5 Warning Signs Your Commercial Security System Needs an Upgrade

Most business owners in Adelaide do not think about their security system until something goes wrong. A break-in, a staff dispute over who was on site, a police request for footage that turns out to be unusable. By then the system has already failed at the one job it had.

The numbers show why this matters. The Australian Bureau of Statistics recorded 8,789 burglary victims in South Australia in 2025. Around three quarters of those were residential, which leaves roughly one in four break-ins happening at business premises, warehouses, shops and other non-residential locations. On top of that, South Australia recorded 42,392 victims of other theft in the same year, and more than half of those offences (53%) took place at a retail location. You can read the full release on the ABS Recorded Crime – Victims page.

Security equipment does not last forever. Cameras lose sharpness, alarm panels stop receiving updates, and the networks older diallers relied on have been switched off. Below are five signs that your commercial security system is past its best, and what a modern replacement looks like.

Your footage is not clear enough to identify anyone

This is the most common complaint we hear from business owners after an incident. The cameras recorded something, but the image is too dark, too grainy or too far away to be useful to SAPOL or an insurer.

Older analogue and early HD systems were installed when 720p was considered high definition. That resolution cannot reliably capture a face at the front counter or a number plate in the car park. Poor low-light performance makes the problem worse, because most break-ins happen after hours.

Signs your cameras are no longer doing their job:

• Faces and number plates are unreadable beyond a few metres
• Night footage is a wash of noise or infrared glare
• There are obvious blind spots at entries, loading docks or the till
• The recorder only stores a few days of footage before overwriting
• You cannot view live or recorded footage from your phone

Current commercial CCTV systems record in 4K, hold weeks of footage, and use analytics to flag people or vehicles in restricted areas rather than every passing cat or headlight. If your cameras were installed more than six or seven years ago, it is worth having them assessed. See our commercial security cameras page for what a modern installation includes.

Your alarm still relies on a phone line or a 3G dialler

An alarm is only useful if the signal gets through. For years, commercial alarm panels sent their signals over a landline or a 3G mobile module. Both of those paths are now unreliable or gone.

Telstra and Optus switched off their 3G networks from 28 October 2024, as confirmed by the Australian Communications and Media Authority. Any alarm communicator still relying on 3G cannot report to a monitoring centre. Copper landlines have been progressively retired since the NBN rollout, and a panel connected through a VoIP adaptor can drop out with every internet or power interruption.

If you are not sure how your alarm communicates, ask yourself:

• Was the panel installed before 2020 and never updated?
• Has your monitoring centre ever mentioned missed test signals or polling failures?
• Does the alarm still plug into a phone socket on the wall?
• Do you rely on a neighbouring tenant or a staff member to call you if the siren sounds?

Modern panels use 4G and IP dual-path communication, so the signal reaches the monitoring centre even if one path fails. Our alarm monitoring in Adelaide runs through a 24/7 A1-grade centre, and our alarm system upgrade page explains how existing sensors can often be kept while the panel and communicator are replaced.

You cannot control who has access, or when

Keys get copied. Alarm codes get shared with the new casual and never changed when they leave. If your only way of controlling entry is a set of physical keys and a single four-digit code that everyone knows, you have no real record of who was in the building and when.

Common signs of an access problem:

• Former staff or contractors may still hold keys
• Everyone uses the same alarm code
• You have had to change locks after a staff departure
• Deliveries, cleaners or tradespeople are let in with no record
• You manage more than one site and cannot see any of them remotely

Electronic access control solves this with cards, fobs or smartphone credentials that can be issued and cancelled in minutes. Each entry is logged, doors can be scheduled to lock automatically, and a lost fob is disabled without touching a single lock. For businesses with multiple locations, the whole thing is managed from one dashboard.

Nobody is watching when the alarm goes off

A siren on the wall tells the neighbourhood there is a problem. It does not tell anyone who can actually respond. Self-monitored systems that send a push notification to the owner’s phone are better than nothing, but they fail when the phone is on silent, the owner is overseas or the alert is one of a dozen false alarms that week.

SAPOL’s rolling-year figures show shop theft in South Australia at 17,956 reported offences, up from 16,802 in the previous period, according to the August crime statistics from South Australia Police. Retail and hospitality operators in particular need a response plan that does not depend on one person’s phone.

Warning signs here include:

• The alarm has been triggered and nobody knew until the next morning
• False alarms are frequent enough that staff ignore them
• The monitoring contract lapsed and was never renewed
• There is no video verification, so patrols are dispatched blind

Professional alarm monitoring means a trained operator sees the event, checks the cameras through our video monitoring service, contacts your nominated keyholders and dispatches a patrol if required. That process runs whether you are asleep, on a plane or in a meeting.

Your system has not been serviced in years  

Security hardware is like any other plant and equipment. Batteries in sensors and panels wear out, cameras shift out of alignment, and firmware falls behind. A system that has not been inspected in two or three years will usually have several faults that only show up when it is needed.

There is a second problem with older equipment that many business owners overlook. Internet-connected recorders, cameras and panels that no longer receive manufacturer updates become an entry point into your business network. The Australian Signals Directorate’s Annual Cyber Threat Report 2024-25 recorded over 84,700 cybercrime reports, an average of one every six minutes, and put the average self-reported cost of cybercrime for a small business at $56,600, up 14% on the previous year. The same report observed more than 120 incidents involving attacks on internet-facing edge devices, of which 96% were successful, and its advice to business is direct: replace legacy technology or put appropriate mitigations in place. The full report is on the Australian Cyber Security Centre website.

Signs your system is overdue for attention:

• The recorder or panel is no longer supported by the manufacturer
• Default passwords have never been changed
• Cameras are accessible from the internet without a VPN or secure cloud service
• Sensors show low battery or tamper faults that nobody has cleared
• Your insurer has asked for evidence of a maintained, monitored system

Our maintenance program covers a full inspection of the system on site and from the monitoring centre, tested to Australian Standards, with a written report of faults and vulnerabilities. If the equipment is simply too old to secure, we will tell you, and we will explain what can be reused.

What a commercial security upgrade actually involves

An upgrade does not always mean ripping everything out. In many Adelaide businesses, the cabling, sensors and camera mounting points are fine, and the cost sits in the recorder, panel, communicator and cameras themselves. A licensed technician should:

• Audit the existing system and identify what can stay
• Recommend equipment that suits the site, not a generic package
• Replace communicators with 4G and IP dual-path units
• Set up secure remote viewing and user management
• Connect the system to a graded monitoring centre
• Provide a service schedule so the system stays reliable

For businesses running cameras, alarms and access control as separate systems, an integrated security solution brings them onto one platform, so an alarm event automatically pulls up the relevant camera and door log.
