Intercom Systems
Video door phones, apartment and gate intercoms that let you see and speak to visitors before you open, installed and set up by one team.
Someone is at the gate and you have no idea who it is. You walk out in the rain to check, shout across the compound, or open up for a stranger because there is no other way to know. In apartments it is worse: tenants miss deliveries, caretakers spend the day running to the gate, and the old intercom buzzes in a flat nobody lives in anymore.
Nerpax Systems installs intercom systems that let you see and speak to visitors before anyone opens the door or gate. We survey your property, plan cable routes and handset positions, supply genuine equipment, install it neatly and commission every station so calls connect clearly. Where you have an automated gate or electric lock, we link the intercom so you can open it from inside the house or office.
At handover we show everyone how to answer calls, release the gate and use features such as call recording or mobile app answering where the system supports it. We also repair and replace failing intercoms in older buildings.
Whether it is a single video door phone for a home, a multi-unit system for a block of flats or a gate station for an office, one team handles it from survey to handover.

Why choose us
Planned around your property
We survey the site first, then choose positions, cable routes and equipment that suit your gate, building layout and number of units.
Works with your gate
Because we also install gate automation, we can link your intercom to the gate motor or electric lock so it opens from the handset.
Genuine, reliable equipment
We supply genuine intercom kits with weather-resistant outdoor stations, not low-grade units that fail after the first rainy season.
Neat, tidy cabling
Cables are routed in conduit or trunking and terminated properly, so the installation looks clean and is easy to service later.
Upgrades for older buildings
We replace or repair failing intercoms in apartment blocks and offices, often reusing existing cable routes where they are still sound.
Types of intercom systems
The right system depends on how many entry points and units you have, how far the gate is from the house, and whether you want to see visitors or only hear them.
Video door phones
An outdoor camera station at the gate or door, with an indoor monitor that shows who is calling. This is the most popular choice for homes. Many models store snapshots of callers and support extra indoor monitors in different rooms.
Audio intercoms
Voice-only systems that are simple, durable and cost-effective. They suit offices, internal communication between a gatehouse and reception, and sites where video is not needed.
Apartment and multi-unit intercoms
One entrance panel with a button or keypad for each unit, connected to handsets or monitors in every flat. Tenants answer their own visitors and release the door, which takes pressure off the caretaker and improves security for everyone.
Gate intercoms and app-based systems
A weatherproof station at the gate, wired or wireless to the house. Wi-Fi models can forward calls to your phone so you can answer visitors and open the gate even when you are away.
How to choose an intercom system
- Distance: long runs from gate to house may need a specific cabling system or a wireless link
- Number of units: apartments need a system built to scale
- Gate control: confirm whether you want to open a motorised gate or electric lock from the handset
- Remote answering: decide if you need app access on your phone
- Weather: the outdoor station must handle sun, rain and dust
Think about who will use the system too. Elderly family members may prefer a simple handset with large buttons, while a busy office may want calls routed to reception first. In apartments, plan for the number of units the building may have in future, not only today. We talk through these points during the survey so the system fits how your property actually runs.
What affects intercom installation cost
Your quote depends on the number of stations and monitors, the type of system, cable length and route, and any gate or lock integration. As an indicative 2026 guide, a single video door phone for a home often falls between KES 18,000 and 60,000 installed. Apartment systems are usually priced per unit plus the entrance panel, commonly from KES 10,000 to 25,000 per unit. These figures depend on site; confirm with a free site survey.
Who it is for
- Homeowners who want to see visitors before walking to the gate
- Landlords and apartment owners giving every tenant control of their own entry
- Offices and businesses managing reception, deliveries and staff entry
- Schools, churches and clinics controlling who enters the compound
Intercom integration with gate automation
An intercom is most useful when it can open the gate. We connect intercoms to sliding and swing gate motors, magnetic locks and electric strikes, so you can confirm a visitor and let them in with one button. See our gate automation service for motors and access control.
Maintenance and aftercare
Keep the outdoor camera lens clean, make sure the station is not blocked by plants, and report crackling audio or a dark screen early. Most faults come from damaged cables, water entry or failed power supplies, and they are usually quick to fix when caught early. We offer repairs and servicing for both new and existing systems.
For a complete security setup, add CCTV systems alongside your intercom. Contractors can order intercom kits and accessories from our shop.
