Choosing the Right Security System

Selecting the right security system for your domestic or commercial property can often be difficult as the appropriate solution largely depends on the specific needs of that premises. For example, do you have multiple people entering and exiting the place throughout the day? Is the property vacant or unsupervised for long periods during the day or overnight?

Domestic properties are more likely to be vacant during working hours and require quality locks to protect valuables inside the house and, if necessary, an alarm system to ward off or alert you to intruders. The security measures needed might vary depending on the likelihood of a break in, e.g. is the property located in an area with large amounts of foot traffic? Is the property gated or surrounded by high walls or fencing?

Commercial properties on the other hand are most exposed outside of working hours at night. They also have a greater number and variety of people entering the property at all time who could possibly engage in theft or sabotage. The fact that there is often a large amount of valuables on the property, whether in the form of expensive products like computers or intellectual property, also make commercial premises a bigger target.

Our security experts can assess your property and help you determine an appropriate security solution by evaluating all potential threats and finding the most effective and cost-efficient way of protecting the premises. The solution may involve one or more of the below systems depending on your needs and wishes.


Security alarm systems can be hard wired, wireless or a combination of both depending on the type of property you have and your specific security needs. These systems work by using a number of sensors that send messages to a central security system control panel. The sensors can activate loud alarms or strobe lights and operate using motion sensors, glass break sensors, smoke and heat detectors, remotely operated panic switches and more depending on your needs.

When the system is armed and a signal from a sensor is received, it can be configured to automatically contact any number of pre-programmed phone numbers. This could be you, a trusted friend or one of our trained operators at our Central Monitoring Station who are on standby 24/7 and can take the appropriate action, whether that is contacting the police or the CFA. These systems are highly flexible and easy to operate, allowing you to arm and disarm them using a key fob.


CCTV technology has advanced over the years, now offering hi-resolution colour video, infrared cameras, day and night cameras and pan tilt zoom (PTZ) cameras. Video surveillance is mainly used as a security solution for commercial premises who want to be able to capture evidence of theft and misconduct should it occur.

However, some people choose to use CCTV on their domestic property as it can offer an extra powerful and reliable level of security. The very sight of a security camera is often a strong deterrent to any would be wrongdoer.

Access Control Systems

If you want to limit or restrict access to a building or certain area of a building, access control systems are your ideal solution. Used primarily for major commercial premises, these systems allow you to restrict access to visitors and staff members to places where there may be sensitive or valuable property.

This sophisticated security system essentially creates an impenetrable barrier to unwanted intruders with the added option of tracking who enters restricted areas, when and for how long using an automated computer log. Using the system is easy with a keyless access control panel.

Don’t leave the security of your premises to chance. Call us now on 1300 315 522 or send your enquiry to find out how Twenty First Security can help protect what’s important to you.
