Prime Security Systems
Michael has repaired 20-to-35-year-old alarm systems that other technicians would have written off.
That combination is rare enough that multiple reviewers specifically mention it as what won their loyalty. The business is GST-registered, has been operating for roughly 23 years, and recent reviews in the sample are averaging higher than earlier ones, suggesting the service quality has held or improved. One reviewer raised a concern about not receiving a follow-up quote after an on-site visit, and one cited a high quote for a four-camera system — these are isolated mentions in a sample of 50, not a pattern, but worth raising pricing expectations and quote timelines directly when you make first contact.

About Prime Security Systems
Michael Gekas is the face and technician behind Prime Security Systems, with reviewers spanning more than two decades crediting him by name for everything from new alarm and CCTV installations to late-night emergency callouts and phone-based troubleshooting. What sets the operation apart is its willingness to work with aged systems — multiple customers note Michael diagnosed and repaired 20-to-35-year-old panels rather than pushing replacements, and one review describes him talking a homeowner through a full reset over the phone before attending in person days later. For new installations, he covers both residential and commercial properties, offering systems that don't require ongoing app-subscription fees — a detail customers specifically flag as unusual. His post-installation tuition is a recurring thread: reviewers mention him re-explaining controls until they were confident, setting up smartphone monitoring apps, and returning calls on day two to confirm everything was understood. Same-day and after-hours attendance is documented across multiple reviews, including a 4am alarm emergency and an evening visit on a hot day — making him a practical choice for urgent security problems rather than just planned upgrades.
Best for: same-day or after-hours alarm emergencies, diagnosing and repairing older or unfamiliar security systems, and new alarm or CCTV installations where hands-on tuition after setup matters.

Does Prime Security Systems handle after-hours or emergency callouts?+
Yes — multiple reviews document evening visits, a 4am emergency response, and weekend attendance. Michael has attended on the same day as the initial call in numerous documented cases, including a settlement-day battery failure and a system beeping through the night. If you have an urgent fault, it's worth calling directly rather than emailing to gauge availability. Reviews suggest he will often come out even outside standard business hours when the situation warrants it.
Can Prime Security repair my old alarm system, or will they push me to replace it?+
Repairing rather than replacing is a notable pattern across the reviews. Customers with systems ranging from 20 to 35 years old report that Michael diagnosed and fixed their panels without recommending unnecessary upgrades. In one case he talked a homeowner through a phone-based reset for a 20-year-old system and then organised new remotes. If your system is genuinely beyond repair, reviewers say he will explain options without pressure — one customer noted he offered upgrade options with 'zero pressure to purchase.'
What areas does Prime Security Systems service?+
The business is based in Brighton, SA, and multiple reviews reference residential and commercial jobs across the Adelaide metro area. Reviews mention customers in multi-storey units, standalone homes, and business premises. The data doesn't specify exact suburb boundaries, so if you're in an outer suburb it's worth confirming coverage when you call.
What do customers say about pricing at Prime Security Systems?+
Most reviews don't detail specific pricing, but several customers positively note that systems are offered without ongoing app-subscription fees — flagged as unusual compared to alternatives. One reviewer cited a quote of $4,000 for a four-camera system as high, though this is a single mention in 50 reviews and the business disputed the account. To avoid any ambiguity, it's worth asking Michael to confirm the quote in writing after an on-site assessment, as one reviewer noted a quote was not followed up after an initial visit.
Does Michael explain how to use the system after installation?+
Post-installation tuition is one of the most frequently praised aspects of the service. Reviewers across many reviews describe Michael walking them through system operation, setting up smartphone monitoring apps like DMSS, explaining day and night modes, and re-explaining features until customers felt confident. One reviewer specifically praised him for taking the time to make sure they understood before leaving. This appears to be a standard part of how jobs are completed, not an add-on.
