Common questions about security installers in Chatswood.
Who are the best security installers in Chatswood?
As of October 2026, the 3 highest-ranked security installers in Chatswood, NSW on the Starworks directory are CCTV Online Security (5.0 stars from 63 Google reviews), Ifocus Security (5.0 stars from 49 Google reviews) and AJH Safety Solutions | CCTV & Alarm Systems Sydney (5.0 stars from 39 Google reviews). Every figure here is computed from Google review data that Starworks collects for security installers in Chatswood, NSW, recalculated when this page rebuilds. Placement on this list cannot be bought.
How many security installers does Starworks rank in Chatswood?
Starworks ranks 26 security installers in Chatswood, NSW, holding 516 Google reviews between them. Across the 26 the median rating is 5.0 stars from a median of 15 reviews. Of the 26, 22 are rated 4.5 or better. The most-reviewed carries 79 reviews, more than the top-ranked security installer holds, which is why rating alone does not set the order.
What star rating should I expect from a good security installer in Chatswood?
The median Google rating across the 26 security installers Starworks ranks in Chatswood, NSW is 5.0 stars, and 22 of them sit at 4.5 or above. A rating at or near that median is ordinary for security installers in Chatswood, NSW 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 Chatswood have?
The median security installer Starworks ranks in Chatswood, NSW carries 15 Google reviews. The most-reviewed of them carries 79.
How does Starworks rank security installers in Chatswood?
Starworks gives every security installer in Chatswood, NSW 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 Chatswood 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 Chatswood, NSW. 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 26 distinct security installers in Chatswood, NSW rather than a longer list of repeats.
How often is this list of security installers in Chatswood updated?
This ranking of security installers in Chatswood, NSW 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 Chatswood?
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 Chatswood, NSW carries 15 Google reviews at 5.0 stars.
