Can someone really snoop on your security cameras without touching a single wire? Unfortunately, yes. It happens more than you’d think. This guide walks you through how cameras get broken into, what clues to watch for, and the dead-simple steps that keep them locked down.
CGF Security has been putting in and looking after CCTV systems across the Sutherland Shire, Cronulla, and wider Sydney for close to ten years. We’re licensed for both security work and electrical. We’ve seen the mistakes people make over and over. Here’s what keeps your cameras safe in 2026.
How Do Hackers Break Into a Security Camera?
Most people picture a genius typing code in a dark room. It’s way less exciting than that.
Hackers just scan the internet for cameras with easy-to-guess passwords. If your camera’s still running on the factory login-like “admin” and “password”-they’ll find it. In one test, a camera was taken over in two seconds using “root” and “root”. No special skills needed.
Think about it like leaving your front door open with a neon sign saying “come in.” Hackers don’t need to pick a lock. They just push the door.
The big reasons cameras get broken into:
Where Is All My Power Going?
- Default passwords never changed. If your login is still "admin" or "123456," you're an easy target.
- Old firmware with known holes. The company that made your DVR might have fixed a bug years ago. But if you never hit update, that hole is still there.
- Cameras wide open to the internet. No firewall, no VPN, nothing stopping someone from knocking.
Are Wireless Cameras Easier to Hack Than Wired Ones?
Short answer? Yes. But there’s more to it.
Wireless cams talk over Wi‑Fi. If your Wi‑Fi password is flimsy, someone nearby can hop on your network. Even if they don’t steal anything, they might poke around your cameras. Worse, Wi‑Fi jammers are showing up in Australian suburbs now.
In April 2026, a Melbourne father woke up and found two cars gone from his garage. The thieves used a cheap jammer that knocked every wireless camera on the street offline. He said the only camera that caught anything was a wired one plugged into a hard drive. His neighbour’s cameras? All dead. Even his own wireless cameras were useless.
Wired cameras don’t send a radio signal. To mess with them, someone has to touch the cable. That’s a lot harder than jamming Wi‑Fi from a car. So for your driveway, front door and garage, a professionally run wired camera is still the safest bet.
How Do I Know If My Camera Is Already Hacked?
- The camera moves by itself. If it's a PTZ camera and it pans or tilts when nobody's touched the app, someone else might be driving it.
- Strange sounds from the speaker. Some cameras have a two-way mic. If you hear clicks or voices you didn't make, that's a red flag.
- The app keeps kicking you out. If your camera app suddenly says wrong password, someone may have changed the login.
- Odd gadgets on your Wi Fi. Check the list of connected devices in your router settings. See something you don't recognise? Could be trouble.
- Your internet data usage jumps. A hacked camera can be busy sending footage somewhere else. That uses bandwidth.
Do the New Australian Laws Help?
From 4 March 2026, Australia got new rules for consumer smart devices sold in stores. This covers security cameras and doorbells.
The rules force manufacturers to do three things:
- No more standard passwords that are the same for every unit. Each camera needs a unique password or makes you set your own.
- They have to give a way to report security bugs-and actually reply to you.
- They have to tell you how long the camera will get security updates. So you'll know if it's still safe to use.
That’s great for new cameras you buy now. But millions of older cameras already on walls around Sydney aren’t fixed by this law. Your two-year-old doorbell is still as secure as its last update. The law is a step forward, but it doesn’t magically protect the camera you already have.
Still, it shows the government is finally taking smart home security seriously.
How Do I Stop Someone Getting Into My Cameras?
- Change every default password on day one. Your DVR, your app, your camera's admin login-none of them should use what came in the box. Use a long passphrase. Even better, let a password manager make one up.
- Update the firmware regularly. Every few months, open the app and check for updates. Install them. If your recorder hasn't seen an update since 2014, those old security holes are public knowledge by now.
- Turn on two-factor authentication. If the camera brand offers it, switch it on. Even if someone steals your password, they can't get in without that code from your phone. This one step stops most break ins.
- Put cameras on their own network. Many routers let you make a guest Wi Fi or a separate VLAN for gadgets. Stick your cameras on that. If one gets hacked, the bad guy can't jump to your computer or phone
- Turn off remote access if you don't use it. Lots of people turn on cloud access during setup because it's easy. But if you never check your cameras when you're out, you're leaving a door open for no reason. Keep it simple.
Does It Matter Who Installs the System?
It matters a lot. A lot of people grab a wireless kit from Bunnings and do it themselves. The box makes it look easy. But most DIY jobs we see around Sydney have at least one major mistake-passwords still default, old firmware, cameras sitting on the main Wi Fi with the family computer.
When a licensed installer like CGF Security sets up your system, they do more than just mount the brackets. They lock down the network so only your devices can talk to the recorder. They strip out features you don’t need. They make sure the cabling meets Aussie rules-which your insurance cares about.

We give a lifetime workmanship warranty on every install. That’s not common. It means if something doesn’t work right, we come back. Cameras aren’t a set and forget thing. They need occasional firmware updates, password checks, and sometimes a hardware swap. We handle all that.
What People Mostly Ask
Some brands have a better track record than others. But even an expensive camera left with the default password is wide open. The way it’s set up matters more than the logo.
No system is 100% safe. But wired cams can’t be jammed from a car. They don’t drop out when your Wi‑Fi gets crowded either. For places like driveways and front doors, they’re the strongest choice.
If your Wi‑Fi password is “password123” or you never changed the router’s admin login, then yes. Once someone’s on your home network, they can poke around every device. Secure your router, update it, and change that admin password.
Check it every three months. Set a reminder in your phone. Ten minutes of clicking beats having your feed end up somewhere it shouldn’t.
Your cameras still work the same. The law applies to new products sold, not the stuff already on your wall. But if your system is getting on in years and no longer gets updates, it’s worth having someone check if it’s still safe.
We do both. Add-on cameras, upgrades, getting a tired system back in shape, and ongoing servicing. If your gear’s been untouched for years, we’ll tell you straight what needs fixing and what’s still fine.
The Bottom Line
Your cameras are there to watch over your home, not open the door to strangers. But a camera with the factory password, ancient firmware, and no network separation is basically handing out keys.
The good thing? Fixing it takes an afternoon. Change the passwords. Run the updates. Move the cameras to a separate network. Or get a pro to sort it out for you.
If you’re in Sutherland Shire, Cronulla, or anywhere around Sydney and you’re not sure your system is locked down tight, give CGF Security a call. Nearly ten years in the game, licensed for security and electrical, and no pushy sales talk. Just straight advice and a job done properly.
