A CCTV system is supposed to protect your property. But a modern IP camera system is also a computer network: cameras, a recorder, a router, apps and user accounts, all connected to the internet. If any of those is poorly secured, the system meant to watch for intruders can become the way in.
The good news is that most CCTV hacking is not sophisticated. It relies on easy mistakes: factory-default passwords, outdated firmware, and cameras exposed directly to the internet. This guide explains how CCTV systems get compromised, gives you a prioritised 12-step checklist to stop it, and tells you exactly what to do if you think you have already been hacked.
SEFA Security Systems has designed and installed SIRA-approved security systems in Dubai for more than 20 years, so the advice below is written for UAE homes and businesses.
Steps to Quickly stop your CCTV from being hacked
To stop your CCTV system from being hacked, do these ten things in this order:
- Change every default password to a unique, long one.
- Update firmware on cameras, the NVR/DVR, the router and the viewing app.
- Never expose cameras to the internet with port forwarding or UPnP.
- Use secure remote access: a VPN or a reputable vendor cloud with two-factor authentication.
- Put cameras on a separate network (VLAN or dedicated switch/SSID).
- Prefer wired PoE cameras where possible, and use WPA3/WPA2-AES for any Wi-Fi.
- Turn off services you don’t use (Telnet, FTP, UPnP, unused ports).
- Give each person their own account with only the access they need, and remove old users.
- Lock down the recorder physically and protect stored footage.
- Have a professional audit the system at least once a year.
The rest of this guide explains each step, why it matters, and how to do it.

Can CCTV cameras be hacked?
Yes. Any camera or recorder connected to a network can be attacked. This applies to IP cameras, NVRs, and also analogue systems whose DVR is connected to the internet. A purely analogue camera linked by coaxial cable to a DVR that is not online has very little digital exposure. The DVR is the point of risk once it is connected to a network.
Attackers go after CCTV for different reasons:
- To spy: watching your home, office or staff, or learning when a property is empty.
- To steal footage: recordings can contain faces, vehicle plates, and daily routines.
- To use the device as a stepping stone: a compromised camera on your main network can give access to computers, servers or point-of-sale systems.
- To enlist it in a botnet: criminals take over thousands of cameras to attack other targets, and you may never notice.
How CCTV systems actually get hacked
| How attackers get in | What happens | The fix (step) |
| Default or weak passwords | Many devices ship with well-known default logins. Automated tools try them across the internet. | Steps 1, 2 |
| Outdated firmware | Known vulnerabilities stay open on devices that were never updated. | Step 3 |
| Cameras exposed to the internet | Port forwarding or UPnP opens a direct door to the camera or recorder. | Steps 4, 7 |
| Flat network | A hacked camera gives access to everything else on the same network. | Step 5 |
| Insecure Wi-Fi | Weak Wi-Fi security lets attackers join the network or intercept traffic. | Step 6 |
| Account takeover | Reused passwords from other breaches are used to log into your camera app or cloud account. | Steps 2, 8 |
| Too many admin accounts | Shared logins, ex-staff accounts and over-privileged users widen the attack surface. | Step 8 |
| Physical access | Someone plugs into the NVR, resets it, or removes a hard drive. | Step 9 |
| Unsupported or unbranded devices | No security updates are ever published. | Steps 3, 12 |
A real-world example: why firmware updates matter
In 2021, a critical vulnerability (tracked as CVE-2021-36260) was found in the web server of many IP cameras and recorders from a major manufacturer. It allowed a remote attacker to take control of an affected device. The manufacturer released a fix in September 2021, and the US cybersecurity agency CISA urged owners to apply it. Yet in 2022, researchers reported more than 80,000 vulnerable devices still exposed online across 2,300 organisations in 100 countries. A botnet had already used the flaw to spread in December 2021, and CISA later added it to its catalogue of known exploited vulnerabilities.
The lesson is not about one brand. Every major manufacturer publishes security advisories. The difference between a safe system and a hijacked one is whether someone applied the fix. A strong password alone does not help against a flaw like this, which is why updating and not exposing devices to the internet both matter.

Why this matters in the UAE
- Privacy law. Under the UAE Personal Data Protection Law (Federal Decree-Law No. 45 of 2021, in force since January 2022), information that identifies a person, including an image or voice, counts as personal data, and organisations that hold it must protect it. CCTV footage of identifiable people is therefore personal data. Some executive regulations and enforcement details are still developing, so businesses should confirm their obligations with a legal adviser.
- Criminal law. Accessing someone else’s camera or system without permission is an offence under UAE cybercrime law. If you are the victim, you have the right to report it (see the incident response section).
- Business risk. A leaked video can expose staff, customers, cash-handling routines, or confidential areas. A compromised camera can also be a path into your office network.
- Regulated installations in Dubai. SIRA-regulated CCTV systems must meet specific requirements. [Confirm with SEFA’s compliance team and add one sentence: whether firmware or configuration changes on a SIRA-registered system should be coordinated with the approved installer, and link to the relevant SIRA guidance.] Always use a SIRA-approved installer for commercial sites.
Warning signs your CCTV system may be hacked
Look for these. Two or more together is a strong signal:
- Logins to your camera app or NVR from unknown devices or locations
- Settings changed that you did not change (users, passwords, recording schedules, network settings)
- Recordings missing or the recorder suddenly full, or the time/date shifting
- Motion alerts or notifications stopping, or alerts you did not set up
- A camera moving, rebooting or responding strangely, or its LED behaving differently
- Unusual network activity: slow internet, or the recorder uploading large amounts of data
- You are locked out of your own device or account
The 12-step CCTV security checklist
Step 1: Change every default username and password
Default credentials are public knowledge, and automated tools try them constantly. Change the default admin username if the device allows it, and set a unique password for every camera, the NVR/DVR, the router and each user account. Use at least 12 to 16 characters, mix words and symbols, and never reuse a password from another account. A password manager makes this practical.
Step 2: Use strong, unique passwords and turn on two-factor authentication
If your system or app supports two-factor authentication (2FA), turn it on for every account, especially anything with remote access. Account takeover from reused passwords is one of the most common ways home cameras are accessed.
Step 3: Keep firmware updated, everywhere
Update the cameras, the NVR/DVR, the router, and the viewing app. Many cameras do not update themselves, so check manually. Subscribe to your manufacturer’s security advisories. A practical routine: check for updates every three months and whenever a vulnerability is announced. Update every camera individually, and confirm the version number afterwards. Replace devices that no longer receive updates.
Step 4: Do not expose your cameras to the internet; use secure remote access
This is the highest-impact network step. Avoid port forwarding and UPnP for cameras or recorders. They open a direct path from the internet to the device, where automated scanners will find it. For remote viewing, use one of:
- A VPN into your network (the strongest option for businesses)
- A reputable vendor cloud or P2P service that encrypts the stream and supports 2FA
Remote access through a vendor service is only as safe as the vendor and your account security, so choose established brands and protect the account.
Step 5: Put your cameras on a separate network
A separate network (a VLAN, a dedicated switch, or at minimum a separate Wi-Fi network) stops a compromised camera from reaching your computers and servers, and the reverse. Add firewall rules so cameras can only talk to the recorder and the services they need, and block unnecessary traffic in and out. This is standard practice in professional installations and is easiest to do at installation time.
Step 6: Prefer wired PoE cameras, and secure any Wi-Fi properly
Wired Power-over-Ethernet (PoE) cameras remove the Wi-Fi attack surface and are generally more reliable for key views such as entrances. Where Wi-Fi is needed, use WPA3 if available (otherwise WPA2 with AES), a long passphrase, and a dedicated SSID for cameras. Disable WPS. Wireless cameras are practical for many homes, but they must be set up with the same care.
Step 7: Turn off features and services you don’t use
Disable anything you do not need: Telnet, FTP, SSH if unused, UPnP, remote guest access, and unused ports or protocols. Enable HTTPS for the web interface, and use encrypted streaming where supported. Every unused service is one more thing that can be attacked.
Step 8: Control who has access
- Give each person their own account (no shared logins).
- Grant least privilege: viewing only for most users, admin for very few.
- Remove accounts immediately when staff or contractors leave.
- Limit login attempts and review access logs regularly.
- Make sure installers do not leave temporary or default accounts behind.
Step 9: Secure the recorder and the footage
The NVR/DVR is the heart of the system. Keep it in a locked cabinet or room, protect its local console and USB ports, and protect stored footage. Use encryption for stored and transmitted video where the system supports it. Control exports: footage that leaves the building is where many leaks happen. For businesses, define who may export footage and how long it is kept.
Step 10: Monitor, log and get alerts
Enable event and login logs, and send alerts for failed logins, new users and configuration changes where possible. Larger sites should send logs to a central system. Checking logs is how you spot a problem before footage is stolen.
Step 11: Protect power and resilience
A UPS keeps the recorder and network switch running through power cuts and gives you time to shut down cleanly. For critical sites, keep an off-site or secondary backup of key footage and an offline copy of your configuration, so you can recover after an incident.
Step 12: Choose secure equipment and get a regular security audit
Buy from authorised suppliers and established manufacturers that publish security advisories, provide long-term firmware updates, and force a password change at setup. Avoid unbranded cameras with no update path. Then have the system audited at least once a year: firmware versions, accounts, open ports, network segmentation and physical security.

Villa vs business: what to prioritise
| Villa / home | Business / commercial | |
| Biggest risks | Default passwords, reused app passwords, exposed cameras via port forwarding, weak Wi-Fi | Flat network, many users and shared logins, unpatched fleet, footage exports, compliance |
| Top 3 priorities | 1) Unique passwords + 2FA 2) Update firmware 3) No port forwarding; use app/VPN | 1) Separate VLAN with firewall rules 2) Role-based accounts + logging 3) Patch management and annual audit |
| Remote access | Reputable vendor app with 2FA | VPN, or managed secure access |
| Network | Dedicated camera SSID or wired PoE | VLAN, managed PoE switch, firewall |
| Extras | Router hardening, guest Wi-Fi separate | Retention policy, data-protection review, incident plan, SIRA-approved installer |
What to do if your CCTV has been hacked
Move quickly and calmly. A sensible order:
- Isolate. Disconnect affected cameras and the recorder from the network (unplug the network cable or power them off) to stop live viewing and data theft.
- Preserve evidence. Before wiping anything, note what you saw (screenshots, log entries, dates and times). If a crime is involved, keep relevant footage and logs.
- Change passwords. From a clean device, change the passwords for the router, recorder, cameras, the viewing app and any email account linked to them. Turn on 2FA.
- Update and reset. Update firmware on all devices. Factory-reset compromised devices, then reconfigure them with new credentials. Check your router for unknown settings or port forwards.
- Rebuild safely. Re-establish the system with the checklist above, especially separate networking and no port forwarding.
- Report it. In Dubai, you can report cybercrime through the Dubai Police eCrime platform (ecrime.ae), the Dubai Police app, or by calling 901. The Ministry of Interior also runs a national eCrime reporting service, and in Abu Dhabi the Aman service (8002626) is available. [Verify these channels are current on the day of publishing.]
- If you are a business, consider whether personal data was exposed and speak to a legal adviser or your data-protection lead about notification obligations.
- Get a professional review. Ask a qualified installer or security consultant to check that no backdoor, unknown user or hidden configuration remains.

How to choose a secure CCTV system and installer
Ask these questions before you buy or sign off an installation:
- Does the manufacturer publish security advisories and provide regular firmware updates for the models I am buying?
- Does the system force a new password during setup, and support 2FA and HTTPS?
- Will the installer put the cameras on a separate network and avoid port forwarding?
- Will I receive documentation: device list, firmware versions, accounts, network diagram?
- Is the installer SIRA-approved, and do they provide ongoing support and maintenance?
- Who holds the admin passwords, and will they be handed over to me?

Common myths about CCTV hacking
- “My system is small, so nobody would target it.” Most attacks are automated and scan the internet for any vulnerable device. Size does not matter.
- “A strong password is enough.” Not if the firmware has a known flaw or the device is exposed to the internet.
- “Wireless cameras are always less safe than wired.” Not necessarily. A poorly secured wired system can be worse than a well-configured wireless one. But wired PoE reduces the Wi-Fi attack surface.
- “Expensive means secure.” Price does not guarantee security. Update policy, configuration and installation quality matter more.
- “Once installed, it’s done.” Security is ongoing: updates, account reviews and audits.
Ending Words
Most CCTV hacks are preventable. If you do only three things this week, change every default password, update your firmware, and stop exposing cameras to the internet. Then work through the rest of the checklist: separate networks, secure remote access, controlled user accounts, a locked recorder and an annual audit.
If you would like a professional to check your system, SEFA can review your cameras, recorder, network and accounts and recommend practical fixes.
