Fast Takeover
Quick assessment and takeover of existing systems with minimal disruption.
Existing Systems, Restored & Improved
Security System Takeovers & Upgrades
If your current security system is outdated, unsupported or installed by another provider, WESEC can take it over, upgrade it and bring it up to modern standards — without unnecessary replacement.
Upgrade, Not Replace
Compatible equipment is retained and improved instead of forcing full replacement.
Restore Access & Codes
Regain control of users, permissions and administration access where possible.
Existing System Problems
Problems We Commonly Fix
If your security system is no longer performing as it should, you are not alone. Many systems can be restored, supported or upgraded without starting again from scratch.
Installer Gone?
Your original installer is no longer trading, responding or providing support, leaving the system unmanaged and difficult to maintain.
System Outdated?
The equipment still works, but it is slow, unsupported, unreliable or no longer meets your current security and operational needs.
No Access or Codes?
You have inherited a system but do not have administrator access, user codes, documentation or full control of the equipment.
Clear Takeover Process
Our Takeover Process
A clear, structured approach to taking control of existing security systems while retaining compatible equipment wherever practical.
System Assessment
We inspect the existing security system to understand its condition, configuration, performance and current limitations.
Compatibility & Options
We identify what can be retained, repaired, upgraded or improved, helping avoid unnecessary replacement costs.
Takeover & Optimisation
We take control of the system, improve its configuration, apply approved upgrades and resolve issues found during the assessment.
Handover & Support
You regain full access to a verified, working system with clear documentation and options for ongoing maintenance and support.
Existing Security Systems
Systems We Can Take Over
We work with a wide range of existing security systems installed by other providers, including standalone and integrated installations.
CCTV
Existing analogue or IP CCTV systems, including recorder upgrades, camera replacements, storage improvements and configuration changes.
Intruder Alarms
Wired, wireless and hybrid alarm systems taken over, recommissioned, reprogrammed and upgraded where required.
Access Control
Standalone or networked access systems, including fobs, cards, keypads, readers, locks, controllers and user permissions.
Intercoms
Audio and video intercom systems for residential or commercial properties, including older and legacy installations.
Smarter Upgrade Decisions
Takeover vs Full Replacement
Understanding the difference can save time, cost and unnecessary disruption. We assess what is already installed before recommending the right approach.
Takeover & Upgrade
Retain suitable equipment and improve what is already in place.
- Retains compatible existing equipment
- Lower cost than full replacement
- Minimal disruption to your site
- Faster return to full operation
- Suitable for phased improvements
- Focused on performance and reliability
Full Replacement
Remove the existing installation and replace the system completely.
- All equipment removed and replaced
- Higher upfront cost
- More disruption and downtime
- Longer installation timeframe
- Unnecessary when systems remain serviceable
- Sometimes required when equipment is unsupported
Improve What You Already Have
What We Can Upgrade
A takeover does not always mean replacing the entire system. We can improve selected parts of the installation to increase reliability, usability and performance.
CCTV Upgrades
Replace selected cameras, improve image quality, increase storage, add remote access or upgrade the recorder.
Intruder Alarm Upgrades
Add detectors, app control, new keypads, wireless devices, external sounders or improved communication modules.
Access Control Upgrades
Add users, readers, doors, schedules, remote management, event reporting or improved locking equipment.
Intercom Upgrades
Replace handsets, improve video quality, add mobile answering, improve door release or upgrade entrance panels.
Network & Remote Access
Improve poor connections, replace unstable wireless links and restore reliable remote access, notifications and app control.
Power & Backup
Replace weak batteries, power supplies and backup equipment that may be causing intermittent faults or system warnings.
System Restored and Supported Access, configuration and reliability brought back under control.
Before & After Takeover
From Unmanaged to Fully Supported
A takeover gives you back control of the system. We assess what is already installed, identify the main risks and return the equipment to a documented, supportable condition wherever possible.
Before Takeover
- Missing codes or admin access
- Unknown users, fobs or permissions
- Faults left unresolved
- Outdated or incorrect settings
- No reliable ongoing support
- Poor or missing documentation
After Takeover
- Access restored where possible
- Users and permissions reviewed
- Faults identified and explained
- Configuration improved
- Ongoing maintenance available
- Important system details documented
The result is a clearer, more reliable system with defined ownership, documented access and a practical route for future support.
Regain System Control
Restore Access, Codes & Control
When a property changes ownership, staff leave or the original installer disappears, administrative access can be lost. WESEC can assess the system and restore control where the equipment and manufacturer restrictions allow.
We review who currently has access, remove obsolete users where possible and help establish clear ownership of important system credentials.
Ownership and Security Checks Apply
Access restoration depends on the equipment, available credentials, proof of authorised ownership and any manufacturer security restrictions.
Reset User Codes
Old or unknown user codes can be reviewed, replaced or removed where the system allows.
Review Administrator Access
Engineer, manager and administrator access is checked and updated where possible.
Remove Old Users & Fobs
Former staff, tenants, contractors or unknown credentials can be removed from supported systems.
Add New Users & Permissions
New users, schedules, access levels and permissions can be configured to suit the property.
Reconnect Mobile Apps
Remote access, notifications and app control can be restored or transferred where supported.
Document Important Credentials
Key access details and system information can be recorded for authorised future use.
Honest Replacement Advice
When Replacement May Be the Better Option
We aim to retain compatible equipment wherever practical, but some systems are no longer safe, reliable or economical to support.
Equipment Is Discontinued
Key system components are no longer manufactured or supported by the original manufacturer.
Parts Are Unavailable
Replacement modules, batteries, readers, cameras or control equipment can no longer be sourced reliably.
System Is Severely Damaged
Water ingress, corrosion, fire damage, vandalism or widespread equipment failure makes repair unreliable.
Existing Cabling Is Unsuitable
Damaged, unstable or incompatible cabling prevents the system from operating reliably or supporting upgrades.
Security Risks Cannot Be Corrected
The system has unsupported software, insecure access or limitations that cannot be resolved safely.
System Cannot Meet Current Needs
The installation cannot provide the required coverage, access control, reporting, app access or reliability.
Repair Cost Is Too High
Repeated faults or major repairs would cost close to the price of a modern replacement system.
Manufacturer Support Has Ended
Software, cloud services or technical support required for continued operation are no longer available.
Planned Upgrade Stages
Upgrade Without Disrupting the Whole Site
Large or complex security systems do not always need to be upgraded all at once. WESEC can divide the work into practical phases, keeping important areas operational while priority improvements are completed.
This approach can help spread costs, reduce downtime and allow the most urgent faults or security risks to be resolved first.
Priority-led improvements
Safety, reliability and operational impact are considered when deciding which parts of the system should be upgraded first.
Discuss a Phased Upgrade
Resolve Critical Faults First
Failed equipment, security gaps, unstable power and urgent access problems are prioritised before less critical improvements.
Upgrade Core Equipment
Recorders, control panels, servers, controllers or other central equipment can be upgraded while retaining compatible field devices.
Improve Priority Areas
Important entrances, high-risk rooms, external areas or poorly covered zones can be addressed before secondary locations.
Complete Remaining Improvements
Additional devices, user features, documentation and final system optimisation can be completed as later phases.
Common phased upgrade examples
Recorder first, cameras later Priority doors before secondary doors External coverage before internal areas Alarm devices replaced in stages Work scheduled around business hours

Frequently Asked Questions
Security System Takeover FAQs
Answers to common questions about taking over, restoring and upgrading security systems installed by other providers.
Can you take over a system installed by another company?
Yes. We can assess CCTV, intruder alarm, access control and intercom systems installed by other providers. The takeover options depend on the equipment condition, available access and whether the system is still supported.
Will all existing equipment need to be replaced?
Not necessarily. We aim to retain equipment that remains compatible, safe and reliable. Replacement is recommended only where devices are faulty, unsupported, insecure or unable to provide the required performance.
Can you recover lost engineer or administrator codes?
In many cases, access can be restored by authorised reset, reprogramming or replacement of a control component. This depends on the manufacturer, system model, available credentials and proof that you are authorised to control the system.
Can you remove previous users, fobs or mobile access?
Yes, where supported. We can review existing users, remove obsolete credentials, add new users and update permissions, schedules or mobile access arrangements.
Can an old CCTV system be upgraded without replacing every camera?
Often, yes. Depending on compatibility, it may be possible to upgrade the recorder, storage, network connection or selected cameras while keeping other working equipment in place.
Can you add app access or remote viewing?
Where the existing system supports it, we can help restore or configure mobile apps, remote viewing and notifications. Older systems may require an approved communication module or recorder upgrade.
What happens if the existing equipment is discontinued?
We will explain which parts can still be supported and whether repairs remain practical. Where replacement is necessary, we provide clear reasons and look for opportunities to retain suitable cabling or compatible equipment.
Can the takeover or upgrade be completed in stages?
Yes. Larger systems can often be divided into practical phases. Critical faults and high-priority areas can be addressed first, with additional upgrades completed later to reduce disruption and spread costs.
Will I receive system information after the takeover?
We can document important equipment details, agreed user access and the work completed. The exact documentation provided depends on the system and the scope of the takeover.
Can WESEC maintain the system after taking it over?
Yes. We offer ongoing maintenance, fault call-outs, battery replacement, configuration changes and future upgrades for suitable systems after takeover.
