Is Your Hertfordshire Property Really Secure? A Guide to Intruder Alarms
If you’ve been wondering whether it’s worth getting an intruder alarm for your Hertfordshire home or business, the latest crime data offers you a clear reason to do so without delay. Last years 2025 crime stats for Hertfordshire report a 2.1% increase in burglaries across the county. This upward trend highlights a growing risk for local properties and a clear case for installing intruder alarms in Hertfordshire.
Which is where we come in. As a long-established local provider (since 2006), 1st Choice Security Systems has a detailed understanding of the security challenges faced by our Hertfordshire customers. We won’t throw lots of technical jargon at you, therefore. Our aim is clear – to offer friendly guidance which will help you select a professionally installed intruder alarm that perfectly matches your needs.
What Real Security Feels Like
Having the right intruder alarm provides you with more than protection for your valuables – it surrounds your property with a protective shield, so you know that intruders are actively deterred from even trying to break in. It’s the reassurance that, should a break-in occur, your system will send out an instant alert leading to a fast response. It’s about knowing your home or business is protected and watched over, even when you’re not there.
In order to tailor that feeling of security to your Hertfordshire property, 1st Choice starts with a free, no-obligation security audit. This allows our engineers to identify vulnerabilities you may not have noticed, guaranteeing that your alarm system is a complete security solution, not just a box on the wall.
What Are The Main Types of Intruder Alarms?

Understanding what your options are helps to put you in control of your intruder alarm options. And alarms are not that complicated! Most of the professional alarm systems we install in Hertfordshire fall into three categories, each of which offers a different level of response.
- The Basic Deterrent – Bells-Only Alarms
This is the system you’re most likely to know about. When triggered, a loud, external siren goes off. Its main job is to scare off an intruder and let your neighbours know that something’s up. It’s a simple deterrent that makes your property less of a target for burglars.
- Pocket-Sized Protection – Smart Alarms
A smart alarm gives you immediate control through an app on your phone. As well as activating a siren, it sends an instant notification to you and your chosen contacts if it’s triggered. This means you’re the first to know about any issues, wherever you are, allowing you to check your CCTV cameras or contact the police yourself.
- The Ultimate Deterrent – Monitored Alarms
This is the best level of security you can get. When a monitored alarm is activated, the signal is sent directly to a professional Alarm Receiving Centre (ARC). A team is on-hand 24/7 to verify the alarm and, if necessary, immediately dispatch the police or a keyholder to your property.
How Do I Choose the Right Alarm for my Home or Business?
Now that you know the main types, we can work out which one is the perfect fit for your property. Just ask yourself the following questions. Your answers will point you directly to the system that’s the right fit for you.
1. Who do you want to respond to an alarm?
If you have neighbours who are likely to take positive action in response to a loud siren, a Bells-Only system is a good choice. If you want to be in control and decide on the response yourself, a Smart Alarm that sends an alert to your phone is ideal. If you would prefer a guaranteed, professional police or keyholder response, you need a Monitored Alarm.
2. How important is your insurance policy?
For many businesses and some home insurance policies, having a professionally monitored system is essential to ensure you are fully covered. If this is an issue for you, a Monitored Alarm that provides a unique reference number (URN) for police response is the only option.
3. What will give you the greatest confidence?
This is the most important question. Is it the simple, powerful deterrence of a siren? The control of having alerts on your phone? Or the reassurance of knowing a professional team is watching over your property 24/7?
These questions provide a great starting point, and our free, on-site security audit can help you confirm your choice with the support of professional guidance.
