Why Are CCTV Systems Increasingly Targeted?

As CCTV systems have become more connected and increasingly dependent on software, apps and remote access, they have also become more attractive to cybercriminals.

Many organisations assume the main risk is somebody viewing their cameras. In reality, the potential consequences are much broader:

• Unauthorised access to live footage
• Theft or unauthorised disclosure of recorded video
• Disruption to cameras, recorders or monitoring
• Loss or corruption of evidential footage
• Privacy and UK GDPR concerns
• Unauthorised changes to system settings or accounts
• Compromised devices being used in wider cyberattacks
• A vulnerable CCTV device providing a route towards other networked systems

Modern CCTV should therefore be treated with the same care as other network-connected technology.

A Modern CCTV System Is No Longer Just a Camera System

CCTV has evolved from standalone analogue recorders into fully networked video surveillance platforms. A modern installation may include:

• IP cameras
• Network video recorders (NVRs)
• Video management software (VMS)
• Remote-access applications
• Mobile viewing
• Cloud services
• AI-powered video analytics
• Access control integration
• Intruder alarm integration

As a result, a CCTV recorder is often more comparable to a server than a traditional video recorder. Installing it and leaving it unchanged for the next ten years is no longer an appropriate approach.

Modern CCTV systems require ongoing software and firmware management, user administration, access reviews and cybersecurity checks.

The Most Common CCTV Cybersecurity Issues We Find

When taking over existing systems, the most significant weaknesses are often surprisingly straightforward.

Outdated Firmware

One of the most common issues is outdated firmware. Manufacturers release updates to address security vulnerabilities, correct software defects, improve stability and maintain compatibility. A CCTV system may continue recording normally while running outdated software containing known vulnerabilities.

Shared Administrator Accounts

It is not unusual to find one administrator account used by several people, generic usernames or passwords that have been passed between staff and contractors for years.

When several people use the same credentials, accountability is lost. It becomes difficult to establish who viewed footage, changed settings, exported recordings or altered user permissions.

Legacy Remote Access

Older CCTV systems often relied on direct internet exposure and port forwarding for remote viewing. These arrangements can create unnecessary risk if they are poorly configured or left unmanaged.

Remote-access methods established years ago should not be assumed to remain suitable or secure today.

Unnecessary Services and Poor Network Configuration

Unused services, open ports, unrestricted device communication and flat network design can all increase exposure. Only the services and connections needed for the CCTV system’s operation should be enabled.

Real-World Example: Who Actually Has Access to Your CCTV?

One of the first tasks we carry out when taking over an existing CCTV system is reviewing its user accounts and remote-access permissions.

We regularly find a single administrator account used by several parties, which may include:

• The customer
• Facilities personnel
• IT staff
• Previous installers
• Current and former contractors

Over time, the password may have been shared repeatedly without any reliable record of who knows it. In some cases, previous installers have retained access years after the original work was completed.

The organisation may believe it has exclusive control of its CCTV system when the actual position is very different.

The Shared Password Problem

When everybody uses the same administrator account:

• Accountability disappears
• Audit trails lose much of their value
• Password changes become difficult to coordinate
• Former employees may retain the credentials
• Previous contractors may still have access
• Security incidents become harder to investigate

Our Approach

When taking over a system, we review:

• User accounts
• Administrator permissions
• Password arrangements
• Remote-access settings
• Historic installer and contractor access

Redundant access can then be removed and credentials changed where appropriate. We strongly recommend an individual account for every person who requires access.

Why Individual CCTV User Accounts Matter

Separate accounts provide:

• Clearer accountability
• More useful audit trails
• Role-based permissions
• Easier user management
• Faster removal of former employees and contractors
• Better visibility of system activity

Users should only receive the permissions they need. Routine users should not be given administrator rights simply for convenience.

The Biggest CCTV Cybersecurity Misconceptions

“It’s Only Cameras. Nobody Wants to Hack Them.”

The risk is not limited to somebody wanting to watch live footage. An insecure CCTV recorder or camera may be disrupted, recruited into a botnet or used as a route into a wider network.

“We’re Too Small to Be Targeted.”

Many cyberattacks are opportunistic and automated. An exposed device with weak credentials or outdated firmware may be discovered regardless of whether it belongs to a small business, school, warehouse, retailer or major organisation.

What Does a Secure CCTV Installation Look Like?

Firmware and Security Update Management

Firmware status should be checked during commissioning and then reviewed throughout the system’s working life. Updates should be obtained from trusted manufacturer sources, assessed for relevance and installed through a controlled process.

Strong Password Management

Default credentials must not remain in use. Accounts should use strong, unique passwords, and administrative access should be tightly controlled. CCTV passwords should not be reused across other business systems.

Multi-Factor Authentication

Where the platform supports it, multi-factor authentication (MFA) should be enabled, particularly for remote and administrative access. MFA adds another verification step and reduces the risk created by a stolen or compromised password.

Individual Accounts and Role-Based Permissions

Every authorised user should have an individual account with permissions appropriate to their role. If somebody leaves the organisation or no longer needs access, their account can be disabled without disrupting other users.

Network Segregation

Where appropriate, CCTV devices should be separated from the wider business network using VLANs, firewall rules or other suitable controls. Segregation can restrict unnecessary communication, limit exposure and reduce the effect of a compromised device.

Controlled Remote Access

Remote viewing is useful, but convenience should not come at the expense of security. Direct exposure and unnecessary port forwarding should be avoided where a more secure, supported method is available.

Remote access should be documented, limited to authorised users and reviewed regularly.

Secure Handover

Following handover, access arrangements should be clearly documented and agreed with the customer. I Security only retains access where there is a defined support requirement and the customer’s explicit agreement.

CCTV Systems and Cyber Essentials

Cyber Essentials is a UK Government-backed scheme built around five technical controls: firewalls, secure configuration, security update management, user access control and malware protection.

Although Cyber Essentials is not a CCTV-specific certification, network-connected cameras, recorders and management devices should not be overlooked when an organisation defines and protects its IT infrastructure.

Relevant considerations may include:

• Removing default accounts and passwords
• Applying supported security updates
• Disabling unnecessary services
• Restricting administrative privileges
• Using firewalls and secure network configuration
• Reviewing externally accessible services

The exact certification scope should be confirmed with the organisation’s IT team or Cyber Essentials assessor.

CCTV Cybersecurity, Privacy and UK GDPR

Recorded CCTV images may constitute personal data. Protecting footage is therefore not just an equipment issue; it forms part of the organisation’s wider data-protection responsibilities.

Appropriate measures may include:

• Restricting footage to authorised users
• Documenting who has access and why
• Protecting exported recordings
• Setting appropriate retention periods
• Maintaining useful audit records
• Reviewing remote and third-party access
• Responding appropriately to suspected data breaches

An organisation should also ensure that its signage, policies, lawful basis, retention practices and handling of access requests are appropriate for its use of video surveillance.

Manufacturer Security Features Still Need Correct Configuration

Modern professional CCTV platforms may provide security functions such as encrypted communications, role-based permissions, account lockout, audit logs, signed firmware, secure remote access and MFA.

Availability varies by manufacturer, model, software version and platform. These features only protect the system when they are supported, enabled, configured correctly and maintained.

What We Check When Taking Over an Existing CCTV System

• Firmware and software versions
• Manufacturer support status
• User account structure
• Administrator permissions
• Password management
• MFA availability and configuration
• Remote-access configuration
• Network exposure and open services
• Port-forwarding rules
• Recording health and evidential export
• Storage capacity and retention
• Audit logs
• Network segregation
• Time synchronisation
• Historic installer and contractor access

In our experience, user accounts and remote-access permissions are often among the areas presenting the greatest avoidable risk.

CCTV Cybersecurity in Schools

Schools increasingly rely on CCTV to support safeguarding, student and staff safety, incident investigation, visitor management and asset protection.

Educational environments can also create particular access-management challenges, including:

• Several administrators or sites
• Shared operational responsibilities
• Changes in staff and contractors
• Links with IT support providers
• Footage involving children and other vulnerable individuals

Clear permissions, documented responsibilities, controlled exporting and regular access reviews are essential. Safeguarding responsibility should not lead to unnecessarily broad access to live or recorded footage.

Questions Every CCTV Owner Should Ask

• Who currently has administrator access?
• Does the current or previous installer retain access?
• When was the firmware last reviewed?
• Are any users sharing passwords?
• Does every user have an individual account?
• Is MFA enabled where available?
• How is remote access provided and controlled?
• Is the CCTV network segregated where appropriate?
• Could former staff or contractors still log in?
• Are audit logs available and regularly reviewed?
• Is there a documented process for exporting and sharing footage?

If these questions cannot be answered confidently, it may be time for a structured CCTV cybersecurity review.

Expert Advice: A Cyberattack May Not Be About Your Footage

When people think about CCTV hacking, they often imagine somebody accessing live cameras or stealing recordings. Those are genuine concerns, but they are not the only possible objectives.

A vulnerable camera or recorder may be targeted as another internet-connected endpoint. It could be used in a botnet, disrupted, or potentially exploited in an attempt to move towards other systems.

This is why firmware management, strong authentication, controlled remote access and network segregation matter even where the footage itself appears unlikely to interest an attacker.

Frequently Asked Questions

Can CCTV cameras be hacked?

Yes. Risk increases where devices use weak or reused passwords, outdated firmware, unnecessary internet exposure or poorly controlled remote access.

How often should CCTV firmware be updated?

Firmware should be reviewed regularly and when the manufacturer publishes relevant security information. Updates should be assessed and installed through a controlled process rather than applied without considering compatibility and operational risk.

Can a previous installer still access my CCTV system?

Potentially. Historic installer accounts, shared passwords or remote-access arrangements may remain active until they are checked and removed.

Does CCTV need to be considered for Cyber Essentials?

Network-connected CCTV equipment should not automatically be ignored. Whether particular cameras, recorders or supporting devices fall within an organisation’s certification scope should be confirmed with its IT team or Cyber Essentials assessor.

Is remote CCTV viewing secure?

It can be secure when supported methods, strong authentication, appropriate encryption and controlled user permissions are used. Remote access should be documented and reviewed regularly.

Should CCTV be on a separate network?

Segregation is often advisable, particularly in larger or higher-risk environments. The appropriate design depends on the system, operational requirements and wider network architecture.

Should my CCTV system use MFA?

Where MFA is supported, it should normally be enabled for remote and privileged accounts as an additional defence against compromised passwords.

Final Thoughts

One of the biggest CCTV cybersecurity risks is not always a sophisticated attacker. It is an organisation not knowing who already has access to its system.

The most common weaknesses include outdated firmware, shared administrator accounts, uncontrolled remote access, poor password management, excessive privileges and insufficient network segregation.

The most secure system is not necessarily the one with the newest cameras. It is the one where:

• Firmware is actively maintained
• Access is controlled and documented
• Users have individual accounts
• MFA is enabled where supported
• Remote access is reviewed regularly
• Customers know exactly who can access their system

Cybersecurity is not just about protecting footage. It is about ensuring the CCTV system does not become the weakest point in the organisation’s wider security strategy.
