Best Infrared Security Fence – Smart Security Surveillance Systems

Infrared fence detectors are perfect security sensors to ensure that your premises are secure by guiding entry points. These sensors are usually installed in aisle, balcony, windows, and gates. Unlike electric fences, infrared fences use invisible barriers that detect intrusion. These fences have long guarding range and detection and can be easily installed.

The best-infrared security fence will notify you before an intruder enters your premises and not after. Most companies that design motion sensors recommend a system that will focus on guiding the entry doors. The logic behind that is that when an intruder enters through the window or the door, they will trigger an alarm when they pass in front of motion sensors. However, an intruder will have already entered the house, and they can easily take what they want and run away. Some intruders can also bypass some of the motion sensors without setting off an alarm.

An infrared security fence focus on all entry points to premises, and it will sound an alarm before an intruder enter your home. The chances are that the intruder will free due to the alarm and nothing will be compromised. Best infrared security fences will incorporate motion detection technology that reduces false alarm caused by pets, animals, weather or rain.

These infrared fences have a weatherproof design and can be installed outside or inside. This type of security system is a professional solution for protecting against exterior and interior intrusion.

Infrared security fences when used with security cameras offer complete home security. Everyone makes home security a priority and people can go with different methods, but with the development of technology, infrared security fences gained popularity.

The infrared beams offer flexibility. They can be placed in different locations and different heights.

How infrared fence detector works?

An infrared sensor usually come in a pair, which includes a transmitter and a receiver. The infrared transmitter emits infrared light, and the light is directed to the receiver. This is a working principle of infrared sensors. The receiver and the transmitter are usually installed directly opposite each other, and invisible infrared beams protect the region between them. When an intruder crosses them infrared beam, the beam will be interrupted. The receiver then triggers an alarm and then send alarm signals.

Active infrared detectors use an infrared technique that offers accurate motion detection than passive infrared sensors. Also, these fences have sensors that utilize pulsating code to eliminate light sources from car headlights, sunlight and lightning flashes. The receiver will only react to interruptions in the pulsating beam, and other light sources won’t affect the receiver.

Why should you invest on an infrared fence?

Infrared security fences are a great and cost-effective way of keeping intruders off from your premise. Also, it offers better security should they break in. You will be alerted by alarms, but an intruder won’t be aware that they have triggered alarms until it’s too late.

Choosing the perfect infrared fences

For you to pick the perfect infrared security fence, consider these two things: the detection range and the number of beams. Most infrared beam sensors can have 10, 8, 6, 4, 3, or 2. As the number of beams increases, the detector’s height also increases. A door and a single window would require about 2 to 4 beams fence sensors. For doors, windows, and balconies, it will require about 6 to 10 beams.

Detection range should also be considered when picking the right infrared security fence. Infrared detectors aren’t like other detectors as the distance between the receiver and transmitter should be exactly as the rated one. For instance, if the detection range is 40 meters, users will need to pick a 20-meter infrared fence detector. However, some infrared detectors allow for adjustment of intensity, and this allows for changing detection range.

Infrared security fences pros

Have a physical fence is useful, but such fences don’t have the same appeal. For instance, they have high installation cost. A lot of material would be required to put up such a fence. Also, they aren’t that secure as one can easily climb over and may not be seen. Electrical fences are also costly as they run off an enormous amount of electricity. However, Infrared have many advantages which include:

  • Relatively cheap unlike other fence types
  • Offer long-range detection and can be applied to large area
  • They are high quality
  • They operate in real time and pick up movement, therefore useful in variety of circumstances
  • Most fire departments use the detectors are they help in seeing through smoke.
  • Infrared detector can detect living and non-living objects

Infrared security fence cons

  • Sometimes these fences can lead to inaccuracy since the detectors detect images depending on the difference of temperature between objects and cannot detect the difference in objects with similar temperature range.
  • An infrared fence won’t be effective when someone under pretense enters the building. Intruders could disguise themselves as utilities, salespersons, etc.


Current trends in security systems concentrate on systems that detect intruders before they enter a premise. Since the problem starts when the perimeter or boundary of the property, a system that can detect a problem before it starts is more effective than the one that works when the intruder is already in the house.

Every homeowner will always want to protect their home when they are away or when sleeping. Most security systems such as security cameras and alarm systems can be easily operated. Some security systems can be troublesome to homeowners as some needs to be armed and disarmed while others are costly.

Larger facilities combine different security systems such as infrared fences, electric fencing, electronic beams, CCTV cameras and motion sensors. Small areas such as commercial spaces and homes may be good with perimeter infrared security systems.
