The security of your home or business should always result from a considered and balanced review of your current set up. Having an effective intruder alarm system in place is essential and so, below we’ve listed some frequently asked questions that can help you make an informed decision, when choosing the right intruder alarm setup.
Q: What three types of intruder alarms can be used in a security system?
A: There are three types of intruder alarms that can be used in a security system. These are bells-only alarms, auto-dialler alarms, and monitored alarms.
Bells-only alarms are the simplest and most affordable type of alarm system. They produce a loud noise when triggered, but they do not alert anyone outside the property.
Auto-dialler alarms call a list of pre-programmed numbers, such as the police or a friend or family member when triggered.
Monitored alarms are the most advanced type of intruder alarm system. Connected to a monitoring center an operator is alerted when the alarm is triggered. The monitoring center can then notify the police or other emergency services if necessary.
Q: What is a Grade 4 intruder alarm?
A: A Grade 4 intruder alarm is a type of alarm system that meets the highest level of security standards. These systems are typically used in high-risk commercial or public sector buildings that require a high level of protection against theft or damage.
Q: Do alarm systems deter thieves?
A: Yes, alarm systems are an effective deterrent against intruders. Studies have shown that properties with alarm systems are less likely to be targeted by burglars. The fact that dummy cameras can look so realistic, means that when a burglary is attempted or underway, once spotted, these cameras can effectively halt thieves in their tracks and make them think twice if they believe they are on camera.
Q: Are dummy burglar alarms effective?
A: While dummy burglar alarms can provide a visual deterrent, they are not as effective as real intruder alarm systems. They do not provide any actual security or protection and can give a false sense of security. However, as mentioned above, they can still provide the illusion of protection of the property as far as the thieves are concerned. Ultimately, if it deters them, then it has done its job. As a long-term solution though, it’s preferable to have a suitable security recording system fitted.
Q: What is the British standard for intruder alarms?
A: The British standards which relate to the security industry for intruder alarms is BS EN 50131. This standard specifies the performance requirements and test methods for intruder alarm systems.
Q: What 2 types of detectors should you have in your house?
A: The two types of detectors that should be included in an intruder alarm system for a house are motion sensors and door/window sensors. Motion sensors detect movement in a room, while door/window sensors detect the opening and closing of doors or windows. These are the most popular systems that most domestic properties have installed, mainly for protection on back doors or garden patio doors, for example. Motion sensor technology is also ideal for monitoring systems with remote applications, such as using an app on a mobile phone when you are away. Monitoring companies can also provide 24/7 protection for when you are away for periods of time, offering you peace of mind when you need it.
Q: What is the most effective type of alarm system?
A: Monitored alarm systems tend to provide the highest level of security, as they are connected to a monitoring center that can respond immediately when the alarm is triggered. Monitored alarm systems provide a high level of protection for your home and business but they won’t always be suitable for everyone. Perhaps you just need alerts to your phone when there is movement at your home, or maybe you just want an alarm trigger to deter any potential break-ins, which are loud enough to cause a disturbance and bring attention to your property.
Commercial Security For Larger Properties

With new technology comes new possibilities and less limitations. Commercial business sites which cover large areas (such as warehouse depots or distribution sites) can be more exposed and require specific security measures to keep the business and its staff safe.
Multiple buildings can mean you need round the clock protection, whether it’s through night time CCTV systems or entry-level intruder alarms and access control systems on your entry and exit points. You can pair intruder systems with other security measures such as CCTV and your property would be monitored remotely with 24/7 support.
This ultimately reduces the need for security staff and manned station posts, cutting spend on man-hours and offering an easy and efficient solution.
Many insurance companies now require that you have installations of grades 1 to 4 for intruder alarm systems. This grading system outlines what the suspected risk would be that is covered by each system. Insurance policies can often dictate which set-up you would need for coverage and that you would have to have an NSI Gold/Silver security installer provide the system installation. Or a fitter that has an SSAIB certificate.
