There are many types of intruder alarm systems available on the market. The type of system you decide upon will be based on a number of factors including the type of premises, usage, risk of break in, your expectations of the system, and your budget. Here’s a simple guide of the systems that R Security offer to help you to choose which one is best for you.

Bells-Only alarms

This type of system is your simple standard intruder alarm. If the sensor detects an intruder, an alarm will sound. This can be beneficial to those who have a low budget and only require a very basic system. If activated, the alarm will be sounded but no one will be contacted – it is your responsibility and that of those around you to respond to the intrusion.


  1. Cheap to install and maintain
  2. No cost of a monitoring station
  3. Good if there’s a neighbourhood watch system


  1. Not good for rural areas
  2. Sirens can often be ignored
  3. Sirens can be muted by professional intruders

These types of systems work well in suburban areas, particularly if there is a Neighbourhood Watch scheme where you can be sure that your neighbours will respond to the intrusion and the police will be called.

However, a bells-only system is not recommended for rural or inner city areas as there is less chance of the alarm being responded to. A bells-only system only works if a person hears the alarm and does something about it (e.g. calling the police or intervening at the scene). If you are in a rural location, there may be no response to your alarm so the intruder only has you to face (if they stick around). In more densely populated areas, alarms and sirens are a regular occurrence. Rather than being treated as an emergency situation, it is often ignored by passers-by as being a nuisance.

Dialler burglar alarms

This is the next step up from a bells-only system. As well as sounding an alarm, a dialler burglar alarm will automatically call a number (either yours or that of a friend/family member that you choose) if the sensor detects an intruder.

Most dialler systems allow for many numbers to be added (a minimum of 3 is recommended) to ensure that a contact can be reached in an emergency.

There are two main types of this system: speech diallers and GSM diallers.

A speech dialler uses your landline connection to call the contacts on your alarm system. This means that a wired connection to the alarm system is required.

A GSM dialler will use mobile network signals, meaning that it can be wireless. However, you’ll need a SIM card and it will need to have credit, like a regular mobile phone would, in order to be able to contact your emergency numbers. You must also have a good reception so it may not be useful for rural areas to have this type of system.


  1. No monitoring station costs
  2. Relatively cheap to buy and install
  3. People will still be alerted if you have a break in so you don’t have to rely on neighbours hearing a siren


  1. If a phone connection drops, it becomes a bells-only system
  2. You need to find reliable people that live close by
  3. Speech diallers mean extra wiring

smart home security systems

Smart security systems are the latest in intruder alarm technology. This type of system is connected to a smartphone or tablet which will alert you or a friend/family member should an activation occur.

Smart systems, although expensive, can be the basis of a secure premises. Not only do they activate alarms and alert you to an intrusion, they can work with CCTV systems (which are available to view at any time from anywhere via a smartphone, tablet, or computer) and you can even connect smoke and CO2 detectors on to the system which will notify you of any potential fire or harmful gas.


  1. Your system can be accessed and you will be alerted at any time from anywhere in the world (internet access required)
  2. No monitoring station costs
  3. Wireless


  1. Requires an internet connection
  2. More expensive than Bell Only or Dialler systems
  3. As with all wireless technology, it is at risk of being hacked

If the internet in your area is limited or temperamental, then you may be subject to loss of connection to your system.

monitoring contracts

A monitored system connects to a monitoring station which is manned 24/7 by professional staff. Should an alarm sound, the monitoring station will be alerted immediately. They then  take any necessary action (e.g. alerting the authorities or calling a keyholder).


  1. Action will be taken where necessary, meaning that you don’t have to worry about calling the authorities
  2. Could reduce your insurance premiums if installed and maintained by an NSI Gold accredited company
  3. Don’t have to rely on keyholders to attend if it’s a genuine alarm and be confronted by intruders


  1. These systems cannot be installed by you – they must be installed by a qualified engineer who can connect the system to a monitoring station
  2. Even if the alarm never triggers, a monthly or annual fee must be paid to the monitoring station for their service
  3. If false alarms become a regular occurrence, the police will no longer attend you site
