Daehn Security Cameras, Access Control & Telecommunications
Three reviewers name Sebastian specifically — across security installs, fibre prep, and WiFi mesh jobs.
That breadth suggests this isn't a one-trick crew. The small sample we worked from limits how confident we can be about any single specialty, so if your job falls outside security cameras (say, a satellite dish or mesh network), ask directly whether they've done that specific type of work recently — the reviews suggest yes, but confirming scope and timeline upfront is always worth doing with any tradesperson.

About Daehn Security Cameras, Access Control & Telecommunications
Sebastian leads the Daehn team and appears across multiple jobs — from NBN fibre conduit runs to WiFi mesh installations — consistently praised for taking time to confirm requirements before starting work. Alex and Antonio assist on installations and are noted for punctuality and keeping clients updated mid-job, while Rene is specifically mentioned alongside Sebastian on networking and communications work. The business spans a broader scope than the 'Security & CCTV' category implies: reviews reference antenna and satellite installations, NBN fibre preparation, WiFi mesh systems, access control, and security camera installs across both residential and commercial properties. With roughly 26 years of operation, the team handles everything from running conduit and string lines for fibre connections to full antenna arrays that stay hidden from street view — a detail one customer called out specifically. Their working style is hands-on and methodical: they listen first, confirm scope, work through the job, then clean up — a pattern that comes through across several different job types.
Best for: residential antenna and satellite installs where street visibility matters, NBN fibre connection preparation and conduit work, WiFi mesh network setups, and commercial or residential security camera and access control installations.

What types of jobs does Daehn Security handle beyond security cameras?+
Reviews mention a broader range of work than the business name implies, including WiFi mesh system installations, antenna and satellite dish setups, and NBN fibre conduit preparation. Sebastian and Rene are specifically named on the networking and communications side, suggesting this isn't just a CCTV-only operation. If you have a job that crosses into home networking or TV signal work, it's worth asking whether they can bundle it with a security install. The business also covers access control systems according to their listed services.
What do customers say about pricing?+
Two customers in our sample specifically called out affordability — one described the pricing as 'very reasonable' for a building security installation, and another signed off with 'very affordable services' after an NBN conduit job. That's a small sample to draw firm conclusions from, so it's worth getting a quote and comparing, but nothing in the reviews suggests pricing has been a sticking point for customers.
Who are the technicians you're likely to deal with?+
Sebastian appears most frequently across reviews and seems to handle a wide range of job types including security installs, fibre prep, and mesh networking. Alex and Antonio are mentioned as part of the install crew and are praised for arriving on time and communicating during the job. Rene is named specifically alongside Sebastian on a WiFi mesh installation. Based on the reviews available, you're likely dealing with a consistent small team rather than rotating contractors.
Does Daehn Security work on commercial as well as residential properties?+
Yes — one reviewer explicitly mentions a building security system installation in what reads as a commercial context, praising the communication and scheduling involved. Residential jobs also appear across the reviews, covering homes needing antenna work, WiFi mesh, and NBN preparation. The business appears comfortable across both settings, though if you have a large commercial project, it's worth discussing scale and timeline directly with them.
What areas around Monterey does Daehn Security cover?+
The business is based in Monterey, NSW, but the reviews don't specify exactly which surrounding suburbs they travel to. Given the mix of residential and commercial jobs mentioned, they likely cover a reasonable radius across Sydney's south and inner south. The best approach is to contact them directly with your postcode — reviews don't mention any travel fee complaints, but confirm this when you enquire.
