Can I answer my intercom from my phone?

Yes. Both GSM and modern IP/cloud intercom systems allow you to answer visitor calls from a mobile phone or app, granting or denying access remotely from anywhere, not just from a fixed on-site panel.

Can an intercom system integrate with CCTV and access control?

Yes. IP intercoms in particular integrate directly with CCTV systems, access control and offsite monitoring, so every intercom call can be visually verified against live camera footage before access is granted.

How many users can an intercom system support?

It depends on the system. IP network intercoms can support up to 500 devices per master station, while GSM intercoms can support up to 1,000 users per master station and up to 10 phone numbers per user.

Is an IP intercom more expensive to install than an analogue system?

Not necessarily. Because IP intercoms deploy onto your existing network infrastructure, deployment costs are often reduced compared to running new dedicated cabling for an analogue system, especially across larger or multi-building sites.

What type of intercom is best for a gated estate?

Most gated estates benefit from an IP video intercom or GSM intercom, since both allow residents to visually verify visitors remotely from a mobile phone, and can be integrated with boom gates, access control and CCTV for a complete entrance solution.

Can intercom systems be used at boom gates and vehicle entrances?

Yes. Intercom systems are commonly paired with boom gates and vehicle barriers to give drivers a way to request access, which security or reception staff can verify visually before opening the barrier.

How much does an intercom system cost in South Africa?

Cost depends on the number of entrances, the intercom type (analogue, IP or GSM) and any integration with CCTV or access control. A free on-site assessment gives an accurate, tailored quote for your intercom installation.

The Risk of Unmanaged Visitor Access

!Gates and doors opened without verifying who's actually there put staff and residents at risk
!Outdated audio-only intercoms give no visual confirmation of visitors or deliveries
!Reception or security staff tied to a single panel can't manage entry from off-site or after hours
!Cable-only systems are costly and disruptive to install across large or existing sites
!No record of who was granted entry, or when, makes incident investigation difficult

What a Professional Intercom System Delivers

✓Live audio and video verification of every visitor before granting access
✓Remote answering from a mobile phone or app, on-site or anywhere in the world
✓Deployment onto your existing network infrastructure, reducing installation cost
✓Scalable from a single gate station to hundreds of devices across a site
✓Full integration with CCTV, access control and offsite monitoring for verified entry

What Is an Intercom System?

An intercom system is a communication and access-verification device installed at a gate, door or boom, allowing staff or residents to see and speak to a visitor before granting entry. Modern intercom systems range from simple audio-only analogue units to advanced IP video and GSM-based systems that integrate directly with access control and building management systems.

Choosing the right intercom system depends on the size of your site, the number of entry points, your existing cabling infrastructure, and how you want it managed — from a single on-site panel to a cloud-based platform answerable from a mobile phone anywhere in the world.

Types of Intercom Systems We Install

We supply and install the full range of intercom technologies, matched to your site, budget and infrastructure.

Analogue audio and video intercom system

Analogue Intercom

Basic point-to-point wired systems, available in audio and video. A cost-effective option for single-entrance sites, though not upgradeable to larger, networked systems.

IP Network Audio & Video Intercom

Deployed onto your existing network infrastructure to reduce deployment cost, supporting up to 500 devices per master station and integrating directly with CCTV and building management systems.

GSM Intercom

Turns your mobile phone into an intercom handset, reporting directly from the gate station. Ideal where cable routes are inaccessible, supporting up to 10 numbers per user and 1,000 users per master station, controllable from anywhere.

Cloud & App-Based Intercom

The 2026 standard for multi-entrance sites — cloud-managed video intercoms with mobile app access, remote administration, visitor logs and delivery access codes.

Why IP & GSM Intercoms Are the Modern Standard

Video intercom systems have become the preferred option for South African businesses and residential estates, driven by rising security needs and the shift toward cloud-managed access. A modern IP or GSM intercom lets you answer the gate from a mobile phone or app rather than a fixed panel, gives you an audit trail of every visitor, and increasingly includes AI-enhanced features such as facial recognition in low light, visitor analytics and anomaly detection. Because IP intercoms run on your existing network, they're also faster and less disruptive to deploy across large or multi-building sites than legacy cabled systems.

Intercom Integration with CCTV & Access Control

An intercom is most effective as part of a connected security system. Integrated with CCTV cameras, access control and an offsite monitoring control room, every intercom call can be visually verified against live camera footage, and access can be granted remotely by an operator rather than left to an unverified buzzer press. This is especially valuable for gated estates, business parks and sites using electric fencing alongside their perimeter access points.

Where Intercom Systems Are Used

Residential Estates & Complexes

Gate and pedestrian entrance intercoms for estates and communities, giving residents visual visitor verification from their phones.

Commercial Offices & Business Parks

Reception and after-hours entry management for commercial office buildings and multi-tenant parks.

Industrial & Warehouse Sites

Boom gate and loading bay intercoms integrated with access control for controlled vehicle and driver entry.

Retail & Shopping Centres

After-hours delivery and staff entrance intercoms for retail and shopping centre environments.

Boom Gates & Vehicle Entrances

Paired with vehicle barriers for controlled, verified access at estate and business vehicle entrances.

Schools & Healthcare Facilities

Visitor screening at main entrances for schools, clinics and hospitals where controlled access is essential.
