Intercom Repairs in Melbourne for Hikvision, Dahua, Aiphone & Urmet Systems
SIPKO Security provides intercom repairs in Melbourne for existing residential intercom systems — diagnosis, fault finding, component repair and replacement for houses, townhouses and other individual residential properties.
Repair starts with finding where the fault actually is — not replacing the whole system by default. SIPKO traces a fault back to its actual cause before recommending a repair, a component replacement, or a wider upgrade.
SIPKO diagnoses and repairs existing intercom systems built on Hikvision, Dahua, Aiphone and Urmet, matching the repair approach to the brand, model and condition of the equipment already installed.
- Intercom not ringing
- No audio
- No video
- Indoor monitor or handset fault
- Door station fault
- Door or gate not releasing
- Intermittent faults
- App or network connectivity issues
Brands serviced: Hikvision · Dahua · Aiphone · Urmet, across Melbourne and the Mornington Peninsula.
What Actually Fails in an Intercom System?
Before a repair can be recommended, it helps to separate an intercom into the parts that can actually fail — because the same symptom can come from more than one of them.
A door station sits at the entry point and handles the call and, on video systems, the camera. Cabling or a network connection carries that call back into the property. Power and a controller keep the system running and handle door or gate release. On the inside, an indoor monitor, handset or mobile app is where the resident actually answers. Any one of these can fail on its own, and a fault in one part — a loose connection, a power issue, a configuration change — can show up as a symptom in a completely different part of the system.
That’s why SIPKO’s process follows the same sequence every time: identify the symptom, isolate which part of the system is actually responsible, test that part specifically, repair or replace what’s failed, then retest the complete intercom — call, audio, video, answering and release — before calling the job done.
Common Intercom Faults SIPKO Diagnoses
Every symptom below can have more than one cause — the fault is confirmed during diagnosis, not assumed from the symptom alone.
- Intercom not ringing
- Can point to the call button, wiring, programming, power, or the indoor monitor, handset or app that’s meant to receive the call.
- No audio
- Often traced to the microphone or speaker at the door station, cabling, or the audio configuration of the indoor device.
- No video
- Checked against the door station camera, the indoor monitor or app, and the network or cabling carrying the video signal.
- Indoor monitor or handset failure
- A monitor or handset that’s unresponsive, frozen or won’t power on, which may or may not indicate the rest of the system is affected.
- Door station problems
- Physical damage, weather ingress, a failed camera or call module, or a door station that’s no longer communicating with the rest of the system.
- Door or gate won’t release
- Investigated at the relay output, the electric strike, lock or gate controller, and the wiring connecting them.
- App or network connection problems
- Relevant to IP-based systems, where the fault may sit with the network connection, app configuration, or the device itself.
- Intermittent faults
- Faults that come and go are usually the hardest to pin down, and can be caused by a connection, power or configuration issue as well as by the device itself.
No audio, for example, isn’t automatically a failed microphone or speaker. On Hikvision video intercom systems, a door station added to an NVR or recorder can lose one-way audio simply because the encoder stream isn’t configured to carry both video and audio, and mismatched firmware between older and newer intercom units on the same system has caused similar one-way audio faults. Confirming the configuration and firmware alongside the physical hardware is part of SIPKO’s diagnosis on Hikvision systems, rather than assuming a faulty component from the symptom alone.
How Intercom Fault Finding Works
SIPKO doesn’t move from symptom straight to a replacement recommendation. Each symptom is traced through the parts of the system that could actually be responsible.
| Symptom | What SIPKO checks |
|---|---|
| No ring | Call button, programming, wiring, indoor monitor or handset |
| No audio | Microphone, speaker, cabling, device configuration |
| No video | Camera, monitor or app, network/cabling, power |
| No door or gate release | Relay output, lock/strike or gate controller, wiring |
| Dead system | Power supply, cabling, controller and connected devices |
| App offline | Network connection, app configuration, device status |
The point of this step An intercom fault is traced and isolated before a repair or replacement is recommended — symptom, trace, isolate, repair, rather than symptom, guess, replace.
Hikvision, Dahua, Aiphone & Urmet Intercom Repairs
SIPKO diagnoses and repairs existing residential intercom systems across four platforms. What’s repairable, and how, depends on the specific model, its age and condition — confirmed during diagnosis rather than assumed from the brand alone.
Hikvision
Diagnosis and repair for existing Hikvision villa and IP intercom systems, including door station, indoor monitor, Hik-Connect app and network connectivity faults.
Hikvision intercom service & repairs →Dahua
Fault finding and repair for existing Dahua Villa Solution and 2-wire intercom systems, covering door stations, indoor monitors and DMSS app connectivity.
Dahua intercom repair & installation →Aiphone
Diagnosis and repair for existing Aiphone intercom systems. Many older Aiphone residential installations run on dedicated wiring straight from the master station rather than a shared network, so confirming the wiring and the master station’s capacity is part of the diagnosis before any component is repaired or replaced.
Aiphone intercom repair →Urmet
Diagnosis and repair for existing Urmet systems, from 2-wire installations through to older multi-conductor systems. Because the wiring generation varies with the age of the installation, confirming which type is in place at the property is one of the first steps in diagnosing an Urmet fault.
SIPKO doesn’t claim to repair every model of every system. Where parts are discontinued or a fault sits beyond what a repair can reasonably fix, that’s explained as part of the diagnosis, alongside the replacement or upgrade options available.
Repair the Existing Intercom, or Replace It?
Neither option is the default. Which one makes sense depends on what the diagnosis actually finds.
Repair may make sense when:
- The fault has been isolated to a specific part
- The rest of the system is working normally
- The failed component can be serviced or replaced on its own
- The existing wiring and infrastructure are sound
- Compatible parts are available for the model
Replacement or upgrade may be more appropriate when:
- Parts are unavailable or discontinued
- Multiple components are failing at once
- The same fault keeps recurring after repair
- Existing infrastructure is damaged or incompatible
- Repair cost no longer makes sense against the condition of the whole system
The final recommendation is only made after diagnosis. Where replacement turns out to be the more sensible path, see intercom installation in Melbourne for how SIPKO plans a new system around the property.
Existing Wiring Is Part of the Diagnosis
A fault that looks like a failed device is sometimes actually a wiring or power problem. SIPKO checks the existing wiring as a normal step in diagnosis, not only when a device has already been ruled out.
- Loose or corroded connections
- Damaged or deteriorated cable
- Poor terminations
- Power supply issues
- Network faults on IP-based systems
- Cable route and general condition
- Compatibility with the installed equipment
On 2-wire systems such as Dahua’s Villa Solution, the door station and indoor monitor share both power and data across the same pair, fed through a dedicated 2-wire switch or power supply with a defined maximum cable run. A loose connection or a run pushed past that limit can affect power and communication at the same time, which is one reason a fault that looks like a failed device can actually be sitting in the cable.
How SIPKO Diagnoses and Repairs an Intercom
Identify the symptom
Confirming exactly what’s stopped working, and when it started.
Inspect the existing system
Reviewing the brand, equipment, wiring and general condition of the installation.
Trace the fault
Following the relevant signal, power or network path through the system.
Isolate the failed point
Narrowing the fault down to a device, connection, wiring segment or configuration issue.
Explain the repair options
Setting out what can be repaired, what needs replacing, and what a wider upgrade would involve.
Repair or replace the failed component
Carried out once the cause is confirmed, not before.
Retest the complete system
Confirming calling, audio, video, answering and door/gate release all work correctly before handover.

Intercom Repair Melbourne FAQ
What intercom brands do you repair?
Can older Aiphone or Urmet intercoms still be repaired?
Why has my intercom stopped ringing?
Can an old intercom be repaired instead of replaced?
Can existing intercom wiring cause the fault?
Can you repair an intercom without replacing the whole system?
What information should I provide before an intercom repair visit?
Can you diagnose an intermittent intercom fault?
Tell SIPKO what the intercom is doing — or not doing — and, if known, the brand and model. SIPKO can inspect the existing system, identify the fault and explain whether a repair, a component replacement, or a wider upgrade is the appropriate next step.
Request a diagnosis. Cost depends on factors including: the fault itself, the brand and model, access to wiring and equipment, parts required, and whether a full system upgrade is more appropriate than a repair.
