Stop Intruders in Their Tracks: Choosing the Right Commercial Motion Detection System

Over 42,500 burglaries occurred in the U.S. in 2023, targeting businesses and commercial spaces. Research also reveals that retailers have lost over $100 billion to theft, so keeping your business burglar-proof is key to protecting your bottom line. The right commercial motion detection system can help keep intruders off your property and lower your insurance premiums.

What Is Motion Detection?

Motion detection is the process of identifying changes in an object’s position in a specific area. Motion detection technology operates by sensing changes in energy levels in its environment and translating them into a desired action. The energy that motion sensors rely on includes infrared heat, sound and light.

Why Is Motion Detection Important for Businesses?

Motion detection is an essential addition to a security system, thanks to five key benefits:

• Deterrence: Having a security system for your property is a proactive protection strategy that can discourage intruders. In fact, 60% of convicted burglars have confessed that they would avoid properties with visible security systems.
• Early detection: Motion detection systems can also provide swift alerts in the event of unauthorized activity. With an advanced system incorporating two detection types for heightened accuracy, you will know when intruders wander onto your property.
• Verification: You can pair your system with video surveillance to confirm every alert visually. By adding video verification, you can determine both the threat and its nature, informing an adequate response.
• Reduced losses: Equipping your commercial space with precise motion detection can help protect your business from criminal activity. By discouraging intruders, security systems help prevent theft, vandalism and breaches.
• Lower premiums: With advanced security, your business may pay lower insurance premiums due to the reduced risk.

Types of Commercial Motion Detection Sensors

There are five different types of commercial motion detection sensors:

Passive Infrared (PIR) Sensors

PIR sensors rely on infrared energy emitted by objects to detect movement within their line of sight. These sensors function through a specialized lens called a Fresnel lens, which focuses the infrared radiation from objects onto the pyroelectric sensors within the device.

When an object enters the sensor’s detection zone, the radiation captured by the two pyroelectric sensors in the PIR device is imbalanced. This energy change triggers a predetermined action, like turning on the alarm.

Passive infrared sensors are widely available and among the most affordable options. Since these commercial motion detection devices capture energy rather than release it, they are also energy-efficient. However, they do have their limitations. They are susceptible to false triggers, especially in hot weather.

Microwave Sensors

Unlike PIR sensors, which rely on energy emitted by objects around them, microwave sensors release electromagnetic waves to detect motion within their range. These sensors emit waves at a specific frequency, which are reflected back to the sensor.

When a moving object enters the sensor’s detection zone, the frequency reflected shifts. This change in frequency triggers an alarm or another preset alert action.

Microwave sensors offer a longer range, with some possessing a 360-degree detection zone. They are highly sensitive devices that can capture movements that other sensors miss. However, their superpower can be their kryptonite if not installed by an expert commercial security services provider. Couple their sensitivity with their ability to penetrate through walls, and you may have frequent false triggers.

Ultrasonic Sensors

These commercial motion detection systems work by emitting an inaudible sound frequency. The frequency bounces from the nearest object back to the sensor, which then calculates the total flight time using the speed of sound. In the presence of a moving object, the time the sound is reflected will be shortened. This time differential will trigger an alarm.

Ultrasonic sensors can detect motion in multiple environments, including enclosed spaces. While they are exceptional motion detection devices, their limitation is that they can register differences occurring from the slightest vibrations within their environment.

Dual-Technology Sensors

Dual-technology sensors heighten accuracy by requiring two types of motion detectors to confirm movement. Instead of relying on a single type of sensor, these sensors pair PIR and microwave detection systems. Before an alarm is activated, both sensors need to be triggered.

This dual technology reduces false signals and offers reliable performance. The downside is the cost of the technology. Dual sensors are more expensive than single-technology sensors.

Video Motion Detection (VMD)

One of the most advanced systems, VMD software relies on sudden pixel changes in video frames to confirm movement. The system ignores learned backgrounds or changes that occur over time, like shadows shifting. Once movement is confirmed, the system triggers a desired action, like recording or sounding the alarm.

Some advanced software is equipped with advanced diagnostic technology to enhance accuracy. To prevent false alarms, these commercial security systems may feature tracking capabilities that allow them to ignore people or cars driving by. VMD offers visual verification alongside motion detection, providing a superior detection system. Some models also come with advanced analytics that offer granular data about the movement. Much like dual-technology sensors, VMD software is expensive.

Factors to Consider When Choosing a Commercial Motion Detection System

Every business is different and requires a solution that meets its unique needs. The most advanced solution may not be the best option for your business, considering budget and environmental conditions. Here are a few factors to consider when deciding how to choose the best motion detection system for your business:

Coverage Area

Consider your key concern areas. Do you need coverage over a large expanse or only in a specific area? Understanding your coverage area will help you determine the kind of investment to make. It may help to connect with a security expert to help you choose an ideal solution for your space. For example, microwave sensors could be the perfect solution if you need sensors in your warehouse due to their large range and 360-degree coverage capability.

Sensor Sensitivity

Sensitivity is a business-specific consideration. There is no one-size-fits-all approach to sensor sensitivity. Try to find a detection solution with adjustable sensitivity — this feature will allow you room to test which setting fits your unique needs.

Environmental Conditions

Your environment plays a significant role in your system’s accuracy. Environmental factors like traffic, heat and humidity affect its functionality. For businesses located in high-traffic zones with a lot of noise, an ultrasonic sensor is not the best option. However, a dual-technology sensor can work well in these areas.

Integration With Existing Systems

Before purchasing a new motion detection system, determine its compatibility with your current safety systems. Will your motion sensor integrate with your alarm or video surveillance system? If installing your new software requires a complete system overhaul, it is not a good investment for your business.

Power Source

Another factor to consider is your commercial motion detection system’s power source and energy efficiency. The passive infrared system is the perfect solution for business owners who prioritize energy savings. This system can even run on batteries.

Budget

The amount you are willing to spend on your system is another key determinant of the type of device you can get. If you have a comfortable budget, consider the VMD or dual-technology system. If you need fast, affordable installation, the PIR system is the answer.
