Alarm system installation in Johannesburg

New alarm systems, upgrades and repairs for homes, complexes and businesses across Johannesburg's northern suburbs, planned around how your property would actually be broken into.

Planned around entry points

Every door, window and wall is walked before a single detector is fitted.

Linked to armed response

We install the communicator and test the signals reach your control room.

Any brand repaired

We fault-find and repair alarms another installer fitted, not only ours.

24-month guarantee

Workmanship on every alarm we fit or repair is guaranteed for 24 months.

An alarm built around your property, not a box of parts

Every house, complex and business has its own weak points. Before we quote, we walk the property and look at how someone would get in: over which wall, through which door or window, and how long it would take before anyone noticed. Only then do we decide what goes where.

That planning is what separates a system that works from one that only looks the part. We would rather walk away from a job than fit an alarm that does not protect the property properly.

What we install

  • Control panel and keypads, with zones laid out so you can arm the parts of the house you are not using at night.
  • Indoor detectors (passive infrared), including pet-tolerant models.
  • Outdoor beams along walls, driveways and gardens, so you are warned while an intruder is still outside.
  • Door and window contacts on the openings that matter most.
  • Panic buttons, fixed and wireless.
  • Sirens and strobes, inside and out.
  • Communicators that send alarm signals to your armed response company.
  • Motion-detecting lights, which make an approach to the house visible and often stop it altogether.

Repairs and upgrades

False alarms, a zone that keeps triggering, a keypad that has stopped responding or a siren that does not sound are the calls we get most. We find the fault rather than bypassing the zone, and we tell you when an old panel is no longer worth repairing.

An upgrade does not always mean starting again. Adding outdoor beams or wireless detectors to a sound existing panel is often the best value for money.

Complexes, estates and businesses

Larger sites need a layout that guards can respond to quickly, and equipment that meets insurance and body corporate requirements. We design complex and business alarm systems, and we take on systems other installers have left half-finished.

An owner-run business

One Point is owned and run by Tyson Botha, who still plans and quotes the work himself, with a team that fits and services it. You deal with the people who plan and fit your system.

If your alarm false-triggers, has a zone you keep bypassing, or was fitted before outdoor beams were common, it is worth a look. Tell us what you have and we will say whether it needs a repair, an upgrade or a new panel, then quote in writing.

What our alarm customers say

  • We had an older alarm that kept giving us problems. The One Point team came out, worked through the existing setup and replaced what actually needed replacing instead of trying to sell us a completely new system. Everything has been working properly since. Highly recommend.

  • Our alarm would randomly trigger in the middle of the night and we could never work out why. Tyson found a faulty sensor, replaced it and checked the rest of the system while he was there. No problems since.

  • We recently moved into a house with an alarm system that nobody knew how to use. Tyson from One Point Maintenance checked the whole installation, reprogrammed it and showed us exactly how everything worked. Excellent service.

Questions about alarm systems

Can you work on an alarm system another company installed?

Yes. Most of our repair work is on systems we did not install. We test the panel, every zone and the siren, tell you what is worth keeping, and quote for anything that needs replacing.

Will the alarm still work during load shedding?

An alarm runs on its backup battery when the power is off. Batteries wear out, and a tired one can go flat during a long outage. We check the battery on every service call and fit a larger one where outages are long.

Do you install pet-friendly alarms?

Yes. Pet-tolerant passive infrared detectors ignore animals below a set weight, and outdoor beams can be mounted so they do not catch dogs. We set them up so the system can stay armed while your pets are home.

Can the alarm link to my armed response company?

Yes. The panel sends its signals to your armed response provider over radio or the cellular network. We install the communicator and test that the signals arrive at the control room.

Do you offer maintenance contracts for complex and business alarm systems?

Yes, usually alongside the perimeter: scheduled visits where we test zones, detectors, sirens and the signal to your armed response company, minor repairs on the spot, and a job card after each visit. Contracts run for twelve months at a fixed monthly fee quoted for your property.

How quickly do you respond to an alarm fault under a contract?

Emergency call-outs are attended within 48 hours, during or after office hours, and two office-hours emergency call-outs a month are included in the fee. Work beyond that is charged at the call-out and hourly rates in the contract.

Another company installed our alarm. Will you maintain it?

Yes. We start with an inspection and a written report on what works and what needs attention. Guarantees on someone else's work do not transfer to us, but anything we repair or replace carries our 24-month workmanship guarantee.

Who pays for a replacement alarm panel or detector?

Replacement equipment is not part of the monthly fee. We quote it in writing, the trustees or owner approve it, and new equipment carries the manufacturer's warranty as well as our workmanship guarantee.

For complexes, estates and businesses: what our maintenance contracts cover, how call-outs work, and what trustees get in writing.
