Ajax Security Systems in Harare & Across Zimbabwe: The Smart Alarm Built for Load Shedding

Break-ins don't wait for a convenient time — and neither does load shedding. Whether you're in Harare, Bulawayo, Mutare, Gweru, or a smaller town in between, if you've ever worried that your alarm system might be useless the moment ZESA cuts the power, you're not alone. It's one of the most common questions we get at Interlock Security Solutions, and it's exactly the problem Ajax security systems were engineered to solve.

Ajax is one of the world's most awarded wireless security brands, and it's fast becoming the go-to choice for homeowners and businesses across Zimbabwe who want an alarm system that actually stays online — through power cuts, network outages, and everything in between. Here's what makes it different, and why it might be the right fit for your home or business, wherever in Zimbabwe you're based.

What Is an Ajax Security System?

Ajax is a wireless smart alarm system built around a central control panel — called the Hub — that communicates with a network of sensors, cameras, and accessories placed around your property. Instead of running cables through your walls, each device connects wirelessly to the Hub using Ajax's own encrypted radio protocol, which keeps installation fast and keeps your walls and ceilings untouched.

Everything is managed from a mobile app, so you can arm or disarm the system, check sensor status, and receive instant alerts on your phone — whether you're in the next room or on the other side of the world.

Why Ajax Is a Strong Fit for Harare and the Rest of Zimbabwe

It keeps working through load shedding

This is the feature that matters most to Zimbabwean homeowners. The Ajax Hub has a built-in rechargeable battery that keeps the system running for hours after the mains power goes off, and most Ajax sensors run on long-life batteries rated for years of use rather than relying on the grid at all. Your alarm doesn't switch off just because ZESA does.

It doesn't depend on one connection failing you

The Hub can maintain more than one way of reaching the outside world — Ethernet and a cellular (SIM-based) connection — and automatically switches between them if one drops. That matters in areas where fibre or ADSL can be unreliable: if your home internet goes down, the system can still report to your phone over the mobile network.

It's quick to install without disruptive rewiring

Because every device connects wirelessly to the Hub, installation is significantly faster than a traditional wired alarm, with far less mess. That's especially useful for tenants, recently built homes, or business premises where you don't want cables running through finished walls.

It's built to resist tampering and jamming

Ajax devices authenticate with the Hub on every connection and use encrypted communication, with built-in alerts if a device is tampered with, removed, or if someone attempts to jam the signal — an important layer of protection against more determined intruders.

What's in an Ajax Security Kit?

A typical Ajax setup for a Harare home or small business includes a combination of:

• Hub – the central panel that connects to your phone and, where needed, to an armed response company

• MotionProtect / MotionCam – motion detectors (some with built-in photo verification, so you can see what triggered an alert)

• DoorProtect – door and window contact sensors

• GlassProtect – detects breaking glass

• StreetSiren / HomeSiren – indoor and outdoor sirens to scare off intruders and alert neighbours

• FireProtect – smoke and heat detection, useful given Zimbabwe's frequent power surges and electrical fire risk

• Keypad / SpaceControl remote – for arming and disarming without reaching for your phone

Systems are modular, so a kit can be scaled up from a small flat to a large property, a shop, an office, or a warehouse.

Ajax vs. Traditional Wired Alarm Systems

Older wired alarm systems can still do the job, but they usually depend entirely on mains power and a fixed phone or internet line to report an alarm — both of which are exactly what fail first during a power cut or cable fault. Wired systems also typically require more invasive, time-consuming installation. Ajax's wireless design and dual-connectivity backup are the main reasons it's gained ground quickly among security-conscious buyers in Zimbabwe and the wider region.

Ajax Installation Across Zimbabwe: Not Just Harare

Interlock Security Solutions is based in Harare, but we regularly travel for installations across the country.

For jobs outside Harare, we typically combine a remote site assessment (photos, floor plan, or a video walkthrough) with an on-site visit for installation, so you get an accurate quote before we travel.
