    Outstanding service from TNJ Security and Trung! I reached out to Trung from TNJ Security for help with a site in Sydney, and he was fantastic from start to finish. He took my call personally, scheduled a site visit within a week, and quickly diagnosed the issue — a failed switch that had taken several of our cameras offline. Despite never having been to the site before, Trung methodically reverse-engineered the system, identified the root cause, and had everything back online within just six hours. His expertise and professionalism really showed throughout the process. To top it off, he even referred me to Serious Security Melbourne for a related job in Victoria — another great experience thanks to his recommendation. Highly recommend Trung and the TNJ Security team — fast, knowledgeable, and genuinely great to work with!

Frequently asked questions

How much do security installers typically charge?
Costs vary widely depending on the system type, number of devices, wiring access and whether the installer supplies hardware. The page shows live pricing for typical jobs, which is useful for comparing options. After-hours attendance, emergency call-outs and any required repairs or replacements generally increase the total cost.
Do security installers charge call-out fees?
Call-out fees are common and usually cover travel and the initial assessment or diagnosis. Many installers list the call-out separately from labour and materials, and after-hours or urgent attendances typically attract higher rates. It’s reasonable to ask providers how they apply call-out fees and any minimum charges.
Do security installers need a licence in Australia?
Yes. Security installers generally need a state security licence in every Australian state and territory; in NSW this is administered by the NSW Police Force — Security Licensing & Enforcement Directorate (SLED). Providers should usually be able to provide their licence number and evidence of insurance, and may hold industry association memberships such as ASIAL or the MLAA.
