Although in popular belief, people may have this concept that any recording device may be used as dash cams, but it is always recommendable to use a purpose-built dash cam instead of hacking something together. There are several reasons why you should not consider any hand-held camera to be doubled as dashboard cameras; let's discuss them here.
Dashboard cameras - How do they work?
to understand how and why dash cams are better than general purpose cameras, it is important to understand how they work. Although, they may not appeal you with their very basic yet sturdy looks, but they are certainly here to do what they are best doing at. Like any other good quality vehicle camera, a dash cam comes with a video camera, hard-wired power inputs and a built-in or removable storage media. In most cases, such cameras don't come with an on/off switch, rather they get started once the car ignition is started (these cameras are required to be wired with the internal car key system). Once powered up, these vehicle cameras are programmed to record continuously, without any sort of extra controls.
This is indeed an amazing ...
... feature, as neither the driver nor the passengers need to remember to switch it on & off each time a car is driven. This is the biggest difference between dash cams and general-purpose cameras; where you need to start and stop recording each time whenever you are driving or not driving. Thus, dash cams are a better and smart choice here. This purpose-built device on your dashboard will capture everything that is necessary when you are driving; while a general-purpose camera is a slave of your memory and command. Imagine each-time a car is driven, you need to remember to switch on your general-purpose camera; and someday in case you forget, and a miss-happening occurs, your purpose of placing the camera at the first place isn’t served.
Media Storage:
Any general-purpose video recording device, be it a smartphone or a digital camera, require external media storage (memory cards, as they are popularly known as), to store the recorded videos in the device. Additionally, once the storage gets full, the device stops recording, unless one clears up the memory card, or replace the same with a new one. Thus, when you consider using a smartphone or a digital camera to use as your dashboard camera, you need to also consider having the hassle to clear or change the storage media each time when it's full; as the device would stop recording. On the contrary, you do not have to face any such issue with purpose-built dash cam, because they come with the facility to automatically overwrite the oldest files which make them never stop recording and making them truly “set and forget” solutions.
