Dash Cam features

• The sensor, lens, and processor
Car dashboard cameras are built like regular common cameras. It has an image sensor, processor, camera lens and other common camera components.

• Loop Recording
Another great feature of a dash camera is the loop recording feature. This feature allows for the device to record footage continuously regardless of the storage capacity. This feature is very similar to that of surveillance cameras. This means that a car dashboard camera can continue to record non-stop by overwriting the old data when the memory is full. So, you don’t need to remove the device and erase stored video history every now and then.
More so, the loop recording feature records and saves videos in segments. For instance, the loop can record videos in 2 mins segments throughout the period of usage. This will ensure that if one segment of the video is corrupt, others are available for use.

• The G-sensor
The G-sensor is another fantastic feature of the car dashboard camera. It acts as an accelerator meter which measures the forces that act on it during changes in velocity. The G-sensor monitors your car speed and acts accordingly by safeguarding the footage once it notices a sudden change in your velocity. This feature comes handy when your vehicle is involved in an accident. Since an accident will abruptly alter your car speed, the G-sensor automatically detects this change in speed and keeps your footage record during this time. It keeps them safe and prevents them from being overwritten.

• GPS, LDWS, WiFi, and FCWS
There are some other optional accessory features that you can also consider when choosing a car dash cam. These features may come handy but are not necessarily compulsory. These features include WiFi, GPS, LDWS (Lane Departure Warning System) and FCWS (Forward Collision Warning System). Depending on your needs, one or more of these features might suit you.

• **Dedicated Power Supply**
Car dash cams use a dedicated power supply which is always connected to the vehicle either via the cigarette outlet or by manual wiring. Dash cams can operate only for a few minutes without a power source. Therefore, they are not meant to be used outside the vehicle for other purposes. More so, the camera automatically starts working once your vehicle is turned on and stops recording when you turn off.
