Frequently Asked Questions
Common questions about security installers in Adelaide.
Who are the best security installers in Adelaide?
As of October 2026, the 3 highest-ranked security installers in Adelaide, SA on the Starworks directory are Adelaide Home Control (5.0 stars from 61 Google reviews), HSA Australia Group (4.8 stars from 26 Google reviews) and Manuell Security and Data (5.0 stars from 12 Google reviews). Every figure here is computed from Google review data that Starworks collects for security installers in Adelaide, SA, recalculated when this page rebuilds. Placement on this list cannot be bought.
How many security installers does Starworks rank in Adelaide?
Starworks ranks 36 security installers in Adelaide, SA, holding 323 Google reviews between them. Across the 36 the median rating is 4.7 stars from a median of 5 reviews. Of the 36, 20 are rated 4.5 or better.
What star rating should I expect from a good security installer in Adelaide?
The median Google rating across the 36 security installers Starworks ranks in Adelaide, SA is 4.7 stars, and 20 of them sit at 4.5 or above. A rating at or near that median is ordinary for security installers in Adelaide, SA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established security installer in Adelaide have?
The median security installer Starworks ranks in Adelaide, SA carries 5 Google reviews.
How does Starworks rank security installers in Adelaide?
Starworks gives every security installer in Adelaide, SA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a security installer in Adelaide with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer security installer with a handful of excellent reviews may still be the right choice in Adelaide, SA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same security installer not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 36 distinct security installers in Adelaide, SA rather than a longer list of repeats.
How often is this list of security installers in Adelaide updated?
This ranking of security installers in Adelaide, SA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my security installer business ranking in Adelaide?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median security installer Starworks ranks in Adelaide, SA carries 5 Google reviews at 4.7 stars.
