MK Security & Data
Mark and Haylee rescheduled for multiple customers facing urgent situations — flexibility that's rare in residential security.
The scheduling flexibility described across multiple reviews — rescheduling for a neighbour dispute situation, fast-tracking for a customer in need — points to an owner-operated business that makes individual calls rather than working from a fixed queue. The sample size is small relative to the 77 total reviews, so confirm current availability and lead times directly, as demand for a two-person outfit can shift quickly.

About MK Security & Data
Mark and Haylee run MK Security & Data as a hands-on duo — Mark handles the technical installation work and brings deep expertise in current security systems, while Haylee is actively involved in the customer-facing side and is specifically praised for communication from first contact through to job completion. The business focuses on residential security: CCTV camera systems and alarm installations for homes, with repeat customers confirming they return for both types of work rather than treating them as separate specialist jobs. What sets them apart from larger outfits is their willingness to flex scheduling around urgent situations — multiple customers describe them rescheduling or fast-tracking installs when a genuine need arose, something that's genuinely rare in a trade where multi-week waits are common. The workmanship is repeatedly described as meticulous and clean, which matters in a home environment where cabling and equipment placement has to be lived with for years. With roughly a decade of operation out of Byford, they serve the broader Perth metro area and appear particularly well-suited to homeowners who want a single trusted contact for both alarm and CCTV rather than juggling separate contractors.
Best for: homeowners replacing outdated CCTV or alarm systems, households needing both alarm and camera installation handled by the same team, and anyone who wants genuine post-install support rather than being left to figure out their system alone.

What areas does MK Security & Data service?+
MK Security & Data is based in Byford in Perth's south-eastern corridor. Reviews reference installations in North Coogee and surrounding suburbs, suggesting they travel across the broader Perth metro area. It's worth confirming your specific location when you reach out, as travel availability may vary depending on their current schedule.
Who actually does the work — is it owner-operated?+
Yes, Mark and Haylee run the business directly. Mark handles the physical installation and is praised in multiple reviews for meticulous, clean workmanship and up-to-date knowledge of current security equipment. Haylee is actively involved in customer communication and coordination. You're dealing with the owners throughout, not a rotating roster of subcontractors.
Can MK Security & Data handle both alarm systems and CCTV, or do they specialise in one?+
Reviews confirm they install both alarm systems and CCTV camera systems for residential properties. Multiple customers have used them for both types of work across the same or different properties. If you need both systems at once or want to upgrade one now and add the other later, they appear well-placed to handle that without you needing separate contractors.
What do customers say about their pricing?+
The small sample of reviews we analysed describes their rates as reasonable, and one customer specifically notes high-end equipment quality alongside affordable pricing. There are no detailed cost breakdowns in the available reviews, so get a quote directly to compare — but nothing in the feedback flags pricing as a concern.
How quickly can they get to a job?+
Turnaround time is a genuine strength mentioned across multiple reviews. Customers describe waiting only a few days rather than the weeks common in this trade, and at least two separate reviews describe Mark and Haylee rescheduling or bringing forward appointments when a customer's situation required faster action. That said, they're a small team, so lead times will depend on current demand — check availability when you contact them.
