4G Intercom Maintenance & Repair
Regular maintenance of your 4G intercom system is essential to ensure ongoing reliability, security, and performance.

Hardware Checks
We inspect all intercom hardware to make sure everything’s working as it should. That includes checking call buttons, speakers, cameras, keypads, and power connections. If we spot wear or damage, we’ll fix it before it causes problems.
Inspect and clean camera lenses for clear image quality
Test call buttons, microphones, and speakers for clarity and responsiveness
Check screen functionality
Inspect enclosure and mounting for weather damage or tampering
Ensure secure wiring for any connected devices (e.g. electric locks, gates)
Confirm SIM card signal strength and carrier performance
Software & Connectivity
We check that your system’s software is up to date and running smoothly. That includes testing the 4G signal, app connectivity, user access settings, and any linked devices. If there are issues, we’ll sort them to keep everything connected and secure.
Test live video and audio calls through the app
Verify remote unlock functions are working correctly
Confirm access codes, fob readers, or keypads are operational
Check and update firmware where required
Review cloud portal for logs, alerts, or errors
Back up system settings where applicable
User & Access Management
We review who has access to your system and make sure all user data is current. That includes adding or removing residents, updating key fobs or codes, and checking permissions. It keeps your system secure and easy to manage.
Assist with adding or removing users via the cloud portal
Check expiry settings for virtual keys or QR access codes
Provide guidance to property managers on usage and best practices
Ensure compliance with data protection and system security protocols
Ongoing Support & Reporting
After each visit, we provide a maintenance report summarising the checks carried out, any issues found, and actions taken or recommended. We also offer remote monitoring options and support packages for managing agents, landlords, and developers. Whether your system was installed by us or not, we can provide full-service maintenance to keep it running smoothly.

Our Installs vs Others
There’s a clear difference between repairing systems we’ve installed and those fitted by other companies. When it’s our work, we’re already familiar with the setup, so we can get things sorted quickly. For systems installed by others, we’re still happy to help. We’ll take the time to understand how it’s set up, carry out a thorough assessment, and do our best to get it working as it should.
If We Installed Your System
If the 4G intercom was installed by us, please contact us via your managing agent or property manager. Once we receive a request from them, we can:
Remotely access the system via the cloud management portal
Diagnose and resolve issues without a site visit where possible
If a physical inspection is needed, we will arrange a site visit as soon as possible
If the System Was Installed by Another Company
If we did not originally install your system, we can still help. Please have your property manager or managing agent get in touch with us directly. In order to carry out diagnostics, we will require:
Access to the system’s cloud management portal
Any relevant documentation or previous service history (if available)
Once we have access, we will assess the fault remotely. If a site visit is required, we will arrange this promptly to minimise downtime.
