Key Takeaways:

Cargo door sensors send instant notifications when cargo is opened outside the designated loading/unloading location.
Record every cargo door opening with timestamp and GPS location for accurate audits and investigations.
Combine door sensors with Live Vision cameras for 24/7 real-time visual surveillance of cargo.

Imagine receiving a driver report that your delivery truck was broken into while in transit. Goods are lost, customers are disappointed, and the company's reputation is at stake.

As a logistics fleet owner or manager, you may encounter many challenges, from unauthorised cargo smuggling, damaged cargo contents, to theft, all of which can cause losses for your company.

This time, we'll introduce the solution to all of these problems: cargo door sensors. Learn more about how these sensors work and how they can benefit your company's needs.

What Is a Cargo Door Sensor?

A cargo door sensor is a type of sensor used to detect the opening and closing of doors on a vehicle's cargo hold. This sensor can help you identify suspicious behavior, such as opening the cargo door before reaching its destination.

Combined with a GPS tracker, you'll know the location, date, and time the door was opened and closed. With automatic notifications, you can also receive real-time alerts when the door is opened outside its designated area.

How does it work?

Typically, these sensors use magnetic devices that attach when the door is closed and detach when the door is opened. When the sensor detects door opening or closing, a signal is immediately sent to the fleet management system.

This allows data to be recorded in the system and can be viewed on the dashboard and in vehicle reports. You can also configure notifications if cargo is opened outside the destination area.

What are the Benefits for Business?

Some of the benefits you can get if you use this device include:

1. Tracking Cargo Theft and Misuse

A cargo door opened in an inappropriate location could indicate theft or misuse of the vehicle's cargo for side shipments (smuggling). You can estimate the amount of cargo being unloaded by the duration of the door's opening.

If the cargo is open while the vehicle is in motion, the fleet manager can immediately contact the driver to inspect it. In this case, the door may not have closed properly or there may have been a theft, such as the "bajing lomcat" (Jack Squirrel Jumping) case that still occurs frequently in Indonesia.

2. Maintaining Product Freshness in Refrigerated Cargo

Opening and closing refrigerated cargo doors can affect temperature, especially when shipping food or beverages. To maintain product freshness in refrigerated cargo, you'll need to install this sensor in addition to the temperature sensor.

Notifications can be sent every time a door is opened and closed to ensure that refrigerated cargo is not left open for too long. This prevents temperature fluctuations, energy waste, and product quality degradation in the cooler.

3. Minimise the Cost of Losses in Shipping

By reducing the risk of theft, misuse of cargo, energy waste, and product damage in refrigeration, you can minimise shipping losses. The benefits will be significant even if not all of your cargo is equipped with these sensors.

Imagine the return on investment you would receive if all your cargo vehicles were equipped with these sensors. With optimal fleet management, these benefits can be maximised.

4. Improve Customer Satisfaction

Combined with a GPS tracker, this sensor ensures the reliability of your company's fleet delivery service. With real-time notifications when a door opens, you can take immediate action to prevent any potential cargo security risks.

Your customers' business will run smoothly, with a secure supply, as orders are delivered in the correct quantities, with no lost or damaged items. Customer satisfaction and trust in your service will increase, as will your company's image and profits.

Cargo Door Sensor from Cartrack Fleet Management

Cargo Door Monitoring is an add-on or additional feature you can add when subscribing to Cartrack's Fleet Management System. You can install this sensor on trucks with both side and rear doors.

The data you can find out includes:

Date and time when the door was opened
Location of the door opened
Date and time when the door was closed
Duration (from when the door is opened until it is closed again)

Data will be available as graphs on the dashboard or tables in automated reports. You can also set up notifications when cargo doors open or close, combining this with the Geofence feature.

Cargo Door Sensor Prices and How to Purchase Them

You can get this sensor by subscribing to Cartrack's Fleet Management System, starting at Rp150,000/unit/month. Features you'll get with this subscription include:

Real-time GPS tracking
Trip history
Find the nearest driver
Idling
Geofence dan Point of Interest (POI)
Driving behavior (speeding, sudden braking, sharp turns)
Automatic reports (including carbon emissions reports)
Machine working hours
Two additional sensor options

Can I just buy the sensor without subscribing to the Fleet Management System?

It's important to note that sensors are simply devices whose functionality and settings require a specific system or software, such as a Fleet Management System. Without this system, the sensor cannot display data, and you cannot configure notification and geofence settings.

So, to be able to monitor cargo doors, you must first have a system capable of accommodating its functions.

Conclusion

By using door sensors on cargo, shipping risks can be reduced, security increased, and customer satisfaction increased. Equip your shipments with cargo door sensors today. Fill in your details in the form below so our staff can contact you and provide you with the best Cartrack offer.

Frequently Asked Questions (FAQ)

How much does it cost to install a cargo door sensor?

These sensors are usually included as add-ons to Fleet Management Systems, such as those provided by Cartrack. Therefore, if you want the sensors, you'll also need a subscription.

Is this sensor resistant to vibrations from the vehicle, so it won't cause errors?

Yes, these sensors are generally resistant to vehicle vibrations as long as your vehicle's doors are still functioning normally. In some cases, such as if the door is open but not fully closed, the sensor will still detect it, allowing you to perform a check.

Is it true that cargo door sensors can help with insurance claims in cases of theft?

Yes, data from these sensors can be used to support cargo insurance claims in the event of theft. You'll still need to provide additional evidence to ensure your claim is accepted.
