Video Intercom Systems for Gates, Doors and Apartments

We install video intercom systems in Kenya for apartment blocks, gated estates, offices and homes. Visitors press a button at the gate, a resident or guard sees and talks to them, and the door or gate opens only when someone chooses to let them in.

  • Door stations, indoor monitors and phone apps
  • Lock and gate release with a clear audit trail
  • Sized for single homes up to large estates

A gate guard who cannot see a visitor clearly has two bad choices: open the gate and hope, or keep someone waiting while he phones a tenant. A good door phone removes that guesswork. It shows a clear face, lets the resident speak to the visitor and opens the lock with one button. That simple routine is why video intercom systems in Kenya have become standard in new apartment blocks and offices.

This page explains the main types, how we size a system for a building, how intercoms connect to locks and barriers, and what installation involves.

How video intercom systems work

Every system has the same basic parts, whatever the brand. So once you know them, quotes become much easier to compare.

Part What it does
Door station (entry panel) Camera, microphone, speaker and call buttons at the gate or door
Indoor monitor Screen inside the flat, office or guardhouse to see and talk to the visitor
Lock release Relay that opens a magnetic lock, electric strike or gate motor
Phone app (optional) Lets a resident answer calls on a smartphone away from home
Power supply and backup Keeps the system running, ideally with a battery or UPS

When a visitor presses a button, the door station calls the chosen monitor. The resident sees the visitor, talks, and presses an unlock button if they want to let them in. Many systems also take a snapshot of every caller, which is useful when something goes missing.

Intercoms

Analogue, IP and app-based intercoms

There are three broad families of video intercom systems in Kenya, and the right one depends on the size of the building and the cabling already in place.

  • Two-wire analogue systems run on a single pair of wires. They suit houses and small blocks where old intercom cable can be reused.
  • IP intercoms run over standard network cable with PoE power. As a result, they scale to hundreds of flats, support phone apps and link easily with CCTV.
  • App-only or cloud intercoms use a door station that calls residents' phones directly. They suit offices and small sites without indoor screens.

For new apartment buildings, we usually recommend IP. Although the parts cost a little more, the system grows with the building and the cabling serves other uses too.

Video intercom systems for apartment blocks and gated estates

Multi-unit buildings need more planning than a single home. Here is how we approach them.

First, we decide where calls should go. In some estates, every visitor calls the guardhouse, and the guard calls the resident. In others, visitors call flats directly through a keypad or name list, while the guard only watches. Many estates combine both, so residents can let in known visitors and the guard handles deliveries.

Next, we plan the entry points. A typical gated estate has a vehicle gate, a pedestrian gate and a lobby door for each block. Each point gets its own door station, and residents see which entrance is calling.

Building Typical setup
Single home One door station at the gate, one or two indoor monitors
Small block (up to 12 flats) Gate station with name buttons, monitor in each flat
Large block (12 to 100 flats) IP keypad station, monitors or app per flat, guard master station
Gated estate Stations at each gate and block, guardhouse console, CCTV link
Office Reception station, app calls to staff, link to access control

Access control

Linking the intercom to door locks and boom barriers

An intercom only becomes a security system once it controls the entrance. Therefore, we wire each door station to the lock or gate motor, with a short release time so the door closes again quickly.

On pedestrian doors, we normally use a magnetic lock or electric strike with an exit button inside. For vehicle gates, the intercom can trigger a sliding gate motor or a boom barrier. In larger estates, residents use cards or tags for daily entry, and the intercom handles visitors only. Our access control team plans both parts together, so a lost tag never means re-wiring the gate.

Letting visitors in from your phone

With an IP or cloud intercom, a resident can answer the gate from anywhere with mobile data. The app shows the caller's video, and the unlock button works just like the indoor monitor. We set this up with separate accounts per resident, so access can be removed when a tenant moves out.

How it works

Installing video intercom systems: cabling and units

Clean installation decides how long video intercom systems last, because most faults start at a poor joint or a sunny door station. Here is our usual sequence.

  1. Survey and plan. We check every entrance, measure cable routes and confirm where monitors will sit inside each unit.
  2. Cabling. Our technicians run network or two-wire cable in conduit, keeping outdoor runs away from mains cables to avoid interference.
  3. Door stations. We mount stations at a comfortable height, out of direct sunlight where possible, with a rain hood outdoors.
  4. Indoor units. Next, we fix monitors near the main door of each flat, at eye level, with a neat power supply.
  5. Locks and gates. Then we connect release relays, exit buttons and gate motors, and set release times.
  6. Programming and testing. Finally, we set names or flat numbers, test every call path and train the guards and residents.

For a single home, this takes a day. For a 40-flat block, plan on one to two weeks, mostly for cabling inside occupied flats.

Sizing guidance: units, entrances and guards

With these five numbers, we can give a fairly accurate budget even before a full survey.

Connecting intercoms with CCTV

When the intercom and cameras share one network, guards gain a lot, since video intercom systems and CCTV then show the same picture. A call from the gate can pop up the gate camera on the guard's screen, and recordings show every visitor with a time stamp. Our CCTV installation service plans camera views around entry points for exactly this purpose. We also offer guidance for apartments and estates that need cameras, intercoms and barriers together.

Power and backup

Gates and intercoms must keep working during outages, especially at night, so we design video intercom systems with backup from the start. We add a battery backup or a small UPS for the door stations, the network switch and the locks. In addition, we plan what happens when that backup runs out: pedestrian escape doors should open, while a vehicle gate usually stays shut and switches to manual operation. You can read more about backup design on our UPS power backup page.

Choosing equipment

We install and support video intercom systems in Kenya from established manufacturers, choosing models with outdoor-rated door stations, good night images and reliable local spares. Communications equipment sold in Kenya should carry type approval from the Communications Authority of Kenya, and we only supply approved models. For buildings with an older system, we check whether the existing cable can be reused before suggesting new wiring.

Intercoms

Common intercom problems we fix

If you already have a system that frustrates residents, the cause is often simple. In fact, most older video intercom systems we visit share one of these faults:

  • Faded or foggy cameras on door stations that face the sun all day.
  • Broken release relays, so the guard opens the gate by hand.
  • Poor cable joints that corrode after rains and cause crackling audio.
  • No backup power, so calls stop at the worst moment.
  • Missing app accounts after tenants change.

We can repair, upgrade or replace these systems, and we offer maintenance visits under our IT annual maintenance contracts.

Frequently asked questions

What is the difference between IP and analogue intercoms?

Analogue two-wire systems use a simple pair of wires and suit houses and small blocks, especially when old cable can be reused. IP intercoms use network cable, support phone apps, scale to hundreds of units and link easily with CCTV and access control. For new apartment buildings and offices, IP is usually the better long-term choice.

Can one intercom serve a whole apartment block?

Yes. A keypad or name-list door station at the gate can call every flat, and each flat answers on its own monitor or phone app. A guard master station can also take calls and transfer them. We size the system around the number of units, entrances and guard positions on your site.

Can visitors be let in from a phone?

Yes, with an IP or cloud-connected video intercom. The resident's app shows the caller's video and has an unlock button that works like the indoor monitor. We create a separate account for each resident, so you can remove access instantly when someone moves out.

What happens to the intercom during a power cut?

Without backup, it stops working. That is why we fit a battery or small UPS for the door stations, switch and locks. We also agree how each door behaves once the backup runs out, so pedestrian escape doors open and vehicle gates switch safely to manual operation.
