9 Ways of Outdoor Detection

To prevent intruders from entering your business premises, you take all kinds of measures.
Physical barriers (such as sturdy windows, doors, and locks) and an alarm system.
If you have a site around your property, you can detect intruders even earlier.
They can then still be apprehended before they have a chance to enter your premises.
There are a variety of outdoor detection systems available.
In this article, we list them for you. Detectors are deployed as part of a total intrusion protection system; A system that is aimed at identifying intruders as early as possible, then delaying them for such a long time that the follow-up can take place within the delay time.
These are the basic principles of OSVO, the model developed by Mactwin with which effective burglary protection can be designed.
Detecting it as early as possible preferably starts with the outer shell.
Roughly speaking, we can classify systems for outdoor detection into underground systems, freestanding systems and fence or wall-related systems.

1. Underground Detection System

With an underground system, you can invisibly secure your outdoor area.
An underground detection system works with pressure mats, vibration sensors or hoses filled with liquids and associated pressure sensors.
The invisible system is incorporated into the ground and measures the pressure differences or vibrations that occur as soon as an intruder enters the site.
The measured pressure differences/vibrations are analyzed and, if necessary, converted into an alarm.
These systems will almost certainly detect an intruder; whether the intruder is walking, jumping, crawling, rolling or using gangways.
The systems are insensitive to weather influences, they are low-maintenance and work in almost any surface such as gravel, concrete, asphalt and Stelcon slabs.
They are also suitable for hilly terrain.
However, a lot of excavation work is required during construction.
This makes this form of outdoor detection relatively expensive.
If you opt for an underground system, you should take into account the sensitivity of the system, for example to vibrations from heavy trucks or trains.

2. Energizer system on/on fence or wall

Fences (even existing ones!) or walls can be fitted with an electric fence system quite easily.
An electric fence system incorporated on or in a fence or on a wall prevents an intruder from climbing over the fence or wall; Touching the electric fence gives the intruder a big shock.
At the same time, the electric fence detects that someone is climbing the fence and can sound an alarm.
A disadvantage is that it is a visible system that is also quite easy to manipulate.

3. Microphone cable system on (or in) fence

A microphone cable system works with a cable that is prone to distortion.
Deformation generates a small tension.
A sensor at the end of the cable detects this distortion.
The cable is woven through the (mesh) fencing or can be tied to it.
The disadvantage of this system, which is also visible, is that it is sensitive to vandalism and manipulation, as well as to vibrations.

4. Digital radar system

A digital radar system is easy to install and creates a ‘wall’ of radar waves (microwaves) around your site.
The invisible radar waves detect movement in the area covered by the waves.
Microwaves are not affected by wind, but flying objects can cause an unwanted alarm.
Nowadays, the minimum size of an object to be detected can often be set.

5. Active Infrared System

An active infrared system works on the principle of breaking through the infrared light beam.
A source (actively) emits one or more infrared light beams to a receiver.
If the light rays are interrupted, for example because an intruder passes through the beam, an alarm signal is given.
The range of infrared is large, about 150 – 200 meters.
Because the detection field is narrow, the system is very suitable for narrow areas and to ‘cover’ the façade of a building.
Similar to a radar system, flying objects can trigger an unwanted alarm.
In addition, it is sensitive to weather influences and can suffer from vegetation on the property.
An infrared system is easy to install and inexpensive, but it does require a lot of maintenance.
