Unravelling the World of Security Alarm and Monitoring Options Are you considering upgrading your home security but feeling overwhelmed by the options available? Look no further! This comprehensive guide will equip you with valuable insights from our security experts, shedding light on alarm and monitoring systems for residential and commercial security. By making an informed choice, you can ensure the utmost protection for your premises and find peace of mind knowing that your security needs are met. What is an Alarm System? Not to be confused with CCTV (security cameras),however often used in conjunction with cameras the alarm (noise maker) has successfully been used to enhance security measures by detecting intruders for decades. Throughout history, the alarm system has been a reliable means of safeguarding properties. Its origins can be traced back to 390 BC when geese were employed as a loud alert system to warn against intruders. Fast forward to 1853, when Augustus Pope invented the first “burglar alarm.” This ingenious device connected doors and windows through a circuit, triggering a hammer that struck a brass bell when the circuit was disrupted. The fundamental principle behind this system remains unchanged, although technological advancements have significantly improved its capabilities. The 1980s and 1990s witnessed a surge in popularity for alarm systems among homes of distinction in Canberra used to detect and alert the occupants of intruders. In the past decade alone, technological advancements have revolutionised the security industry. If you have one of these older alarm system installed in your home, it’s time to consider an upgrade! Simply put, if your current alarm system is on the 3G network and doesn’t provide adequate protection, you leave yourself vulnerable to potential intruders. Now, let’s delve into the key differences between professionally monitored systems and self-monitored systems, which often rely on smart devices for notification of events. “Which monitoring system is the best fit for you, and how do you make that choice?” Discover the answers to these questions and learn how to improve the security of your home or business. Each security system type self-monitoring and back-to-base monitoring has its own pros and cons. The best choice for you depends on your specific needs, property, budget, lifestyle, and preferences. Monitored Alarm Systems Offering back-to-base monitoring, where a triggered alarm prompts a response from the monitoring company. This is particularly effective for commercial and residential security, especially when occupants are frequently away from the premises including overnight when crime often occurs. If you fall into one of the following categories, a monitored system might be the perfect fit for you: • You own a commercial property • You travel frequently • You work long shifts or are away from home for extended periods • You don’t have the time or inclination to self-monitor •You don’t consider yourself tech savvy Having a security system that can keep an eye on your home or business while you’re away is crucial for protecting it. Here are some of the benefits of professional monitoring of your alarm system: • 24/7 monitoring • Duress alarms (yes, the big red panic button) • You don’t need to be tech-savvy • It’s great for clients who travel often • It’s great for clients with busy lifestyles who don’t have time to self-monitor • If selected, it can detect environmental changes like smoke or water • It provides protection for staff in commercial environments • It protects your property • It gives you peace of mind Some reasons why our clients choose a monitored system: • Immediate response during emergencies, even when you’re away from the property. • 24/7 protection. Users who can’t manage security via smartphone apps or don’t have the time to constantly monitor their devices due to busy lifestyles can rest assured that their property is being professionally monitored 24/7, so they don’t have to. • Insurance discounts . Potential lower premiums due to reduced risk recognised by some insurers. Some deterrents people have previously found when selecting a monitored system. Over the years, clients have been deterred by long-term contracts or companies repeatedly selling their monitored lines to different businesses. This leaves the end-user uncertain about the security company monitoring their alarm and without a point of contact for inquiries or maintenance. “We often come across clients who are extremely frustrated because their system hasn’t been maintained for a long time. They’ve switched off their unit, leaving them completely vulnerable without any security at all because they find it “too difficult.” Advantages of a SSTG monitored alarm system: No lock-in contracts Local Canberra company Grade 1A control room—the highest level and most secure A local response service Contract with a single local company, not an overseas-owned provider that has been sold multiple times to other companies. Canberra local In-house professional installation, maintenance and service of equipment. We’re always here for you when needed! Self-Monitored Alarm Systems Self Monitored Systems involve the homeowner managing and responding to alerts from their security system, typically through a smartphone or device. Advantages of monitoring your own security alarm system - Ideal for tech-savvy individuals interested in monitoring their residence or premises for security reasons. - Self-management of your alarm system can be effective if: - You have the time - You’re looking for an economical option - You value control and flexibility. Homeowners can customise their alerts, receive real-time notifications, and integrate their security system with other smart home devices. The downside of self-monitoring your alarm is the responsibility and stress it places on the homeowner to monitor and respond to alerts. There’s also the need for technical knowledge to set up and maintain the system, and potential gaps in monitoring if the property owner is unavailable or unable to respond promptly. - You’ll always need a smart device with you to receive a signal or notification - You’ll need the time to monitor 24/7. - Any action regarding a break-in or alarm triggering is solely on you. Choosing the right home security monitoring system is a pivotal decision that can significantly enhance your safety and peace of mind. At SSTG, our philosophy revolves around providing comprehensive layered security solutions to ensure that there are no gaps in your overall security plan. An ideal pairing is to combine an alarm system (detection) with CCTV cameras (evidentiary). Additionally, incorporating barrier protection measures such as Crimsafe security screens (barrier) or roller shutters can significantly fortify your premises and provide comprehensive security. If you have an existing alarm system that requires service or upgrades or would like to discuss installing a new system in your premises we invite you to contact SSTG for professional advice.
