Passive Infrared (PIR) Detector 

Typically one of the most common types of intruder alarms, passive infrared detectors are mounted on walls around a property and are triggered by a change in radiant heat. A single passive infrared detector is capable of monitoring an area between 10 and 15 metres in front of it, meaning you only need to install a few of these around a single building to achieve maximum protection. 

How do passive infrared detectors work?

This type of intruder alarm has two beams that gather information about the space in front of it and splitting it into different 'planes' (up to 20 different zones). If the alarm will sense a change in radiant heat between its planes or zones, for example, if a person enters the room, the alarm will trigger. As you can imagine, an empty shop shouldn't have people walking around it at night, so these alarms are effective at detecting intruders. 

Where should I install a passive infrared detector?

As you can imagine, the passive infrared detectors we mentioned above aren't suitable for all kinds of places. If you installed a passive infrared detector in a family home, for example, you'd probably find it's triggered by the dog multiple times a day! As such, passive infrared detectors are best suited to locations that are vacant for long periods during the day/night. Commercial properties like shops and offices tend to find passive infrared detectors more effective than residential properties.

Quad Element PIR Detectors

If you're worried about false alarms, there is an advanced PIR detector that might be more reliable. On the whole, quad element PIR detectors are similar to the standard passive infrared detectors, however, there are two detectors working side by side. Both need to be triggered to set off the alarm.

How do quad element passive infrared detectors work?

Unlike a standard PIR detector, the quad element PIR detector has four beam planes working at the same time. So, an anomaly in one of the sensors shouldn't lead to a false alarm as often as it might do with a standard PIR detector. This type of intruder alarm has become a lot more popular over the last few years.

Since these alarm systems are more reliable and less prone to false alarms, they can be installed pretty much anywhere!

Monitored Intruder Alarms

Most intruder alarms are great for alerting people in the local area, but that doesn't always mean that someone will respond and stop the incident in its tracks. If you're looking for the best type of intruder alarm to prevent active break-ins, we'd recommend a monitored intruder alarm.

These are regular intruder alarms that are accompanied by a monitoring contract. Here, someone will monitor and respond to suspicious activity in real-time without you having to lift a finger. With this type of intruder alarm & contract, you can rest assured that the relevant emergency services will be on the scene as quickly as possible.

That being said, if you're looking for the highest level of security and you're happy to pay for the additional monitoring service, then this is one of the best intruder alarm options on the market.
