Don’t be alarmed – Security systems on the NBN

Sign up to the NBN™ today

As the NBN™ rolls out across Australia, a mix of technologies are being implemented in different areas to bring modern telecommunications to your home. While some of these technologies (particularly NBN™ Wireless and NBN™ Satellite) will not impact the existing copper network used for landline phones, others will.

Areas with Fibre-to-the-Premises (FTTP) will see the copper network disconnected completely around 18 months after NBN™ becomes available. While Fibre-to-the-Node (FTTN) and Fibre-to-the-Building (FTTB) services will utilise part of the copper network, they essentially “take over” the copper line and can’t share it with a traditional phone service. FTTB and FTTN areas will also see any legacy services on the copper network disconnected around 18 months after NBN™ becomes available.

You may wonder how this will affect a security system that relies on a landline phone. You don’t need to be alarmed – we’ve got everything you need to know right here.

Keeping up with the times

We’ve already seen this issue before. When Naked DSL was released, it was all the rage for customers interested in having a broadband service without the need to pay phone line rental. However, most security systems were largely dependent on the phone line whether you actually used it to make phone calls or not.

Australian security providers have long since begun innovating their products to be less reliant on landlines. While security systems can run over broadband services, they are vulnerable during power outages so it’s vital to have a backup solution in place to ensure that your system stays alert. Wireless and mobile technologies have been keenly embraced for this – not only are they typically less susceptible to physical tampering (i.e. there’s no line to cut) some models may even be able to be connected to a backup power source.

Reach out to your security provider

Not all security equipment is compatible with the NBN™. If your home or business has a monitored alarm or another kind of security system installed, you should contact your security provider before making the switch to NBN™ to make sure that everything will work as expected.

Here’s some questions you should ask when discussing your options:

  • Will my alarm work properly when I connect to the NBN™?
  • Once I’m on the NBN™, will my alarm be able to dial out during a power outage?
  • Will my alarm have an alternate communication path in case the primary method fails?
  • Will my alarm “check in” periodically to make sure the communication path is still working?
  • If a mobile service is involved, do I need to arrange my own mobile service or is that included with the security product?
  • Will I need a service call or any new equipment when changing to the NBN™?

It will help if you know which kind of NBN™ technology will be available at your address as it may affect the options your provider can offer you. Before you call your provider, you can check your address on our website to see which kind of NBN™ technology is available in your area.

Once you’re ready to make the switch to NBN™, you can sign up online or call our friendly Sales Team on 13 19 17.

    From my point of view if I can’t have exactly what I had with ADSL2 and can’t tell that the speed is faster then it’s a complete waste of money. I wanted FTTP and got FTTN. This means I can’t have a phone in my bedroom plugged in to the wall. If I run a phone line from my modem down the passage and trip over it causing injury can I sue for injuries due to NBN. I have 25 Mbps NBN and a phone on the desk at my modem. I want 100Mbps for what I pay for the 25 Mbps and I want to be able to plug a phone into the wall in my bedroom as well as my lounge room like I had before. I see NBN as a step backwards and not very well thought out.

  2. Dean Williams says:

    Why does Westnet no longer reply to emails. Why is Westnet support now one of the worst instead of the best. Why is NBN fixed wireless so slow. Why are we unable to get answers to our technical questions. I can’t even get a refund when I have been promised one. ?????

  3. John says:

    What you don’t say in your information about your security system is the enormous cost incurred as a result of the NBN rollout and losing your landline. My security system is $500, and ongoing costs if you don’t use VOIP. Don’t sign up to NBN until you absolutely have to. This advice was given to me by an NBN installer only yesterday.

  4. peter says:

    your website was unable to tell me what type of NBN technology would be available at my address even though NBN pits are being installed in my street and surrounding streets.

    • Leo Yarnold says:

      Hi Peter,

      That is correct! We won’t be able to state what connection type you’ll receive until NBN updates their relevant databases that we access, with the connection type they will employ. For a more accurate assessment, NBN has updated its own Address Checker, with the connection type listed:

      Be aware that NBN does and can change plans for the network roll-out as needs dictate, so don’t that the information offered as gospel until you’re connected!

      – Leo

  5. James says:

    I upgraded to NBN some issues but was fixed.
    NBN is so good as we have a phone wired to modem iinet did for me by remote setup now home phone so good. I use extension cords to move around my house is good as I am a creative thinker.

  6. P.,Parghi says:

    Too many issues with NBN as I am told. I will not change until I have to. It will also cost me heaps to change modem, phones etc. I do require a land line phone – not just the mobile. Soor, but I amnot convinced that iiNET has all the answers – except to make money for them!

    • Leo Yarnold says:

      Thanks for leaving your thoughts!

      The change to NBN has been designed to allow you to use as much as your current equipment as possible. Whilst you may need a new modem, you can use most current landline handsets, on a VoIP service. We’d encourage you to have a chat to our Sales teams on 13 19 17, or if you’re a business customer, why not give our Business team a call on 13 86 89.

  7. GH says:

    To the poster that says he cant have a phone in his bedroom,I would just say that is rubbish.
    I have an IInet FTTN connection and all my extensions work right through the house.
    As I was a Telecom tech in a previous life it was a 20 min job.
    All you need to do is get a tech to rewire as I did and it will all work as it was.

  8. Neil says:

    To Robert Hambrook

    You can have your old phone outlets connected so the phone will work in other rooms just as they have before, you just need to call a licensed cabler

  9. Ian says:

    I am quite tired of being told my NBN is on its way.My neighbor just across the road has had NBN since June 2016 however we still don’t have it. Is the problem with NBN or Telstra?? Here in Bundanoon,I get an average of 5 to 10mbps on ADSL2 which after experiencing for many years, an average of 60+mbps on Transact fibre when I lived in Canberra, is just so frustrating. Not happy NBN!

    • Leo Yarnold says:

      Hi Ian,

      This is quite a common issue with customers and can be attributed to the network simply being rolled out to one side of the street. It can be infuriating to say the least!

      We’ve taken the liberty of checking your area for you and can see that parts of your area are still under construction for NBN Fibre To The Node, so once this is completed by NBN, you’ll be able to move forward.

  10. David says:

    FTTN is the one and only option available in my are soon
    I don’t see why we should be forced to have third world technology
    All because the NBN co want to save money and it looks good for the government saying we have all of Australia connected when all they are doing is just a mix of copper and fibre. As soon as you introduce copper to fibre your speeds will go at copper pace

  11. David says:

    We didn’t even get an option for FTTP we were “told ” you will get FTTN and that’s the bottom line . As soon as you put fibre with copper your internet is governed by the copper and your speeds will reflect that .
    Why is it that we do not get an option

  12. Mark says:

    Personally, I can’t wait till NBN comes to my house. When my area was constructed they put 1 copper line and 1 Telstra broadband- means I’ve been stuck with them! Yes I could use my copper for adsl2 – but would need VoIP- which I have been reluctant to do.
    The person complaining about phone in bed room – run a cat5 cable to you rooms – the u can plug in anywhere – it’s really not that hard – complaining want get you anywhere – or maybe that’s just you.

  13. Ian C. Purdie says:

    @ Robert Hambrook

    I have no problems with my NBN Voip telephone, I found it even more versatile than ever.

    My Iinet T789 Modem has two phone ports. I simply connected my existing Uniden WDECT 2355 cordless phone system to one phone port – this allowed me to continue using walk around phone stations situated in the lounge, the bedroom and the kitchen. No change at all – there’s effectively three different handsets.

    I connected a traditional handset to the second port near the modem.

    The unexpected bonus? Using the walk around phone, I was astonished the hear the traditional handset ring on the second port. Effectively I have two phone lines, and a caller doesn’t receive an engaged signal.

  14. Eman Witheld says:

    Forget the NBN acronym. If you are connected to the old rusted copper wires in the pit, the technology infrastructure is prehistoric. Another issue with moving and falling into it is that after getting connected and tied up with a contract, the speed you have initially experience tends to changes to a slower one…

  15. John Anwin says:

    Whether or not the security system has been adapted to work on the NBN, with FTTN when the mains power fails in the area, there is no connection, phone, internet or any thing else that relies in the physical connection.

  16. Roz Sephton says:

    Also not so happy. I have all these bloody big ugly Satellite dishes on my roof now. One is not geing used anymore and they didn’t take it down for me. Also I am finding it no faster and lots of times I have trouble even getting onto the net. Be very interesting when the landline gets removed. I can’t be without a phone out here and have a crrok ticker and Telstra mobile service does not work full stop. Most of the time Optus does BUT not always, especially on overcast days.

    • Leo Yarnold says:

      Hi Roz,

      NBN should be making contact to have the old dish removed for you, so if this hasn’t happened, we do want to know. Also, with NBN Satellite, your landline isn’t removed – it stays intact, so you won’t be losing that service.

      – Leo

  17. Marie says:

    What a con! I HAVE to sign up to NBN but my home security will not work without big dollars spent. I can’t afford that. And the speeds available at cheapest rate will not be much faster than what I have….even tho they say it will be faster….we do NOT get the speed they say.

  18. John Mandy says:

    I will be dead before NBN reaches me address. I don’t want Turnbull’s stuffed up FTTN.

  19. Alexander Kalo says:

    Dear John, like yourself I’ve been a long time iiNet customer too & had my ADSL2+ cancelled switching over to NBN FTTN. I’m also a licensed electrical contractor for over 30 years with extensive experience in electronics/security systems. I built my home in the early 90’s & still have the original EDM home alarm with built in dialer that used to call up to 3 numbers when it tripped. Now that NBN has taken over my old copper phone line the dialup is not compatible with VoIP & it wouldn’t be a wise choice so I’ll be installing a mobile module that dials preset numbers which could cost me between $50-$150 for the module plus the cheapest prepaid SIM on the market. So in saying this you could monitor your own security system via mobile phone module or simply add an intelligent wireless alarm panel that could work in conjunction with your existing alarm that can dial up to 6 phone numbers & you get a free app that allows you to monitor your system via your mobile phone from anywhere. These are inexpensive options & why pay for someone else to monitor your home or business alarm when you can monitor it yourself. Not sure if this helps in anyway..

  20. John Lewis says:

    I use computer a lot and hope when connected to NBN, it is quicker and cheaper. With some alterations around the house to make it more convenient as well. At this stage it looks like July or even August before connection.

  21. Ken says:

    Why is it mandatory for me to change to NBN at additional cost to me when I will receive a low grade service? There are once off charges and higher monthly charges.

  22. What does it mean for my monitored intruder alarm system when the NBN comes to my area?

    • Leo Yarnold says:

      Hi Dustin,

      As per the article, we’d strongly recommend reaching out to your current security company and discuss your options with them.

  23. Garry Gee says:

    Come on Australia this is not a third world country stick with your ADSL for as long as you can. I went over to a 12MBPS plan with nbn I would be lucky to be getting 1.5 MBPS. Just over the paddock in a straight line from where I live. Their is a tower pumping out over 400MBPS. In frank the internet was so bad last night I turn it off.

    • Leo Yarnold says:

      Hi Garry,

      Have you had a chat to our Support teams about this? We’d strongly recommend doing so, as your post suggests something is very wrong with your service.

      – Leo

  24. chris says:

    nbn has just cost me more with no extra speed yeah keept my same phone no which was great thanks westnet but overall less for my phone usage as i dont have to pay landline fee but the cheapest nbn brought my cost up and i now pay more when you add them both together – but i cant fault westnet for this just the charges for nbn became more expensive

  25. Sandra Tomlinson says:

    I can’t connect to the interne on my iPad if I am more than i15 metre from the box

  26. Hi. I must say that I am not very happy my NBN connection. Used to be able to have a phone in all of my outlets, one of which controlled my security system by a special phone. Tried connecting a cordless system in second router outlet but not very successful as keeps dropping out even if only a single phone is connected still keeps dropping out. Need to have a solution to my issue.

    • Leo Yarnold says:

      Hi Desmond,

      This is one of the common issues we do see with NBN and alarm systems. Ideally, your best option is to engage your alarm provider directly, explaining your setup and what you ideally are looking to do.

      – Leo

  27. NOEL CARTER says:

    FTTN will be connected to my home next week, without requiring our presence, meaning I will connect the iiNet modem.

    Currently, the phone line passes-through a medical alarm (Safety Alert) to the modem-router. Do I continue to use this pass-through method, with NBN? Safety Link has assured me the unit is NBN-compatible, but haven’t advised on the new setup. It has a cellular addition, with battery backup.

    • Leo Yarnold says:

      Hi Noel,

      This is a great question!

      We’d strongly suggest speaking to Safety Link about this, as once NBN is established, you’ll lose dial tone and potentially have to configure the service to work via VoIP. If the internet goes down, your alarm will cease to function via VoIP, so the cellular addition is going to be key here.

      Please be aware that iiNet does not support Priority Assistance for voice services, hence why we recommend speaking to Safety Link about the setup of the alarm once NBN goes active.

      – Leo

  28. Steven Simpson says:

    Hi, I contacted my alarm provider if i change to NBN i will need an added module for the alarm at a cost of $240 and an extra $3 a month for the sim. Added dollars so won’t change untill i really have too

  29. Kim Stone says:

    My husband and I do not live in a gated community, and we are considering security alarms to make sure that we all stay safe during the day and night.

  30. Mark says:

    After having NBN connected our security company advised us that we need to have our alarm system upgraded costing over $1000

    Not impressed at all.

  31. Renae says:

    Disgusting that I have to pay over $1000 to change my alarm system over. How the hell was this not included in the change over to NBN? Oh that’s right it’s all about $$$$. I should not have to pay extra for a service YOU are changing, not me. I rely on this service to feel safe and I cannot afford the extra $$$ to change this over. I will be looking for compensation should anything happen to me or my property!!

  32. Lisa Bria says:

    Hi I’m a iiNet customer with fibre to the home internet and fetch
    Tv bundle just wondering if an home alarm system is possible through this too and if so what’s the cost?

    • Leo Yarnold says:

      Hi Lisa,

      Thanks for dropping by – you’ve asked a very pertinent question and one that we do sometimes see.

      It is possible for alarm systems to work through NBN, but it is wise to consult your alarm provider first. They’ll be able to recommend a solution for you, based on what NBN connection type you have and what your needs are.

      – Leo

  33. Michael says:

    Just a question, why would anyone be liable for an upgrade on their monitored alarm system, due to the NBN rollout…from what I can see I didn’t ask for NBN and I will be no better off with it, does this make sense?

    • Josh McKenzie says:

      Hi Michael,

      We can certainly understand the frustration with having to update peripherals like alarms to prepare for the NBN. With NBN roll-out, this is the hand we’ve been dealt and it’s best to be prepared should your security depend on it. Unfortunately for many that have auxilary services relying on copper line connection with the telephone exchange, this means some old services need a refresh.
