Put one on your windshield or purchase a whole surveillance system, it’s your choice. A dash cam consists of one camera and a display LED to help you set it. Some dash cams offer a package of a display and 2 cameras that you can mount both on your front windshield or the back windshield to give a good view of the rear part of your vehicle.

After mounting the dash cams, you will plug the camera into the recording system module and connect it to the vehicle’s power supply. You can power the cameras via the cigarette lighter charging port or have it soldered into the fuse box. Once it is powered and connected to the recording module, you can synchronize it to your phone using the camera recommended app if it has such features. To turn it on, you only need to start the car and the camera will auto-start. You can also control the camera and set up the features via the app if you want to.

Make sure you complete the recording module with a micro SD card so it can store the recordings. A 16gb micro SD card can store approximately 2-hour 4K video recordings. But the number highly depends on the resolution of the video. The videos are usually stored in segments that will be reused should the micro SD card runs out of space, but you can always customize this option if you need a full recording instead of segments. You can watch the recorded videos on the app or—if included in your purchase—on the LED display on the recorder.

Before you purchase one, do check if the dash cam has a crash detection system; this feature is highly useful to prevent the system from erasing important videos. Once the camera detected that the vehicle has gotten into a crash, it will keep any videos where the crash happened, and even after it did. The kept segments will not be reused by future recordings.

It helps you give a piece of solid evidence for trial and insurance claim proceedings, like a parking surveillance system, or monitoring the passenger cabin while you are driving. Most dash cams are equipped with features like GPS Tracking, Parking Surveillance, and crash detection system to allow you to have peace of mind whether you are away or in your vehicle. It is simply an investment that is worth every dime.
