Why Use a Capacitor Dash Cam?

Dash cams provide security and backup in the case of accidents, break-ins or other unusual events. However, batteries tend to lose storage capacity over time, usually within one to two years. No truck owner wants the battery to die at the worst possible moment. Capacitor technology allows capacitor dash cams to retain full energy capacity long after batteries are experiencing short lives.

At the same time, when a dash cam sits in a parked car in a hot climate, batteries can quickly overheat, leading the dash cam to shut down. Capacitors can withstand very high temperatures, ensuring that your dash cam is working when you need it. 

How Does a Capacitor Dash Cam Work?

A capacitor dash cam records and stores video footage inside and outside the vehicle. Some cameras stop recording when your vehicle parks, but this is not the case for capacitor dash cams. These dash cams record when your vehicle is parked and in motion. Dash cam video footage gets stored on an SD memory card. Most dash cams will give you the option to loop the video or re-write over video footage when your SD card becomes full. Some dash cams offer exceptional low-light cameras, GPS apps and other features, such as long-term video storage of events like accidents. 

Benefits of a Capacitor Dash Cam

  • Larger storage capacity: More storage capacity means more footage before your dash cam loops existing recordings.
  • Heat-resistant, even at high temperatures: You won’t have to worry about the dash cam getting overheated and then not recording properly.
  • More reliable than batteries: Batteries can die out at the most inconvenient times. Capacitor dash cams are more reliable.
  • Usually available in higher-resolution and higher-quality cameras: A higher-quality camera makes it easier to see and understand the footage. Blurry images can make it harder to prove your truck did not cause an accident or to identify thieves.

What to Look for With Capacitor Dash Cams

Some dash cams are better than others, but it’s important to find the right dash cam for you. Before you search for a dash cam, identify all of the features you need. Popular features include parking mode, memory card, wireless connectivity, video quality and ease of setup. Here’s what you’ll want to consider.

Video Quality and Coverage

Most truck owners prefer two cameras instead of one, and some dash cams provide three cameras for additional flexibility. You should also consider if the cameras are external or internal. You’ll need to decide which camera angles are essential for you, as well as the physical video quality. 

While you may not need 4k resolution in most cases, it is becoming the industry standard. This resolution offers a clearer view of small details, like license plate numbers or faces. Look at how the camera performs in low light and night mode capabilities to get the best coverage. 

Easy Installation and Setup

The best capacitor dash cams are easy to install and include all required hardware. Low-end dash cams lack ease of mounting or intuitive setup. Low-end dash cams with complicated installation and setup may be cheaper, but a frustrating installation process or incorrect setup can turn a cheap dash cam into an expensive one.

We narrowed our list of top dash cams to ones with easy installation. If you look for dash cams off this list, you should check other user reviews to ensure the dash cam you choose has an easy setup process. 

Parking Mode

Parking mode puts your dash cam into hibernation, but it can begin recording footage in an instant when certain events occur, such as when a person or vehicle approaches your vehicle. 

This feature allows you to make insurance claims even in the case of hit and runs or other vehicle damage incurred while parked. 

Heat Resistant 

The heat resistant feature is essential for drivers during the hot summer or people driving in the south. Most capacitor dash cams can resist heat up to 150° but double-check the information on each individual dash cam. 

Memory (SD Card)

What is the maximum memory card available for the dash cam? Do you need to store a large volume of video footage? The best capacitor dash cams have a memory card or SD card capacity ranging anywhere from 64 GB to 512 GB.

Wireless Connectivity

The best capacitor dash cams offer wireless connectivity for GPS navigation and app connections.  Wireless connection is not a universal feature in capacitor dash cams. If you need this feature, make sure the dash cam you choose has Wi-Fi connectivity. 

Extra Features 

Extra features include the number of cameras, the type of loop recording and whether the camera automatically saves video from an accident. However, you shouldn’t confuse more features with better quality. Dash cam companies add new features to their products frequently, but that doesn’t necessarily increase the product’s value. Focus on excellent performance and the core features before selecting useful extras like GPS or speed limit indicator. 

Get the Right Capacitor Dash Cam for Your Truck

Capacitor dash cams offer numerous advantages, but drivers have many options. You may browse through several dash cams before finding the right one for you. Keep in mind what features you need in a dash cam and narrow the list. This process will help you find a suitable dash cam that provides extra safety measures.


How long can capacitors hold charge?

A capacitor can last 10 to 20 years before replacement, depending on how often it is used.

What does the super capacitor do in a dash cam?

The supercapacitor stores and protects footage in the dash cam.

Are supercapacitors better than batteries?

Supercapacitors are more reliable than batteries at recording footage and staying powered throughout the drive.
