How to View CCTV on Your Phone Securely | Sydney

Being able to view CCTV on your phone is one of the most useful things a camera system can do. But the same connection that lets you watch from anywhere can let others in, if the system is left with default passwords or old software.

Here is how to view CCTV on your phone safely: how remote viewing works, where the risks are, and an 8 point check to lock it down.

How do you view CCTV on your phone?

Your cameras send video to a recorder at your home, usually called an NVR. The recorder connects to the internet, and an app on your phone connects to the recorder so you can watch live or play back footage.

Most brands connect the app through their own service, so you just scan a code or sign in. Some older setups instead open a path straight from the internet to the recorder, often by changing settings on your modem. That second way needs more care.

Where are the risks?

The biggest risks are simple ones. Default passwords that were never changed. Short passwords that are used on other accounts too. Recorders and cameras that have never had a firmware update. And old logins for people, like a previous tenant or tradie, who no longer need access.

Any of these can let someone else see your cameras, or change your settings.

Are some CCTV systems more secure than others?

Yes. Some systems are far more vulnerable than others, especially cheap off the shelf kits. The professional grade systems we install are built with strong security behind the scenes, so the risk is very low when they are set up properly.

Even so, every device should have its default password changed. When we install a system, we set the passwords ourselves using our own secure company setup. That also means our team can give you tech support quickly if you ever need help.

If you are choosing a system, use a reliable brand and have it installed properly. Speak to our team about the options for your home or business.

The 8 point check

Start with the four that matter most. Change the default password on the recorder. Change the default passwords on every camera. Use a long password you do not use anywhere else. Make sure the recorder's firmware is up to date.

Then tighten things up. Turn on two step login in the app if it offers it. Give each person in the household their own login. Remove logins for anyone who no longer needs them. And know who installed the system and how it connects, so you know who to ask if something changes.

Does viewing on your phone use a lot of data?

Live viewing uses mobile data, especially in high quality. Most apps let you pick a lower quality stream for mobile, which uses less. Recordings stay on the recorder at home, so how long footage is kept does not depend on your phone. We cover that in how much NVR storage you need.

What should a good installer do?

A good installer uses a reliable brand, sets unique passwords, updates firmware before handover, sets up the app with you, and shows you how to find and save footage. That handover matters as much as the cameras. Learn more about our CCTV installations.

Common questions

Can my CCTV be hacked?

Any internet connected device can be a target, and some systems are more vulnerable than others. A reliable brand, installed properly with the default passwords changed and firmware kept up to date, keeps the risk very low.

Do I need internet for my CCTV to record?

No. Cameras can keep recording to the recorder at home without internet. You only need internet to watch or play back footage while you are away.
