or legacy security systems that need servicing or upgrading, and customers who've found other security company quotes inconsistent or overpriced.

Does Brett from Imperial Security visit in person before providing a quote?+
Yes — multiple reviewers specifically mention Brett coming to the property before quoting, which allows him to assess the actual installation requirements rather than giving a generic estimate. One reviewer who compared many security companies noted that Brett's approach was to properly understand the job and that his quote was both accurate and open to specific changes the customer requested. If you want a tailored quote rather than a package price, calling to arrange a site visit appears to be the standard process.
Can Imperial Security & Fire service or repair older security systems?+
Based on the reviews available, yes — the business has serviced older pre-existing alarm systems and upgraded sensors and equipment on legacy setups. Technician Frank is specifically mentioned for successfully recalibrating a very old retail security tag sensor that he had no prior experience with, suggesting a willingness to tackle unusual or niche hardware. If you have an older system from another provider, it's worth calling to describe what you have before assuming they won't take the job.
What do customers say about Imperial Security's pricing compared to competitors?+
One reviewer — who described themselves as a consumer product tester who contacted many security companies and conducted considerable research — found Imperial's pricing noticeably lower than most competitors for the same or similar product. They noted the difference was significant enough to be hard to comprehend. This is a single reviewer's experience from the 5 reviews we analysed, so confirm pricing directly, but it's a specific data point if you're comparing quotes.
Does Imperial Security & Fire install CCTV for residential homes?+
Yes — at least one reviewer had a standalone CCTV system installed for their house, with coverage focused on the front of the property. That reviewer noted the system had continued running at the same quality for years, and that updates from Imperial were quick when needed. The business is based in Sutherland, NSW, so confirm their service area covers your suburb before booking.
Who carries out the installations — the owner or a separate technician?+
Reviews suggest Brett Cavanagh (the owner) handles the quoting and client relationship side, while Frank is named as a technician who carries out on-site work. Frank is described as friendly, knowledgeable, and patient — particularly when dealing with complicated or unfamiliar equipment. The business operates as a company rather than a sole trader, so there appears to be at least a small team rather than a single-person operation.
