In-car cameras, also known as dash cams, are devices that record video footage of the road while driving. They are primarily used for safety and security purposes, providing evidence in case of accidents, insurance fraud, or theft. There are several types of in-car cameras, each with unique features and advantages.
Single-lens dash cam
These are the most common types of in-car cameras. They have one lens that records the road ahead. The field of view is usually between 100 and 140 degrees. Some come with GPS, which tracks the speed and location of the vehicle, while others have Wi-Fi to transfer the footage to a smartphone.
Dual-lens dash cams
They have two lenses, one pointing forward and another looking backward. This gives a complete view of the surroundings. The front camera records the road ahead, while the rear one captures traffic behind. Dual-lens dash cams are great for understanding the context of an incident, as they provide footage from both directions. They have a wider field of view, about 120 degrees for each lens. Some models also include GPS and Wi-Fi.
3-channel dash cams
These in-car camera systems have three channels: one for the front, one for the rear, and one for the interior of the vehicle. They are ideal for taxi drivers or parents with teenage kids. 3-channel dash cams provide comprehensive coverage and record all activities inside and outside the car. They usually have a higher resolution and advanced features like night vision and parking mode.
4K Ultra HD dash cams
These in-car cameras offer the highest video quality. The 4K Ultra HD resolution captures more details than lower-resolution models. This is particularly useful for identifying license plates or faces. They also have advanced features like GPS, Wi-Fi, and voice control. However, they consume more storage space and require a high-capacity memory card.
Night vision dash cams
Night vision is a crucial feature for in-car cameras. They use infrared LEDs or enhanced low-light sensors to record clear videos in poor lighting. Night vision dash cams are excellent for driving at night or in areas with low visibility. They ensure safety and security, even in darkness. Some models also combine with dual-lens or 4K Ultra HD.
Wi-Fi and GPS-enabled dash cams
These in-car cameras have built-in Wi-Fi and GPS. The Wi-Fi connection allows users to transfer the footage to a smartphone or sync it with an app for easier control. The GPS tracks the vehicle's speed and location, adding context to the recorded video. Some models also come with Bluetooth for connecting to other devices.
Action cameras
These in-car cameras are portable and versatile. They can be mounted on the dashboard or windshield, like other in-car cameras, to record the driving experience. Action cameras have higher video quality and can be used for other outdoor activities like biking or skiing. They also have Wi-Fi for instant sharing.
Smartphone-based dash cams
These in-car cameras use the existing camera of a smartphone together with a dedicated app to provide dash cam functionality. The app records the driving, and the phone acts like a dash cam. It is a cost-effective solution for basic dash cam needs. However, it requires the phone to be plugged in and the app running while driving.
Resolution
Dash cams have different resolution capabilities. The most common are 1080p, 1440p, and 4K. Higher resolutions give clearer images but need more storage space.
Field of View (FOV)
The FOV is how much the camera can see. A wider angle means more of the road is recorded. But too wide can make things look smaller and be harder to identify. A 120 to 180-degree FOV is typical.
Night Vision
Good night vision is required to record clearly in the dark. Cameras with infrared (IR) can see better when there is little light.
GPS
GPS shows where the video was filmed on a map. It can track speed and route taken. Some dash cams have built-in GPS, while others need an extra module.
Storage
Dash cams use microSD cards to save videos. More storage means recording more hours. Cards come in 32GB to 512GB or more. Look for high-speed cards that dash cams require.
Loop Recording
Loop recording means the oldest videos are deleted to make room for new ones. This way, the dash cam always has space to record.
G-Sensor
A G-sensor detects crashes or sudden stops. It locks the current video to prevent it from being overwritten. This ensures the important incident footage is available.
App Connectivity
Some dash cams can connect to smartphones through Wi-Fi or Bluetooth. An app lets users view live video, change settings and download files easily.
Voice Control
Voice control lets drivers give spoken commands. They can tell the camera to take a picture or start recording without using their hands.
Dual Channel
Some dash cams have front and rear cameras. A dual-channel camera records both areas. It gives more protection by covering the front and back of the car.
Mounting Options
Dash cams come with mounts such as adhesive pads, suction cups, or brackets. The mounting method affects how easily the cam can be attached and removed.
Battery vs. Capacitor
Dash cams run on batteries or capacitors. Batteries can record for a while after the car turns off. But they may overheat. Capacitors handle high temperatures better but have a shorter backup time.

With so many options available, choosing the In-car camera can be challenging. Here are some tips to simplify the decision-making process:
It can be quite easy to replace an in-car camera, and many people can do it themselves. The first step, of course, is to remove the old camera. To do this, car owners will need to consult the user manual to understand how to uninstall the camera. Different models have different installation methods. Some might be attached with adhesive mounts, while others might be attached with screw mounts. If it is attached with screw mounts, car owners will need to have a screwdriver to remove the screws.
After successfully removing the old camera, car owners will need to clean the surface where the camera was mounted. This is important, especially for cameras that were mounted using adhesive. Failing to do this will result in the new camera not sticking properly, and it might fall off.
The next step is to install the new camera. Again, at this point, car owners will need to consult the user manual to understand how to install the camera. They should follow the instructions provided by the manufacturer. For most cameras, this is the stage where they will mount the camera on the windshield or on the rearview mirror. They will also need to connect the camera to the power supply and ensure that the cables are properly installed so they are not visible and do not cause distractions.
After installing and mounting the camera, it is important to check whether it is working properly. Car owners should run a test to ensure that the camera is capturing video footage and that it is working properly.
Some of the tools that car owners might need to install their in-car cameras include a screwdriver, depending on the type of mount used, adhesive pads, and cable management clips. They will also need to have a cleaning cloth to clean the surface where they will mount the camera.
Q1: Do In-car cameras drain the car's battery?
A1: Most in-car cameras do not drain the car's battery, especially those with parking mode. They have a low power consumption rate. Also, if the camera is connected to a power outlet that turns off with the ignition, it won't drain the battery:
Q2: Can one install in-car cameras themselves?
A2: Yes, in-car cameras are easy to install, and one can do it themselves. Many of them come with installation manuals. Besides, there are plenty of tutorials online that guide one on how to install them:
Q3: Do in-car cameras have night vision?
A3: Not all in-car cameras have night vision. However, some have high-quality lenses that can capture footage even in low light. If one frequently drives at night, they should consider getting a car camera with night vision capabilities.
