Crime is on the up in Melbourne. And it’s indiscriminate, every home is a target. So is your property protected?

We’re not talking about the expense of hiring private security. We’re talking about something much more affordable, reliable and proven to be both an effective deterrent of crime as well as a guaranteed way to catch criminals in the act. We’re talking about home security CCTV systems.

At Defend Security Group, we give you the power to know exactly what’s been happening in your home 24 hours a day. Nothing is left to question. The moment an incident occurs you can check your irrefutable record and take the action to make sure it never happens again. Home security cameras are even more useful as a deterrent. The mere sight of a camera is enough to make people think twice about their actions.


Anytime/Anywhere Home Security

Home security systems come with mobile apps that bring surveillance video right to your iOS® or Android™ tablet or smartphone. To oversee multiple systems in various locations allows video monitoring from all points around the globe on a single screen.

Instant email notifications can be sent when motion or camera tampering is detected and automatically recorded onto the home DVR. Guarding your safety, our home security systems empower you to respond instantly to unexpected events, view real-time activity and review stored recordings.

I highly recommend you use this company for security installation based on my experience with Pryce today.

Are home 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 house 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 home security system increase property value?

Adding Security Cameras Increase Home Value. Most experts believe that installing a home security system will increase a home'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.
