Best security system installers in Belmont, Welshpool and Cannington (2026)

Belmont, Welshpool and Cannington: this page ranks the alarm and CCTV installers Google returns for Perth’s inner south-east, from Belmont and Cloverdale down through Kewdale and Welshpool to Cannington. Every installer here gives a street on its Google listing, 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. Three cleared all of that. They are ranked below on Google rating and review volume, with the near misses named and the reason each is not ranked.

Why these 3 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 on its own Google listing in Belmont, Cloverdale, Kewdale, Welshpool or Cannington, a Google category of security system installation service, and a trading name that appears on the WA Police register of licensed security organisations. Forty-seven different businesses came back across four Google searches for Belmont, Cannington, Welshpool and Kewdale, and Maddington and Kenwick, and eleven place pages were opened. These 3 cleared every test, and none of them shares a licence number with another, so each is a separate business.

Legacy Security and Security Perth are close: 0.0218 apart on the weighted score, which is a real but small gap. Legacy’s perfect 5.0 from 101 reviews edges Security Perth’s 4.8 from 325. Either is a reasonable first call. Installers come to you, so the address mostly tells you where the business is based.

Three is a short list. We would rather rank three that clear every test than pad it with businesses from further out. Canning Vale, Maddington, Kenwick and the suburbs south of them are not on this page; installers based there are left for a page of their own.

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, review count, address or area.

Close calls, named

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

• LKR Security (James St, Cannington) – 4.8 from 28 reviews: Google lists it as an installer with a street in Cannington, but we could not find its trading name on the WA Police organisations list, and its website would not load on 31 October 2026, so no licence number could be matched. That is a gap in what we could check, not a finding against the business.
• Ai Secure Homes (Birnam Rd, Canning Vale) – 5.0 from 36 reviews, and Genius Security (Forrestdale) – 5.0 from 14: both are on the register and listed by Google as installers, but their addresses are south of the area this page covers.
• Securelec – 5.0 from 40 reviews: on the register and listed by Google as an installer, but its Google listing gives no street address, so it cannot be placed in this area.
• Hawk Security Installations (Firby St, Cloverdale) – 4.7 from 20, Gardas Security (Belmont) – 4.7 from 31, Select Security – 4.9 from 11, and Security West (Willetton) – 5.0 from 280: Google lists them as security system suppliers, not installers.
• Big Brother Security (Belmont Ave, Belmont) – 4.9 from 94 reviews: Google lists it as an auto electrical service. Vehicle security sits outside the Security Installer licence, so it is not compared with home and business installers here.
• Kada Systems (Belmont) – 4.2 from 6 reviews, and API Access & Security (Belmont) – 3.9 from 7: 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 31 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.

Home or warehouse? Around Welshpool, Kewdale and Belmont a lot of jobs are factories, yards and offices as well as houses. Ask whether the installer does commercial work, whether the system can cover a yard or a roller door, and who responds to an alarm after hours.

Where does the camera footage go? On a recorder on site, 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, streets and categories come from Google’s own place records for security installer searches across Belmont, Cannington, Welshpool, Kewdale, Maddington and Kenwick, read on 31 October 2026. Every ranked installer’s place page was opened and its address and category checked.

Weighted score, not raw stars. Each installer is scored with a Bayesian average that pulls a small sample toward 4.5, so 4.7 from 19 reviews does not count for as much as 4.8 from 325.

The WA Police register. Each trading name was matched on the WA Police list of licensed security organisations, read on 31 October 2026. Three known licence holders 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.

Questions homeowners ask

Last updated 31 October 2026. Ratings, review counts, addresses and Google categories were read from Google place records on 31 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 31 October 2026. Not being ranked is not a statement about any business’s licence, conduct or quality.
