South Africa has one of the highest residential burglary rates in the world. A functioning alarm system connected to a reliable monitoring company is one of the most effective deterrents you can put in place — but only if you choose the right provider. A cheap installation from an inexperienced company can leave gaps in your coverage, generate constant false alarms, or fail entirely during loadshedding when you need it most.
This guide covers what to look for when comparing alarm system companies, the questions to ask before signing a contract, what a proper installation should include, and the hidden costs that catch South African homeowners off guard.
Understand What You're Actually Buying
An alarm system is more than a siren. It includes detection hardware — motion sensors, door and window contacts, vibration detectors — a control panel, a communication module, and a link to an armed response control room. The quality of each component and the reliability of the monitoring connection determine how useful your system actually is.
Some companies sell hardware at a low upfront cost and make their money on monthly monitoring contracts. Others charge more upfront for quality hardware and offer lower monthly fees. Neither model is automatically better — but you need to understand the total cost over a 24-month period before comparing quotes.
Ask each company: what brand of hardware do you install, what is the expected lifespan, and what happens to my system if I cancel the monitoring contract? Some companies use proprietary panels locked to their control room — useless if you switch providers. Others use open-standard systems that any monitoring company can connect to. Clarify this before you sign anything.
At minimum, your system should include perimeter protection (door and window contacts), internal motion sensors, a tamper-resistant control panel, backup battery power sized for loadshedding, and a cellular communicator that doesn't rely solely on your home's Wi-Fi or a landline that may be cut.
Check Monitoring Response Times and Control Room Standards
The monitoring contract is often more important than the hardware. When your alarm triggers, it's the control room that decides how fast a response vehicle reaches you. In South Africa, response time can determine whether a burglary is interrupted or completed.
Ask any prospective company for their average response time in your specific suburb, not a citywide average. Response times vary significantly by area depending on the density of their vehicle fleet. A company claiming a five-minute average in Sandton may take twenty minutes in a suburb where they have fewer patrol vehicles.
Find out whether the company operates its own control room or outsources monitoring to a third party. In-house control rooms generally allow faster escalation — the operator who picks up your alarm can immediately dispatch their own vehicles rather than relaying through another company's dispatch.
Check whether the control room has backup power, redundant communication lines, and is graded by the South African Intruder Detection Services Association (SAIDSA). SAIDSA grades control rooms from Grade A to Grade D based on their resilience and staffing standards. A Grade A or Grade B control room is a meaningful quality marker worth asking about specifically.
Also ask whether the monitoring contract includes panic button and medical response in addition to intruder alarms — many companies include this at no extra cost, and it's worth confirming upfront.
Verify PSIRA Registration and Insurance
The security industry in South Africa is regulated by the Private Security Industry Regulatory Authority (PSIRA). Every security company and individual security officer must be registered. Before signing any contract, ask for the company's PSIRA registration number and verify it on psira.co.za. An unregistered company is operating illegally — don't proceed under any circumstances.
Check whether the technicians installing your system are individually PSIRA-registered. A registered company can still employ unregistered installers — and if something goes wrong, your legal position is weaker. Ask for the installer's registration before they set foot in your property.
Ask whether the company carries public liability insurance and professional indemnity cover. If an installation error damages your property or a faulty alarm causes an incident, you need to know the company is insured. A reputable company will produce their insurance certificate without hesitation — treat reluctance as a warning sign.
Membership in the South African Security Association (SASA) or SAIDSA beyond basic PSIRA compliance indicates a company that subjects itself to additional professional standards and oversight. It's not mandatory, but it's a positive signal when comparing similarly priced providers.
Read Every Line of the Contract
Alarm company contracts in South Africa are typically written in favour of the provider. Before you sign, read every clause — particularly around early cancellation, equipment ownership, and annual price escalations.
Standard monitoring contracts run 24 or 36 months. If you cancel early, some companies charge the full remaining value of the contract as a penalty. Others will physically remove their hardware if you cancel, even if you paid for it upfront. Clarify in writing what happens to the equipment at contract end and what your obligations are if you move house mid-contract.
Many contracts include an annual escalation clause, typically linked to CPI or a fixed percentage — often 10 to 15%. On a five-year relationship this compounds significantly. Ask what the escalation rate is and whether it's capped.
Find out what's included in the monthly monitoring fee and what triggers a call-out charge. Some companies charge per response visit after a certain number of calls per year. False alarms — often caused by a poor installation — can generate unexpected bills. Understand the threshold before you commit.
If the company requires proprietary hardware, try to negotiate ownership of the equipment or the right to have the system reprogrammed if you switch providers in the future. Get any agreement on this in writing, not just verbal reassurance from a salesperson.
Evaluate Installation Quality
The installation is where corners are most often cut. A rushed job leaves blind spots in your coverage, creates chronic false alarm problems, and may fail during extended loadshedding if the backup battery is undersized.
Before installation, ask the technician to conduct a site survey and explain where each sensor will be placed and why. Reject any company that quotes without seeing your property — coverage requirements differ enormously between a small cluster home and a large freehold property with outbuildings and a garden.
Ask what brand and capacity of backup battery will be installed. A standard 7Ah battery typically provides 6–8 hours of backup; a 17Ah battery lasts longer. If you're in an area with heavy loadshedding, battery capacity directly affects whether your system keeps running through the night. Don't accept a vague answer — ask for the amp-hour rating in writing.
Confirm that all wiring will be concealed. Exposed cables along skirting boards or through poorly drilled holes are signs of an unprofessional installation. After the job is complete, test every zone individually before the technician leaves. Ask for a written handover document listing every installed component, every zone name, and your panel access code. This is your system — you're entitled to full documentation.
Read Local Reviews and Ask for References
Response time and service quality vary dramatically by suburb, by technician, and over time as companies grow or cut costs. National brand recognition doesn't guarantee local service quality — a large company may be excellent in one city and unreliable in another.
Search for reviews specific to your area, not the company's national profile. Look for recurring patterns: slow response times, false alarm complaints, difficulty cancelling contracts, and poor after-sales service are the most common issues that surface in South African alarm company reviews. One or two complaints are inevitable for any large provider; a pattern of the same complaint is a red flag.
Ask the company for two or three references in your suburb — homeowners who've had the system for at least a year and can speak to both the installation experience and ongoing monitoring. A company that won't provide local references usually has a reason for that reluctance.
Local Facebook community groups and neighbourhood WhatsApp groups often contain more honest assessments than formal review platforms. Search for the company's name in your area's community groups before committing. Current customers with no reason to sell you anything give you the most accurate picture.
