Looking to replace a tired old door buzzer or an ageing intercom without rewiring the house? The VIP Vision INTKIT-A1 is a simple, dependable analogue 4-wire / 4-core video intercom kit designed for Australian homes, units and small businesses. It uses the same style of 4-core alarm/communications cable many older systems were wired with, so most retrofits are a straight swap: re-use the cable, mount the new door station, power up the 7" monitor and you’re done. You get clear video, two-way talk and a proper door strike output for gates or front doors — no networking, no apps, no cloud, just a reliable hard-wired intercom that works every time.

Why installers and homeowners pick INTKIT-A1

• Runs on 4-core cable: perfect for replacing legacy intercoms and doorbells without pulling new Cat cable.
• Retrofit friendly: re-use existing cable runs and mounting locations, keeping labour and mess to a minimum.
• 7" indoor monitor: easy push-button operation for answer/hang-up, unlock, volume/brightness and cycling live views.
• Real door control: interfaces with most 12 V electronic door strikes and door sensors for secure entry.
• Expandable: supports up to three indoor monitors and an additional door station, so you can add the kitchen and master bedroom later.
• Optional extra camera (CVBS): add an analogue CCTV camera for live view from the monitor (e.g. driveway or shed).
• No internet required: works during home network outages and doesn’t rely on a phone app.

How it connects (simple 4-wire)

The kit uses a classic four-wire link between the door station and the indoor monitor for power, video and audio. For typical domestic runs up to ≈50 m, a standard 0.75 mm² 4-core cable is recommended. Longer runs can be achieved by using a coaxial feed for the video leg with the power/audio cores alongside. The included 12 V DC 2 A power supply is suited to a one door station + one monitor setup; if you add devices, match the PSU to the device count (e.g. 3 devices → 12 V 3 A).

Real-life uses around the home and business

• Front door upgrade: swap out an old chime so you can see and speak with visitors before you unlock.
• Granny flat or dual occupancy: run a monitor in the main residence and another in the granny flat for quick communication.
• Gate control: pair with a 12 V electric strike or gate relay to buzz in deliveries from the kitchen monitor.
• Shops & counters: keep the door locked while you verify visitors — ideal for chemists, jewellers and after-hours retail.
• Workshops & back-of-house: call through from the roller door or side access; add a second monitor in the office.
• Apartments & small blocks: retrofits nicely where there’s an existing 4-wire riser; simple, low-maintenance, no app training.

Fitting notes (quick install tips)

• Shelter the door station: mount under an eave or hood; seal around the cable entry to prevent water ingress.
• Strike wiring: confirm strike voltage/current and polarity; use a suitable 12 V supply path and observe door sensor wiring if fitted.
• Cable runs: keep the 4-core away from noisy mains runs; for longer distances, use coax for the video leg as required.
• Expand cleanly: when adding a second/third monitor, upsize the PSU (e.g. 4 devices → 12 V 4 A) for reliable operation.

FAQs

Does it work with my existing cable? If your old system used a 4-core cable between door and monitor, you’re in luck — that’s exactly what this kit expects. For longer runs over roughly 50 m, use a coaxial video leg with the power/audio cores.

Can I add more monitors later? Yes. You can expand to three indoor monitors. Just upgrade the power supply to match the total device count.

Will it unlock my existing 12 V strike? In most cases yes. Check the strike’s power requirements and wiring diagram. A licensed sparky can confirm compatibility on site.

Can I check it from my phone? No — this is an analogue intercom with no app or cloud features. If you require mobile notifications or remote unlock, look at VIP Vision’s IP intercom range.
