Today, the market is full of various advanced driving assistance systems. Some of these systems utilize sensors, while others rely on cameras. Most new drivers have various questions regarding these camera lenses. One of these questions is about their recording, for instance, loop recording?

You might have seen the term “loop recording” on many driving assistance systems. It is also associated with other cameras. But what does it really mean? Let’s find out all about loop recording in this detailed guide!what-is-loop-recording

What is Loop Recording?

Loop recording is the process of continuously recording audio or video to a memory unit. This memory unit can be an SD card, tape, or a live server. The prime example of loop recording can be a live sports broadcast. It utilizes multiple cameras sending video feed to the server, showcasing it live to the audience.

As you may have guessed, loop recording is not limited to just video. In many scenarios, people also record audio continuously to a tape. One good example of that would be scientists audio-logging their day-to-day activities.


How Does Loop Recording Work?

Now, we know what is loop recording. But the question remains, how does it work?

Loop recording requires two components to work, including a camera/audio source and a memory card. When it activates, the recording unit sends a live feed to the connected memory. But what if there’s no more space? Then, the loop recording automatically overwrites the oldest video available in the storage. This way, it continues to send its live feed without any interruptions.

Which Cameras Have Loop Recording?

First, let’s start with the basics. Everyone has seen CCTV cameras in buildings. Their job is to keep an eye out for enhanced security. Thus, they have to work 24/7 continuously without any interruptions. That is why they utilize the loop recording mechanism, sending video feed live to its server and the viewing channel.


But dash cameras have also been utilizing loop recording for many years. Today, you will find this option in almost every dash cam in the market. Moreover, other similar driving assistance systems also have loop recordings. That includes the likes of:

In many driving safety systems, you might hear the term time lapse. So, what is time lapse? Well, it is another name for loop recording in modern systems!

4 Reasons Why Loop Recording Is MUST in Dash Cameras

Loop recording has become a common feature in almost every modern dash camera. But why is that? Let’s look at some reasons why it is a MUST:


1. Uninterrupted Recordings

Road accidents occur when you least expect them. Mostly, you can not take any proactive actions to avoid crashes. However, what you can do is to prepare for them throughout your driving journey. That is exactly what loop recording does.

Generally, it activates as soon as you start your dash camera. In some models, you might have to turn on loop recording manually. Either way, once it starts, it doesn’t face any interruptions. That means it can catch footage of a crash, making it useful for things like insurance claims.

2. Insurance Benefits

Generally, insurance companies try their best to not let you win any claim. That could even mean involving the court. However, you wouldn’t have to worry if you have the required evidence.

Loop recording offers the ultimate benefit of video evidence. You can use it to waver off false insurance claims and disputes. Furthermore, the video can also come in handy in accident situations. That is when the other party is blaming you for a crash. You can use the evidence by presenting it to law enforcers.

Another thing to consider is that most modern insurance companies offer exclusive benefits for vehicles with dash cams. Thus, a dash camera with loop recording can provide monetary advantages, too!

3. Aftermarket Customization

Dash cams are generally available in aftermarket models. These systems can be easily retrofitted into your vehicle. The best part is that you can customize these aftermarket dash cameras according to your needs. And that also goes for loop recording!

Loop recording is a customizable feature in advanced driving assistance systems. You can change the video quality, duration, and many other settings. Secondary features like brightness, exposure, and languages can also be tailored to your requirements.

4. Automatic Space Management

If you have a computer or smartphone, you would know the hassles of storage management. You have to find older files and delete them manually. But that’s not the case with loop recording. It does it automatically!

Loop recording automatically detects the oldest video in your storage. Then, it overwrites that file with a new recording. So, it can continue to record live footage without storage problems.

Another good thing is that you can also change the SD card in most dash cams. This way, loop recording starts saving its video feed to the new memory unit without any errors.

Key Benefits Of Loop Recording

The loop recording feature in ADAS comes with a variety of features. Let’s look at them to provide a clearer picture:

  • Loop recording requires minimal human input. Once activated, it records and manages memory automatically without your interference.
  • With loop recording, the driver can drive stress-free, knowing their dash cams are working without interruptions.
  • You don’t need to change your SD cards frequently. That’s because loop recording can automatically delete older and unwanted videos. So, you spend less bucks on memory units.
  • Most dash cams allow you to change loop recording video settings. This way, you can customize it according to your preferences.
  • Today, loop recording is available in a variety of advanced driving assistance systems. That means you don’t necessarily have to buy a dash cam. Instead, you can buy the one that suits you and your vehicle the most.
  • Since most ADAS are available for all vehicles, loop recording is also compatible with trucks, buses, and emergency vehicles. Thus, professional drivers can also use it!

4 Things to Consider When Buying ADAS with Loop Recording

Knowing what is loop recording on camera is not enough to buy a suitable ADAS. Many other factors can also affect your purchase. Let’s look at them one by one:


1. Video Quality

Most dash cams today offer a video quality of 720p or 1080p. Although it is the standard option, you will also find 4K or 8K video quality. However, that can affect the loop recording factor. That’s because the higher the video quality, the more space it can consume.

Let’s say an SD card of 32GB stores 5 full-length recordings of 720p. So, the same card will only store about 1-2 full-length recordings of 4K video resolution. The safest bet is finding the right balance between cost-effectiveness and optimal video quality.

2. Memory Unit

The memory unit is the standard SD card in most cases. Generally, it comes with a capacity of 32 or 64 GB. However, modern systems might have 128 or 256 GB capacity. As you may expect, these memory cards will be more expensive. Hence, you won’t be able to change them frequently.

Consider buying an SD card according to your driving habits. If you don’t drive frequently, a 32 or 64 GB card will be enough. In contrast, professional drivers will require greater space capacity. Otherwise, the loop recording will overwrite their videos more frequently, causing it to delete even important recordings.

3. Video Duration

One thing that is often overlooked is the video duration. How long can your ADAS continue its loop recording? Always ask this question from the manufacturer before buying any ADAS. Remember that the standard duration is loop recording 5 minutes.

However, professional and commercial drivers will need a longer video duration. That’s because they are more frequently on the road than personal drivers. While on it, also consider other video functions. That can include brightness/exposure adjustment, multiple-language support, night mode, weather-resistance, etc.

The best setting for loop recording dash cam can vary from driver to driver. So, review your driving habits, personal preferences, and budget to find the best option.

4. Advanced Features

While loop recording has many benefits, it is not the only feature to look for in an ADAS. In fact, it is mostly one of the primary features in dash cams or digital rear-view mirrors. Consider choosing an ADAS that offers other benefits besides loop recording.

This way, you can get a cost-effective solution, utilizing multiple functions and maximizing your safety on the road.

What are some advanced features to consider? Here are some examples:

  • GPS Navigation
  • Automated Braking
  • Parking Assist
  • Lane Keeping Assist
  • Wi-Fi/Bluetooth Connectivity
  • Collision Warning
  • Multi-Camera Support
