Are Truck Sensors Better than Cameras? A Detailed Guide

Table of Contents

Are you a professional truck driver? Then, you would know how stressing it is to drive a long vehicle. It requires your undivided attention on the road. A minor mishap can lead to devastating accidents. According to the Insurance Institute for Highway Safety (IIHS), about 4,714 died in truck crashes. Remember that this survey was for 2021. Hence, the number of accidents and fatalities has increased since then. In such a dangerous environment, truck sensors have stood the test of time.

Is it your first time hearing about truck sensors? No need to worry. This guide will walk you through the basics and compare them with another popular solution, cameras. Without any further ado, let’s get started!


What are Truck Sensors?

Truck sensors are driving assistance devices to avoid collisions and fatal accidents. Generally, they monitor the blind spots of the truck. The sensors can handle this job since these areas are unseeable in side-view mirrors. They use radar waves to detect oncoming speeding objects, like cars and other trucks.

What happens is that a truck has more extensive blind spots than ordinary cars. Thus, the danger and severity of blind spot accidents are also higher. These sensors can detect vehicles in a truck’s no zones. Not only that, but they also send alerts to the driver. As a result, you will know when to watch out for your blind spots. Plus, you can always make informed decisions and evade tricky situations.

Truck monitoring and engine sensors were invented around the same time as car blind spot monitors were introduced in 2007. Ever since then, the industry has made many changes to these systems. Modern systems also have additional features, like braking assist and collision avoidance.


Are Truck Sensors Present in Every Truck?

Many people get confused when you talk about truck sensors. Their immediate question is: does my truck have those? You will have to understand a few things about that.

Firstly, there are primarily two types of truck sensors: aftermarket and factory-built. Let’s talk about both of them in detail:

1. Factory-Built Truck Sensors

These truck sensors come pre-installed in a truck model. You don’t need anything else to start using them. Usually, you can read your truck’s manual or contact the company to see if it has sensors.

They are designed specifically for a single model, making them inflexible. Plus, they will require repairs and maintenance from their company’s officials.

2. Aftermarket Truck Sensors

An aftermarket sensor doesn’t come installed in trucks. Instead, you can buy it separately from the market. However, it may come in various models and types. The fundamental differences in these models are detection range, accuracy, installation method, and alert system.

Another thing to note is that aftermarket truck sensors are universal. You can install them in any truck, regardless of the model or company. Also, their spare parts and repair professionals are more abundant in the automobile market. Since they are not designed for specific truck models, they are comparatively more flexible.

Installation & Maintenance of Truck Sensors

You might not know much about installing truck sensors if you are inexperienced with them. However, we will provide all the essential information regarding installation and maintenance. Let’s dig in!

Installing Truck Sensors 101

The installation of truck sensors can vary depending on their model and type. However, here’s what you need to know:

  • Sensors are mounted inside and outside the rear bumper.
  • Alert system mounts on the side-view mirror for easy viewing.
  • Make sure to follow the specific instructions mentioned in the manufacturer’s manual.
  • If you face any installation difficulties, you can always consult a professional.

Maintaining Truck Sensors 101

Do you want your truck sensors to last long? This one-time investment can get you through several years. The key is to maintain them by following the steps below:

  • Calibrate your sensors if you notice miscalculations or wrong alerts.
  • Let a professional inspect your truck sensors after every few months.
  • If you see any error code, make sure to consult a professional.

What are the Types of Truck Sensors?

Here are some types of truck sensors explained in detail:


1. Blind Spot Sensors

Blind spot sensors are the most common type in trucks. Usually, it monitors the right and left no-zones of a truck. Remember that these areas are considered the most dangerous due to their low visibility. Hence, this type can be highly effective and helpful, especially for new drivers.

2. Collision Avoidance Sensors

Immediate rear and forward areas are also blind spots in a truck. A vehicle within a range of 10 ft can disappear due to a truck’s large body. Collision avoidance sensors can handle these spots and provide real-time monitoring.

They utilize a smart algorithm to calculate the outcome of a situation, alarming about potential collisions. You might have seen a Car sensor front, which prevents forward collisions. This system works the same for trucks.

3. Lane Departure Alert Sensors

These sensors are not as common today as most other types. However, they were popular a few years ago. Their basic premise is to help change lanes or turn without casualties. They can trigger a warning if the situation is not clear. This way, the driver can undo their decision, keeping themselves and others safe.

4. Parking Assistance Sensors

Parking can be a challenging task in a heavy vehicle like a truck. It occupies significantly more space than cars and SUVs. Parking assistance sensors can help you park your truck without any problems. As a result, you don’t collide with nearby parked vehicles or objects, keeping your truck protected.

5. Advanced Hybrid Sensors

Advanced truck sensors carry the features of all or most other types. For instance, they can monitor blind spots, trigger collision warnings, and assist with parking. As you may expect, this truck sensor’s price is significantly more expensive than others. They combine different types of sensors to help with various tasks. This way, a driver doesn’t need other equipment.


Cameras vs Sensors – Which Is a Better Solution for Trucks?

Truck sensors vs cameras is an eternal debate on the internet. Many drivers find one more effective, while many others root for the other solution. But which one is the better? Let’s put this debate to an end once and for all.

Let’s discuss the different factors that make a solution useful for truck drivers:

1. Installation

Let’s start with the basics. Installation is the first step after buying a truck solution. Both cameras and sensor systems come with their dedicated manuals. They help understand the ins and outs of the installation process.

However, cameras may require some consultation and professional assistance for installation. That’s because they come with a lot of wiring. You have to install the camera on the truck’s exterior. Then, connect the cables to a central box. Finally, link the box to the display screen. Also, the wiring can ruin the aesthetics of your car’s interior.

Alternatively, sensors don’t have that many cables. Also, they are comparatively easier to install because they mount on a vehicle’s bumper. The alert system mounts easily on the side-view mirror via an adhesive sticker.

2. Accuracy, Range & Effectiveness

Both cameras and sensors have accuracy, a decent detection range, and effectiveness. A camera can provide real-time footage of your truck’s blind spots or other areas. However, keeping up with the output video can be distracting. The camera lens can get dirty or blocked due to weather and outdoor conditions.

A sensor also keeps you updated on your surroundings. It emits radar waves that can accurately detect any vehicle in an area. Moreover, sensors don’t get affected by weather or outdoor elements.

3. Types

Many different types of cameras are available in the market. You will find single or dual-camera systems. Dashcams and rear-view mirror devices also fall into this category.

Similarly, truck sensors also come in a wide range of types. That includes blind spot, parking, lane assist, and collision avoidance sensors. You can also find hybrid ones that combine different features from multiple types.

4. Maintenance

Maintenance can be a hassle with cameras. They can catch dirt, debris, dust, snow, and water. Thus, cleaning them after every long drive is a MUST. While at it, you should also wipe off the display screen for dirt marks.

In contrast, sensors don’t require that frequent maintenance. You should clean them if you notice any error in their accuracy. Calibration can also be a good idea but isn’t a regular requirement.

Final Verdict

Cameras are not the ideal truck sensors replacement as they require more maintenance, have complex installation, and may be affected by weather conditions. However, many people can still find them more helpful.

Overall, sensors are a supreme option. They are more cost-effective, easy to install, weather-resistant, and require less maintenance.
