Professional Security System Repairs, Fault Finding & Maintenance

When a security system stops working properly, you need more than someone who can replace a component.

You need someone who can identify the cause of the problem, understand how the system is designed and recommend the most practical way to get it operating reliably again.

Cadence Systems provides professional security system repairs, fault finding, upgrades and maintenance throughout Toowoomba and the Darling Downs.

We work on a wide range of existing systems including:

  • CCTV

  • Intruder alarms

  • Access control

  • Intercom systems

  • Data networks

  • Wi-Fi

  • Communications infrastructure

Whether your CCTV cameras have stopped recording, your alarm is generating faults, an access-controlled door isn't unlocking correctly or an intercom has become unreliable, we can assess the system and determine the most appropriate repair or upgrade path.

You do not need to have had the system originally installed by Cadence Systems.

We can inspect and troubleshoot many existing installations, including ageing systems, poorly documented sites and equipment installed by previous contractors.

Our focus is on providing practical advice. Where repairing the existing system makes sense, we'll repair it. Where equipment has become obsolete, unreliable or uneconomical to maintain, we'll explain the available upgrade options.

- Frequently Asked Questions

Can you repair a security system you didn't install?

> Yes. We can inspect and troubleshoot many systems originally installed by other contractors. Whether repair is possible will depend on the equipment, system condition and availability of replacement parts.

Do I need to replace my entire CCTV system if one camera fails?

> Usually not. A single camera failure may be caused by the camera itself, cabling, network equipment, power or configuration. We'll identify the fault before recommending replacement.

Why has my CCTV stopped recording?

> Common causes include failed hard drives, incorrect recording settings, recorder faults or storage problems. It is important to check recording regularly because a system can still display live video even when recordings aren't being saved.

Why does my alarm keep going off?

> False alarms can be caused by faulty detectors, environmental conditions, damaged contacts, low batteries or incorrect configuration. The system should be inspected rather than simply disabling the affected zone.

Can you repair an old alarm system?

> Often, yes. However, very old systems may have limited spare-part availability or unsupported communications technology. We'll advise whether repair or replacement makes more sense.

Can you service access control systems?

> Yes. We can investigate reader, controller, locking, power supply and door monitoring faults on many access control systems.

Can you repair intercom systems?

> Yes. We can troubleshoot many audio, video, door release, network and power-related intercom faults. are recordings stored?

Can you upgrade my existing system instead of replacing everything?

> Often. Where cabling and other infrastructure remain suitable, it may be possible to upgrade key components while retaining parts of the existing installation.

How often should security systems be serviced?

> It depends on the type of system, environment and how critical the installation is. Commercial systems generally benefit from periodic inspection rather than waiting until a fault occurs.

Do you provide ongoing maintenance?

> Yes. We can provide scheduled security system maintenance for commercial and larger residential installations depending on the requirements of the site.

Security System Repairs

Faults Diagnosed Properly

Security systems can fail for many reasons.

Sometimes the problem is obvious, such as a failed camera or damaged detector.

Other faults can be caused by:

  • Cabling problems

  • Network issues

  • Power supply faults

  • Failed hard drives

  • Batteries

  • Configuration changes

  • Ageing equipment

  • Communications problems

  • Software or firmware issues

  • Environmental damage

  • Previous poor workmanship

Replacing equipment without identifying the underlying cause can waste time and money.

We take a systematic approach to troubleshooting so the actual fault can be identified before unnecessary components are replaced.

CCTV Repairs & Maintenance

Get Your Cameras Recording Properly Again

CCTV systems often continue operating with faults that aren't immediately obvious.

A camera may be offline, recording may have stopped, storage may have failed or remote viewing may no longer work.

Common CCTV problems include:

  • Cameras offline

  • No recorded footage

  • Failed hard drives

  • Poor image quality

  • Blurry or dirty cameras

  • Night vision problems

  • Remote viewing not working

  • Mobile app connection problems

  • Recorder faults

  • Network faults

  • PoE switch problems

  • Damaged cabling

  • Intermittent camera connections

  • Incorrect time or recording settings

Cadence Systems can inspect the complete CCTV system, including cameras, recorders, cabling, network infrastructure and remote access.

Where possible, we can repair or reconfigure the existing installation before recommending replacement.

CCTV System Health Checks

A CCTV system can appear to be working while still failing to record useful footage.

Regular checks can identify problems before an incident occurs.

A CCTV maintenance inspection may include:

  • Camera operation

  • Image quality

  • Camera focus and positioning

  • Night-time performance

  • Recorder status

  • Recording schedules

  • Hard drive health

  • Date and time configuration

  • Remote access

  • Network connectivity

  • Power supplies

  • UPS condition

  • Physical camera condition

This is particularly important for businesses relying on CCTV for incident investigation, workplace safety or asset protection.

Alarm System Repairs

False Alarms, Faults & System Problems

An unreliable alarm system quickly becomes frustrating.

Repeated false alarms can result in users ignoring genuine alerts, while communication and battery faults may reduce the effectiveness of the system without being immediately obvious.

We can assist with issues including:

  • Alarm system won't arm

  • Fault indicators

  • False alarms

  • Failed detectors

  • Door contact faults

  • Low battery warnings

  • Siren problems

  • Keypad faults

  • Communication failures

  • Smartphone app issues

  • Forgotten or incorrect codes

  • Zone faults

  • Intermittent problems

We can also assess older systems and advise whether repair, partial upgrade or replacement represents the best value.

Alarm System Maintenance

Alarm systems contain components that require periodic inspection and replacement.

Battery condition is particularly important because the system relies on backup power during a mains power failure.

Maintenance may include:

  • System fault checks

  • Detector testing

  • Battery testing

  • Siren testing

  • Communication testing

  • Door contact testing

  • User code review

  • App connectivity

  • Control panel inspection

  • Event history review

Regular maintenance helps identify ageing components before they cause system failures.

Access Control Repairs

Doors That Don't Unlock, Lock or Report Correctly

Access control faults can affect both security and normal business operation.

Problems may involve the electronic security system, door hardware, cabling or power supplies.

Common issues include:

  • Card readers not responding

  • Credentials not working

  • Doors not unlocking

  • Doors remaining unlocked

  • Electric strike faults

  • Magnetic lock problems

  • Request-to-exit device faults

  • Door contacts reporting incorrectly

  • Controller communication faults

  • Power supply failures

  • Access control software issues

  • User permission problems

Because access control involves both electronic security and physical door operation, effective troubleshooting requires understanding how the complete system works together.

Access Control Maintenance

Commercial access control systems should be inspected periodically, particularly where doors are heavily used.

Maintenance can include:

  • Reader testing

  • Door lock operation

  • Door contact testing

  • Emergency release checks

  • Controller status

  • Power supply inspection

  • Battery condition

  • User database review

  • Event log inspection

  • Communications testing

Preventative maintenance can help identify worn components before a door becomes unreliable or fails completely.

Intercom Repairs

Restore Reliable Visitor Communication

Intercom systems often remain in service for many years and can develop problems as components age.

We can investigate issues including:

  • No audio

  • Poor audio quality

  • No video

  • Door station faults

  • Indoor monitor faults

  • Door release not working

  • Calls not reaching residents

  • Network communication faults

  • Smartphone app problems

  • Power supply failures

  • Cabling faults

Where an older intercom system is no longer economically repairable, we can advise on replacement options and assess whether any existing cabling or infrastructure can be reused.

Apartment & Multi-Tenant Intercom Faults

Apartment intercom systems can be more complex than residential installations because they may involve:
  • Multiple apartments

  • Building entrances

  • Door access

  • Lift control

  • Concierge stations

  • Network equipment

  • Resident databases

A fault affecting only one apartment may have a completely different cause from a fault affecting the entire building.

Cadence Systems can assess the installation and determine whether the issue relates to the apartment equipment, building infrastructure or central system.

Network & Wi-Fi Fault Finding

Modern security systems depend heavily on IP networks.

A CCTV, intercom or access control fault may actually be caused by the underlying network rather than the security equipment itself.

We can troubleshoot:

  • Network switches

  • PoE faults

  • IP addressing

  • Wi-Fi connectivity

  • VLAN configuration

  • Wireless links

  • Network cabling

  • Fibre links

  • Router configuration

  • Remote access

  • Device communication

Our experience across both security and networking allows us to diagnose problems across the complete system rather than treating the network as somebody else's responsibility.

Security System Upgrades

Improve an Existing System Without Starting Again

A complete replacement isn't always necessary.

Many existing installations can be improved by replacing selected components while retaining usable cabling and infrastructure.

Possible upgrades include:

  • CCTV recorder replacement

  • Additional cameras

  • Higher-resolution cameras

  • Larger storage capacity

  • Smartphone connectivity

  • New alarm control equipment

  • New detectors

  • Wireless alarm expansion

  • New access control readers

  • Mobile credentials

  • Intercom replacement

  • Network switch upgrades

  • Communications rack improvements

  • UPS installation

We'll assess what you already have and recommend what is worth keeping.

Older & Obsolete Security Systems

Technology changes quickly, but security equipment often remains installed for many years.

Eventually, some systems become difficult to maintain because:

  • Replacement parts are unavailable

  • Software is unsupported

  • Mobile applications no longer function

  • Operating systems are incompatible

  • Manufacturers discontinue products

  • Equipment reliability deteriorates

Where this occurs, continuing to repair the system may no longer represent good value.

Cadence Systems can assess ageing systems and provide a staged upgrade plan where appropriate.

This may allow critical equipment to be replaced first while spreading other upgrades over time.

Preventative Security System Maintenance

Fix Problems Before They Become Failures

Preventative maintenance is particularly valuable for businesses where security systems form part of normal operations.

Rather than waiting for a complete system failure, regular maintenance can identify early warning signs such as:

  • Ageing batteries

  • Failing hard drives

  • Intermittent cameras

  • Unreliable locks

  • Faulty detectors

  • Poor network connections

  • Damaged cabling

  • Equipment overheating

  • Storage issues

Scheduled maintenance can reduce unexpected failures and help extend the useful life of the system.

Commercial Security Maintenance

We provide security system maintenance for:

  • Offices

  • Retail stores

  • Warehouses

  • Medical centres

  • Industrial facilities

  • Apartment buildings

  • Body corporate properties

  • Schools

  • Hospitality venues

  • Commercial properties

Maintenance arrangements can be tailored to the size and complexity of the installation.

For larger sites, keeping accurate information about system condition and ageing equipment can also make future budgeting and upgrades easier.

Security System Takeovers

Existing System, New Service Provider

You may have inherited a security system through:

  • Purchasing a property

  • Moving into a new tenancy

  • Changing security contractors

  • Taking over business premises

  • Buying an existing business

In many cases there may be little or no documentation about how the system is configured.

Cadence Systems can assess the existing installation and help establish what equipment is installed, how it operates and what may require attention.

Depending on the system, this may include:

  • Equipment identification

  • Basic system documentation

  • User management

  • Password and access review

  • Fault assessment

  • Network review

  • Maintenance recommendations

  • Upgrade planning

Poorly Installed or Untidy Systems

Unfortunately, not every security installation is completed to the same standard.

We regularly see issues such as:

  • Unlabelled cables

  • Unsupported cabling

  • Poor terminations

  • Untidy communications cabinets

  • Inadequate power supplies

  • Unprotected equipment

  • Poorly positioned devices

  • Incorrect network configuration

Where practical, we can rectify existing installation issues and improve the reliability and serviceability of the system.
