Dash cam dictionary

GPS (Global Positioning System) allows a compatible dashcam to record your vehicle's location, speed, direction of travel, and route alongside the video footage. This information is embedded into the recording and can be viewed later using the manufacturer's playback software or app. GPS data can provide valuable context if footage is used to review a journey, investigate an incident, or verify where and when an event occurred.

FPS (Frames Per Second), also known as frame rate, refers to the number of individual images a dashcam records each second to create a video. Common frame rates include 30 FPS and 60 FPS, with higher frame rates producing smoother footage and making it easier to capture fast-moving objects, such as passing vehicles or number plates. Higher frame rates may also require more storage space, so the ideal choice depends on the level of detail you need and the recording resolution supported by the dashcam.

FOV (Field of View) refers to how much of the road and surrounding area a dashcam's lens can capture in a single frame. A wider field of view records more of the scene, including adjacent lanes and roadside activity, while a narrower field of view focuses more on what is directly ahead. Choosing the right FOV is a balance between capturing a broad area and maintaining image detail, with most quality dashcams offering a field of view that provides excellent coverage without introducing excessive edge distortion.

Some dashcams are available with one, two, or three cameras, commonly referred to as 1CH, 2CH, and 3CH systems. A 1CH dashcam records the road ahead, while a 2CH system adds a rear camera to capture vehicles behind. A 3CH system includes an additional interior camera, providing extra coverage inside the vehicle. Many interior cameras use a wide-angle fisheye lens with up to a 210° field of view, allowing them to capture not only the cabin but also much of the view through the side windows. This provides valuable footage of incidents occurring alongside the vehicle that may not be...

A dashcam battery pack is an external rechargeable battery designed to power a dashcam while the vehicle is parked, without drawing power from the vehicle's starter battery. It charges while you drive and automatically supplies power when the engine is turned off, allowing parking mode to operate for extended periods. Battery packs are an excellent option for drivers who want longer parking surveillance, maximum battery protection, or who regularly leave their vehicle parked for long periods.
