Licensed electrician and security installer. We design and install alarm systems and CCTV for homes and businesses across Perth.
What We Do
We tailor every security system to the property. One licence covers the alarm and the cameras, the other covers the wiring that feeds them, and I carry both. That is why there is no second trade to book and no gap where one contractor blames the other.

Money Back
Three rebates can take money off a new security system in WA. Which one applies depends on who you are and where you live.
Under the SBDC’s Small Business Resilience Program CCTV Rebate, the WA Government refunds 50% of a new internal CCTV system, excluding GST, up to $2,000, for eligible retail and customer-facing businesses with fewer than 20 employees. Applications opened on Monday 19 October 2026 and close when the funding runs out. You need pre-approval before the install.
Small business CCTV rebate guide →WA Seniors Card holders can claim up to $400 per household on CCTV, alarms and smoke alarm work through the state Safety and Security Rebate. It runs all year.
Seniors rebate and how to claim →Some Perth councils run their own CCTV rebates. Most work on a yearly budget that closes once it is spent, and need approval before you buy.
Council rebates guide →Rebate rules change and funding runs out. Last checked 14 October 2026. Check the official page before you buy.
Featured System
Ajax is the alarm system Dextel installs: run from your phone, with a sleek, minimal design that doesn't look like a standard alarm. Every system is designed around the property it goes into.
When I first came across Ajax, I was sceptical. I asked the wholesaler more than once: where's the keypad? The answer never changed. You don't need one unless you want one; everything runs from the app or a keyfob.
So I tested it first, on a friend's house, and I was speechless at how good it was. After years of crawling through roof spaces running alarm cable, it was a different job.
I dropped the Bosch Solution 6000, my favourite system until then, and I've installed Ajax ever since.
