Mainsafe Australia
Justin personally sets up your camera app and walks you through the system before he leaves — every time.
The pattern that matters most for hiring decisions is the combination of punctuality, tidy workmanship, and a clear walk-through of the system before he goes — all three appear together in enough reviews to be reliable signals rather than flukes. Mainsafe's work spans residential CCTV and downlights through to full commercial security and electrical cabling, so if your job crosses both categories, it's worth asking Justin directly whether it falls within his licensing scope for the electrical component.

About Mainsafe Australia
Justin leads Mainsafe Australia as a sole trader, and his name appears repeatedly across reviews — customers credit him directly for CCTV camera installs, downlight fitting, Tesla battery installation, and full electrical and security cabling for commercial fitouts. Reviews suggest he works across both residential homes and multi-site businesses, with restaurants and office buildings among the commercial jobs mentioned. What stands out from cross-referencing the reviews is how consistently Justin closes out a job: customers note he sets up the mobile app and remote access for camera systems, walks the homeowner through how to use everything, and leaves the site clean before he goes. He brings an apprentice on larger jobs, and even that team dynamic gets called out positively — a sign the handover between crew members doesn't create gaps in quality. The work spans more than security: electrical cabling, kitchen renovation power and lighting, and EV battery storage have all come up in recent reviews, making Mainsafe worth contacting for jobs that sit across the security-electrical boundary. For homeowners who've had unreliable tradies before, the punctuality and accountability comments across multiple reviews are worth noting.
Best for: residential CCTV installations where you want a full system walkthrough, multi-site commercial security and electrical cabling, and jobs that cross the security-electrical boundary such as new builds or renovation fitouts.

What areas does Mainsafe Australia service?+
Mainsafe Australia is based in Greystanes, NSW, and reviews mention jobs across Sydney including Condell Park and multi-site commercial work. The business operates as a sole trader with a small crew, so coverage likely centres on Greater Western Sydney. For jobs further afield, it's worth calling Justin directly to confirm whether he travels to your area.
Does Mainsafe Australia handle commercial security jobs, not just homes?+
Yes — commercial work is well-represented in the reviews. Customers mention full electrical and security cabling for a new office building and camera installations across two restaurant locations. One business review notes they left Justin and his team on-site unsupervised and made them their preferred security provider, which suggests confidence in independent execution on commercial sites.
Will Justin show me how to use the security system after installation?+
This comes up repeatedly in reviews as a specific positive. Customers note Justin sets up the mobile app, configures remote access, and walks them through how to use the system before leaving — not just completing the hardware install. If you want a particular platform or app configured, it's worth mentioning that when you get a quote so he can confirm compatibility.
Does Mainsafe do electrical work beyond just security cameras?+
Reviews confirm electrical jobs outside the security category: downlight installation, kitchen renovation power and lighting, and a Tesla home battery install are all mentioned. Justin appears to hold electrical qualifications covering these services, but if your job involves specific electrical work, ask him directly to confirm licensing scope before booking.
What do customers say about pricing at Mainsafe Australia?+
Reviews mention 'fair prices' and 'best quality work out there and fair prices' but don't go into specific figures. No reviews raise concerns about cost or unexpected charges. For an accurate quote, you'll need to contact Justin with the specifics of your job — the number of cameras, cabling complexity, and whether it's residential or commercial will all affect the price.
