Best security system installers in Joondalup, Wanneroo and the northern suburbs (2026)

Joondalup, Wanneroo and the northern suburbs, from Mindarie and Clarkson down to Wangara, Landsdale and Gnangara: this page ranks the alarm and CCTV installers Google returns for that corridor. Every installer here publishes a street address, carries a Google rating of 4.3 or better, and trades under a name that appears on the WA Police register of licensed security organisations. Nine are ranked here. They are ranked below on Google rating and review volume, with the near misses named and the reason each is not ranked.

Why these 9 and not the rest

An installer is ranked here only if it clears five tests at once: a Google rating of at least 4.3, more than two reviews, a street address on its own Google listing, a Google category of security system installation service, and a trading name that appears on the WA Police register of licensed security organisations. Twenty-four Google listings in the northern searches were looked at. Ten cleared every test; one of them has since come off this page at its request, so nine are ranked, and none of them shares a licence number with another, so each is a separate business. No other installer in the northern searches cleared every test to take the tenth place.

Not being ranked is not a finding that a business is unlicensed. Several of the close calls below are on the register too. They are off the list for category, rating or review count.

Close calls, named

Each of these came up in the same searches with an address in the northern suburbs. None is ranked, for the reason given. None of it is a statement about the quality of their work or their licence.

• Crown Security (Joondalup) – 4.6 from 90 reviews: Google lists it as a security system supplier, not an installer.
• Austguard (Vann Ct) – 4.7 from 46 reviews: Google lists it as a security system supplier.
• Castle Security (Landsdale) – 4.7 from 42 reviews: Google lists it as a security system supplier.
• Comsec Electrical (Wangara) – 4.8 from 55 reviews: Google lists it as an electrician.
• ToSee Security (Wangara) – 5.0 from 12 reviews: Google lists it as a security service, not an installer.
• Connect Security Systems (Wangara) – 5.0 from 2 reviews: under the three-review minimum.
• Perth Homeguard (Landsdale) 4.2 from 29 and Kener Security (Wangara) 4.2 from 21: under the 4.3 rating floor.

What a WA security licence actually tells you

Security installation in Western Australia is licensed by WA Police under the Security and Related Activities (Control) Act 1996. The WA Police licence-types page, read for this page on 25 October 2026, splits licences into two kinds. Agent licences authorise a business to advertise and supply security services. Non-agent licences, including the Security Installer licence, authorise a person to do the work.

The same page says installers who are self-employed or subcontracting under their own ABN must hold their own Security Agent’s licence. That is why the register of security organisations is a fair test for this trade: a business that installs under its own name should be on it.

For an alarm or a camera system, the class to ask about is Class 2. The licence-types page also says the Security Installer licence does not apply to security equipment in vehicles, vessels or aircraft, so a car alarm fitter is a different question.

Two honest limits on what this page checked. It matched each trading name to the WA Police organisations list, which shows the trading name, the licence holder and the licence number. That list is dated 7 September 2026, so a licence granted, cancelled or changed since then will not show. It did not check the individual installer licences of the people each business sends out. Ask for those yourself.

What to ask before booking

Who installs it, and what’s their installer licence number? The agent licence covers the business. The person in your roof space needs their own Security Installer licence for alarm and CCTV work. Ask for the number and the class.

Do I own the equipment and the codes? Some alarm and camera packages lock the panel or the recorder to one company. Ask whether you get the installer code and the admin password at handover, so you can change provider later without replacing hardware.

What does monitoring cost, and for how long am I locked in? Back-to-base monitoring is a separate monthly fee. Get the term, the price after any introductory period, and the exit cost in writing before you sign.

How does the alarm talk to the outside world? If the panel reports over a 4G module, your internet or a phone line, ask what happens when that link drops and whether you get told.

Where does the camera footage go? On a recorder in your house, to a cloud service, or both. Cloud storage usually comes with a subscription. Ask what it costs after the first year.

Red flags

• No licence number on the quote, the van or the website. Ask once. If the answer is vague, ring someone else.
• A long monitoring contract bundled into a “free” or cheap system. Work out the total over the term before you sign.
• Locked equipment. If you won’t get the installer code or the recorder password, you are renting, not buying.
• Cameras sold on megapixels alone. Ask what the picture looks like at night at the distance you care about, such as the driveway or the front door.
• Cash only, no invoice. No invoice means no paper trail if the system fails.

How this list was built

Google data. Ratings, review counts, street addresses and categories come from Google’s own place records for security installer searches across Joondalup and Wanneroo, read on 25 October 2026. Every ranked installer’s place page was opened and its address, category and map position checked.

Weighted score, not raw stars. Each installer is scored with a Bayesian average that pulls a small sample toward 4.5, so 5.0 from 12 reviews does not outrank 4.9 from 710.

The WA Police register. Each trading name was matched on the WA Police list of licensed security organisations, read on 25 October 2026. Two known licence holders from another trade were looked up first as a control, to prove the list was being read correctly.

Nothing here was paid for. Placement on this list cannot be bought. Paid placements are labelled FEATURED and sit outside the ranking. For door locks and lockouts in the same area, see the best locksmiths in Joondalup and the northern corridor.

Questions homeowners ask

Last updated 25 October 2026. Ratings, review counts, addresses and Google categories were read from Google place records on 25 October 2026 and will drift; the weighted scores are calculated from those figures and nothing else. Licence numbers come from the WA Police list of licensed security organisations dated 7 September 2026, read on 25 October 2026. Not being ranked is not a statement about any business’s licence, conduct or quality.
