Electronic Security Technologies
Nathan personally handles assessments, installs, and post-job questions — customers with 15-year relationships keep coming back for upgrades.
That said, what those reviews point to is specific: Nathan is named directly across multiple reviews as the person who runs assessments, manages installs, and fields post-job questions, which means accountability sits with one identifiable individual rather than an anonymous team. Customers with long relationships (one mentions 15 years) keep returning for upgrades rather than switching, which is a meaningful signal when the review volume is too small to rely on averages alone. If you're considering them, ask Nathan specifically how he handles after-hours support and whether he services your suburb — the reviews don't cover those details and they're worth confirming directly.

About Electronic Security Technologies
Nathan leads EST with a hands-on approach that goes well beyond installing equipment — multiple customers describe a consultative process where he takes time to assess the specific premises before recommending any solution, which is uncommon in a category where many operators quote from a standard product list. His install crew is praised for working around active businesses and offices without disrupting daily operations, and Nathan personally walks clients through the new system at handover so they can manage it themselves without relying on a call-out. The business appears to serve both commercial clients (office fit-outs, business security assessments) and long-term residential customers, with one reviewer referencing a 15-year relationship and recent CCTV upgrade work. Post-installation support stands out in the reviews — Nathan fields technical questions in plain language rather than deflecting, which matters for homeowners who aren't tech-confident. EST is GST-registered and has been operating for roughly 13 years, suggesting a stable business rather than a newer operator still finding its footing. Based on review evidence, they're particularly well-suited to clients who want a security partner they can call back, not just a one-time installer.
Best for: commercial offices requiring a consultative security assessment, homeowners wanting a straightforward CCTV upgrade with proper handover training, and clients who value a long-term point of contact for ongoing support and system changes.

What areas does Electronic Security Technologies service?+
EST is based in Boolaroo, NSW, which places them in the Lake Macquarie region. Reviews reference jobs in that broader area, including a mention of work at Parkway Ave. The reviews don't specify how far they travel for jobs, so if you're outside the immediate Lake Macquarie area, it's worth calling Nathan directly to confirm whether they cover your location before requesting a quote.
Does EST work on commercial properties as well as homes?+
Yes — reviews explicitly describe commercial fit-outs including office environments where the install crew worked around an active business without disrupting operations. Nathan conducted a formal site assessment for that client before recommending a system, which suggests they're comfortable scoping larger or more complex commercial jobs rather than just residential installs. Residential CCTV upgrades are also mentioned, so they appear to handle both.
What do customers say about Nathan's approach to explaining the system after installation?+
This comes up directly in more than one review. Nathan is specifically praised for conducting hands-on walk-throughs at handover so clients understand how to operate and manage their system themselves. One long-term customer noted he answers technical questions 'in terms that I could understand,' which is relevant if you're not particularly tech-confident and want to be self-sufficient rather than dependent on call-outs for minor queries.
How does EST handle support after the job is done?+
After-sales support is mentioned positively in multiple reviews — one customer described it as 'second to none' following a CCTV replacement. Nathan appears to be personally contactable for follow-up questions, with one reviewer noting they called with a query about a new system and received a clear explanation same-day. That said, reviews don't detail formal service agreements or response time guarantees, so if ongoing maintenance or SLA-backed support is important to you, confirm the specifics with Nathan directly.
Is EST a good fit if I want a security company I can return to for upgrades rather than starting fresh each time?+
Based on the reviews available, yes — several reviewers describe multi-year or even 15-year ongoing relationships with Nathan and the EST team, returning for system upgrades rather than switching providers. That kind of continuity tends to mean the technician already understands your premises and setup, which can reduce the time spent on reassessment. With only 6 total reviews publicly available, this is a pattern rather than a proven statistical norm, but it's a consistent theme across the sample we reviewed.
