What type of Outdoor Alarm Sensor should I use for my Outdoor Alarm & Alert systems, four common models are listed below:
PIR (passive infrared):
Positives:
- These are the quickest and easiest Sensors to fit.
- Most have a detection range from 10 – 15 metres.
- There is no complicated lining up, nothing to aim the Sensor at.
- Most are Battery powered.
- Multiple PIR’s can normally be used with one Alarm.
- They are usually a lower cost than some other solutions.
Negatives:
- They can detect small ground Animals or Flocks of Birds (if they are not positioned correctly, or the right model is chosen).
- They will be activated by large Animals such as Deer & most Dogs.
- The Sun can in some instances trigger them very early or late in the day (if they are not positioned with thought).
Laser Beams:
Positives:
- They can normally protect wider areas (100 metres or more on some models).
- They are far less likely to have False Alarms.
- They are a very narrow Beam making them suitable for monitoring a Perimeter or Fence line.
- Multiple Beams can often be used with one Alarm.
Negatives:
- They are more difficult and can take more time to set up.
- They are normally more expensive.
Vehicle Probes (underground covert probes):
Positives:
- They are designed to only detect Vehicles or moving Steel (so ideal for locations with large animals present).
- They are normally fitted underground (so can be invisible to intruders, or at least far less obvious).
- They can be fitted under Steel Gates (being only triggered if the Gate is opened).
- They can be connected directly with Diallers to make ideal covert Vehicle Alarms.
Negatives:
- They are more difficult and take longer to set up.
- They are normally a higher price than a PIR.
- The detection range is less than a typical PIR or Laser Beam.
Gate Alarm (magnetic gate contact):
Positives:
- They are designed to only detect a Gate being opened (so ideal for locations with large animals).
- They can be fitted to most types of Gates.
- Ideal for large filled in Gates (where the contact cannot be seen).
- Ideal for Gates that are not locked during certain times of the Day.
Negatives:
- They are more difficult and take more time to fit.
- They can be bypassed by a professional Burglar (but this can be greatly minimised to where and how they are fitted).
There are no perfect scenarios of what Sensors to use, quite often the best approach is to use a combination of the products listed above, therefore it is important that you initially choose a model of Alarm that can cover all the potential options you may require.
