Laser beam sensor intrusion detection

Types of laser beam sensor intrusion detection

Many different kinds of laser sensor equipment are used to detect intrusions. Several laser types exist. Each works well in a certain way. Knowing the difference between these options is very important. This is especially important for people with security-related businesses.

Local incident detection systems avoid stealing valuable assets. They also protect important sites. There are many types of these systems. Choosing the right one is crucial. This decision is vital for safety in many places.

Some spaces may require unique types. Installing the correct equipment decreases safety risks. It also ensures high performance. Below are five types of these products.

Laser displacement sensor

This sensor detects the distance or any tiny changes in distance to an object. A laser beam will be shone on the object's surface. It will then measure how the spot on the surface moves. This is done by noting the distance from the sensor to the surface. If the object is static, the distance will remain the same. But if it moves, even a tiny bit, it will change! The sensor will note this change.

The fine measurements that this sensor can provide make it well-suited for tasks. It can detect any small shifts in position, and this can prevent intruders from getting into secure areas. The sensor can also detect any slight changes in the space that could mean a possible intrusion, which is why it is used.

Time of flight laser sensor

This detects laser range by studying the time taken for a laser pulse to return after reflecting off a surface. It works by shooting a laser beam at a target, like a wall. Then, it measures the time the beam takes to bounce back. If nothing is in between, the time count will be the same because the beam will travel in a straight line. But if an intruder comes, the beam will bounce off them too.

The longer the beam takes to come back, the further away the sensor is from the target. So, by measuring the time, the sensor can calculate how far it is from the wall. That is why, even after so many years, this sensor remains a popular choice.

Compact laser sensor

These sensors are small electronic equipment that intruders can sneak past unseen. Their compact sizes mean they can be installed in tighter areas or hidden more easily than larger models. This makes protecting secure zones more challenging. They carry out their job effectively, even in small sizes. Their important work is detecting movement amid laser beams in security systems.

Dual technology laser sensor

This combines laser detection with another technology, such as motion sensors. Employing two methods fortifies security by ensuring that an intruder must trip both sensors to activate an alarm. Doing this cuts down on false alarms. It also gives a backup way to guard important areas.

Long-range laser sensor

This is used when wide security zones need to be monitored. These can shoot a laser beam over many hundreds of meters. They work well on tall fences or wide-open spaces. Their ability to have long range means they can track over long distances. It keeps crucial sites secure from any distance.

Industrial laser sensor materials

The materials used to make these sensors are really important. They will affect how the sensors work and how well they will stand up to their job. Here are some key sensor parts and the materials they are made of.

This is a list of laser sensor intrusion detection materials.

Transmitter

LDs or laser diodes are commonly used as light sources since they emit strong, focused beams.

Lens system

Glass or optical plastic lense systems to focus or expand a laser beam will usually have high clarity and low distortion.

Housing

The sensor's casing is usually made from weather-resistant plastics or metal alloys like stainless steel. These materials protect all internal parts from dust, water, or vandalism.

Photodetector

Most photodetectors are made from semiconductor materials like silicon or indium gallium arsenide (IGA). These sensitive elements are the response area where the laser beam will hit.

They then convert that laser light into an electric signal. This is what then allows the equipment to detect intruders.

How to choose laser beam sensor intrusion detection

Many factors will come into play when choosing these devices. Buyers have to think about what spaces the sensors will protect. They will also have to consider the environment the sensor will be used in and its operating range. Below is a list of things to keep in mind.

• Security zone

  Different types of laser sensors are made for different spaces. Some work well for tiny indoor spaces, while others are ideal for huge outdoor areas. Knowing the intrusion detection zone first will help pick the right sensor.

  For instance, large sites call for long-range laser sensors capable of covering wide distances. But if the area is small or has many walls, a compact laser sensor may work better.

• Laser type

  Each laser of varying wavelengths will work better in different environments. A laser with a short wavelength will work from a close range. This is so because it can easily be diffused by obstacles like smoke or dust. On the other hand, one with a long wavelength will work from a long range. It is more likely to withstand such environmental elements.

• Environment

  Sensors used outside should be strong enough to handle any weather changes, such as sunlight or rain, and anything like wind or even animals. That is why many outdoor laser sensors have a weatherproof casing to secure them from such natural destruction. Indoor sensors do not require this as much. Many have a more compact design made for indoor use.

• Mounting position

  This determines how an intrusion detection device will perform. Laser sensor systems have to be mounted in specific ways to work right. For example, a great vantage point to shoot a laser beam across a zone must be found. Mounting it at the correct angle will also be important.

• Alarm integration

  Choosing a laser sensor that will easily mesh with whatever alarm system is already in place is vital. Many manufacturers make their sensors compatible with a range of alarms. This cuts down on work when setting everything up.
