The Best Dash Camera: What to Look for

There are many important things to keep in mind when choosing the best dash camera. Each model is a bit different from another, and some of them have some features that you do not find in competing models.

Dash video cameras vary in price and usually the price reflects the number and quality of the present functions.

Cheap models have few features and offer lower resolution, while more expensive models usually offer advanced features such as Wi-Fi connectivity, GPS antenna, wider shooting angle, and a better image sensor.

Video Quality

Video quality is perhaps the most critical factor when choosing a dash camera.

After all, the main purpose of having a dash cam is to record clear and detailed footage of your journey, which can be essential in the event of an accident or dispute.

Resolution: The resolution of a dash camera determines the clarity of its recordings. Standard resolution starts from 720p (HD), while a more advanced option is 1080p (Full HD). However, in recent years, dash cams offering 2K (QHD) and 4K (Ultra HD) resolution have emerged, offering crisper, more detailed footage.

A higher resolution dash cam can capture finer details like number plates or faces, even at a distance. However, these high-quality recordings also consume more storage space, so consider a dash cam with a larger storage capacity or efficient compression technology like H.264 or H.265.

Frame Rate: Besides resolution, the frame rate also impacts video quality. Measured in frames per second (fps), a higher frame rate provides smoother video playback. Most dash cams record at 30 fps, but some high-end models offer 60 fps, capturing more frames per second for smoother footage and better clarity when paused.

Bit Rate: This is the amount of data the dash cam records per second, and it has a direct impact on video quality. Higher bit rate equals better image quality, but also larger file sizes.

Night Vision

Night vision is an essential feature for a dash camera, considering a significant number of accidents occur during nighttime, dawn, or dusk when visibility is limited.

Infrared (IR) Sensors: Some dash cameras are equipped with IR sensors that use infrared light to illuminate dark surroundings, useful for interior cabin recording in particular.

Wide Dynamic Range (WDR) and High Dynamic Range (HDR): Both technologies help improve the camera’s ability to handle dark shadows and bright highlights simultaneously, offering clearer footage under high contrast or low light situations. WDR and HDR work by taking multiple exposures of the same scene and combining them into one optimally exposed image.

Automatic Light Adjustment: Some dash cams come with an automatic light detection feature, adjusting the recording settings based on the ambient light. This is particularly useful when driving through areas with changing light conditions, like tunnels.

Lens Aperture: A camera lens’s aperture determines the amount of light that enters the sensor. A wider aperture (expressed by a lower ‘f’ number, such as f/1.8) allows more light to reach the sensor, thereby improving the camera’s performance in low-light conditions.

Field of View

The field of view in a dash camera indicates how much of the scene in front of the vehicle it can capture. It’s measured in degrees and can significantly influence what your camera will be able to record. Let’s break down why the field of view is essential in a dash cam:

Wide Angle: Dash cams typically have a wide-angle lens to capture as much of the road ahead and the periphery as possible. A broader field of view can record more details, like adjacent lanes and side roads, which can be crucial in certain situations. Models with a field of view around 140° to 160° strike a good balance, offering a wide scene without overly distorting the image.

Distortion: It’s essential to note that a very wide field of view may come with its challenges. As the field of view gets wider, the footage can start to show a ‘fish-eye’ effect. This effect can distort the video, making objects seem further away than they are, which can potentially make details like number plates harder to read.

Dual Cameras: Some dash cams come with dual cameras, one for the front and one for the rear. This gives you coverage at both ends of your vehicle, providing a comprehensive field of view.

Parking Mode

Parking mode is a valuable feature that ensures your vehicle is still monitored, even when parked and turned off. Here’s what you need to know:

Motion and Impact Detection: In parking mode, the dash cam uses sensors to detect motion or impacts near your vehicle. When it senses movement or an impact, the camera will power up and start recording, capturing potential incidents like a hit-and-run or vandalism.

Buffered Parking Mode: Some high-end dash cams offer a ‘buffered’ parking mode. This means the camera is continuously recording but only saves the footage when motion or impact is detected. Importantly, it saves several seconds before the trigger event, ensuring you don’t miss what led up to the incident.

Energy Source: To operate in parking mode, the camera needs a power source, even when the vehicle is turned off. This can be the car’s battery, but be cautious, as prolonged use can drain the battery. Many dash cams have built-in voltage meters to prevent battery drain. Alternatively, some dash cams have their own separate battery or can be hardwired to the car’s fuse box.

Legal Considerations: Before using parking mode, be sure to check the local laws, as some jurisdictions have rules about recording in public spaces. In the UK, it’s generally legal to use a dash cam’s parking mode.

Loop Recording and G-Sensor in Dash Cameras

Loop Recording

Loop recording is an essential feature found in most dash cameras that enables the device to manage storage efficiently. Without this feature, once the storage space on your dash cam was filled, you would have to manually delete old files to continue recording.

Efficient Storage Management: Loop recording automatically overwrites the oldest non-protected files on the memory card, ensuring the camera never runs out of space to record new footage. This means you can always have the most recent recordings at your disposal, without the need for constant manual maintenance.

Duration of Loops: The duration of each ‘loop’ or ‘segment’ can often be set in the camera’s settings. Common options include intervals of 1, 3, or 5 minutes. This means that your footage is saved in bite-sized chunks, which can be easier to view and manage.

Important Note: It’s worth remembering that loop recording can potentially overwrite essential footage if not appropriately managed. This is where features like the G-Sensor and manual file locking come in.

G-Sensor

The G-Sensor, also known as the accelerometer, is another significant feature in dash cams. It detects sudden changes in motion or force, whether it’s rapid acceleration, sudden braking, or impacts.

Collision Detection: In the context of a dash camera, the primary function of a G-sensor is to detect collisions. In the event of an accident, the G-sensor triggers, and the camera automatically ‘locks’ the current segment of footage, preventing the loop recording feature from overwriting it.

Sensitivity Settings: Most dash cameras allow you to adjust the sensitivity of the G-Sensor. Higher sensitivity means the sensor will react to smaller forces, while lower sensitivity requires a more significant force to trigger. Finding the right balance is crucial, as too high sensitivity may cause the sensor to trigger and lock files even during a bumpy ride or slamming of the car door.

Parking Mode Activation: The G-Sensor also plays a crucial role in parking mode. If your car is hit while parked, the G-Sensor will detect the impact, wake the camera, and start recording, ensuring you capture vital footage of the incident.

In conclusion, loop recording and the G-Sensor are key functionalities in a dash cam that work together to manage your video footage efficiently and protect crucial evidence. When choosing a dash cam, ensure these features are available and customisable to suit your needs. And remember, a high-quality memory card is also important as it works hand in hand with these features for optimal performance.
