The basic function of a dash cam is to record your drive. Dash cameras are a unique device built specifically for vehicles. Think of it as a surveillance camera for your vehicle. Below we explain the key features you would come to expect and find when shopping for a dash cam.
Dash cams are built just like a camera. It has a processor, image sensor, camera lens, and other extra components. When shopping for one, it is important to consider the type of processor it is using, this will determine the quality. Just like computers, there are different types of processors. They range from low-end to high-end. This goes the same for image sensors.
One of the key features that makes dash cams unique is the loop recording feature. This feature is similar to that of surveillance cameras. Loop recording allows for continuous recording regardless of the memory’s capacity. This means that dash cameras are programmed to record non-stop on a loop by overwriting the earliest footage when the memory has reached its capacity. This allows the driver to never have to worry about removing the device and cleaning out the memory.
Loop recording records videos in segments. By recording in 1, 3, or 5 minute segments, this ensures that if one segment of the video becomes corrupted, the other video files will not be compromised.
Another key feature is the g-sensor. The g-sensor acts as an accelerometer, measuring the forces that act on it during changes in velocity. This means that the g-sensor measures the movement of your vehicle and responds accordingly by safeguarding footage whenever the g-sensor detects sudden or abrupt movement. This feature is ideal if your vehicle is involved in an accident. The footage involved will be locked and prevented from being overwritten.
There are many other optional features that may come with a dash camera. These features may come in handy but may also prove unnecessary. Some examples of extra features you may find are GPS, LDWS or Lane Departure Warning System, Wifi, FCWS or Forward Collision Warning System, and many others. Depending on your needs, find out if these extra features will benefit you or not.
Lastly, dash cams operate through a dedicated power supply. This means that the device is always connected to the vehicle, either through the cigarette outlet or by hardwiring it to the fuse box. Dash cams operate only a few minutes without a power source. They are not meant to be removed and used outside of the vehicle. Whenever your vehicle is turned on, the dash cam will automatically turn on and begin recording. When your vehicle is turned off, it will automatically stop recording.
