Business security cannot be overlooked. With the rising crime rate in Melbourne as we resurface from lockdown, there has never been a more important time to invest into business security. Stay one step ahead of unwanted crime, theft or vandalism at your premises.

If you run a business you’re the only one who truly appreciates it’s value so it makes sense to look after it and to avoid becoming a victim of crime. Having a visible professional CCTV system is a big step towards looking after your business and not becoming just another crime statistic.

We protect everything. Including your privacy. Melbourne, Victoria

Take Your Business Security to the next level

At Defend Security Group we’ve been installing CCTV systems in commercial properties for years and we understand what works. You can’t have cameras everywhere but there’s an important balance between having them in the right places to deter potential criminals and having them positioned to capture the images you need.

Our technicians can identify the most likely access points for a break in and suggest the best positions to mount cameras to counter this. So whether you’re looking for a small system for a shop or bar or whether you need a system for a large industrial unit we can provide the most effective solution for your business.

Frequently Asked Questions

Are commercial security systems worth it?

There's no question that alarm systems deter crime and can increase the odds of catching a burglar if your home does get broken into. Security systems and monitoring discourage break-ins: 60% of convicted burglars say they will target another home if they discover a security system in the one they are trying to rob.

How many alarm sensors do I need?

You don't need countless motion sensors for your home's security system to be effective. In fact, having too many motion sensors can render your security system useless. Since motion sensors tend to have the capability to monitor a large amount of area, one motion sensor per room is typically effective.

Do cameras deter burglars?

Security cameras will generally deter and reduce burglary. If you install a security camera, your home is 300 % safer from break-ins than a home without a camera. Criminals don't want to be watched or recorded-this is one of the major reasons they are so effective.

Do business alarms work?

Burglar alarms are widely used as a means to try to reduce the risk of domestic burglary. Previous research has suggested that some burglars are deterred by alarms and that they are therefore effective. It finds that alarms have become associated with increased rather than decreased risk of burglary with entry.

Is wired or wireless CCTV better?

Wired cameras are a good solution if you have an inconsistent or unreliable Wi-Fi signal. They are also a great option if you own a large property with a lot of area to cover. Wireless signals don't extend very far – 300 feet at most without a wall or anything else to block the signal.

Does a business security system increase property value?

Adding Security Cameras Increases property asset value. Most experts believe that installing a business security system will increase a business's value and are an item prospective buyers look for. Security cameras are another upgrade that buyers appreciate, as well as sensor-operated security lights.
